A temporary FFmpeg wish/todo list:
Decoders
- 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.
Demuxers
- iff demuxer (with anim and sound decoding), xine has a decoder for it
- g723.1/rtp demuxer
- g729/rtp demuxer
- Bethsoft VID demuxer
- vivo demuxer, look at the mplayer vivo demuxer for reference
- a xmv demuxer, look at http://thread.gmane.org/gmane.comp.video.ffmpeg.devel/25207/focus=25224 and http://www.maxconsole.net/?mode=news&newsid=411 for hints; also look at http://sourceforge.net/tracker/index.php?func=detail&aid=1097094&group_id=53761&atid=471491 (should be a working demuxer/decoder)
- AMV demuxer, http://scrub50187.com/ has the creator. wikipedia has articles about the format also.
Features
- a new audio api
- radix-4 fft routines
- grabbing from video devices under windows, apply this vfw capture patch http://lists.mplayerhq.hu/pipermail/ffmpeg-user/2006-December/005607.html
- -[h|v]flip options for ffplay
- improved documentation (web,manpage)
Misc
- 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 ation
- 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
Snow
- 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
A/V Filters
- adopt mplayer filter system or create new one.
- http://article.gmane.org/gmane.comp.video.ffmpeg.devel/39130
- for michaelni's idea of what to do
- http://article.gmane.org/gmane.comp.video.ffmpeg.devel/39130
- decide on name.
- libavfilter (conflicts with LAVF)? libavmunge?
