1277 - Flash Screen Video 2 decoder
1278 - lavfi input device added
1279 - added avconv, which is almost the same for now, except
1280 for a few incompatible changes in the options, which will hopefully make them
1281 easier to use. The changes are:
1282 * The options placement is now strictly enforced! While in theory the
1283 options for ffmpeg should be given in [input options] -i INPUT [output
1284 options] OUTPUT order, in practice it was possible to give output options
1285 before the -i and it mostly worked. Except when it didn't - the behavior was
1286 a bit inconsistent. In avconv, it is not possible to mix input and output
1287 options. All non-global options are reset after an input or output filename.
1288 * All per-file options are now truly per-file - they apply only to the next
1289 input or output file and specifying different values for different files
1290 will now work properly (notably -ss and -t options).
1291 * All per-stream options are now truly per-stream - it is possible to
1292 specify which stream(s) should a given option apply to. See the Stream
1293 specifiers section in the avconv manual for details.
1294 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
1295 sense that they're specified after the output filename instead of before,
1296 like all other options. In avconv this irregularity is removed, all options
1297 apply to the next input or output file.
1298 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
1299 irregular and highly confusing, they were also redundant. In avconv the -map
1300 option will create new streams in the output file and map input streams to
1301 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
1302 each stream in the first input file.
1303 * The -map option now has slightly different and more powerful syntax:
1304 + Colons (':') are used to separate file index/stream type/stream index
1305 instead of dots. Comma (',') is used to separate the sync stream instead
1306 of colon.. This is done for consistency with other options.
1307 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
1308 output stream from the third input audio stream.
1309 + Omitting the stream index now maps all the streams of the given type,
1310 not just the first. E.g. -map 0:s creates output streams for all the
1311 subtitle streams in the first input file.
1312 + Since -map can now match multiple streams, negative mappings were
1313 introduced. Negative mappings disable some streams from an already
1314 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
1315 all the stream in the first input file, except for the second audio
1317 * There is a new option -c (or -codec) for choosing the decoder/encoder to
1318 use, which makes it possible to precisely specify target stream(s) consistently with
1319 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
1320 libvorbis sets the codec for the first audio stream and -c copy copies all
1321 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
1323 * It is now possible to precisely specify which stream should an AVOption
1324 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
1325 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
1326 syntax is deprecated and will stop working soon.
1327 * -map_chapters now takes only an input file index and applies to the next
1328 output file. This is consistent with how all the other options work.
1329 * -map_metadata now takes only an input metadata specifier and applies to
1330 the next output file. Output metadata specifier is now part of the option
1331 name, similarly to the AVOptions/map/codec feature above.
1332 * -metadata can now be used to set metadata on streams and chapters, e.g.
1333 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
1334 This made -vlang/-alang/-slang options redundant, so they were removed.
1335 * -qscale option now uses stream specifiers and applies to all streams, not
1336 just video. I.e. plain -qscale number would now apply to all streams. To get
1337 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
1338 and -aq is now an alias for -q:a.
1339 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
1340 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
1341 * -itsscale option now uses stream specifiers, so its argument is only the
1343 * -intra option was removed, use -g 0 for the same effect.
1344 * -psnr option was removed, use -flags +psnr for the same effect.
1345 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
1346 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
1347 * -vtag/-atag/-stag options are now aliases to the new -tag option.

2014 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
2015 this +codec ;) (JuanJo).
2016 - Halfpel motion estimation after MB type selection (JuanJo)
2017 - added pgm and .Y.U.V output format
2018 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
2020 - added pgmpipe I/O format (original patch from Martin Aumueller
2021 <lists at reserv.at>, but changed completely since we use a format
2022 instead of a protocol)
2027 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
2028 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
2029 missing. MSMPEG4 support is complete.
2030 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
2031 can decode ffmpeg MPEGs :-)).
2032 - added libavcodec API documentation (see apiexample.c).
2033 - fixed image polyphase bug (the bottom of some images could be
2035 - added support for non clipped motion vectors (decoding only)
2036 and image sizes non-multiple of 16
2037 - added support for AC prediction (decoding only)
2038 - added file overwrite confirmation (can be disabled with -y)
2039 - added custom size picture to H.263 using H.263+ (Juanjo)
2044 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
2045 of AVI and ASF to DIV3.
2046 - added -me option to set motion estimation method
2047 (default=log). suppressed redundant -hq option.
2048 - added options -acodec and -vcodec to force a given codec (useful for
2051 - improved dct_quantize speed
2052 - factorized some motion estimation code
2057 - removing grab code from ffserver and moved it to ffmpeg. Added
2058 multistream support to ffmpeg.
2059 - added timeshifting support for live feeds (option ?date=xxx in the
2061 - added high quality image resize code with polyphase filter (need
2062 mmx/see optimization). Enable multiple image size support in ffserver.
2063 - added multi live feed support in ffserver
2064 - suppressed master feature from ffserver (it should be done with an
2065 external program which opens the .ffm url and writes it to another
2067 - added preliminary support for video stream parsing (WAV and AVI half
2068 done). Added proper support for audio/video file conversion in
2070 - added preliminary support for video file sending from ffserver
2071 - redesigning I/O subsystem: now using URL based input and output
2073 - added WAV format support
2074 - added "tty user interface" to ffmpeg to stop grabbing gracefully
2075 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
2076 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
2077 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
2078 - added new motion estimation algorithms, log and phods (Juanjo)
2079 - changed directories: libav for format handling, libavcodec for
2085 - added stereo in MPEG audio encoder
2090 - added 'high quality' mode which use motion vectors. It can be used in
2091 real time at low resolution.
2092 - fixed rounding problems which caused quality problems at high
2093 bitrates and large GOP size
2096 version 0.3.2: small fixes
2102 version 0.3.1: added avi/divx support
2105 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
2106 - added sound for flash format (not tested)
2109 version 0.3: initial public release
