<div>'''Ogg Skeleton''' provides structuring information for multitrack [[Ogg]] files. It is compatible with Ogg [[Theora]] and provides extra clues for synchronization and content negotiation such as language selection. Skeleton version 4.0 also provides keyframe indexes to enable optimal seeking over high-latency connections, such as the internet. (The previous version was [[Ogg Skeleton 3]].)<br />
<br />
Ogg is a generic container format, enabling interleaving of several tracks of frame-wise encoded content in a time-multiplexed manner. As an example, an Ogg physical bitstream could encapsulate several tracks of video encoded in Theora and multiple tracks of audio encoded in Speex or Vorbis or FLAC at the same time. A player that decodes such a bitstream could then, for example, play one video channel as the main video playback, alpha-blend another one on top of it (e.g. a caption track), play a main Vorbis audio together with several FLAC audio tracks simultaneously (e.g. as sound effects), and provide a choice of Speex channels (e.g. providing commentary in different languages). Such a file is generally possible to create with Ogg, it is however not possible to generically parse such a file, seek on it, understand what codecs are contained in such a file, and dynamically handle and play back such content. <br />
<br />
Ogg does not know anything about the content it carries and leaves it to the media mapping of each codec to declare and describe itself. There is no meta information available at the Ogg level about the content tracks encapsulated within an Ogg physical bitstream. This is particularly a problem if you don't have all the decoder libraries available and just want to parse an Ogg file to find out what type of data it encapsulates (such as the "file" command under *nix to determine what file it is through magic numbers), or want to seek to a temporal offset without having to decode the data (such as on a Web server that just serves out Ogg files and parts thereof).<br />
<br />
Ogg Skeleton is designed to overcome these problems. Ogg Skeleton is a logical bitstream within an Ogg stream that contains information about the other encapsulated logical bitstreams. For each logical bitstream it provides information such as its media type, and explains the way the granulepos field in Ogg pages is mapped to time. <br />
<br />
Seeking in an Ogg file is typically implemented as a bisection search for the seek target timestamp. However when seeking over a high latency connection, such as the internet, such searches can be slow. Some bitstreams, notably Theora, have keyframes, and so in order to seek to a given temporal offset in a Theora stream, you must first perform a bisection search to find the target Theora frame, determine its keyframe, and then perform another bisection search to locate that keyframe and decode forwards to the temoporal offset. This can be very slow. The Ogg Skeleton 4.0 provides an index of keyframes, and indexes periodic samples on streams without the concept of a keyframe, so that seeking over high-latency connections can simply be performed optimally with "one hop".<br />
<br />
Ogg Skeleton is also designed to allow the creation of substreams from Ogg physical bitstreams that retain the original timing information. For example, when cutting out the segment between the 7th and the 59th second of an Ogg file, it would be nice to continue to start this cut out file with a playback time of 7 seconds and not of 0. This is of particular interest if you're streaming this file from a Web server after a query for a temporal subpart such as in http://example.com/video.ogv?t=7-59 .<br />
<br />
=== Previous version ===<br />
<br />
The previous version of Ogg Skeleton was version 3, and its specification can be found on the wiki page [[Ogg Skeleton 3]], or at [http://svn.annodex.net/standards/draft-pfeiffer-oggskeleton-current.txt http://svn.annodex.net/standards/draft-pfeiffer-oggskeleton-current.txt].<br />
<br />
=== How to describe the logical bitstreams within an Ogg container? ===<br />
<br />
The following information about a logical bitstream is of interest to contain as meta information in the Skeleton:<br />
* the serial number: it identifies a content track<br />
* the mime type: it identifies the content type<br />
* other generic name-value fields that can provide meta information such as the language of a track or the video height and width<br />
* the number of header packets: this informs a parser about the number of actual header packets in an Ogg logical bitstream<br />
* the granule rate: the granule rate represents the data rate in Hz at which content is sampled for the particular logical bitstream. Note that when using this to interpret timestamps, the granulepos of a data page must first be parsed to extract a granule value using the method described in [[GranulePosAndSeeking]]. This value can then be mapped to time by calculating "granules / granulerate".<br />
* the preroll: the number of past content packets to take into account when decoding the current Ogg page, which is necessary for seeking (vorbis has generally 2, speex 3)<br />
* the granuleshift: the number of lower bits from the granulepos field that are used to provide position information for sub-seekable units (like the keyframe shift in theora)<br />
* a basetime: it provides a mapping for granule position 0 (for all logical bitstreams) to a playback time; an example use: most content in professional analog video creation actually starts at a time of 1 hour and thus adding this additional field allows them retain this mapping on digitizing their content<br />
* a UTC time: it provides a mapping for granule position 0 (for all logical bitstreams) to a real-world clock time allowing to remember e.g. the recording or broadcast time of some content<br />
<br />
=== How to allow the creation of substreams from an Ogg physical bitstream? ===<br />
<br />
When cutting out a subpart of an Ogg physical bitstream, the aim is to keep all the content pages intact (including the framing and granule positions) and just change some information in the Skeleton that allows reconstruction of the accurate time mapping. When remultiplexing such a bitstream, it is necessary to take into account all the different contained logical bitstreams. A given cut-in time maps to several different byte positions in the Ogg physical bitstream because each logical bitstream has its relevant information for that time at a different location. In addition, the resolution of each logical bitstream may not be high enough to accommodate for the given cut-in time and thus there may be some surplus information necessary to be remuxed into the new bitstream.<br />
<br />
The following information is necessary to be added to the Skeleton to allow a correct presentation of a subpart of an Ogg bitstream:<br />
* the presentation time: this is the actual cut-in time and all logical bitstreams are meant to start presenting from this time onwards, not from the time their data starts, which may be some time before that (because this time may have mapped right into the middle of a packet, or because the logical bitstream has a preroll or a keyframe shift)<br />
* the basegranule: this represents the granule number with which this logical bitstream starts in the remuxed stream and provides for each logical bitstream the accurate start time of its data stream; this information is necessary to allow correct decoding and timing of the first data packets contained in a logcial bitstream of a remuxed Ogg stream<br />
<br />
=== Keyframe indexes for faster seeking ===<br />
<br />
Seeking in an Ogg file is typically implemented as a bisection search over the pages in the file. The bisection method above works fine for seeking in local files, but for seeking in files served over the Internet via HTTP, each bisection or non sequential read can trigger a new HTTP request, which can have very high latency, making seeking very slow. Seeking is further complicated by the fact that packets often span multiple <br />
Ogg pages, and that Ogg pages from different streams can be interleaved <br />
between spanning packets. <br />
<br />
Each content track has a separate index, which is stored in its own packet in the Skeleton 4.0 track. The index for streams without the concept of a keyframe, such as Vorbis streams, can instead record the time position at periodic intervals, which achieves the same result. When this document refers to keyframes, it also implicitly refers to these independent periodic samples from keyframe-less streams. <br />
<br />
Because all the Skeleton track's index packets appear in the header pages of the Ogg segment, all the keyframe indexes are immediately available once the header packets have been read when playing the media over a network connection. <br />
<br />
For every content stream in an Ogg segment, the Skeleton provides seek algorithms with an index, or ordered table of "key points". A key point is intrinsically associated with exactly one stream, and stores the offset, o, of the last page which lies before all data required to decode the keyframe, as well as the presentation time of the keyframe t, as a fraction of seconds.<br />
<br />
The offset is relative from the beginning of the Ogg segment, and is exactly the first byte of a page in the indexed stream, so if you seek to a keypoint's offset and don't find the beginning of a page there, or you find a page from another stream, you can assume that the Ogg segment has been modified since the index was constructed, and the index can be considered invalid. The time t is the keyframe's presentation time corresponding to the granulepos, and is represented as a fraction in seconds. Note that if a stream requires any preroll, this will be accounted for in the time stored in the keypoint. <br />
<br />
The Skeleton 4.0 track contains one index for each content stream in the file. To seek in an Ogg file which contains keyframe indexes, first construct the set which contains every active streams' last keypoint which has time less than or equal to the seek target time. This tells you a known point on every stream which lies before the seek target. Then from that set of key points, select the key point with the smallest byte offset. You then verify that there's a page from the keypoint's stream found at exactly that offset, and if so, you can begin decoding. You are guaranteed to pass keyframes on all streams with time less than or equal to your seek target time while decoding up to the seek target. However if you don't encounter a keyframe with the same presentation time as is stored in the keypoint, then the index is invalid (possibly the file has been changed without updating the index) and you must either fallback to a bisection search, or keep decoding if you've landed "close enough" to the seek target.<br />
<br />
Be aware that you cannot assume that any or all Ogg files will contain keyframe indexes, so when implementing Ogg seeking, you must gracefully fall-back to a bisection search or other seek algorithm when the index is not present, or when it is invalid.<br />
<br />
The Skeleton 4.0 index packets also stores meta data about the segment in which it resides. It stores the timestamps of the first and last samples in its track. This also allows you to determine the duration of the indexed Ogg media without having to decode the start and end of the Ogg segment to calculate the difference (which is the duration). With the index packets storing the start and end times of every track, you can calculate the duration as the end time of the last active stream minus the start time of first active stream.<br />
<br />
The Skeleton 4.0 BOS packet contains the length of the indexed segment in bytes. This is so that if the seek target is outside of the indexed range, you can immediately move to the next/previous segment and either seek using that segment's index, or narrow the bisection window if that segment has no index. You can also use the segement length to verify if the index is valid. If the contents of the segment have changed, it's highly likely that the length of the segment has changed as well. When you load the segment's header pages, you should check the length of the physical segment, and if it doesn't match the length stored in the Skeleton header packet, you know that either the index is out of date, or the file has been chained since indexing.<br />
<br />
The Skeleton 4.0 BOS packet also contains the offset of the first non header page in the Ogg segment. This means that if you wish to delay loading of an index for whatever reason, you can skip forward to that offset, and start decoding from that offset forwards.<br />
<br />
When using the index to seek, you must verify that the index is still correct. You can consider the index invalid if any of the following are true:<br />
<br />
* The segment doesn't end at the segment length offset stored in the Skeleton BOS packet (note that a new "link" in a "chain" can start at the end of the segment), or<br />
* after a seek to a keypoint's offset, you don't land exactly on a page boundary, or<br />
* after a seek to a keypoint's offset, you don't land on a page which belongs to that keypoint's stream.<br />
<br />
While loading the Skeleton BOS header, you should always check the Skeleton version field to ensure your decoder correctly knows how to parse the Skeleton track. <br />
<br />
Be aware that a keyframe index may not index all keyframes in the Ogg segment, it may only index periodic keyframes instead.<br />
<br />
<br />
=== Ogg Skeleton version 4.0 Format Specification ===<br />
<br />
Adding the above information into an Ogg bitstream without breaking existing Ogg functionality and code requires the use of a logical bitstream for Ogg Skeleton. This logical bitstream may be ignored on decoding such that existing players can still continue to play back Ogg files that have a Skeleton bitstream. Skeleton enriches the Ogg bitstream to provide meta information about structure and content of the Ogg bitstream.<br />
<br />
The Skeleton logical bitstream starts with an ident header that contains information about all of the logical bitstreams and is mapped into the Skeleton bos page.<br />
The first 8 bytes provide the magic identifier "fishead\0".<br />
After the fishead follows a set of secondary header packets, each of which contains information about one logical bitstream. These secondary header packets are identified by an 8 byte code of "fisbone\0". The Skeleton logical bitstream has no actual content packets. Its eos page is included into the stream before any data pages of the other logical bitstreams appear and contains a packet of length 0.<br />
<br />
The fishead ident header looks as follows ([http://annodex.org/w/images/3/39/FishHeads.JPG inspiration]):<br />
<br />
0 1 2 3<br />
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1| Byte<br />

The version fields provide version information for the Skeleton track, currently being 4.0 (the number having evolved within the Annodex project).<br />
Presentation time and basetime are specified as a rational number, the denominator providing the temporal resolution at which the time is given (e.g. to specify time in milliseconds, provide a denominator of 1000).<br />

