ffmpeg TODO list:
|
|
----------------
|
|
|
|
Fabrice's TODO list: (unordered)
|
|
-------------------
|
|
Short term:
|
|
|
|
- use AVFMTCTX_DISCARD_PKT in ffplay so that DV has a chance to work
|
|
- add RTSP regression test (both client and server)
|
|
- make ffserver allocate AVFormatContext
|
|
- clean up (incompatible change, for 0.5.0):
|
|
* AVStream -> AVComponent
|
|
* AVFormatContext -> AVInputStream/AVOutputStream
|
|
* suppress rate_emu from AVCodecContext
|
|
- add new float/integer audio filterting and conversion : suppress
|
|
CODEC_ID_PCM_xxc and use CODEC_ID_RAWAUDIO.
|
|
- fix telecine and frame rate conversion
|
|
|
|
Long term (ask me if you want to help):
|
|
|
|
- commit new imgconvert API and new PIX_FMT_xxx alpha formats
|
|
- commit new LGPL'ed float and integer-only AC3 decoder
|
|
- add WMA integer-only decoder
|
|
- add new MPEG4-AAC audio decoder (both integer-only and float version)
|
|
|
|
Michael's TODO list: (unordered) (if anyone wanna help with sth, just ask)
|
|
-------------------
|
|
- optimize H264 CABAC
|
|
- more optimizations
|
|
- simper rate control
|
|
|
|
Philip'a TODO list: (alphabetically ordered) (please help)
|
|
------------------
|
|
- Add a multi-ffm filetype so that feeds can be recorded into multiple files rather
|
|
than one big file.
|
|
- Authenticated users support -- where the authentication is in the URL
|
|
- Change ASF files so that the embedded timestamp in the frames is right rather
|
|
than being an offset from the start of the stream
|
|
- Make ffm files more resilient to changes in the codec structures so that you
|
|
can play old ffm files.
|
|
|
|
Baptiste's TODO list:
|
|
-----------------
|
|
- mov edit list support (AVEditList)
|
|
- YUV 10 bit per component support "2vuy"
|
|
- mxf muxer
|
|
- mpeg2 non linear quantizer
|
|
|
|
unassigned TODO: (unordered)
|
|
---------------
|
|
- use AVFrame for audio codecs too
|
|
- rework aviobuf.c buffering strategy and fix url_fskip
|
|
- generate optimal huffman tables for mjpeg encoding
|
|
- fix ffserver regression tests
|
|
- support xvids motion estimation
|
|
- support x264s motion estimation
|
|
- support x264s rate control
|
|
- SNOW: non translational motion compensation
|
|
- SNOW: more optimal quantization
|
|
- SNOW: 4x4 block support
|
|
- SNOW: 1/8 pel motion compensation support
|
|
- SNOW: iterative motion estimation based on subsampled images
|
|
- SNOW: try B frames and MCTF and see how their PSNR/bitrate/complexity behaves
|
|
- SNOW: try to use the wavelet transformed MC-ed reference frame as context for the entropy coder
|
|
- SNOW: think about/analyize how to make snow use multiple cpus/threads
|
|
- SNOW: finish spec
|
|
- FLAC: lossy encoding (viterbi and naive scalar quantization)
|
|
- libavfilter
|
|
- JPEG2000 decoder & encoder
|
|
- MPEG4 GMC encoding support
|
|
- macroblock based pixel format (better cache locality, somewhat complex, one paper claimed it faster for high res)
|
|
- regression tests for codecs which do not have an encoder (I+P-frame bitstream in svn)
|
|
- add support for using mplayers video filters to ffmpeg
|
|
- H264 encoder
|
|
- per MB ratecontrol (so VCD and such do work better)
|
|
- 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
|
|
- convert all the non SIMD asm into small asm vs. C testcases and submit them to the gcc devels so they can improve gcc
|
|
- generic audio mixing API
|
|
- extract PES packetizer from PS muxer and use it for new TS muxer
|
|
- implement automatic AVBistreamFilter activation
|
|
- make cabac encoder use bytestream (see http://trac.videolan.org/x264/changeset/?format=diff&new=651)
|
|
- merge imdct and windowing, the current code does considerable amounts of redundant work
