[libav.git] / doc / TODO
1 ffmpeg TODO list:
2 ----------------
3
4 Fabrice's TODO list: (unordered)
5 -------------------
6 Short term:
7
8 - seeking API and example in ffplay
9 - use AVFMTCTX_DISCARD_PKT in ffplay so that DV has a chance to work
10 - add RTSP regression test (both client and server)
11 - make ffserver allocate AVFormatContext
12 - clean up (incompatible change, for 0.5.0):
13 * AVStream -> AVComponent
14 * AVFormatContext -> AVInputStream/AVOutputStream
15 * suppress rate_emu from AVCodecContext
16 - add new float/integer audio filterting and conversion : suppress
17 CODEC_ID_PCM_xxc and use CODEC_ID_RAWAUDIO.
18 - fix telecine and frame rate conversion
19
20 Long term (ask me if you want to help):
21
22 - commit new imgconvert API and new PIX_FMT_xxx alpha formats
23 - commit new LGPL'ed float and integer-only AC3 decoder
24 - add WMA integer-only decoder
25 - add new MPEG4-AAC audio decoder (both integer-only and float version)
26
27 Michael's TODO list: (unordered) (if anyone wanna help with sth, just ask)
28 -------------------
29 - finish implementation of WMV2 j-picture
30 - H264 encoder
31 - optimize H264 CABAC
32 - per MB ratecontrol (so VCD and such do work better)
33 - more optimizations
34 - simper rate control
35 - reverse engeneer RV30/RV40
36
37 Francois' TODO list: (unordered, without any timeframe)
38 -------------------
39 - test MACE decoder against the openquicktime one as suggested by A'rpi
40 - BeOS audio input grabbing backend
41 - BeOS video input grabbing backend
42 - have a REAL BeOS errno fix (return MKERROR(EXXX);), not a hack
43 - publish my BeOS libposix on BeBits so I can officially support ffserver :)
44 - check the whole code for thread-safety (global and init stuff)
45
46 Philip'a TODO list: (alphabetically ordered) (please help)
47 ------------------
48 - Add a multi-ffm filetype so that feeds can be recorded into multiple files rather
49 than one big file.
50 - Authenticated users support -- where the authentication is in the URL
51 - Change ASF files so that the embedded timestamp in the frames is right rather
52 than being an offset from the start of the stream
53 - Make ffm files more resilient to changes in the codec structures so that you
54 can play old ffm files.
55
56 unassigned TODO: (unordered)
57 ---------------
58 - use AVFrame for audio codecs too
59 - rework aviobuf.c buffering strategy and fix url_fskip
60 - generate optimal huffman tables for mjpeg encoding
61 - fix ffserver regression tests
62 - support xvids motion estimation
63 - support x264s motion estimation
64 - support x264s rate control
65 - SNOW: non translational motion compensation
66 - SNOW: more optimal quantization
67 - SNOW: 4x4 block support
68 - SNOW: 1/8 pel motion compensation support
69 - SNOW: iterative motion estimation based on subsampled images
70 - FLAC: lossy encoding (viterbi and naive scalar quantization)
71 - libavfilter
72 - JPEG2000 decoder & encoder
73 - MPEG4 GMC encoding support
74 - macroblock based pixel format (better cache locality, somewhat complex, one paper claimed it faster for high res)
75 - finish NUT implementation
76 - movenc.c fix stts so that variable framerate files work
77 - seeking regression test
78 - regression tests for codecs which dont have an encoder (I+P frame bitstream in svn)
