Improve RTSP/RTP layer: Difference between revisions

Revision as of 05:50, 8 June 2010

Roadmap/checklist for Josh Allmann's Summer of Code Project:

Primary goal: improve the receiver compatibility
- Add support for more widespread formats ([list will follow check gst live555 and feng])
  - X-Qt/quicktime depacketizer (see X-QT patch)
  - SVQ3 [1] and QDM2 [2] depacketizers
  - VP8 (see https://groups.google.com/a/webmproject.org/group/webm-discuss/browse_thread/thread/550f946b0e22ead2# )
- support Quicktime http tunnel mode
  - Initial implementation done and committed, not supported in the RTSP muxer yet
- untangle the AAC and mpeg4 format specific code from rtsp.c, make them proper dynamic payload handlers
- add RTP packetizers for codecs that we already have depacketizers for (Theora, Vorbis, any other?)
- support RTCP/Bye as end-of-file (see small task)
Secondary goal: improve application integration
- Provide an API to expose the rtcp layer (and the equivalent in RDT dialect)
- Try to support subtitle streams (either as rtcp-xr or application/text stream)
- Make VideoLanClient, MPlayer or Xine use FFmpeg RTSP
- Implement protocol variations (e.g. DCCP or improve SCTP)

Mentor: Luca Barbato, Martin Storsjö, Ronald S. Bultje