+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| Message header fields ... | 52-<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
<br />
The mime type is provided as a message header field specified in the same way that HTTP header fields are given, e.g. "Content-Type: audio/vorbis". Message header fields are terminated/delimited by "\r\n". Further meta information (such as language and screen size) are also included as message header fields. The offset to the message header fields at the beginning of a fisbone packet is included for forward compatibility - to allow further fields to be included into the packet without disrupting the message header field parsing.<br />
The granule rate is again given as a rational number in the same way that presentation time and basetime were provided above.<br />
<br />
The following message headers are compulsory in Skeleton 4.0:<br />
* Content-type: mime type of the content encoded in this stream, e.g. audio/vorbis, video/theora, etc. The mime types in use here are listed at http://wiki.xiph.org/MIME_Types_and_File_Extensions#Codec_MIME_types.<br />
* Role: describes the function of this track. Common examples are "video/main", "audio/main", "text/caption". For a complete list of possibilities, see http://wiki.xiph.org/SkeletonHeaders#Role.<br />
* Name: a unique free text string which can be used to directly address the track in scripting applications, such as an HTML5 viewer.<br />
<br />
For more message headers, see [[SkeletonHeaders]].<br />
<br />
Before the Skeleton EOS page in the segment header pages come the Skeleton 4.0 keyframe index packets. There should be one index packet foreach content track in the Ogg segment, but index packets are not required for a Skeleton 4.0 track to be considered valid. Each keyframe in the index is stored in a "keypoint", which in turn stores an offset, and timestamp. In order to save space, the offsets and timestamps are stored as deltas, and then variable byte-encoded. The offset and timestamp deltas store the difference between the keypoint's offset and timestamp from the previous keypoint's offset and timestamp. So to calculate the page offset of a keypoint you must sum the offset deltas of up to and including the keypoint in the index.<br />
<br />
The variable byte encoded integers are encoded using 7 bits per byte to store the integer's bits, and the high bit is set in the last byte used to encode the integer. The bits and bytes are in little endian byte order. For example, the integer 7843, or 0001 1110 1010 0011 in binary, would be stored as two bytes: 0xBD 0x23, or 1011 1101 0010 0011 in binary.<br />
<br />
Each index packet contains the following: <br />
<br />
0 1 2 3<br />
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1| Byte<br />

+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
<br />
The fields of the index packet are as follows:<br />
<br />
# Identifier 6 bytes: "index\0". Bytes [0...5].<br />
# The serialno of the stream this index applies to, as a 4 byte field. Bytes [6...9]<br />
# The number of keypoints in this index packet, 'n' as a 8 byte unsigned integer. This can be 0. Bytes [10...17].<br />
# The presentation time denominator for this stream, as an 8 byte signed integer. All timestamps, including keypoint timestamps, first and last sample timestamps are fractions of seconds over this denominator. This must not be 0. Bytes [18...25].<br />
# First-sample-time numerator: 8 byte signed integer representing the numerator for the presentation time of the first sample in the track. Bytes [26...33]<br />
# Last-sample-time numerator: 8 byte signed integer representing the end time of the last sample in the track. Bytes [34...41]<br />
# 'n' key points, starting with the first keypoint at byte 42. Each keypoint contains, in the following order:<br />
## the keyframe's page's byte offset delta, as a variable byte encoded integer. This is the number of bytes that this keypoint is after the preceeding keypoint's offset, or from the start of the segment if this is the first keypoint. The keypoint's page start is therefore the sum of the byte-offset-deltas of all the keypoints which come before it.<br />
## the presentation time numerator delta, of the first key frame which starts on the page at the keypoint's offset, as a variable byte encoded integer. This is the difference from the previous keypoint's timestamp numerator. The keypoint's timestamp numerator is therefore the sum of all the timestamp numerator deltas up to and including the keypoint's. Divide the timestamp numerator sum by the timestamp denominator stored earlier in the index packet to determine the presentation time of the keyframe in seconds.<br />
<br />
The key points are stored in increasing order by offset (and thus by presentation time as well).<br />
<br />
The byte offsets stored in keypoints are relative to the start of the Ogg bitstream segment. So if you have a physical Ogg bitstream made up of two chained Oggs, the offsets in the second Ogg segment's bitstream's index are relative to the beginning of the second Ogg in the chain, not the first. Also note that if a physical Ogg bitstream is made up of chained Oggs, the presence of an index in one segment does not imply that there will be an index in any other segment. <br />
<br />
The first-sample-time and last-sample-time are rational numbers, in units of seconds. If the denominator is 0 for the first-sample-time or the last-sample-time, then that value was unable to be determined at indexing time, and is unknown.<br />
<br />
The exact number of keyframes used to construct key points in the index is up to the indexer, but to limit the index size, we recommend including at most one key point per every 64KB of data, or every 1000ms, whichever is least frequent.<br />
<br />
=== Further restrictions === <br />
<br />
A further restriction on how to encapsulate Skeleton into Ogg is proposed to allow for easier parsing:<br />
* there can only be one Skeleton logical bitstream in a Ogg bitstream.<br />
* the Skeleton bos page is the very first bos page in the Ogg stream such that it can be identified straight away and decoders don't get confused about it being e.g. Ogg Vorbis without this meta information<br />
* the bos pages of all the other logical bistreams come next (a requirement of Ogg)<br />
* the secondary header pages of all logical bitstreams come next, including Skeleton's secondary header packets (the fisbone and index packets)<br />
* the Skeleton eos page end the control section of the Ogg stream before any content pages of any of the other logical bitstreams appear.<br />

<div>==TrekStor==<br />
There are many more portable players by TrekStor than the i.beat 500 supporting ogg vorbis.<br />
<br />
Please add products to the main page.<br />
<br />
== LG players ==<br />
I think LG's player MF-FM30 looks nice. BUT, does it have support for UMS (the products homepage doesn't say so so I guess not) or does there software work in Linux? Somebody who knows?<br />
Hannulan - 23:48, 1 oktober 2006<br />
<br />
== List of top five players ==<br />
It would be a good idea to have a few (five?) players at the top with images that are considered to be the best *recent* devices. I don't think any of the MP3 using masses will use this page to choose their next music player unless it lists recent devices, and presents a choice of five or six at the top, with images, and links to sites that they can buy them from. Also, could someone put up a notice to remind people it's not OGG, or Ogg! It's Ogg Vorbis, or if you must, Vorbis. - thehumanerror 25th December 2006<br />
<br />
I totally agree with the above. This page was next to useless for me when I was shopping for a Vorbis player since I was overwhelmed with choices. Add to that the fact that many products have been discontinued or cannot be bought new and there's a recipe for disaster. - erpo41 October 17th, 2007<br />
<br />
I also agree with the above; the primary reason I am not using Ogg Vorbis (I keep a parallel collection of mp3 and flac files) is I cannot easily find a portable player. I don't know that reorganizing this wiki page will help. I did comb through this page; basically all of the listed hard disk players are from one off manufacturers or not being manufactured any more. There are plenty of nice flash storage based devices and cell phones (from Samsung and others), but that is not what I am looking for. Also, I'm not interested in hacking my iPod. (I do embedded linux development enough at work; I'll pay someone else to get my media player working). Until this is addressed, Ogg Vorbis is going to remain out of use; which is a shame because for every other reason it is the best (in my opinion). --Kevin Holzer, January 10, 2009<br />
<br />
:Yes. This is a good idea. Create a section at the top. Polish it well. And perhaps add a free-licensed photo. Anyone up for it?--[[User:Saoshyant|Ivo]] 06:41, 17 October 2007 (PDT)<br />
<br />
I would rather see just a simple feature matrix (sorted so that unavailable devices are listed at the bottom, or just not listed at all). See talk below. Maybe preferred choises could be raised to the top thought! I agree that current list is quite unusable.<br />
<br />
== Recording in Vorbis ==<br />
<br />
I would like to know which Players can '''record''' in Vorbis?! -- [[User:217.186.150.213|217.186.150.213]] 17:03, 26 Dec 2004 (PST)<br />
<br />
:Ditto. Absolutely vital information. Do any of the players listed also record in Vorbis? If anyone has experience with A player, please state specifically whether it does or does not record in Vorbis.[[User:Nickhill|Nickhill]] 15:04, 4 June 2006 (PDT)<br />
<br />
::Never heard of one that does, and there isn't a fixed point reference encoder, which makes it unlikely.<br />
<br />
== Pretec Allegro may need firmware update ==<br />
<br />
I recently purchased a Pretec Allegro, but was unable to play Oggs for three months, until the firmware update was made available on 14 or 15 March 2005. Now it works well! (So far, listening to -q3 Oggs). I'd hope that units purchased after this date already has the firmware update, but you never know. Installing the update is as simple as placing the .rom on the USB-storage-device media (eg flash disk), starting up the unit, and pressing the play button. -- Hugo van der Merwe<br />
: How much battery runtime do you get playing Oggs compared with playing mp3? [[User:Phr|Phr]] 02:05, 27 Aug 2005 (PDT)<br />
<br />
== Any player with Removable Memory Cards ==<br />
<br />
The NexBlack (see [[PortablePlayers]] ) has removable compact flash and batteries.<br />
<br />
Every single Vorbis-capable portable player out there seems to come with built-in flash memory. Which is stupid, because I don't want to fire up my computer and plug in the player every time I get tired of the tracks on my player. Plus flash memory has a limited lifetime (write cycles) and so does your player with built-in memory. The same applies for built-in rechargable batteries. <br />
<br />
Now when would you ever need to buy your second device without any moving parts if you could just change flash memory and batteries? Ok, that's the industrie's point of view but not mine. I want to go on vacation with music and batteries for one week of non-stop music - without a power source or computer nearby.<br />
<br />
So, any hint to where I might find a portable audio player that can play back ogg vorbis files and uses SD flash cards (and preferably AAA-batteries) would be greatly appreciated.<br />
* Me too! If the [http://enox.co.kr/2004/eng/product/product_830_01.asp Enox EMX-830] took SD cards it'd be perfect. --[[User:Rgm|rgm]] 14:41, 7 Nov 2005 (PST)<br />
<br />
* SanDisk Sansa e250/e260/e270/e280 has a microSD-card slot. With ROCKbox it plays Ogg/Vorbis and more.[[User:Nostromo|Nostromo]] 15:26, 29 October 2007 (PDT)<br />
<br />
<br />
----<br />
<br />
The Pretec Allegro is not the slickest player out there, it's LCD backlight seems to give off a high-pitched whine, which not everyone can hear (it kind-of screams in my ears though, so I put the backlight timer on 1 second so it doesn't scream too long). It is, however, the only one I now know of that can play Oggs, and uses removable media. If you want a nicely portable device, you have to use Pretec's "iDisk tiny" usb flash disk, the only thing that will fit inside. You can also, however, connect some USB SD-card reader with it's cable, then listen to Oggs off of SD. A little unwieldy, but, it works, and is the only thing *I* know of. (I stopped following developments in December though, when I bought it...)<br />

