+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

-The OpenAL input device provides audio capture on all systems with a
-working OpenAL 1.1 implementation.
-
-To enable this input device during configuration, you need OpenAL
-headers and libraries installed on your system, and need to configure
-FFmpeg with @code{--enable-openal}.
-
-OpenAL headers and libraries should be provided as part of your OpenAL
-implementation, or as an additional download (an SDK). Depending on your
-installation you may need to specify additional flags via the
-@code{--extra-cflags} and @code{--extra-ldflags} for allowing the build
-system to locate the OpenAL headers and libraries.
-
-An incomplete list of OpenAL implementations follows:
-
-@table @strong
-@item Creative
-The official Windows implementation, providing hardware acceleration
-with supported devices and software fallback.
-See @url{http://openal.org/}.
-@item OpenAL Soft

-Solaris, and BSD operating systems.

-OpenAL is part of Core Audio, the official Mac OS X Audio interface.
-See @url{http://developer.apple.com/technologies/mac/audio-and-video.html}

-
-This device allows to capture from an audio input device handled
-through OpenAL.
-
-You need to specify the name of the device to capture in the provided
-filename. If the empty string is provided, the device will
-automatically select the default device. You can get the list of the
-supported devices by using the option @var{list_devices}.

-@subsection Options

-@item channels
-Set the number of channels in the captured audio. Only the values
-@option{1} (monaural) and @option{2} (stereo) are currently supported.
-Defaults to @option{2}.
-
-@item sample_size
-Set the sample size (in bits) of the captured audio. Only the values

-
-@item sample_rate
