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