== Samsung / Yepp ==<br />
<br />
Moved to [[Talk:PortablePlayersSamsungYepp]]<br />
<br />
== UniBrain iZak ==<br />
<br />
Apologies if this is the wrong place for this; I'm new to wikis.<br />
<br />
The UniBrain iZak was added, then removed recently, with the comment that it doesn't claim to play Ogg Vorbis.<br />
<br />
The FAQ is available here: [http://www.unibrain.com/support/FAQ_iZak.htm iZak FAQ] and Question/Answer 24 says:<br />
<br />
'22. Can iZak™ support OGG audio files?<br />
<br />
Yes, iZak™ fully supports OGG playback using the latest firmware.'<br />
<br />
:I was the one that removed it. In their specs linked from the main page, I saw that they listed only MP3 and WMA support for music formats. Obviously they need to update their promotional material! I went ahead and added the iZak back in, making a point to mention that the most current version of the firmware now supports Ogg Vorbis and linking to their FAQ as evidence. [[User:Saxifrage|Saxifrage]] 02:36, 5 May 2005 (PDT)<br />
<br />
:Splendid. I didn't want to just stick it back after it had been taken out.--[[User:Ipl|Ipl]] 05:14, 5 May 2005 (PDT)<br />
<br />
== Entempo Spirit ==<br />
<br />
This inexpensive player from Entempo had listed Vorbis as a "Supported Audio Format", but the device will not index the Vorbis files into it's menus -- let alone play the files. Tested with both the stock and most recent firmware, May 29, 2005. Vendor had been contacted and removed Vorbis support claims from their website, but has not provided any resolution to customers which purchased the product expecting this support. The company's webpage has disappeared as of Feb 2006.<br />
<br />
== Lexar LDP-800 dropped ==<br />
It seems that Lexar have abondoned the LDP-800. The following was posted by a user on [http://www.dapreview.net/comment.php?comment.news.1055 dapreview.net]<br />
" Unfortunately, lexar will not offer the LDP-800, but will focus instead<br />
on its existing LDP Players that already offer appealing features and<br />
benefits to meet a variety of consumer needs."<br />
Shame.--[[User:Ipl|Ipl]] 06:15, 22 Jul 2005 (PDT)<br />
<br />
There's more info on that dapreview thread that indicates some confusion within Lexar. Currently, it looks like the release is going to happen in early September.<br />
<br />
Update 2005-11-11: after inquiries to Lexar's "new products" personnel, I received a telephone message that the LDP-800 will definitely "is not going to see the light of day." Ask me if you want details. I agree that it's a shame since this looked to be an outstanding product. --[[User:dfavro|dfavro]]<br />
<br />
== Hong Kong Dream-tech Electronic DT-202, works? please confirm ==<br />
http://hkdream-tech.com<br />
An ebay seller says that it can reproduce Vorbis. This is unconfirmed. In the manufacturer web it says: MP3, WMA, WAV, DMV and etc. <br />
<br />
Some webpage also says that it works on Windows, Mac and Linux. Also unconfirmed.<br />
Further investigation required.<br />
<br />
== Trekstor i.Beat Cube ==<br />
This player seems to be very similar to the Samsung Yepp YP-T6, possibly with the [[#Yepp_MT-6X|same problems]] regarding Vorbis playback. Trekstor has moved [http://www.trekstor.de/en/produkte/mp3-player/ibeat-cube.html info about this player] from "MP3-Player" to the "Archive" section which propably means that it is not produced anymore.<br />
<br />
== The Muzio jm300 / jm-300 does NOT play Vorbis ==<br />
<br />
NB this is the jm-300 (not 100 or 200)<br />
<br />
I bought this a month ago. I've been unable to play Vorbis files on<br />
it. It simply shows these as 'etc' files and skips over them.<br />
<br />
Pitty really, this was the main reason I chose this player.<br />
<br />
I've seen lots of discussion about the muzio playing oggs, is there<br />
anybody there who owns a jm300 and is actually playing oggs ? I can't<br />
help think I've juts missed something basic.<br />
<br />
== Layout of the PortablePlayers list and Feature matrix ==<br />
It's gone! I've moved this discussion to [[Talk:PortablePlayersv2]]. [[User:Imalone|Imalone]] 10:55, 18 November 2006 (PST)<br />
<br />
:Is there something very wrong with those proposals? I mean, is there any reason why (even a simple) feature matrix just could not be applied right now? It would probably solve 'list of top 5 players' problem above too. Just list something basic from the main features, name, size, weight, price, battery (internal, aa, aaa, ..), capasity, flash card type (sd, microsd, ..) , availability (current or discontinued), supported formats, charging (usb or propietary or none). Link to the longer comments. No complicated sorting or anything too fancy. No icons. Name can be a abbreviation to save space, use it as a link to current comments.<br />
<br />
== NEXBlack out ==<br />
<br />
I got my NEXBlack player today from Frontier Labs. It is a nice gadget with sleek design. They have corrected the occasional snap-sounds that came between tracks and it is overall more usable now. Vorbis-files also play fine, but the current firmware doesn't have Vorbis-tag reader, which is somewhat major drawback. The music selection works through mp3-tags and you can select by album, artist, genre and playlist, but since Vorbis tags won't work you have to select "unordered" to play them. Vorbis-files are all listed in one big list. I hope they either implement a Vorbis-tag reader or revert to old Nex IIe system where you could select by folder in the flash disc. But for the cheap price ($89), it is a good player... waiting for a new firmware..<br />
<br />
== Sumvision M18/S1 ==<br />
<br />
I've just got the 2GB Sumvision and it plays the OGG files I've tested so far. Should I add it to the list? [[User:Steevc|Steevc]] 04:05, 19 April 2007 (PDT)<br />

<br />
Hi,<br />
<br />
IMHO the PortablePlayers page is too long. I want to split it into several pages for each main section. Like [[PortablePlayers/Flash]], [[PortablePlayers/Harddisk]] etc.. Sure, one have to fix some links then, but I am convinced this step would increase the usability a lot.<br />

Why is there no listing under software of paranoia or cdparanoia? Also, there is no listing on the main xiph.org page. Is that software acknowlegded? --[[User:WhiteDragon|WhiteDragon]] 19:52, 9 September 2006 (PDT)<br />

== Suggestion :-O ==<br />
First I want to congratulate you on the wonderful work being done. Thank you very much :-)<br />
Please allow anonymous edits (like wikipedia does) b'caus i'm too lazy to login :-)<br />
<br />
:I'll give you the benefit of the doubt and assume the ton of hidden links I just culled has nothing to do with you... I can't speak for the people running Xiph but requiring a login reduces some of the flood of spam that shows up here, and Wikipedia has many more resources available to deal with it than this wiki does.

== Proposal for a developer section ==<br />
<br />
As more developers start to "get it" about how ultra cool Ogg / Vorbis / Theora / etc is, wouldn't it be great to have a wiki section devoted to helping these budding programmers along? eg: i've written some nice code i'd be happy to share. Could contain a programming FAQ, how-to's, and real code. Thoughts? [[User:Davec|Davec]] 13:44, 6 December 2006 (PST)<br />

== Why CamelCase? ==<br />
<br />
MediaWiki supports free links, why are most page titles in the CamelCase format? - [[User:Sikon|Sikon]] 05:34, 27 February 2007 (PST)<br />
:CamelCase? I don't see what you mean. If you think something's wrong, you may go ahead and change it. That's what wikis are for.--[[User:Saoshyant|Saoshyant]] 05:37, 27 February 2007 (PST)<br />
:[[WhatHappened|Historical reasons]]. The original wiki used software that only supported [http://c2.com/cgi/wiki?CamelCase CamelCase]. For new pages it is fine to use free links. I suggest not renaming pages, as many of them have good search ranking. [[User:Andrel|Andrel]] 07:03, 27 February 2007 (PST)<br />
I see now. And thanks for the WhatHappened link, Andrel. I managed to recover two pages so far from web archive. I wonder if I'll savage it further.--[[User:Saoshyant|Saoshyant]] 08:28, 27 February 2007 (PST)<br />

== ICECast2 vs vBulletin ==<br />
<br />
Hi there,<br />
Fisrt let me thank you all the great work and the self performance over the ICECast streaming server<br />
<br />
I also Wonder if anyone had included ICECast directly into a vBulletin board having it worked from there on ..meaning enbable to use same username,permission and prefference from the database itself running on MySQL 5 having as if setting permission on for a usergroupe from there to enable them streaming out on your ICECast server and others can apply and yet just participate into the main forum itself<br />
<br />
I do have both running-up over my dedicated server now meanwhile if any would want to help me out creating like this hack or template am willing to give them all access for working over it <br />
can YOU imagine how friendly and powerful that ICECast would mean then<br />
<br />
hey give me a shout if willing to try it<br />

== News ==<br />
<br />
Hi,<br />
<br />
I would really strongly suggest adding this to your news items... Someone has made a graphical interface for ffmpeg2theora at http://www.softpedia.com/get/Multimedia/Video/Other-VIDEO-Tools/GFrontEnd-for-ffmpeg2theora.shtml<br />
<br />
I don't know the technical difficulties of building such a tool, but regardless, the ability for a common Windows user like myself to be able to just easily convert a proprietary file format to Ogg-Theora is really cool... I tested it out on the sample WMV file that came with this laptop, and the converted file worked great in Cortado... Of course, news about programs that allow one to record directly to Ogg-Theora would be even better, but this is still very important, imo... [[User:Brettz9|Brettz9]] 20:56, 4 July 2007 (PDT)<br />
<br />
== .NET :-( ==<br />
<br />
> I would really strongly suggest adding this to your news items<br />
<br />
Check it out: > Requirements: .NET Framework 2.0<br />
<br />
Also, with 1.5 MiB size it's bigger than FFMPEG2THEORA itself (1.3 MiB after recompressing with UPX 3.0 --ultra-brute) - not that VERY good IMHO.<br />
<br />
: Sorry, do you mean MB as in Megabytes? That's a drop in the bucket of most hard drives nowadays, no? And .NET was already on my system for something I had downloaded earlier (not sure what, but maybe others may have it already too). My interest in seeing it announced is not how well it is implemented--if there are better alternatives let them be known--but that such a tool exists and it works (at least if you get the requirements).<br />
<br />
== MiB ||| .NET ==<br />
<br />
> Sorry, do you mean MB as in Megabytes?<br />
<br />
NO. [[http://en.wikipedia.org/wiki/Binary_prefix]]<br />
<br />
> And .NET was already on my system for something I had downloaded earlier (not sure what, but maybe others may have it already too)<br />
<br />
I don't have .NET and don't like it :-( Finally, the important thing is the FFMPEG2THEOA core and it works perfectly for me without .NET ;-)<br />
<br />
== Link to Games in Demonstrations Section? ==<br />
<br />
Shouldn't there be a link to [[Games_that_use_Theora]] in the section with other demonstrations? Maybe there's not enough games listed on the page to warrant it?<br />
--[[User:Sim9|Sim9]] 11:47, 27 October 2007 (PDT)<br />
<br />
:Yes. There's only two games listed right now. I'm pretty sure there's more out there. Sim9, can you help us listing more games?--[[User:Saoshyant|Ivo]] 11:56, 28 October 2007 (PDT)<br />
<br />
::I'm sure you're right, there ''has'' to be more than two. Theora (and Vorbis) is now by default included in the Torque game engine, so there must be a lot of games using it by now. I just polled the Torque community to see if they know of any to help us fill up the list with some successful integrations! --[[User:Sim9|Sim9]] 19:02, 29 October 2007 (PDT)<br />
<br />
== Add xvid it's opensource ==<br />
<br />
Please add xvid to usable video format in ogv and others.<br />
It's an open source, mature codec and doesn't have encoder problems theora currently has.<br />
Embedding it makes possible to show off ogv files with a codec that shows the tru power of ogv.<br />
<br />
Please make it possible to put this in, so .ogv can be used immediately with xvid and vorbis/speex/flac to create a mature and temporary solution until theora 1.0 hits the digital streets.<br />
Then users can just batch convert it with their applications whenever they feel/want to do it.<br />
(When they think theora is ready.)<br />
Could someone please look into this and tell me if this is possible and/or will be integrated?<br />
--[[User:Vmol|Vmol]] 1 February 2008 <br />
<br />
:Vmol, you should read about the issues a bit before filling up the whole wiki with so many questions. Most of your questions, concerns and statements have already been thought about. In this case here, Xvid cannot be considered because it is a patented format. That means it's not a free format like Theora and Xiph cannot use it. Theora is currently now undergoing the last stages of beta to version 1.0 and quality is already at pair with Xvid. Also, users can't simply transcode from one video format to another; you lose quality everytime you do it, because most video formats are lossy.--[[User:Saoshyant|Ivo]] 12:37, 2 February 2008 (PST)<br />
<br />
== Random access Ogg Vorbis decoder written in Java. ==<br />
<br />
And I am very glad that now you have an encoder written in Java. Can vorbis-java-1.0.0 also do the decoding?<br />
Is there an example of how to use vorbis-java decoder?<br />
If yes, can it seek, i.e. decode an Ogg Vorbis bitstream from a random position?<br />
--[[User:Sergey|Sergey]] 12:53, 9 February 2008 (PST)<br />
<br />
== For lossless video compression, make it possible to have Lagarith codec as video ==<br />
<br />
Lagarith is a lossless video codec. Please support it, with supporting I mean that it can be used in the ogg and annodex containers as a native video format.<br />
--[[User:Vmol|Vmol]] 4 May 2008 <br />
<br />
:There is also HuffYUV besides Lagarith. Also the new Dirac codec supports lossless compression, reportedly better than anything else. Agree, a lossless codec should be added. Just carefully select one of them ;-) [[User:DOS386|DOS386]] 01:31, 4 May 2008 (PDT)<br />
<br />
:: Lossless compression would still be a good thing to have for Theora. <br />
:: Even if there are other formats available that can do lossless. <br />
:: Not convinced about using another codec, a lossless mode for Theora is useful. <br />
:: Link to Theora todo page where lossless mode is requested: <br />

