libvpx library for the VP8 codec and WEBM container.

Other important changes are additions of decoders including, but not limited to,
Intel Indeo 5, WMA Pro, WMA Voice and HE-AAC.

See the Changelog file for a list of significant changes.

Please note that our policy on bug reports has not changed. We still only accept
bug reports against HEAD of the FFmpeg trunk repository. If you are experiencing
any issues with any formally released version of FFmpeg, please try a current
version of the development code to check if the issue still exists. If it does,
make your report against the development code following the usual bug reporting
guidelines.

<bjorn.e.lindgren@telia.com>).
- added mpeg demux (mpeg 1 and 2 compatible).
- added ASF demux.
- added prototype RM demux.
- added AC3 decoding (done with libac3 by Aaron Holtzman).
- added decoding codec parameter guessing (.e.g. for mpeg, because the
header does not include them).
- fixed header generation in mpeg1, AVI and ASF mux : wmplayer can now
play them (only tested video).
- fixed h263 white bug.
- fixed phase rounding in img resample filter.
- add mmx code for polyphase img resample filter.
- added CPU autodetect.
- added generic title/author/copyright/comment string handling (ASF and RM use them).
- added SWF demux to extract MP3 track (not usable yet because no MP3
decoder).
- added fractional frame rate support.
- codecs are no longer searched by read_header() (should fix ffserver
segfault).


version 0.4.3:

- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq@amsat.org>).
- fixed raw yuv output.
- added motion rounding support in MPEG4.

this +codec ;) (JuanJo).
- Halfpel motion estimation after mb type selection (JuanJo).
- added pgm and .Y.U.V output format.
- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
output.

<lists@reserv.at>, but changed completely since we use a format
instead of a protocol).

- added H263/MPEG4/MSMPEG4 decoding support. MPEG4 decoding support
(for openDIVX) is almost complete: 8x8 MVs and rounding are
missing. MSMPEG4 support is complete.
- added prototype MPEG1 decoder. Only I and P frames handled yet (it
can decode ffmpeg mpegs :-)).
- added libavcodec API documentation (see apiexample.c).
- fixed image polyphase bug (the bottom of some images could be
greenish).

(default=log). suppressed redundant -hq option.

AVI for example).

- suppressed master feature from ffserver (it should be done with an
external program which opens the .ffm url and writes it to another
ffserver).
- added preliminary support for video stream parsing (wav and avi half
done). Added proper support for audio/video file convertion in
ffmpeg.
- added preliminary support for video file sending from ffserver.

(see avio.h).
