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

647 - fixed motion bug rounding in MSMPEG4
648 - added B-frame handling in video core
649 - added full MPEG-1 decoding support
650 - added partial (frame only) MPEG-2 support
651 - changed the FOURCC code for H.263 to "U263" to be able to see the
652 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
653 this +codec ;) (JuanJo).
654 - Halfpel motion estimation after MB type selection (JuanJo)
655 - added pgm and .Y.U.V output format
656 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
658 - added pgmpipe I/O format (original patch from Martin Aumueller
659 <lists at reserv.at>, but changed completely since we use a format
660 instead of a protocol)
665 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
666 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
667 missing. MSMPEG4 support is complete.
668 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
669 can decode ffmpeg MPEGs :-)).
670 - added libavcodec API documentation (see apiexample.c).
671 - fixed image polyphase bug (the bottom of some images could be
673 - added support for non clipped motion vectors (decoding only)
674 and image sizes non-multiple of 16
675 - added support for AC prediction (decoding only)
676 - added file overwrite confirmation (can be disabled with -y)
677 - added custom size picture to H.263 using H.263+ (Juanjo)
682 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
683 of AVI and ASF to DIV3.
684 - added -me option to set motion estimation method
685 (default=log). suppressed redundant -hq option.
686 - added options -acodec and -vcodec to force a given codec (useful for
689 - improved dct_quantize speed
690 - factorized some motion estimation code
695 - removing grab code from ffserver and moved it to ffmpeg. Added
696 multistream support to ffmpeg.
697 - added timeshifting support for live feeds (option ?date=xxx in the
699 - added high quality image resize code with polyphase filter (need
700 mmx/see optimization). Enable multiple image size support in ffserver.
701 - added multi live feed support in ffserver
702 - suppressed master feature from ffserver (it should be done with an
703 external program which opens the .ffm url and writes it to another
705 - added preliminary support for video stream parsing (WAV and AVI half
706 done). Added proper support for audio/video file conversion in
708 - added preliminary support for video file sending from ffserver
709 - redesigning I/O subsystem: now using URL based input and output
711 - added WAV format support
712 - added "tty user interface" to ffmpeg to stop grabbing gracefully
713 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
714 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
715 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
716 - added new motion estimation algorithms, log and phods (Juanjo)
717 - changed directories: libav for format handling, libavcodec for
723 - added stereo in MPEG audio encoder
728 - added 'high quality' mode which use motion vectors. It can be used in
729 real time at low resolution.
730 - fixed rounding problems which caused quality problems at high
731 bitrates and large GOP size
734 version 0.3.2: small fixes
740 version 0.3.1: added avi/divx support
743 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
744 - added sound for flash format (not tested)
747 version 0.3: initial public release