== Add link to "Reporting Abuse" page on the front page? ==<br />
<br />
There's been a bunch of spam recently, but I couldn't find any way to report abuse. I've added a skeleton page at [[Reporting abuse]], could we add a link to the front page?<br />
<br />
== Abuse == <br />
<br />
It's necessary to something about the excesive abuse of this Wiki, link approval is the minimal step for now. Also some additional barriers for registration should be considered. Also a stronger captcha, "3+4" isn't that efficient. [[User:DOS386|DOS386]] 12:44, 16 November 2009 (UTC)<br />
<br />
== Editing Theora? ==<br />
<br />
Is Theora considered an 'editible' format? Theora seems to be lossy - Is there a lossless, open format for video for use as a 'source' file type? There are a couple editors listed, but they seem pretty 'fringe' - anything more mainstream? If one wanted to create a 'video warehouse' that was 'pure' with respect to open formats, which file type/codec type would i use? 2009-12-25 15:55 [[User:BenTes]]<br />
<br />
:: > Theora seems to be lossy <br />
:: It '''is''' lossy <br />
:: > Is there a lossless, open format for video for use as a 'source' file type<br />
:: See above, HuffYUV, Lagarith, and Dirac <br />
:: > one wanted to create a 'video warehouse' that was 'pure' with <br />
:: > respect to open formats,<br />
:: :-)<br />
:: > which file type/codec type would i use?<br />
:: For final video, Theora. For intermediate files:<br />
:: * HuffYUV or Lagarith (can exist only inside AVI ??? but this could be changed)<br />
:: * YUV4MPEG (is 'pure' but not compressed)<br />
:: * Dirac in lossles mode (very slow)<br />

<hr />
<div>=== Speex over RTP ===<br />
<br />
While [[Ogg]] is the native file format for speex data, an RTP encapsulation is a natural fit with the codec's low latency design.<br />
<br />
Fortunately, unlike [[Vorbis]] and [[Theora]], [[Speex]] has no required setup headers, so the application is easy. A [http://speex.org/drafts/draft-herlein-speex-rtp-profile-02.txt draft exists]. It just needs to be reviewed and then taken through the formal ratification process with the IETF.<br />
<br />

This is the ToDo list for the theora project. If you're interested in helping out please try one of the ideas below, and coordinate with us on the [http://lists.xiph.org/mailman/listinfo/theora-dev mailing list] or [irc://freenode.net/theora irc].<br />
<br />

= libtheora reference implementation =<br />
<br />
== Theora 1.1 ==<br />
<br />
* Improve [http://svn.xiph.org/branches/theora-thusnelda/ theora-thusnelda] an make it the reference implementation: see [http://web.mit.edu/xiphmont/Public/theora/demo.html Theora "the push for 1.0" update] and [http://web.mit.edu/xiphmont/Public/theora/demo2.html Theora: The push for 1.0, Thusnelda project update 20080320]: xiphmont articles on theora future (actually, this will be in libtheora 1.1 not 1.0)<br />

<br />

<br />
= Application Support =<br />
<br />
* update binaries of [http://xiph.org/quicktime/ XiphQT] and [http://illiminable.com/ogg/ Directshow Filters] (includig fix for bug [https://trac.xiph.org/ticket/1301 1301])<br />
* update and fix FFMPEG2THEORA (see [https://trac.xiph.org/report/22 Trac])<br />
<br />
== Easy Transcoding on Windows ==<br />
<br />
It's difficult for some people to create theora files outside the command line. We need a simple tool that does drag-and-drop transcoding, with a gui for metadata and license marking, and some simple cleanup like crop/scale/rotate and color adjustment. This could be just a wrapper around ffmpeg2theora.<br />
<br />
Albeit technically it would be possible (and simple) to do GUI wrapper for ffmpeg2theora it may be wiser to write a completely new application which uses DirectShow to decode the given media file. This way the encoder wouldn't have to ship with evil patented decoders and still can transcode any source the computer can play in e.g. Windows Media Player. - [[User:Maikmerten|Maikmerten]] 12:06, 30 July 2007 (PDT)<br />
<br />
== Quicktime export ==<br />
<br />
It is important that content creators be able to easily create theora videos.<br />
<br />
* write a stand-alone output encoder plugin that does best-practices export<br />
* do a gui transcode tool, a little like ffmpeg2theora, but pulling from the native quicktime decoders and writing out theora + vorbis/speex. Must have a drag and drop interface with sensible quality presets, metadata insertion. Bonus points for integrated stream sourcing and [http://wiki.creativecommons.org/CcPublisher upload] to various free sharing sites with appropriate CC licensing.<br />
<br />
= Misc / publicity =<br />

Since many tens of millions of these units have been sold worldwide, there is a potentially huge, undocumented, base of portable media players which can play the Ogg Vorbis format. If you have one of these Chinese made players, just give it a try and see. [http://www.ebuyer.com/UK/product/126069 Here] is one cheap unbranded Chinese 1GB mp3 player that supports vorbis.</i><br><br><br />
<br />
<i>It is appropriate to say that in brazilian consumer market, there are unbranded MP3 players such as [http://produto.mercadolivre.com.br/MLB-71404870-mp3-player-2-gb-pen-drive-gravador-de-voz-radio-fm-_JM this one] that can flawlessly play Ogg Vorbis files. There are many of them branded as "Sony". I have tested one "Sony" and it does play Ogg Vorbis. If you have one of these players and know that they can play Ogg Vorbis, please inform which chipset these devices are equipped with. Many of these players can also be identified as having the following writings "MP3/WMA/FM/REC". All these are basically 1GB/2GB USB pen drives. </i><br />

:NOTE: The U3 and 7 both are buggy with Vorbis, in that they exhibit artifacts in the lower frequency range. As of firmware 1.29 on the U3, and 1.17 on the 7, both are broken. Cowon fixed this on the D2 about firmware 2.41 onward, and on the 7 with release 1.18 (29-MAY-2009). By way of a code examination, it appears the U5 does not suffer from this bug (On Cowon players that have the issue, there is a hex string which matches a low precision table. On the ones that do not have the issue, it has the correct normal precision value. This is referring to the Tremor decoder used). Most people describe this as a mild high pitched squeak. See this forum [http://www.cowonamerica.com/forums/showthread.php?t=13253 post] for more details. Some also say the iriver Clix 2 has this issue as well. Cowon on the D2 firmware page does not specifically mention that they fixed this issue.<br />
:The iAudio U2 is a small flash-based player (256MB/512MB/1GB) and supports Vorbis. Early U2 releases required a firmware upgrade for Vorbis support; as of September 2005 this support was included in the retail version. The iAudio G3 and iAudio 5 offer up to 2GB, and support Ogg Vorbis out-of-the-box. The G2 has storage from 256 MB up to 1 GB and supports the same formats. iAudio U3 is Cowon's last candy bar form factor flash-based player with a 5 way navigation control. It also supports FLAC and MPEG-4 video. All these players will talk to Linux or Mac (but the included software is Windows only. You'll need Windows for firmware updates.).<br />
:The G3, and most likely the other models as well, supports Ogg Vorbis from q0. Quality settings q-1 and q-2 (from the aoTuV ogg encoder) are not supported. It supports the meta tags ''album'' (limited length) and ''title''.<br />

USB 2.0 file transfer, Linux and Mac compatible (including firmware updates). Reading Ogg tags not supported (requires browsing music in 'files' mode rather than in 'tags' mode).<br />
:iAudio D2 comes in 4, 8 or 16GB capacities and can use SD and SDHC flash memory cards, supports music and movies supporting FLAC and Vorbis. USB 2.0 file transfer, Linux and Mac compatible (including firmware updates).<br />
:The ''iAudio U5'' is a player with 8 GB flash and USB (speed is at USB 1.0 level). The player is out of the box configurable as USB-mass-storage-device or MTP-device. It is available since early 2008. It supports Ogg Vorbis and FLAC since at least firmware 2.10. A firmware update is possible in mass-storage-mode, i.e. without additional proprietary software. The firmware is available at the US and Global site. The 2.10 firmware has multi language support, i.e. you can select for example english as language after flashing. Note however, that the FLAC/Vorbis firmware loses support for tag based browsing (as of version 3.16).<br />

:iRiver has a huge line of flash-based players with various memory sizes (128MB to 2GB). Some of these players may need an updated firmware in order to play Ogg Vorbis files, see the [http://www.iriveramerica.com/support/ support download page] for that. Note — on older players, only certain bitrates are supported, various problems are reported including reboots, silence and random noise when a VBR Vorbis passes outside the limit (either under 96Kbps or over 225 Kbps). Newer players don't have this limitation. However, please be alerted that many of the newer players, such as the Clix, use the Microsoft MTP transfer protocol exclusively so they only work with Windows, whereas other players may be shipped with MTP, but have alternate non-MTP firmware available for download. Tag support not present on U10/Clix (others also?), so Vorbis files will appear under 'unknown artist'/'unknown album'. Please note that the H10 model does not (yet?) support ogg, and can operate in both MTP and UMS (mass storage) modes. [http://easyh10.sf.net./ More information].

** The iRiver Clix 4GB ('''not''' the iRiver Clix gen 2) available at [[http://www.bhphotovideo.com/]] supports Ogg Vorbis audio and metadata (artist/album/song names). The following notes apply:<br />
*** The latest firmware, 2.6.0.0, was installed during the test. It is not known whether or not this is required for Ogg Vorbis support.<br />
*** Windows XP SP2 with Windows Media Player 11 (or later) is absolutely required. '''Windows Media Player 10 will not work.'''<br />
*** MTP is the only method to access the device. '''UMS will not work.'''<br />
*** Once Windows Media Player 11 has been installed, other programs such as Windows Explorer or Winamp can be used to load Vorbis songs normally.<br />

:The MP-130 is a portable player with flash memory in 128/256/512MB sizes. This appears to be a rebranded Iops player. The MP-400 is a tiny machine with lots of features (line in, mic, fm radio, usb 2.0). With the updated 4.1 firmware it supports Ogg Vorbis files encoded with libvorbis version 1.0rc2 or later. When trying to play files encoded with earlier versions it freezes on playback, requiring an USB connect or reset button pressed (through a tiny hole) to wake up again. The MP-120, a 1Gb flash player, supports Ogg Vorbis with a firmware upgrade since March 2005. MP-120 still doesn't play old Ogg Vorbis files, but they don't make it freeze up.

