Willy on wheels: moved TheoraRTP to TheoraRTP on wheels

== Theora over RTP ==

This page maintains design consensus for the RTP payload format for Theora video. This is useful in interactive and multicast streaming.

=== Drafts ===

Current version of the draft is being written using the XML markup defined in [http://xml.resource.org/public/rfc/html/rfc2629.html RFC2629]. Text and XML versions of the current draft state are available here:
*[http://svn.xiph.org/trunk/theora/doc/draft-ietf-avt-rtp-theora-00.txt draft-ietf-avt-rtp-theora-00.txt]
*[http://svn.xiph.org/trunk/theora/doc/draft-ietf-avt-rtp-theora-00.xml draft-ietf-avt-rtp-theora-00.xml]

=== Issues ===

As with Vorbis, the issue is the decoder setup configuration carried in the bitstream headers which must be transmitted reliably.

We can probably just ignore the keyframe issue and let the client spin until it sees one.

=== Design ===

The issues are very similar to Vorbis, so we can probably copy that draft in some detail.

How should timestamps work? Frames like in [[Ogg]]? Real time? Some associated audio timebase?

Talk:Vorbis

2014-08-08T22:40:22Z

Willy on wheels: moved Talk:Vorbis to Talk:Vorbis on wheels

== Question ==

What about non-standard encoders and tunings?

Shouldn't you make a page about how to encode vorbis files?

[JohnRipley] How about a list of third party implementations of the Vorbis codec itself? For example: JOrbis, and mine :)

== Windows Media Player Encoding ==

[cparker] I'd like to know how to enable Windows Media Player to encode vorbis files directly from the "Rip" tab. I'm using Windows Media Player 9-10. I checked vorbis.com[http://vorbis.com], and it appears to be quite outdated. (It makes a reference to irc.xiph.org.)

== HW requirements ? ==

[xerces8] What CPU power (in terms of popular PC CPUs) is required for realtime decoding of Vorbis ?
Does tremor require more/less time/space as the "classic" version ?
(I plan to purchase a used laptop to use as a Vorbis playing station, so I need to know, thanks)

== RE: HW requirements ? ==

> What CPU power required for realtime decoding of Vorbis

Why don't you test ? 100 MHz Pentium 1 (just a guess)

> Does tremor require more/less time/space as the "classic" version ?

Space: same/irrelevant/unreproductable (???), time: probably slightly slower

== Merge proposal ==

Any reason for this:

* [[VorbisSoftwareEncoders]]: List of libvorbis frontends
* [[VorbisEncoders]]: List of encoders (e.g. Xiph, aoTuV, GT, vorbis-java)

Merge them ? [[User:DOS386|DOS386]] 15:21, 19 October 2007 (PDT)

Vorbis

2014-08-08T22:40:22Z

Willy on wheels: moved Vorbis to Vorbis on wheels

'''Vorbis''' is a patent-clear, fully open, general purpose audio encoding format standard that rivals or even surpasses the 'upcoming' generation of proprietary codecs ([[Wikipedia:Advanced Audio Coding|AAC]] and [[Wikipedia:TwinVQ|TwinVQ]], also known as VQF). There is no raw Vorbis stream defined, instead the Vorbis codec is typically used in the [[Ogg]] container format for audio files. Because for a long time the Ogg container was quasi exclusive for Vorbis people often refer to it as 'Ogg Vorbis'. Later the FLAC audio codec as well as the video codecs Theora and Dirac began to be used inside Ogg too. In 2010 the [[WebM]] format was defined using the Vorbis codec inside the WebM container.

libvorbis, a BSD-licensed source implementation of Vorbis as a library is available; See the [http://xiph.org/vorbis/ Ogg Vorbis page] for documentation, downloads and distribution terms.

Many hard- and software players support Ogg Vorbis; see [http://www.vorbis.com/ vorbis.com] or the links below for a list of all the players we know about.

Talk:Ogg

2014-08-08T22:39:57Z

Willy on wheels: moved Talk:Ogg to Talk:Ogg on wheels

== what about the '''.ogm''' format? ==
is it officially dead?

:The .ogm format is a hack of ogg.
::It will probably be replaced by .ogx and .ogv and .oga.

== what about the '''.mka''' and '''.mkv''' ([http:://www.matroska.org matroska]) format? ==
someone says that vorbis streams are smaller if contained in .mka files instead of .ogg files.

== Is it possible to limit the payload size using the current api? ==

There is only a maximum of about 64k now. In some cases, saying only 4096 bytes is maximum, it would be hoped that the libogg can provide such a ctl function to limit the maximum payload size in one ogg page.

Ogg

2014-08-08T22:39:57Z

Willy on wheels: moved Ogg to Ogg on wheels

The '''Ogg''' transport bitstream is designed to provide framing, error protection and seeking structure for higher-level codec streams that consist of raw, unencapsulated data packets, such as the [[Opus]], [[Vorbis]] and [[FLAC]] audio codecs or [[Theora]] and [[Dirac]] video codecs.

== Name ==

Ogg derives from "ogging", jargon from the computer game Netrek. Ogg is not an acronym and should not be mentioned as "OGG".

== Design constraints for Ogg bitstreams ==

* True streaming; we must not need to seek to build a 100% complete bitstream.
* Use no more than approximately 1-2% of bitstream bandwidth for packet boundary marking, high-level framing, sync and seeking.
* Specification of absolute position within the original sample stream.
* Simple mechanism to ease limited editing, such as a simplified concatenation mechanism.
* Detection of corruption, recapture after error and direct, random access to data at arbitrary positions in the bitstream.

