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.

Container Formats

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:
- OggPCM: Uncompressed PCM audio, primarily as an interchange codec (supported only by Arc)
- OggPCM2: Uncompressed PCM audio, favored by most Xiph developers (will be renamed to OggPCM2 at some point)
- OggRGB: Uncompressed RGB video, primarily as an interchange codec, undergoing heavy debate (supported only by Arc)
- OggYUV: Uncompressed YUV video, primarily as an interchange codec, undergoing heavy debate (supported only by Arc)
- OggUVS: Uncompressed RGB and YUV video, under active development as an alternative to OggRGB and OggYUV.
- OggWrit: Text phrase codec (e.g. subtitles), no known implementation
- CMML: Continuous Media Markup Language, foundation for Annodex, recommended format for subtitles.
Metadata Codecs:
- Metadata: Arbitrary metadata stream format (vapourware so far)