:Many Yepp players support Ogg, please see [[PortablePlayers/SamsungYepp]] for more details about each model. Note: many of these models being sold into DRM-sensitive markets (e.g. the United States) are configured as MTP (Media Transfer Protocol) devices rather than as USB mass-storage drives (UMS) and may require the use of specialized software on any system with which you use them. Samsung provides Windows drivers with these devices, which may or may not be necessary on Windows systems (recent versions of Windows Media Player reportedly support these devices without a specific driver). Using MTP-based players on non-Windows PCs will require installation of additional software. Linux support for at least some of these devices is available through [http://libmtp.sourceforge.net/ libmtp] and the "generic MTP device" plugin in [http://amarok.kde.org/ Amarok]. Read the specifications on the box carefully; if it says it depends on Windows Media Player, then it's probably an MTP device which may need Windows drivers or other MTP support software.<br />

The P2 also has FM radio and stereo bluetooth. In the U.S. it is likely that the device ships with MTP, but it is possible to switch it to UMS mode. Read through [http://www.anythingbutipod.com/forum/showthread.php?t=25784&highlight=samsung+games+pack this post/guide] (from anythingbutipod.com) for instructions.

<div>== Xiph.Org Application as a mentoring organization ==<br />
<br />
We need to apply for consideration as a mentoring organization 2008 March 3-12. Google lists the following questions in their [http://code.google.com/soc/2008/faqs.html#0.1_org_apply faq]. Our work-in-progress answers are inline.<br />
<br />
==== Describe your organization. ====<br />
<br />
The Xiph.Org Foundation is a 501(c)(3) non-profit organization dedicated to providing open and free-to-implement multimedia technology as a foundation for an interoperable, level playing field on the Internet and other digital distribution networks. Over the past 8 years we have developed most of the major patent-free and royalty-free audio and video codecs currently in use, including Vorbis, Speex, FLAC and Theora, as well as developing the Ogg streaming format, and the Icecast streaming media server. Xiph hosted libraries like liboggplay and liboggz power the underling html5 video support in Mozilla Firefox. <br />
<br />
This year we are also coordinating projects for the Annodex association under our umbrella. The Annodex projects develop standards and software for timed metadata and temporal media reference compatible with the existing web ecosystem. The Annodex streaming media server is used on sites such as wikipedia and archive.org to facilitate improved video seeking, inter-archive interoperability, and temporal media referencing via URLs<br />
<br />
==== Why is your organization applying to participate in GSoC 2008? What do you hope to gain by participating? ====<br />
<br />
We believe that the Xiph.Org Foundation has a wide-ranging set of projects that are both challenging and educational for students. Furthermore, they are important/useful goals for the wider technology community, and especially users of open source software.<br />
<br />
We believe that Xiph's mandate to develop multimedia standards and software is an important one, but as a small non-profit with no official staff we&mdash;of course&mdash;have limited resources. We hope that the results of GSoC will include the direct benefit of new software development, but also help grow the number of active participants in a long-term manner. Most of our core developers started as students, but have since moved on from their student days. Attracting and retaining students is essential to the health and sustainability of our project and is an important goal for all of us.<br />
<br />
==== Did your organization participate in past GSoCs? If so, please summarize your involvement and the successes and challenges of your participation. ====<br />
<br />
The Xiph.Org Foundation was invited to participate in GSoc in both 2006 and 2007, and informally mentored Annodex-related projects as well.<br />
<br />
In 2006, we were granted funding for 6 slots. One we weren't able to fill because our chosen students picked or were assigned to other projects. <br />
<br />
Two were [http://code.google.com/soc/xiph/about.html successful]. One, a [http://code.google.com/soc/xiph/appinfo.html?csaid=5F9265EEC6FA0611 hardware implementation of a Theora decoder]: this project produced HDL implementation of the major decoder components, to be used with a general purpose CPU, such as the open source LEON sparc implementation. Real time playback of SD content was demonstrated using these components in combination with the proprietary Nagios CPU design. Two, [http://code.google.com/soc/xiph/appinfo.html?csaid=213E2D30F095565D implementation of OggSkeleton support] in various tools. We have maintained contact with the two successful students since the program finished. One has continued to contribute code outside the GSoC term, continuing related work.<br />
<br />
The remaining three were unsuccessful through lack of necessary skills, health complications, insufficient motivation, or some combination of all of these.<br />
<br />
In 2007, we were given 2 project slots. One was an extension of the hardware decoder effort from last year. The other was helping to do R&D on Xiph's next-generation audio codec, Ghost. Both were marginally successful &mdash; the students reached the minimum goals set, but little more, and did not maintain contact with Xiph after the program. <br />
<br />
We enjoyed our participation over the last two years. It provided needed external input, energizing our project and improving our connections to the rest of the open source community. We think we've learnt a lot about how to mentor new and upcoming contributors, and how to best screen the applications we do receive.<br />
<br />
==== If your organization has not previously participated in GSoC, have you applied in the past? If so, for what year(s)? ====<br />
<br />
We have participated previously, in 2006 and 2007.<br />
<br />
==== Who will your organization administrator be? Please include Google Account information. ====<br />
<br />
Michael Smith has volunteered to be the primary admin this year. Google account mlrsmith@gmail.com.<br />
<br />
==== What license(s) does your project use? ====<br />
<br />
In general, we use the revised 3-clause BSD license for our libraries, to enable the widest possible uses of our formats and reference implementations.<br />
<br />
Our applications are generally GPL but LGPL or (GPL-compatible) modified. BSD is also acceptable.<br />
<br />
==== What is the URL for your ideas page? ====<br />
<br />
http://wiki.xiph.org/index.php/Summer_of_Code<br />
<br />
==== What is the main development mailing list or forum for your organization? ====<br />
<br />
We don't have a single central mailing list for all of the Foundation. Instead, we have project-specific mailing lists; of these the most active is vorbis-dev@xiph.org. A complete listing of our lists is available at:<br />
<br />
http://lists.xiph.org/mailman/listinfo/<br />
<br />
The primary contact of the Annodex projects is [http://lists.annodex.net/ annodex-dev@lists.annodex.net]<br />
<br />
==== What is the main IRC channel for your organization? ====<br />
<br />
Our main channel is #xiph on irc.freenode.net. We also have project-specific channels: #vorbis, #theora, #icecast, #speex and #annodex are the major ones.<br />
<br />
==== Does your organization have an application template you would like to see students use? If so, please provide it now. ====<br />
<br />
http://wiki.xiph.org/index.php/Summer_of_Code_Applications<br />
<br />
==== Who will be your backup organization administrator? Please include Google Account information. ====<br />
<br />
Ralph Giles will be the backup admin if no one else volunteers. Google account giles@xiph.org.<br />
<br />

<br />
==== What criteria did you use to select these individuals as mentors? Please be as specific as possible. ====<br />
<br />
We selected our mentors from the 'core' developers and contributors within Xiph. Mentors were selected based on how well they know the code area they're volunteering to mentor, how long they've been part of Xiph, how well they interact with others (particularly in terms of building community around our projects).<br />
<br />
The majority of the mentors we've selected are core developers on the various Xiph sub-projects that they've volunteered to mentor for. They have been contributing to the Xiph.Org Foundation for at least several years, and have shown a persistent interest both in the software we develop, and in helping to create a community around it. We have also made sure that each mentor has sufficient time available to adequately mentor their student(s).<br />
<br />
Michael Smith has been involved with the Xiph.Org Foundation and multimedia development since 2000 and remains one of our most involved core members. He helped write major portions of the vorbis-tools suite and the icecast streaming media server. He currently works as a developer at Fluendo.com on the GStreamer multimedia framework, flumotion (a streaming media server), and other multimedia software. <br />
<br />
Ralph Giles has been involved with the Xiph.Org Foundation and multimedia development since 2000. He has contributed to tool development and the Theora video codec. He handles much of the coordination and administrative work for the Xiph.Org Foundation. He mentored the successful "Hardware implementation of Theora decoding" project in GSoC 2006 and acted as an administrator.<br />
<br />
Silvia Pfeiffer is the founder of the Annodex project and president of the Annodex Association. She is the principle author of most of the Annodex specifications, RFC 3533 describing the Ogg media format, and is heavily involved as an organizer in both the Xiph and Annodex projects. Most recently she organized the [http://www.annodex.org/events/foms2007/ FOMS] developer summit and media recording for [http://lca2007.linux.org.au/ LCA 2007]. She helped mentor the successful "OggSkeleton support" project in GSoC 2006 and acted as an administrator during the application process.<br />
<br />
Christopher "Monty" Montgomery is the founder of the Xiph.Org Foundation, architect and lead developer of the Ogg Vorbis general purpose audio compression format. He has been doing open source development under the Xiph name since 1999. His current work focuses on development of a next-generation audio codec and a new Theora encoder. He helped mentor a project related to this in GSoC 2006.<br />
<br />
Timothy Terriberry is the author of the Theora video codec specification and the author of the theora-exp implementation. He has been an active contributor since 2003. He mentored a Theora-related project in GSoC 2006.<br />
<br />
Jean-Marc Valin is the architect and lead developer of the Speex voice codec. He has been involved in the Xiph.Org Founation since 2002. He mentored an audio codec research project in GSoC 2006.<br />
<br />
Arek Korbik is the author of the [http://xiph.org/quicktime/ Xiph QuickTime Components]. He has been a project contributor since 2005.<br />
<br />
Michael Dale is the author of the [http://metavid.org MetaVidWiki] project which implements many of the Annodex and Xiph technologies as an extension to MediaWiki.<br />
<br />
==== What is your plan for dealing with disappearing students? ====<br />
<br />
Our first goal will be to provide necessary support from the community such that our students do not want to suddenly vanish. We want our students to become real members of the community, with ongoing contributions. That said, we're well aware of the possibility of a student disappearing.<br />
<br />
We intend to be reasonably strict with requiring students to keep in touch - whilst we're quite happy for them to be absent for a while if they let us know in advance, we will intend to get at least twice-weekly updates from each student. <br />
<br />
The mentors will have primary responsibility for their students, but the admins (Mike Smith and Ralph Giles) are also going to ensure that the mentors are indeed keeping track of what their students are up to. We'll ask our students to provide means for us to get in touch beyond email, where possible - phone, etc - in case we need to get in touch urgently.<br />
<br />
==== What is your plan for dealing with disappearing mentors? ====<br />
<br />
Our mentors are all people who are major contributors to the Xiph projects - and have generally been contributing for many years. So, we think it's pretty unlikely that a mentor will disappear. However, we do have more mentors available than we expect to eventually have students (based on past years), so we're well able to take up the slack if a mentor becomes unavailable for any reason.<br />
<br />
Our admins will ensure that the mentors are keeping up with the students appropriately, and should it be absolutely necessary, we will either find another appropriate mentor, or the admins (Michael and Ralph) will take over mentoring the students directly.<br />
<br />
==== What steps will you take to encourage students to interact with your project's community before, during and after the program? ====<br />
<br />
The Xiph.Org Founation conducts much of its development discussion and community-building on our IRC channels. We'll ask that the students be present there while they're working, where adequate network access makes that possible. We hope to make them feel that they're an important part of our community; that their contributions are really making a difference towards the goals of Xiph. <br />
<br />
We intend to be open to their contributions - whilst we're aware that initially their work may not be of a quality sufficient to go into our core codebase immediately, we'll give them write access to our repository to work on a branch. We'll ask them to be open in discussing and designing their contributions on IRC and our mailing lists. Our application template welcomes them to come and ask us questions when they're trying to write up their application. We hope that some, or even all, of the students will continue to be part of the Xiph community after SoC concludes. For those students who have not previously contributed to open source software, we'll teach them about how important community building is for the ongoing health of such projects.<br />
<br />
==== What will you do to ensure that your accepted students stick with the project after GSoC concludes? ====<br />
<br />
We hope that the mentoring process and the experiences they have as part of GSoC will make the students interested in remaining part of Xiph, continuing development on the software they've been working on, and perhaps nurturing their patches towards inclusion in an actual release.<br />
<br />
A very important part of GSoC is for us to make them active members of the community, in particular on the irc channels and the mailing lists. Past experience tells that once they have become part of that community, they will stick around for longer.<br />
<br />
We will encourage them not to consider this just "a summer job", but as being part of a real community &mdash; and doing something that is both interesting, and useful to the wider world.</div>Saoshyanthttps://wiki.xiph.org/index.php?title=People&diff=10441People2009-07-17T12:22:50Z<p>Saoshyant: </p>

== Preliminary Agenda ==<br />
(2007-05 agenda items still to be addressed)<br />
* XSPF<br />
** move of XSPF validator of Sebastian Pipping to Motherfish (needs admin access for Python setup, or something like that)<br />
** making a priority to add default XSPF support on Icecast (there's a volunteer working on a XSLT for this; MikeS we would like your opinion)<br />
* theora<br />
** What about releasing 1.0alpha8 with current svn of theora-old, while completing the transition to the new complete decoder (which now is [http://lists.xiph.org/pipermail/theora-dev/2007-April/003220.html slower in many cases])? Current svn of theora-old has a faster decoder and an improved encoder wrt 1.0alpha7.<br />
* vorbis<br />
** [http://lists.xiph.org/pipermail/vorbis-dev/2007-May/018864.html development plan for vorbis encoder] (personal note: I do not think this is relevant yet--[[User:Saoshyant|Ivo]] 09:52, 15 May 2007 (PDT))<br />

At the request of various developers in europe we should alternate 24 and 12 GMT for meeting times.

