6Short term:
7
a6aec9c9 8- use AVFMTCTX_DISCARD_PKT in ffplay so that DV has a chance to work
5ee03c86 9- add RTSP regression test (both client and server)
a6aec9c9 10- make ffserver allocate AVFormatContext
115329f1 11- clean up (incompatible change, for 0.5.0):
a6aec9c9
FB
12 * AVStream -> AVComponent
13 * AVFormatContext -> AVInputStream/AVOutputStream
5ee03c86 14 * suppress rate_emu from AVCodecContext

15- 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
19Long term (ask me if you want to help):

22- commit new LGPL'ed float and integer-only AC3 decoder
23- add WMA integer-only decoder
c6fdc708 24- add new MPEG4-AAC audio decoder (both integer-only and float version)

26Michael's TODO list: (unordered) (if anyone wanna help with sth, just ask)
27-------------------
7ae93e6a 28- optimize H264 CABAC
e5e65a53 29- more optimizations
e5e65a53 30- simper rate control

32Philip'a TODO list: (alphabetically ordered) (please help)
33------------------
34- Add a multi-ffm filetype so that feeds can be recorded into multiple files rather
115329f1 35 than one big file.

36- 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.

6fc18700 50---------------
f44a2df0 51- use AVFrame for audio codecs too
cfd06ceb 52- rework aviobuf.c buffering strategy and fix url_fskip
cb906609 53- generate optimal huffman tables for mjpeg encoding
7ae93e6a 54- fix ffserver regression tests

55- 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
367b16cb
MN
63- 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- 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)
755bfeab 72- regression tests for codecs which do not have an encoder (I+P-frame bitstream in svn)
5b01f9ce 73- add support for using mplayers video filters to ffmpeg
b8a2e120

74- H264 encoder
75- per MB ratecontrol (so VCD and such do work better)
864bc965 76- 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
864bc965 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
1821d48e
BC
78- generic audio mixing API
79- extract PES packetizer from PS muxer and use it for new TS muxer
80- implement automatic AVBistreamFilter activation
ee0981ac 81- make cabac encoder use bytestream (see http://trac.videolan.org/x264/changeset/?format=diff&new=651)
57639aa3 82- merge imdct and windowing, the current code does considerable amounts of redundant work
