Community Goals
The FOMS participants discussed key issues that open media systems are facing in the current environment:
- Patent FUD around open codecs
- RTP streaming for open codecs
- Video and audio metadata specifications
- Open web video technology
- Comprehensive open media software tools
- Cross-platform audio API for PCM audio capture and playback
- Next-generation container formats
The following short-term goals were agreed on:
- Patents: how to deal with patent FUD
- document, document, document - put everything on record
- essentially build up your own virtual "patent pool" through documents
- also publish why you think you're unencumbered
- build up a body of allies & supporters
- RTP/RTSP streaming:
- develop a specification of Dirac over RTP
- Metadata:
- many metadata formats exist, but we need to design metadata so it can be multiplexed into the binary media files
- Ogg recommendation for metadata and subtitles is CMML
- improve the design of CMML
- create a skeleton description format separate to CMML to describe dependencies between tracks
- Tool support:
- talk to people to find out what applications are required and prioritise them
- one low-hanging fruit is the development of ffmpeg2dirac based on ffmpeg2theora
- development of gui wrappers to ffmpeg2theora for major OSs
- development of a browser extension for ffmpeg2theora for hosting sites, such that the transcoding is done client-side
- Web video:
- encourage W3C to undertake a patent search and put out a call to patent holders to speak up now
- research javascript API inconsistencies and provide feedback to WHAT WG as input to the HTML5 standard
- encourage mv_embed adoption in CMSs
- PCM audio API:
- complete the design of libsydney
- finish first full implementation of libsydney
- Next-generation container formats:
- proposed improvements to Ogg need documentation
- extract bit packer out of libogg to avoid perception that Xiph codecs can only be used within Ogg
The following long-term goals were agreed on:
- Create implementations for Vorbis and Theora over RTP
- Extend open media tool support for transcoding, editing, hosting
- Work towards best practices to do platform-independent audio