<div>== Agenda ==<br />
<br />
* Address wiki spam ([[:Category:Spambots|Spambot]]s are now the most active "contributors")<br />
** Use norefer on links to make it less attractive? (default in [[Special:Version|newer]] MediaWiki)<br />
** More conter-measures? (e.g. delete accounts or auto-revert changes by identified spambots)<br />
** Or why not merely install a [[Wikipedia:CAPTCHA|CAPTCHA]] hack for MediaWiki (the software for this wiki)?<br />
<br />
* [[OggPCM_Draft1]], [[OggPCM_Draft2]] the whole process<br />
** The whole debate has exposed the fact that there is no decision making authority at the moment<br />
*** Some people have suggested creating a "steering committee" below the current board<br />
** Need a process to "approve" Xiph.Org codecs/standards<br />
** Some decision has to be made (in the shorter term) as to what version of OggPCM to adopt.<br />
** Should we define membership to Xiph.org? -- e.g. am I (jmspeex) a member?<br />
<br />
* The new [http://speex.org speex.org] site is ready, but someone (with permissions) needs to "install" it instead of the old one.<br />
<br />
* [[Vorbis]] stills need more support on portable players. Shouldn't a team of Public Relations cover this issue by contacting as many player producer companies as possible?<br />
<br />
* Annodex update on sw development and the [http://www.annodex.org/wiki/Main_Page Annodex Foundation]<br />

<div>{{draft}}<br />
<br />
This is an unimplented discussion draft about encapsulating srt subtitles in [[OggText]].<br />
<br />
Discussion is on the [http://lists.xiph.org/mailman/listinfo/accessibility accessibility@xiph.org] list.<br />
<br />
== SRT specification ==<br />
<br />
We adhere to existing SRT specifications without modification, for player compatibility.<br />
<br />
* We base this on: http://en.wikipedia.org/wiki/Subrip#Sample_file<br />
* Accordingly, it would make sense to be lenient regarding the index number and the display position.<br />
<br />
With considerations of web interoperability, we do NOT require support for the additional markup tags<br />
such as &lt;b&gt; and &lt;font&gt;<br />
described at: http://forum.doom9.org/showthread.php?p=470941#post470941<br />
<br />
== Encapsulation ==<br />
<br />
For details of Ogg BOS headers and granulepos etc, see [[OggText]]<br />
<br />
It should be simple:<br />
* It doesn't need an extra header.<br />
* Each time span is mapped into a single packet.<br />
* Silvia suggests to drop the index number upon mapping into Ogg -this will make it tolerant towards packet loss.<br />
* The time span and the text will thus be the data inside the page.<br />
<br />
[[Category:Ogg Mappings]]</div>Saoshyanthttps://wiki.xiph.org/index.php?title=OggText&diff=9631OggText2008-11-12T11:03:36Z<p>Saoshyant: cat</p>

<div>{{draft}}<br />
<br />
This page describes a generic media mapping (i.e. rules for multiplexing) of "text codecs" into Ogg.<br />
<br />
Text codecs are sequences of text chunks that have a timing relationship to an audio or video stream.<br />
<br />
Prominent examples of such text codecs are:<br />
* CC: closed captions (for the deaf)<br />
* SUB: subtitles<br />
* TAD: textual audio descriptions (for the blind)<br />
* KTV: karaoke<br />
* TIK: ticker text<br />
* AR: active regions<br />
* NB: metadata & semantic annotations<br />
* TRX: transcripts / scripts<br />
* LRC: lyrics<br />
* LIN: linguistic markup<br />
<br />
There are a multitude of existing open formats for specifying some of these - in particular for specifying closed captions and subtitles. They come in different complexities - some being simply a time stamp and a text, others providing for extensive styling, graphics, and motion of the text blocks over time.<br />
<br />
No matter what the differences - when multiplexing such codecs into Ogg, they all have to solve the same problems. This is why this page describes generically how to multiplex text codecs into Ogg.<br />
<br />
Codecs with existing mappings are:<br />
* CMML<br />
* Kate<br />
<br />
<br />
= Bitstream Format =<br />
<br />
Ogg codecs consist of a sequence of header packets and data packets.<br />
<br />
Header packets contain information necessary to identify and set up the codec.<br />
Data packets contain the actual codec data, in this case the time-aligned text.<br />
<br />
When these packets are multiplexed into Ogg, they are mapped to Ogg pages.<br />
For text codecs, there is a sequence of header pages, a sequence of data pages, and an EOS page, which finishes the stream. The pages have to be ordered non-decreasing with time. No data can come after the EOS page.<br />
<br />
<br />
== Header pages ==<br />
<br />
Header packets are a sequence of:<br />
* one ident header, which identifies the codec<br />
* one (optional) vorbis-comment header<br />
* one or more secondary header packets that are codec specific<br />
<br />
Any text codec has to map its header information into these header packets.<br />
<br />
Header packets must appear in order and all header packets must appear before any data packet. Each header packet is encapsulated in one Ogg page.<br />
<br />
<br />
=== The format of the ident header ===<br />
<br />
0 1 2 3 |<br />
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1| Byte<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| packtype | Identifier char[3]: 'txt' | 0-3<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| Identifier char[4]: codec identifier | 4-7<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| Version major | Version minor | 8-11<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
<br />
Each text codec page starts with a one byte type, just like this ident header. Similar to Kate, a type with the MSB set (eg, between 0x80 and 0xff) indicates a header packet, while a type with the MSB cleared (eg, between 0x00 and 0x7f) indicates a data packet. We use the packtype field in order to distinguish between the different header and data packet types.<br />
<br />
The following packtypes are distinguished:<br />
<br />
:headers:<br />
::0x80 ID header (BOS page) <br />
::0x81 vorbis-comment header (optional)<br />
::0x82-0xff secondary header pages of the codec in an order defined by the codec (optional)<br />
<br />
:data:<br />
::0x00 text data (including optional motions and overrides) <br />
::0x01 keepalive <br />
::0x7f end page (EOS page) <br />
<br />
As per the Ogg specification, granule positions of pages must be non decreasing within the stream. Header pages have granule position 0.<br />
<br />
In all header pages, the packtype is followed by the text codec magic from byte offset 1 to byte offset 3 ("txt"). The succeeding four bytes are to be used by the text codec to identify itself.<br />
<br />
For example, when CMML moves to using this generic text codec mapping approach rather than its own, the first eight bytes of the ident header will identify the track as a CMML codec track through a signature string of "\200txtCMML".<br />
<br />
Or as another example take a signature string of "\200txtsrt\0" which will identify srt being mapped.<br />
<br />
Version major & minor are fields that are used by the text codec to define the version of its mapping.<br />
<br />
=== The format of the Skeleton Fisbone ===<br />
<br />
Text codecs are required to be used in conjunction with [http://wiki.xiph.org/index.php/Ogg_Skeleton Ogg Skeleton].<br />
<br />
The following fields are defined in the Fisbone header for a text codec:<br />
* granulerate numerator & denominator<br />
* granuleshift<br />
* number of header pages/packets<br />
* Content-Type message header field, e.g. text/x-cmml, text/x-srt according to rfc2045<br />
** if no [http://www.iana.org/assignments/character-sets charset parameter] is given, it defaults to UTF-8<br />
** directionality of this text is implicitly given by the charset<br />
* Content-Language, e.g. en-AU, de-DE according to rfc4646 and http://www.iana.org/assignments/language-tags<br />
* Text-Type, e.g. CC, SUB, etc (see abbreviations as defined above)<br />
<br />
The default granule rate for text codecs is: 1/1000.<br />
<br />
<br />
== The granule position format ==<br />
<br />
Text codecs are discontinuous codecs. The data packets are placed into the Ogg stream at the time where the data starts. Their duration is given inside the data packet. Thus, when seeking to a specific time offset in a Ogg file that has a text codec, it can be quite difficult to determine what text data should still be on screen. <br />
<br />
The solution is to seek forward to the next text codec page, which then has information on the first text codec page that is still active. Then you can seek back to this page and seek forward to the previous page to gather all the pages that are still active.<br />
<br />
For this, the granulepos is being segmented into two parts, where one part signifies the insertion time of the current page, and the other part contains the granulepos of the first page with text codec data that is still active.<br />
<br />
+-----------------+-----------------+<br />
| granulepos prev | current time |<br />
+-----------------+-----------------+<br />
<br />
The size of this segmentation is stored in the 1 Byte integer granuleshift number of the Skeleton Fisbone. It describes how many of the lower bits to use for the partitioning. The upper bits then still signify a time-continuous granule position for a directly decodable and presentable data granule. The lower bits allow for specification of the granule position of a previous still active text codec page.<br />
<br />
The default granule shift used for text codecs is 32, which halfs the granule position to allow for the backwards pointer.<br />
<br />
== Data pages ==<br />
<br />
Data packets are generally the text data that is encapsulated into Ogg at a specific time.<br />
<br />
For text codecs, each data packet is mapped onto a single Ogg data page with all its content. This is possible because generally text codec packets are rather small. The insertion time is encoded in the granule_pos of the Ogg page.<br />
<br />
Since with text codecs we are talking about [http://www.xiph.org/ogg/doc/ogg-multiplex.html discontinuous codecs], there may be a long time between codec pages in a multiplexed stream. Therefore, optionally, the inclusion of keep-alive pages to be sent at regular intervals in the data stream is encouraged. This helps a decoder's seeking code to find a currently active text packet more easily.<br />
<br />
Thus, the following data pages can be distinguished:<br />
* ordinary data pages<br />
* keep-alive pages<br />
<br />
<br />
=== The format of a Data page ===<br />
<br />
0 1 2 3 |<br />
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1| Byte<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| packtype | filler / future use - 0 | 0-3<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| Start Time | 4-7<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| Start Time (continued) | 8-11<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| End Time | 12-15<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| End Time (continued) | 16-19<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| Codec Data ... | 20-...<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
<br />
<br />
The granulepos of a data page contains the start time encoded as a granule position in the higher bytes (see above).<br />
The lower bytes are used for seeking.<br />
<br />
Therefore, the duration that a data page is on screen is not encoded in the encapsulation format. In CMML, the duration was set by creating pages that would end previously active pages. Here, instead, we decide to encode the duration directly into the data page and make all such calculations from the data that is stored at the beginning of the data packet.<br />
<br />
In essence, we would only require to put the end time into the data page. However, for completeness, we add both, the start and the end time. Both are specified in seconds from the start of the video.<br />
<br />
After that, the data of the text codec will be encapsulated. This would preferrably be without a repetition of the start and end time. For example, for srt, it makes sense to include just the subtitle text as codec data.<br />
<br />
== EOS page ==<br />
<br />
The EOS page ends a text codec stream. It is an empty packet because all the information of the codec is encapsulated in the earlier data pages.<br />

