7 - Flash Screen Video 2 decoder
8 - ffplay/ffprobe/ffserver renamed to avplay/avprobe/avserver
9 - ffmpeg deprecated, added avconv, which is almost the same for now, except
10 for a few incompatible changes in the options, which will hopefully make them
11 easier to use. The changes are:
12 * -newvideo/-newaudio/-newsubtitle are gone, because they were redundant and
13 worked in a nonstandard way. -map is sufficient to add streams to output
15 * -map now has slightly different and more powerful syntax.
16 + it's possible to specify stream type. E.g. -map 0:a:2 means 'third
18 + omitting the stream index now maps all the streams of the given
19 type, not just the first. E.g. -map 0:s maps all the subtitle streams.
20 + colons (':') are used to separate file index/stream type/stream
21 index. Comma (',') is used to separate the sync stream. This is done
22 for consistency with other options.
23 + since -map can now match multiple streams, negative mappings were
24 introduced. Negative mappings disable some streams from an already
25 defined map. E.g. '-map 0 -map -0:a:1' means 'map everything except
26 for the second audio stream'.
27 * -vcodec/-acodec/-scodec are replaced by -c (or -codec), which
28 allows to precisely specify target stream(s) consistently with other
29 options. E.g. '-c:v libx264' sets the codec for all video streams,
30 '-c:a:0 libvorbis' sets the codec for the first audio stream and '-c
31 copy' copies all the streams.
32 * It is now possible to precisely specify which stream should an AVOption
33 apply to. See the manual for detailed explanation.
34 * -map_chapters now takes only an input file index and applies to the next
35 output file. This is consistent with how all the other options work.
36 * -map_metadata now takes only an input metadata specifier and applies to
37 the next output file. Output metadata specifier is now part of the option
38 name, similarly to the AVOptions/map/codec feature above.
39 * Presets in avconv are disabled, because only libx264 used them and
40 presets for libx264 can now be specified using a private option
41 '-preset <presetname>'.
42 * -intra option was removed, it's equivalent to -g 0.

642 <lists at reserv.at>, but changed completely since we use a format
643 instead of a protocol)
648 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
649 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
650 missing. MSMPEG4 support is complete.
651 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
652 can decode ffmpeg MPEGs :-)).
653 - added libavcodec API documentation (see apiexample.c).
654 - fixed image polyphase bug (the bottom of some images could be
656 - added support for non clipped motion vectors (decoding only)
657 and image sizes non-multiple of 16
658 - added support for AC prediction (decoding only)
659 - added file overwrite confirmation (can be disabled with -y)
660 - added custom size picture to H.263 using H.263+ (Juanjo)
665 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
666 of AVI and ASF to DIV3.
667 - added -me option to set motion estimation method
668 (default=log). suppressed redundant -hq option.
669 - added options -acodec and -vcodec to force a given codec (useful for
672 - improved dct_quantize speed
673 - factorized some motion estimation code
678 - removing grab code from ffserver and moved it to ffmpeg. Added
679 multistream support to ffmpeg.
680 - added timeshifting support for live feeds (option ?date=xxx in the
682 - added high quality image resize code with polyphase filter (need
683 mmx/see optimization). Enable multiple image size support in ffserver.
684 - added multi live feed support in ffserver
685 - suppressed master feature from ffserver (it should be done with an
686 external program which opens the .ffm url and writes it to another
688 - added preliminary support for video stream parsing (WAV and AVI half
689 done). Added proper support for audio/video file conversion in
691 - added preliminary support for video file sending from ffserver
692 - redesigning I/O subsystem: now using URL based input and output
694 - added WAV format support
695 - added "tty user interface" to ffmpeg to stop grabbing gracefully
696 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
697 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
698 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
699 - added new motion estimation algorithms, log and phods (Juanjo)
700 - changed directories: libav for format handling, libavcodec for
706 - added stereo in MPEG audio encoder
711 - added 'high quality' mode which use motion vectors. It can be used in
712 real time at low resolution.
713 - fixed rounding problems which caused quality problems at high
714 bitrates and large GOP size
717 version 0.3.2: small fixes
723 version 0.3.1: added avi/divx support
726 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
727 - added sound for flash format (not tested)
730 version 0.3: initial public release
