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])
    • support Quicktime http tunnel mode
      • Initial implementation done and committed, not supported in the RTSP muxer yet, missing handling of the x-server-ip-address header
    • untangle the AAC and mpeg4 format specific code from rtsp.c, make them proper dynamic payload handlers
      • Committed
    • factorize out common code for parsing SDP (fmtp) lines, that is duplicated in parse_h264_sdp_line, amr_parse_sdp_line and xiph_parse_sdp_line
    • 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
      • Patch submitted to VLC, awaiting review
    • Implement protocol variations (e.g. DCCP or improve SCTP)