<div>Mapping for embedding MIDI data streams in Ogg.<br />
<br />
This mapping was designed by Jack Moffitt. See [http://lists.xiph.org/pipermail/vorbis-dev/2001-August/004501.html this mailing list post] for documentation of his scheme.<br />
<br />
== Header packet ==<br />
<br />
OggMIDI streams have a single header packet for codec identification.<br />
<br />
0 1 2 3<br />
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1| Byte<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| Identifier 'OggMIDI\0' | 0-3<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| | 4-7<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| version number | time format | 8-11<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
| timebase | 12-13<br />
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+<br />
<br />
The header packet begins with the character sequence 'OggMIDI\0' for codec identification.<br />
<br />
This is followed by an 8 bit version field. The version must be 0 for the mapping described here.<br />
<br />
The time format field is also 8 bits, and describes the timestamp format used by the midi data. It is interpreted as follows:<br />
<br />
* 1 one beat per quarter note<br />
* 24, 25, 29, 30, (50, 59, 60?) corresponding smpte frame<br />
* other values are undefined<br />
<br />
The timebase occupies the final 16 bits and gives the number of ticks per time format unit.<br />
<br />
== Data packets ==<br />
<br />
The header packet is followed by a series of data packets, each of which contains an integral number of midi events.<br />
<br />
== Granulepos ==<br />
<br />
The granulepos field used for the Ogg page timestamps records microseconds since the beginning of the stream.<br />

<hr />
<div>== Vorbis over RTP ==<br />
<br />
This page documents current consensus on the RTP payload format for Vorbis audio. This encapsulation is useful for interactive and multicast streaming.<br />
<br />
=== Standard ===<br />
<br />
In 2008, the Vorbis RTP specification was accepted by the IETF's Network Working Group as RFC 5215. It may be found at<br />
*[http://tools.ietf.org/rfc/rfc5215.txt rfc5215.txt]<br />
*[http://xiph.org/vorbis/doc/rfc5215.xml rfc5215.xml]<br />
<br />
=== Issues ===<br />
<br />
Basically, we pack Vorbis packets into RTP packets; that's been part of the draft for some time. The hard part is achieving reliable header transmission, since RTP is usually used in combination with a no-guaranteed-delivery networking mechanism. Equally important, in multicast the headers can't be prepended on connection the way icecast does with HTTP streams.<br />
<br />
The current suggestion (due to Jack) is that we dispense with the chaining feature of Ogg streams, and only allow a single set of vorbis headers per RTP stream. Since RTP is most often used to stream live or at least individual events, this is not a serious limitation. Even in the "simulated live" case encoded files often have the same set of codebooks, and those that do not can be re-encoded on the fly.<br />
<br />
The only real drawback is the loss of a metadata update mechanism. This can be resolved either by using a completely separate metadata stream (which we've always wanted to do anyway) or by altering the spec to allow comment header packets to occur outside the headers. In the later case a recording application would need to insert chaining boundaries and duplicate headers at each metadata change. The former offers the client more control over the metadata stream bandwidth.<br />
<br />
=== Design ===<br />
<br />
* Vorbis packets get packed into RTP packets<br />
* Header parameters are fixed per stream, so they can be passed in the SDP<br />
* inline in the SDP?<br />
* HTTP reference or other protocol?<br />
* some kind of hash so clients can cache codebooks/parameters<br />
* inline in the RTP stream should also be allowed<br />
* Granulepos becomes timestamp (still in samples)<br />
<br />
=== Implementation ===<br />
<br />
Tor-Einar Jarnbjo has an [http://www.j-ogg.de/rtp/index.html example implementation] that extends the ideas in the kerr 03 draft a bit.<br />

[[Category:Vorbis]]</div>Saoshyanthttps://wiki.xiph.org/index.php?title=Spread_Open_Media/pt/It%27s_about_the_quality,_it%27s_about_the_freedom&diff=9469Spread Open Media/pt/It's about the quality, it's about the freedom2008-09-15T18:35:29Z<p>Saoshyant: Some corrections. Reviewed. Obrigado Rui.</p>
<hr />
<div>{{SOM_pt}}<br />
Portanto, aqui estamos. Formatos livres, média aberta. Bonitas palavras, mas o que é que elas significam para si? Talvez pouco ainda, mas continue a ler.<br />
<br />
Estas palavras significam vídeo de alta definição. Significam áudio de alta qualidade em ficheiros de tamanho reduzido. Significam documentos de escritório que funcionam em qualquer lado, independentemente do sistema. Significam listas de músicas ("playlists") que pode realmente partilhar. E, ainda mais importante, significam liberdade de qualquer restrição artificial imposta por corporações.<br />
<br />
Sim... corporações. Elas pretendem bloquear os seus ficheiros e respectivos conteúdos. Tente efectuar uma cópia de segurança de um DVD seu. Ah, pois é. Não consegue! É assim que muitas destas empresas mantêm o monopólio de software e respectivo domínio sobre o mercado de dispositivos móveis. À custa da liberdade dos seus clientes. A '''sua''' liberdade!<br />
<br />
Não preferiria dar o seu apoio a empresas que não lhe tirassem a sua liberdade? Mas, isso só pode acontecer se utilizar formatos livres. Deste modo as empresas são forçadas, pelo próprio mercado, a vender média aberta e dispositivos móveis ("players") que funcionem com formatos livres. Não gostaria de utilizar os seus ficheiros de multimédia onde quisesse? Talvez já tenha ouvido falar de DRM, mas isso é apenas a ponta do iceberg no que diz respeito aos formatos não livres.<br />
<br />
Uma grande preocupação é a de que um formato não livre, pertencente a uma empresa, não possa ser utilizado a não ser em produtos dessa mesma empresa, ou que esta exija que todos paguem uma licença pela utilização do dito formato. Por exemplo, quando compra um DVD está a pagar não só pelo já exageradamente caro conteúdo, mas também pela licença de o poder utilizar. Existe um exemplo caricato que aconteceu com a Xbox original. Apesar de ter um leitor de DVD tal como o produto da concorrência, contrariamente a esta, a Xbox não permitia visualizar filmes em DVD. A Microsoft evitou pagar essa licença forçando os seus consumidores a comprar um controle remoto caríssimo para cobrir os custos do dito licenciamento. Esta não é, claramente, a forma como uma empresa deve tratar os seus clientes. E é preferível nem começar a falar no formato MP3. Basta ver o que aconteceu com a Microsoft que teve de pagar uma indemnização de biliões à Alcatel-Lucent para que as pessoas pudessem continuar a utilizar um formato que soa como áudio VHS.<br />
<br />
Os formatos não-livres não têm valor para ninguém a não ser para quem detém a patente sobre eles. A liberdade de poder poupar dinheiro evitando pagar licenciamento desnecessário não pode ser encarada de animo leve.<br />
<br />
Ainda não está convencido? Os CD's áudio estão, sem grande dúvida, a ficar fora de moda com o virar do século, em parte provocado pelo próximo método de distribuição: lojas ''online'' para venda de música digital. Agora imagine o seguinte cenário: Temos um jovem empreendedor, sem grandes recursos financeiros, a tentar prestar um bom serviço representando artistas e ganhando uma comissão pelo seu trabalho. É apenas um intermediário. Mas, como ainda não enriqueceu, não consegue pagar as licenças necessárias para poder vender a sua música utilizando formatos não-livres, e ele sabe que não pode apenas vender ficheiros de música em formatos livres porque os seus clientes não irão saber como utilizar formatos livres, ou simplesmente não querem saber. Então, este jovem empreendedor, ou desiste do seu projecto de negócio ou continua, mas ilegalmente, e reza para que ninguém note.<br />
<br />
Você &mdash; sim você &mdash; pode evitar esta situação. Tudo o que tem de fazer é utilizar formatos livres, como Vorbis (.ogg) e FLAC para música, em vez de MP3 e outro formato qualquer que tentem promover como o seu sucessor. Utilize também Theora (.ogv) para vídeo.<br />
<br />
Ainda não está convencido? Ok, voltemos ao tema da liberdade. O conceito "Multimédia Aberta" representa duas coisa: liberdade de utilização do formato escolhido para qualquer fim (apenas possível quando se lida com formatos livres) e liberdade para utilizar o conteúdo para qualquer fim (apenas possível quando o conteúdo foi disponibilizado com uma licença livre). Para atingir o conceito de "Multimédia Aberta", uma espécie de Nirvana para alguns, uma ferramenta útil para outros, duas batalhas terão de ser travadas: Formatos livres e licenças livres. E "Multimédia Aberta" é apenas um passo no melhoramento da Humanidade.<br />
<br />
Será isto uma utopia irrealista? Não é. É sobre deixar um mundo melhor para a próxima geração.<br />
<br />
Mas é acerca de qualidade tal como é acerca de liberdade? Com certeza que sim.<br />
<br />
[http://hydrogenaudio.org/forums/index.php?showtopic=36465 Testes públicos] comprovam que Vorbis é superior ao MP3 e a outros formatos mais recentes como Musepack e AAC. Em qualquer tipo de música: clássica, Pop, Rock, etc. E suporta multi-canal! Os DJ's conhecem o poder do Vorbis e, graças à capacidade de "streaming" do formato Ogg, também os responsáveis das rádios ''online''.<br />
<br />
No que diz respeito à fala, nada é superior ao formato Speex. É poderoso, escalável e as pessoas utilizam-no em diferentes áreas como ''podcasts'', VoIP, livros áudio e robots com voz. Grave a sua voz nos formatos Speex e MP3 e compare a qualidade dos ficheiros criados, assim como o tamanho dos mesmos. A diferença é abismal. Não só o ficheiro Speex é muito menor, como soa muito melhor.<br />
<br />
Na área do áudio [http://en.wikipedia.org/wiki/Lossless_data_compression sem perda de qualidade], o formato FLAC é imbatível. Boa compressão, consumo reduzido de processador e &mdash; blasfémia! &mdash; funciona em dispositivos portáteis! É a opção favorita para arquivar música digitalmente. Os [http://livemetallica.com/ Metallica utilizam FLAC] e você também o deveria fazer.<br />
<br />
Quanto ao áudio, não há mais nada a dizer, mas e relativamente a vídeo? O futuro provavelmente trará o formato Dirac, mas para já existe o Theora. Nos seus primeiros anos, o Theora sofreu, devido a mau suporte nas aplicações existentes, o que criou a percepção de que o formato tinha pouca qualidade. Nada podia estar mais longe da verdade. O formato Theora [[Theora#Features|rivaliza com a maior parte dos formatos MPEG-4]], é igual a Xvid, e está pronto para disponibilizar ao mundo vídeo para todos, para os próximos cinco ou mais anos, até que algo melhor surja para o substituir. E isto utilizando apenas uma fracção dos recursos do CPU utilizada pelos seus rivais. A performance do formato Theora faz com que seja a escolha ideal para dispositivos com recursos mais modestos como o portátil XO do [http://laptop.org projecto OLPC] ou telemóveis. Isto atesta a qualidade deste formato.<br />
<br />
E se quiser partilhar vídeo ou áudio com os seus amigos? Para isso deve utilizar XSPF. É o único formato de ''playlist'' que parece ter acertado no alvo. A sério! Compare-o com outros. Não admira que aplicações multimédia como o VLC o estejam a utilizar internamente. É simples, é prático, faz tudo o que poderíamos precisar de uma ''playlist'' e mais.<br />
<br />
Até agora abordamos utilizações mais usuais, mas e os nichos de mercado? As coisas que apenas alguns utilizam? Como por exemplo, os designers gráficos. Até há relativamente pouco tempo, os designers gráficos eram forçados a utilizar formatos proprietários para trabalhar com gráficos vectoriais. Agora existe o formato SVG, compatível com navegadores web e programável por ''scripts''. Os designers podem utilizar este formato para desenhos simples ou aplicações complexas. Quão complexas? Por exemplo: misturando SVG, Theora e alguma programação por ''scripts'' consegue-se obter [http://bluishcoder.co.nz/video_svg_demo.ogg coisas destas]. Fantástico, não é?<br />
<br />
Os formatos existem, mas não podem tomar a decisão por si. É você quem precisa de decidir se quer utilizar formatos livres, ou não. Ajude a fazer do mundo um lugar melhor. Apoie a liberdade, apoie a qualidade. Utilize Média Aberta. Utilize formatos livres.</div>Saoshyanthttps://wiki.xiph.org/index.php?title=List_of_Theora_videos&diff=9466List of Theora videos2008-09-14T16:02:20Z<p>Saoshyant: </p>

