Projects/Formats

In an effort to bring open-source ideals to the world of multimedia The Xiph.org Foundation (XiphOrg) develops a multitude of amazing products.

Ogg: Media container. This is our native format and the recommeded container for Xiph codecs.
OggSkeleton: Skeleton information on all logical content bitstreams in Ogg

Compressed Codecs:
- Vorbis: Audio codec with a fixed point decoder
- Theora: Video codec
- FLAC: Free Lossless Audio Codec
- Speex: Speech codec
- OggMNG: A mapping for encapsulating the MNG animation format in Ogg
Uncompressed Codecs:
- Audio:
  - OggPCM: Uncompressed PCM audio, primarily as an interchange codec
  - Another PCM format: Uncompressed PCM audio, under active development
  - Humorous PCM format: Uncompressed PCM audio - and a lot more!
- Video:
  - OggRGB: Uncompressed RGB video, primarily as an interchange codec, under active development
  - OggYUV: Uncompressed YUV video, primarily as an interchange codec, under active development
  - OggUVS: Uncompressed RGB and YUV video, under active development as an alternative to OggRGB and OggYUV.
- Text & Hyperlinking:
  - OggWrit: Text phrase codec (e.g. subtitles), no application support yet
  - CMML: Continuous Media Markup Language, used for Annodex and subtitles (xine and gstreamer support)
Metadata Codecs:
- Metadata: Arbitrary metadata stream format (vapourware so far)

Want to hear Xiph in action? These projects are using our codecs, formats, or libraries.

VorbisStreams: Stations streaming with the Vorbis codec
Games that use Vorbis: Games using the Vorbis codec for music or sound effects
VorbisHardware: Hardware players using the Vorbis codec
TVersity Media Server: A UPNP/AV compliant media server that uses the Ogg Vorbis libraries to transcode audio files to the Ogg Vorbis format.
