From FOMS 2009

Main: CommunityGoals

Community Goals

The FOMS participants discussed key issues that open media systems are facing in the current environment:

1. Patent and legal issues around codecs
2. Ogg in Firefox: liboggplay
3. Authoring tools for open media codecs
4. Server Technology for open media
5. Time-aligned text and accessibility challenges
6. FFmpeg challenges
7. GStreamer challenges
8. Dirac challenges
9. Jack challenges
10. OpenMAX challenges

The following short-term goals were agreed on:

• Patents:
  • OpenMediaNow is the right container for this effort
  • Harass Mozilla, Google, Xiph, On2, BBC (and anyone else) to release any existing research and documentation they have
  • Look for and document expired patents in this area
  • Look for people who will put their names to this project
  • Get 10k$ for Groklaw, to get started
  • Get 50k$ mid-term to pay for work-time put into it
• Liboggplay:
  • We are not backporting/maintaining the liboggplay plugin for firefox 2.x
  • Need to focus on and improve seeking oggz_chop
  • Liboggplay needs Dirac support (get an experimental firefox build)
  • Better buffering with clips oggz_seek read ahead to give firefox duration and buffer info
• Authoring Tools:
  • Identify things that people do in professional production workflows, which parts are covered with open formats, which aren't
  • Also identify little processes that can be done in Ogg and create little videos, e.g. for Floss Manuals
  • Make Web video editing software also export Ogg Theora files, e.g. using pitivi
• Web Video Server:
  • We are deprecating mod_annodex in favor of oggz_chop in the long run
  • Need to focus on and improve seeking oggz_chop
  • Temporal URIs?: continue involvement with W3C? Timed Fragment group
  • Better Buffering with clips oggz_seek read ahead to give firefox duration and bufferinfo
• Timed Text:
  • Need support both for in-line and out-of-band time-aligned text and accessibility ata
  • Need example files for all use cases
  • Need to specify ways of rendering each of these
  • Implementations of OggText?, OggSRT?, and itext
• FFmpeg?:
  • Raise the release issue with the FFmpeg? community
  • Improve quality assurance processes
  • Mechanism to inform users about API changes
  • Make libavformat API more appropriate to users
• GStreamer:
  • Make more convenience/high-level methods and API
  • gst-launch-0.10 should be smarter
  • Remove the pain from audio/video conversion (colorspace, channels, etc..)
• Dirac:
  • Add Dirac support to Firefox through liboggplay
  • Add Dirac support to firefogg
  • Maybe integrate ffmpeg2theora and ffmpeg2dirac
  • Maybe create a libfisheye with Theora and Dirac similar to libfishsound, which will make integrations easier
• Jack/gstreamer
  • Add JACK transport sync gstreamer pipeline.
• Xiph OpenMAX IL components:
  • Choose an OpenMAX IL framework
  • Implement generic Ogg mux/demux components (instead of single Ogg Vorbis component)
  • Implement IL components for each codec (Theora, Dirac, Speex, CELT, FLAC)
  • Implement GStreamer OpenMAX plugins for each codec

The following long-term goals were agreed on:

• Convince Open Source developers that publicly documenting stuff is a good anti-patent strategy.
• In Liboggplay and in other Ogg tools, chaining support and playlists should be dealt with as basically the same
• Move Liboggplay from RGB to YUV rendering.. because there is hardware support for YUV
• Eventually, Ogg needs to become a file format that is too big to ignore
• Need unique time-aligned text language, e.g. TDHT and OggTDHT?
• Need specification for dynamic content selection and adaptation of video on the Web
