A temporary FFmpeg wish/todo list:
- implement a new audio api
- implement seeking in flv files
- improve seeking in asf files
- improve flv demuxer, print name of missing codec support
- improved documentation (web,manpage)
- improve ac3 encoder (implement block switching)
- implement radix-4 fft routines
- implement iff demuxer (with anim and sound decoding), xine has a decoder for it
- clean up alac decoder
- implement dts in wav support
- implement raw dts support
- implement Bethsoft VID demuxer/decoder
- implement grabbing from video devices under windows
- implement a Monkey's Audio decoder, look at the c++ sdk sources
- implement a JPEG2000 decoder
- integrate speex, glue code or native implementation
- implement -[h|v]flip options for ffplay
- implement vivo demuxer, look at the mplayer vivo demuxer for reference
- implement 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
- implement a gsm decoder
- add xing or vbri header parsing support to the mp3 decoder/parser
- implement a aac parser so -acodec copy to mp4/mov works
- implement a flash screen video encoder (do a fixed 16x16 block and bruteforce block encoder)
- implement tiff/tga in mov support, look at openquicktime for reference
- implement QCELP decoder spec is c.s0020 and source is c.r0020
- 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, amr decoder and dv encoder/decoder
- game formats:
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
