Work In Progress

• General Usage:
  • Metadata: Various types of Ogg metadata including the M3F (Multimedia Metadata Format) and XMLEmbedding
  • MIME_Types_and_File_Extensions: MIME Types and file extensions for Ogg multimedia files
  • Subtle: Subtitling tool for professional use that intends to support most subtitle formats including CMML and OggKate
  • Text_Codecs_Ogg_Mapping: A generic media mapping for (discontinuous) text codecs into Ogg

• Compressed Codecs:
  • Theora 1.1 "thusnelda": improving compression efficiency while keeping compatibility, see Theora11Todo
  • OggDirac: The "next-generation" wavelet based video codec, lossy or lossless
  • OggCELT: A low-latency audio codec
  • OggMNG: A mapping for encapsulating the MNG animation format in Ogg

• Uncompressed Codecs:
  • OggKate: A codec for karaoke and text encapsulation in Ogg
  • OggPCM: New Uncompressed PCM audio, currently being implemented (formerly Draft2)
  • OggSpots: A mapping for encapsulating timed images in Ogg
  • OggUVS: Uncompressed RGB and YUV video, under active development (preferred to OggRGB and OggYUV).

• Abandonware (nobody working on those as far as we know)
  • Ghost: A "next-generation" audio codec (vapourware so far -- don't hold your breath)
  • Oggless: Embedding Xiph codecs like Vorbis in containers other than Ogg
  • IceShare: P2P content distribution
  • OggPCM_Draft1: Original uncompressed PCM audio proposal
  • OggRGB: Original uncompressed RGB video proposal
  • OggWrit: Text phrase codec (e.g. subtitles)
  • OggYUV: Original uncompressed YUV video proposal
