<p>KikoV: /* Introduction */</p> <hr /> <div>== Integrating OGG into MacOsX ==<br /> <br /> Warning: this project is in study/design stage.<br /> <br /> === Introduction ===<br /> This project consists on integrating the Ogg Format and Vorbis Codec into MacOsX. That will result on having that in every sound application.<br /> <br /> The work consists on two main parts.<br /> * The Audio File Format should be recognised<br /> * The Sound should be coded/decodec.<br /> <br /> To do such tasks, new Core Audio API will be used.<br /> <br /> The former part would consist on the creation of an [http://developer.apple.com/documentation/MusicAudio/Reference/CAAudioTooboxRef/AudioFileComponent/CompositePage.html AudioFileComponent]. That component has to implement the AudioFileComponentBase AudioFileFormat and AudiofileObject clases. The examples on CoreAudio/AudioFile is a good starting point. It implements a rawAudio file reader/writer. The OGG part of ogg-vorbis should go here. The streaming support go here too.<br /> <br /> The second part is the codec support. To support Vorbis, the creation of a [http://developer.apple.com/documentation/MusicAudio/Reference/CoreAudio/audiocodec/chapter_3_section_1.html#//apple_ref/doc/uid/TP30001108-CH204 AudioCodec] is needed. The example on CoreAudio/AudioCodecs is a good starting point too. It implements a IMA4 codec. No file format are implied here. So, it should be a glue ( that I hasn't discovered yet ) from AudioFileComponent API to know that contained data is Vorbis and launching the CodecComponent.<br /> <br /> <br /> Finally, for the rest of Ogg Codecs, just the second part is needed. <br /> <br /> Work in progress...</div>

<p>KikoV: /* Projects/Formats */</p> <hr /> <div>= Projects/Formats =<br /> <br /> In an effort to bring open-source ideals to the world of multimedia The Xiph.org Foundation ([[XiphOrg]]) develops a multitude of amazing products. <br /> <br /> == Container Formats ==<br /> <br /> * [[Ogg]]: Media container. This is our native format and the recommeded container for Xiph codecs.<br /> * [[OggSkeleton]]: Skeleton information on all logical content bitstreams in Ogg<br /> <br /> * [[SpeexRTP]]: RTP payload format for voice<br /> * [[VorbisRTP]]: RTP payload format for general audio<br /> * [[TheoraRTP]]: RTP payload format for video<br /> <br /> == Codecs ==<br /> <br /> * [[Vorbis]]: Audio codec<br /> * [[Tremor]]: Fixed-point decoder<br /> * [[Theora]]: Video codec<br /> * [[FLAC]]: Free Lossless Audio Codec<br /> * [[Speex]]: Speech codec<br /> * [[Ogg Writ]]: Text phrase codec (e.g. subtitles)<br /> * [[Metadata]]: Arbitrary metadata stream format (vapourware so far)<br /> * [[OggMNG]]: A mapping for encapsulating the MNG animation format in Ogg<br /> <br /> == Software for distributing media ==<br /> <br /> * [[Icecast]]: Streaming server<br /> * [[Ices]]: Source client for Icecast servers<br /> * [[IceShare]]: P2P content distribution<br /> <br /> == Other software ==<br /> <br /> * [[OggComponent/VorbisComponent]]: Wrappers to integrate Ogg-Vorbis into MacOsX<br /> <br /> = Demonstrations =<br /> <br /> Want to hear Xiph in action? These projects are using our codecs, formats, or libraries.<br /> <br /> * [[VorbisStreams]]: Stations streaming with the Vorbis codec<br /> * [[Games that use Vorbis]]: Games using the Vorbis codec for music or sound effects<br /> * [[VorbisHardware]]: Hardware players using the Vorbis codec<br /> * [http://www.tversity.com TVersity Media Server]: A UPNP/AV compliant media server that uses the Ogg Vorbis libraries to transcode audio files to the Ogg Vorbis format.<br /> <br /> = Project management =<br /> <br /> * [[MonthlyMeeting]]<br /> * [[MailingLists]]<br /> * [[Bounties]]<br /> * [[HyperFish]]<br /> <br /> = Wiki internal =<br /> * [[Sandbox]]: Testbed for testing editing skills.<br /> * [[Translations]]: What about some translation work</div>
