A temporary FFmpeg wish/todo list:


  • g723.1/rtp decoder (vivo g.723?)
  • g729/rtp decoder
  • Bethsoft VID decoder
  • a Monkey's Audio decoder, look at the c++ sdk sources
  • a JPEG2000 decoder
  • a gsm decoder
  • QCELP decoder spec is c.s0020 and source is c.r0020
  • AMV decoder, http://scrub50187.com/ has the creator. wikipedia has articles about the format also.
  • integer only vorbis decoder (to replace tremor)
  • LGPL'ed AAC decoder
  • Fix wmv8 decoder
  • MLP decoder




  • NSV muxer
  • add PAFF to H.264 decoder
  • improve seeking in asf files
  • clean up alac decoder
  • dts in wav support
  • raw dts support
  • integrate speex, glue code or native
  • add xing or vbri header parsing support to the mp3 decoder/parser
  • a aac parser so -acodec copy to mp4/mov works
  • clean up the h263 rtp patch found on this page: http://www.salyens.com/downloads/index.html#ffmpeg-0.4.7
  • add nice error messages to the flv demuxer(Nelly Moser) amr decoder and dv encoder/decoder
  • game formats:
  • subtitle support


  • multiple reference frames improvements
    • decide which frames to keep (e.g. long-term refs)
    • some changes to the mv prediction code
  • non translational motion compensation
    • estimate non translational parameters per block by using surrounding motion vectors
    • add a ac coded bit per block to switch between translational and non-translational MC
    • borrow the non translational MC code from libmpcodecs/vf_perspective.c
    • some changes to the encoder to decide between translational and non t.
  • Trellis quantization (select quantized coefficient so as to minimize the rate distrortion
  • 4x4 sized block support (we have 16x16 and 8x8 currently)
  • 1/8 pel motion compensation / estimation support (pretty much just encoder changes needed which in case of the iterative me should be trivial)
  • improve the intra color decision