<hr />
<div>This page is for collecting patches related to the MIME type and file extension changes outlined in [[MIME_Types_and_File_Extensions]].<br />
<br />
Please add links and information about your favorite applications to this page!<br />
<br />
== Standards ==<br />
<br />
[http://www.rfc-editor.org/rfc/rfc5334.txt RFC 5334] has registered video/ogg and audio/ogg, and redefined application/ogg.<br />
<br />
Please read the [http://www.iana.org/cgi-bin/mediatypes.pl IANA Application for Media Type] for details of the registration procedure.<br />
<br />
== Recommendations ==<br />
<br />
=== Players, File managers etc. ===<br />
<br />
Applications which read (decode) Ogg files should be extended to additionally recognize the file extensions .ogv, .oga, .ogx as outlined in [[MIME_Types_and_File_Extensions]].<br />
<br />
.ogg and .spx are kept for backwards compatibility for Vorbis and Speex respectively. Nevertheless, .oga should be considered an alternative extension by all programs.<br />
<br />
Programs that deal with media types, should recognize video/ogg, audio/ogg, and application/ogg. They should also be able to either recognize Skeleton, or at least be able to play files with a Skeleton stream without problems.<br />
<br />
=== Encoders ===<br />
<br />
Applications which create Ogg Theora files should be modified to default to the extension .ogv rather than .ogg.<br />
<br />
Applications which create Ogg Vorbis or Ogg Speex files should be modified to allow use of the extension .oga, but should continue to default to the extensions .ogg and .spx respectively. Ogg FLAC applications must be modified to support the .oga extension only.<br />
<br />
== Applications ==<br />
<br />
=== Players ===<br />
<br />
==== GStreamer ====<br />
<br />
A GStreamer hacker writes: ''gstreamer more or less doesn't need anything. There's one tiny thing that could be changed, but it's in API that nothing currently uses, so it doesn't matter.''<br />
<br />
==== MPlayer ====<br />
Mplayer successfuly plays .oga files such as those at [[XMLEmbedding]]. The mplayer<br />
Firefox plugin on Linux loads to play audio/ogg.<br />
<br />
==== VLC ====<br />
mime type associations have to be updated so VLC knows that it supports new extensions<br />
[https://trac.videolan.org/vlc/ticket/1279 VLC ticket]<br />
<br />
==== xine ====<br />
<br />
* xine ignores file extensions on loading, so it can already play files with the new extension .ogv.<br />
<br />
* xine implements a generic demuxer, so it can already play Ogg Audio (.oga) files containing additional bitstreams, ie. its Ogg Audio support is not limited to Ogg Vorbis I (Vorbis-only) files.<br />
<br />
* xine support for Ogg Skeleton bitstreams.<br />
<br />
Nevertheless, this<br />
[http://sourceforge.net/tracker/index.php?func=detail&aid=1726821&group_id=9655&atid=359655 PATCH] adds metadata for the new filename extensions and MIME types to xine's Ogg demuxer, which is useful in reporting xine-lib's capabilities.<br />
<br />
==== Songbird ====<br />
<br />
==== Amarok ====<br />
Amarok developer [http://bugs.kde.org/show_bug.cgi?id=149460 reports]: We get the list of supported filetypes from the engine, and the engine gets it from the backend (e.g. xinelib). Amarok itself doesn't distinguish between formats at all.<br />
<br />
==== XiphQT ====<br />
Arek released a new version, stating it does support the new MIME types and file extensions.<br />
<br />
==== FFMpeg ====<br />
FFMpeg is not able to play ogv files with Skeleton stream since it treated as a video stream with a higher importance than the Theora stream.<br />
<br />
:I have not seen this problem during my own tests. Going back to test ffmpeg.--Ivo<br />

==== Konqueror ====<br />
<br />
==== Nautilus ====<br />
Nautilus (and the whole of GNOME) uses the f.d.o shared-mime-info package.<br />

==== ffmpeg2theora ====<br />
<br />
Version 0.21 uses .ogv and Skeleton by default.<br />
<br />
==== VLC ====<br />
<br />
VLC also encodes to Ogg container. [https://trac.videolan.org/vlc/ticket/1412 Ticket] is open regarding the use of Skeleton. They welcome a patch.</div>Saoshyanthttps://wiki.xiph.org/index.php?title=Talk:List_of_Theora_videos&diff=9425Talk:List of Theora videos2008-09-03T17:06:50Z<p>Saoshyant: </p>

<div>Would like to add the following link to "See also", but only "category:Theora" is seen under the Edit. How to edit that template?<br />
http://en.wikipedia.org/wiki/Comparison_of_video_services<br />
<br />
:Go to [[Template:Theora]] and add [http://en.wikipedia.org/wiki/Comparison_of_video_services Comparison of video services]. Does this help? I'm not sure if it's an ideal link for the section but, being a wiki, new ideas are a must.--[[User:Saoshyant|Ivo]] 06:57, 2 August 2008 (PDT)<br />
::You are saying the link, to a comparison of video codecs, would not make a good addition to the informational wiki? I will hold off adding it, unless someone else thinks it is a good idea.<br />
:::Yeah, well. There's something you don't understand about the XiphWiki: it doesn't have enough users to be worth asking questions or opinions here. I'm pretty much the only person who checks what's going here frequently.<br />
:::The problem with adding that link to "See also", is that it would show up on EVERY single Theora-related page, which is not ideal since it's an external link and it's only useful for those who want to host videos. Which would be the people looking on this article, but not on the other articles. I suggest just putting the link somewhere in this article.--[[User:Saoshyant|Ivo]] 10:06, 3 September 2008 (PDT)<br />
<br />
Question: would it be a good idea to alphabatize this list, or put some sub-sections into it? Also, is it time to add a "streaming video" sub-section, since there are now two streams? --[[User:Matthewcraig|Matthew Craig]] 13:32, 27 August 2008 (EDT)<br />
:Well - I put in some sections and alphabetized the list. Hope everyone is happy with the new look. --[[User:Matthewcraig|Matthew Craig]] 12:02, 3 September 2008 (EDT)</div>Saoshyanthttps://wiki.xiph.org/index.php?title=MIME_Types_and_File_Extensions&diff=9381MIME Types and File Extensions2008-08-27T04:17:32Z<p>Saoshyant: </p>

<div>STATUS: Work on RFCs and tools is in process to reflect these policies. More details are [http://wiki.xiph.org/index.php/MIMETypesCodecs here], which also include a specification of the codecs parameter of the MIME tyes. Use the correct file extensions straight away.<br />
<br />
DISCLAIMER: currently, application/ogg, video/ogg, audio/ogg and audio/vorbis are registered MIME types. Registration for the others will be undertaken. During this process, the "x-" versions of these unregistered MIME types may be used.<br />
<br />
IMPLEMENTATION recommendations and patches: see [[MIME-Migration]].<br />
<br />
== .ogx - application/ogg ==<br />
<br />
* Ogg Multiplex Profile (anything in [[Ogg]])<br />
* can contain any logical bitstreams multiplexed together in an ogg container<br />
* will replace the .ogg extension from RFC 3534 http://www.ietf.org/rfc/rfc3534.txt<br />
* random multitrack files MUST contain a [[Skeleton]] track to identify all containing logical bitstreams<br />
* apps that identify a logical bitstream which they cannot decode SHOULD ignore it but MAY still decode the ones they can<br />
* thus, e.g. an annodex file can gracefully degrade to .ogx if an app cannot decode [[CMML]] and/or [[Skeleton]]<br />
* USE: application/ogg has been registered, so can be used immediately<br />
<br />
== .ogv - video/ogg ==<br />
<br />
* Ogg Video Profile (a/v in Ogg container)<br />
* apps supporting .oga, .ogv SHOULD support decoding from muxed Ogg streams<br />
* covers e.g. [[Theora]], Theora + Vorbis, Theora + Speex, Theora + FLAC, [[Dirac]] + Vorbis, [[OggMNG|MNG]] + FLAC, [[OggUVS]] inside Ogg<br />
* This list is not exhaustive (for example, [[Dirac]] + FLAC is acceptable too)<br />
* SHOULD contain a Skeleton track and/or MAY contain a CMML logical bitstream.<br />
<br />
== .oga - audio/ogg ==<br />
<br />
* Ogg Audio Profile (audio in Ogg container)<br />
* Applications supporting .oga, .ogv SHOULD support decoding from muxed Ogg streams<br />
* Covers Ogg [[FLAC]], [[Ghost]], and [[OggPCM]] <br />
* Although they share the same MIME type, Vorbis and Speex use different file extensions.<br />
* SHOULD contain a Skeleton logical bitstream.<br />
* Vorbis and Speex may use .oga, but it is not the prefered method of distributing these files because of backwards-compatibility issues.<br />
<br />
== .ogg - audio/ogg ==<br />
<br />
* Ogg Vorbis I Profile<br />
* .ogg applies now for Vorbis I files only<br />
* .ogg has more recently also been used for Ogg FLAC and for Theora, too &mdash; these uses are deprecated now in favor of .oga and .ogv respectively<br />
* has been defined in RFC 3534 http://www.ietf.org/rfc/rfc3534.txt for application/ogg, so rfc 3534 will be re-defined<br />
<br />
RATIONALE: .ogg has traditionally been used for Vorbis I files, in particular in HW players, hence it is kept for backwards-compatibility<br />
<br />
== .spx - audio/ogg ==<br />
<br />
* Ogg Speex Profile<br />
* .spx has traditionally been used for Speex files within Ogg and should be considered for backwards-compatibility<br />
<br />
== .flac - audio/flac ==<br />
<br />
* FLAC in native encapsulation format<br />
<br />
== .anx - application/annodex ==<br />
<br />
* Profile for multiplexed Ogg that includes a skeleton track and at least one CMML logical bitstream<br />
* apps that identify a logical bitstream which they cannot decode SHOULD ignore it but MAY still decode the ones they can<br />
* apps that come across an annodex file and cannot decode CMML and/or Skeleton, but can deal with the others SHOULD gracefully degrade by ignoring these<br />
<br />
== .axa - audio/annodex ==<br />
<br />
* Profile for audio in Annodex <br />
* covers e.g. [[Vorbis]], [[Speex]], [[FLAC]], [[Ghost]], [[OggPCM]] inside Ogg with Skeleton and CMML<br />
<br />
== .axv - video/annodex ==<br />
<br />
* Profile for video in Annodex <br />
* covers e.g. [[Theora]], Theora + Vorbis, Theora + Speex, Theora + FLAC, [[Dirac]] + Vorbis, [[OggMNG|MNG]] + FLAC, [[OggUVS]] inside Ogg with Skeleton and CMML<br />
<br />
== .xspf - application/xspf+xml ==<br />
<br />
* Profile for XSPF<br />
* Covers [[XSPF]], while being used through XML<br />
* Does not cover [[JSPF]], which is XSPF but on JSON<br />
<br />
== Codec MIME types ==<br />
<br />
Codecs need their own MIME types for streaming in RTP and to be used in multitrack ogg files using skeleton:<br />
<br />
* audio/vorbis for Vorbis without container<br />
* video/theora for Theora without container<br />
* audio/speex for Speex without container<br />
* audio/flac for FLAC without and in native container<br />
* text/cmml for CMML without container</div>Saoshyant
