-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 the 'master' branch)
-- 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