== Specification / standard==

The Ogg transport bitstream and file format is defined in RFC 3533 approved 2003-May. As RFC documents are invariable once approved, there will never be newer versions of RFC 3533, but an [[RFC_3533_Errata]] exists instead. Existing flaws are discussed at [[OggIssues]], ideas for the future at [[TransOgg]].

== Detecting Ogg files and extracting information ==

Ogg files do begin with a signature "OggS", this signature also repeats many times inside the file, at the beginning of every page. There are several tools to get information about Ogg files:
* Ogginfo - part of Vorbis-Tools, supports Vorbis codec only (historical Ogg-vs-Vorbis issue), other codecs cause it to report garbage
* Opusinfo - part of Opus-Tools, supports only Opus codec well, only minimal Vorbis support
* Oggz ???
* MediaInfo [http://sourceforge.net/projects/mediainfo/ sf.net/projects/mediainfo] - provides information about media (and some other) files, supports many types, also Ogg with various codecs, generic audio and video information only, no Ogg-specific details

== Projects using Ogg ==

=== Codecs ===

* [[Opus]]
* [[CMML]]
* [[FLAC]] ([http://flac.sourceforge.net/ogg_mapping.html Ogg mapping])

== OGG batch encoding possible on windows system??? ==

Is there ANY way to create a batch encoding of uncompressed .MOV files on a windows system into .OGG video files?

Basically SUPER batches files that are damaged (green artifacts)
I´ve got clean examples out of VLC in single transcodings, but once I switch to batch encodings the stream breaks (as you probably already know)
ffmpeg with an WinFF GUI frontend does the same

--[[User:Dunkelzahn|Dunkelzahn]] 16:05, 27 September 2010 (UTC)

:You should try ffmpeg2theora from the command line. If you also install MinGW or Cygwin you can then use the bash shell like "for i in *.mov; do ffmpeg2theora -V 2000 $i; done". --[[User:Gmaxwell|Gmaxwell]] 16:07, 27 September 2010 (UTC)

Hey Gmaxwell,

thanks for the tip, I just set up a batch conversion and the first files are coming along quite nicely. No artefacts yet. I didn´t go the MingGQ/Cygwin path, opting instead for a .bat file that cycles through all the MOV files.

I´ll update tomorrow and give a short feedback on how it went

Cheers

--[[User:Dunkelzahn|Dunkelzahn]] 16:28, 27 September 2010 (UTC)

Ooookay,

it worked allright, but I still believe that this is not a professional user-friendly approach to batch processing OGG video files in a project-based enviroment. Anybody care to write a GUI-based OGG converter for Windows that allows batch processing and individual tweaking of Theora/Vorbis settings. I believe there are already enough command line/linux Theora applications out there ;)

Theora

2014-08-08T22:39:36Z

Willy on wheels: moved Theora to Theora on wheels

'''Theora''' is a video codec, based on the [[VP3]] codec donated by [[On2 Technologies]]. We've refined and extended it, giving it the same future scope for encoder improvement [[Vorbis]] has. See http://theora.org/ for more information.

== Features ==

Features available in the Theora format (and a comparison to VP3 and MPEG-4 ASP):

* 8x8 Type-II Discrete Cosine Transform
* block-based motion compensation
* free-form variable bit rates (VBR)
* adaptive in-loop deblocking applied to the edges of the coded blocks (not existing in MPEG-4 ASP)
* block sizes down to 8x8 (MPEG-4 ASP supports 8x8 only with 4MV)
* 384 8x8 custom quantization matrices: intra/inter, luma/chroma and even each quant (more than VP3 and MPEG-4 ASP/AVC)
* flexible entropy encoding (Theora supports 80 VLC tables selectable per-frame, MPEG-4 ASP has just one)
* 4:2:0, 4:2:2, and 4:4:4 chroma subsampling formats (VP3 and MPEG-4 ASP only support 4:2:0)
* 8 bits per pixel per color channel
* multiple reference frames (not possible in MPEG-4 ASP)
* pixel aspect ratio (eg for anamorphic signalling/playback)
* non-multiple of 16 picture sizes (as possible in ASP, but not in VP3)
* non-linear scaling of quants values (as done in MPEG-4 AVC)
* adaptive quantization down to the block level (as possible in MPEG-4 ASP/AVC, but not in VP3)
* intra frames (I-Frames in MPEG), inter frames (P-Frames), but no B-Frames (as supported in MPEG-4 ASP/AVC)
* HalfPixel Motion Search Precision (MPEG-4 ASP/AVC supports HalfPixel or QuarterPixel)
* technologies used already in Vorbis (decoder setup configuration, bitstream headers...) not available in VP3

== Status ==
* '''1.1.1''' is the latest stable release (2009-10-01).
* The bitstream format was frozen in 1.0 Alpha 3 on 2004-08-04: every file created with this encoder (and, of course, later encoders) will be playable by any compliant Theora decoder.
* The decoder in 1.0 Alpha 8 implemented all features of the [http://theora.org/doc/Theora.pdf Theora Format Specification]: every file created by any compliant Theora encoder will be playable by the decoder in 1.0 Alpha 8 (and, of course, later decoders).

XSPF

2014-08-08T22:39:24Z

Willy on wheels: moved XSPF to XSPF on wheels

'''XML Shareable Playlist Format''' ('''XSPF'''), pronounced "spiff", is a next-generation [http://en.wikipedia.org/wiki/playlist playlist] format for digital media such as songs in Vorbis or MP3 format. This wiki is for developers.

The mime type for XSPF playlists is <tt>application/xspf+xml</tt>.

Spec is at http://www.xspf.org/specs/
