Fabrice's TODO list: (unordered)
5 c6fdc708 Fabrice Bellard
-------------------
6 a6aec9c9 Fabrice Bellard
Short term:
7
8
- use AVFMTCTX_DISCARD_PKT in ffplay so that DV has a chance to work
9 5ee03c86 Fabrice Bellard
- add RTSP regression test (both client and server)
10 a6aec9c9 Fabrice Bellard
- make ffserver allocate AVFormatContext
11 115329f1 Diego Biurrun
- clean up (incompatible change, for 0.5.0):
12 a6aec9c9 Fabrice Bellard
    * AVStream -> AVComponent
13
    * AVFormatContext -> AVInputStream/AVOutputStream
14 5ee03c86 Fabrice Bellard
    * suppress rate_emu from AVCodecContext
15 a6aec9c9 Fabrice Bellard
- add new float/integer audio filterting and conversion : suppress
16
  CODEC_ID_PCM_xxc and use CODEC_ID_RAWAUDIO.
17
- fix telecine and frame rate conversion
18
19
Long term (ask me if you want to help):
20
21 c6fdc708 Fabrice Bellard
- commit new imgconvert API and new PIX_FMT_xxx alpha formats
22
- commit new LGPL'ed float and integer-only AC3 decoder
23
- add WMA integer-only decoder
24
- add new MPEG4-AAC audio decoder (both integer-only and float version)

26 e5e65a53 Michael Niedermayer
Michael's TODO list: (unordered) (if anyone wanna help with sth, just ask)
27
-------------------
28 7ae93e6a Michael Niedermayer
- optimize H264 CABAC
29 e5e65a53 Michael Niedermayer
- more optimizations
30
- simper rate control
31 40d05a6b Fran├žois Revol
32 a960b45f Philip Gladstone
Philip'a TODO list: (alphabetically ordered) (please help)
33
------------------
34
- Add a multi-ffm filetype so that feeds can be recorded into multiple files rather
35 115329f1 Diego Biurrun
  than one big file.
36 a960b45f Philip Gladstone
- Authenticated users support -- where the authentication is in the URL
37
- Change ASF files so that the embedded timestamp in the frames is right rather
38
  than being an offset from the start of the stream
39
- Make ffm files more resilient to changes in the codec structures so that you
40
  can play old ffm files.

unassigned TODO: (unordered)
50 6fc18700 Michael Niedermayer
---------------
51 f44a2df0 Michael Niedermayer
- use AVFrame for audio codecs too
52 cfd06ceb Roman Shaposhnik
- rework aviobuf.c buffering strategy and fix url_fskip
53 cb906609 Michael Niedermayer
- generate optimal huffman tables for mjpeg encoding
54 7ae93e6a Michael Niedermayer
- fix ffserver regression tests
55 bb05edcf Michael Niedermayer
- support xvids motion estimation
56
- support x264s motion estimation
57
- support x264s rate control
58
- SNOW: non translational motion compensation
59
- SNOW: more optimal quantization
60
- SNOW: 4x4 block support
61
- SNOW: 1/8 pel motion compensation support
62
- SNOW: iterative motion estimation based on subsampled images
63 367b16cb Michael Niedermayer
- SNOW: try B frames and MCTF and see how their PSNR/bitrate/complexity behaves
64
- SNOW: try to use the wavelet transformed MC-ed reference frame as context for the entropy coder
65
- SNOW: think about/analyize how to make snow use multiple cpus/threads
66
- SNOW: finish spec
67 bb05edcf Michael Niedermayer
- FLAC: lossy encoding (viterbi and naive scalar quantization)
68
- libavfilter
69
- JPEG2000 decoder & encoder
70
- MPEG4 GMC encoding support
71
- macroblock based pixel format (better cache locality, somewhat complex, one paper claimed it faster for high res)
72 755bfeab Diego Biurrun
- regression tests for codecs which do not have an encoder (I+P-frame bitstream in svn)
73 5b01f9ce Michael Niedermayer
- add support for using mplayers video filters to ffmpeg
74 b8a2e120 Michael Niedermayer
- H264 encoder
75
- per MB ratecontrol (so VCD and such do work better)
76 864bc965 Michael Niedermayer
- write a script which iteratively changes all functions between always_inline and noinline and benchmarks the result to find the best set of inlined functions
77
- convert all the non SIMD asm into small asm vs. C testcases and submit them to the gcc devels so they can improve gcc
78 1821d48e Baptiste Coudurier
- generic audio mixing API
79
- extract PES packetizer from PS muxer and use it for new TS muxer
80
- implement automatic AVBistreamFilter activation
81 ee0981ac Michael Niedermayer
- make cabac encoder use bytestream (see http://trac.videolan.org/x264/changeset/?format=diff&new=651)
82 57639aa3 Michael Niedermayer
- merge imdct and windowing, the current code does considerable amounts of redundant work
