-version 0.4.4:
-
-- fixed some std header definitions (Bjorn Lindgren
- <bjorn.e.lindgren at telia.com>).
-- added MPEG demuxer (MPEG-1 and 2 compatible).
-- added ASF demuxer
-- added prototype RM demuxer
-- 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 MPEG-1, AVI and ASF muxer: wmplayer can now
- play them (only tested video)
-- fixed H.263 white bug
-- fixed phase rounding in img resample filter
-- add MMX code for polyphase img resample filter
-- added CPU autodetection
-- 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 at amsat.org>)
-- fixed raw yuv output
-- added motion rounding support in MPEG-4
-- fixed motion bug rounding in MSMPEG4
-- added B-frame handling in video core
-- added full MPEG-1 decoding support
-- added partial (frame only) MPEG-2 support
-- changed the FOURCC code for H.263 to "U263" to be able to see the
- +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
- 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.
-- added pgmpipe I/O format (original patch from Martin Aumueller
- <lists at reserv.at>, but changed completely since we use a format
- instead of a protocol)
-
-
-version 0.4.2:
-
-- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
- (for OpenDivX) is almost complete: 8x8 MVs and rounding are
- missing. MSMPEG4 support is complete.
-- added prototype MPEG-1 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)
-- added support for non clipped motion vectors (decoding only)
- and image sizes non-multiple of 16
-- added support for AC prediction (decoding only)
-- added file overwrite confirmation (can be disabled with -y)
-- added custom size picture to H.263 using H.263+ (Juanjo)
-
-
-version 0.4.1:
-
-- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
- of AVI and ASF to DIV3.
-- added -me option to set motion estimation method
- (default=log). suppressed redundant -hq option.
-- added options -acodec and -vcodec to force a given codec (useful for
- AVI for example)
-- fixed -an option
-- improved dct_quantize speed
-- factorized some motion estimation code
-
-
-version 0.4.0:
-
-- removing grab code from ffserver and moved it to ffmpeg. Added
- multistream support to ffmpeg.
-- added timeshifting support for live feeds (option ?date=xxx in the
- URL)
-- added high quality image resize code with polyphase filter (need
- mmx/see optimization). Enable multiple image size support in ffserver.
-- added multi live feed support in ffserver
-- 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 conversion in
- ffmpeg.
-- added preliminary support for video file sending from ffserver
-- redesigning I/O subsystem: now using URL based input and output
- (see avio.h)
-- added WAV format support
-- added "tty user interface" to ffmpeg to stop grabbing gracefully
-- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
- (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
-- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
-- added new motion estimation algorithms, log and phods (Juanjo)
-- changed directories: libav for format handling, libavcodec for
- codecs
-
-
-version 0.3.4:
-
-- added stereo in MPEG audio encoder
-
-
-version 0.3.3:
-
-- added 'high quality' mode which use motion vectors. It can be used in
- real time at low resolution.
-- fixed rounding problems which caused quality problems at high
- bitrates and large GOP size
-
-
-version 0.3.2: small fixes
-
-- ASF fixes
-- put_seek bug fix
-
-
-version 0.3.1: added avi/divx support
-
-- added AVI support
-- added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
-- added sound for flash format (not tested)
-
