553 - Flash Screen Video 2 decoder
554 - lavfi input device added
555 - added avconv, which is almost the same for now, except
556 for a few incompatible changes in the options, which will hopefully make them
557 easier to use. The changes are:
558 * The options placement is now strictly enforced! While in theory the
559 options for ffmpeg should be given in [input options] -i INPUT [output
560 options] OUTPUT order, in practice it was possible to give output options
561 before the -i and it mostly worked. Except when it didn't - the behavior was
562 a bit inconsistent. In avconv, it is not possible to mix input and output
563 options. All non-global options are reset after an input or output filename.
564 * All per-file options are now truly per-file - they apply only to the next
565 input or output file and specifying different values for different files
566 will now work properly (notably -ss and -t options).
567 * All per-stream options are now truly per-stream - it is possible to
568 specify which stream(s) should a given option apply to. See the Stream
569 specifiers section in the avconv manual for details.
570 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
571 sense that they're specified after the output filename instead of before,
572 like all other options. In avconv this irregularity is removed, all options
573 apply to the next input or output file.
574 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
575 irregular and highly confusing, they were also redundant. In avconv the -map
576 option will create new streams in the output file and map input streams to
577 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
578 each stream in the first input file.
579 * The -map option now has slightly different and more powerful syntax:
580 + Colons (':') are used to separate file index/stream type/stream index
581 instead of dots. Comma (',') is used to separate the sync stream instead
582 of colon.. This is done for consistency with other options.
583 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
584 output stream from the third input audio stream.
585 + Omitting the stream index now maps all the streams of the given type,
586 not just the first. E.g. -map 0:s creates output streams for all the
587 subtitle streams in the first input file.
588 + Since -map can now match multiple streams, negative mappings were
589 introduced. Negative mappings disable some streams from an already
590 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
591 all the stream in the first input file, except for the second audio
593 * There is a new option -c (or -codec) for choosing the decoder/encoder to
594 use, which makes it possible to precisely specify target stream(s) consistently with
595 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
596 libvorbis sets the codec for the first audio stream and -c copy copies all
597 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
599 * It is now possible to precisely specify which stream should an AVOption
600 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
601 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
602 syntax is deprecated and will stop working soon.
603 * -map_chapters now takes only an input file index and applies to the next
604 output file. This is consistent with how all the other options work.
605 * -map_metadata now takes only an input metadata specifier and applies to
606 the next output file. Output metadata specifier is now part of the option
607 name, similarly to the AVOptions/map/codec feature above.
608 * -metadata can now be used to set metadata on streams and chapters, e.g.
609 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
610 This made -vlang/-alang/-slang options redundant, so they were removed.
611 * -qscale option now uses stream specifiers and applies to all streams, not
612 just video. I.e. plain -qscale number would now apply to all streams. To get
613 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
614 and -aq is now an alias for -q:a.
615 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
616 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
617 * -itsscale option now uses stream specifiers, so its argument is only the
619 * -intra option was removed, use -g 0 for the same effect.
620 * -psnr option was removed, use -flags +psnr for the same effect.
621 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
622 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
623 * -vtag/-atag/-stag options are now aliases to the new -tag option.

1283 - fixed raw yuv output
1284 - added motion rounding support in MPEG-4
1285 - fixed motion bug rounding in MSMPEG4
1286 - added B-frame handling in video core
1287 - added full MPEG-1 decoding support
1288 - added partial (frame only) MPEG-2 support
1289 - changed the FOURCC code for H.263 to "U263" to be able to see the
1290 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1291 this +codec ;) (JuanJo).
1292 - Halfpel motion estimation after MB type selection (JuanJo)
1293 - added pgm and .Y.U.V output format
1294 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1296 - added pgmpipe I/O format (original patch from Martin Aumueller
1297 <lists at reserv.at>, but changed completely since we use a format
1298 instead of a protocol)
1303 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1304 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1305 missing. MSMPEG4 support is complete.
1306 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1307 can decode ffmpeg MPEGs :-)).
1308 - added libavcodec API documentation (see apiexample.c).
1309 - fixed image polyphase bug (the bottom of some images could be
1311 - added support for non clipped motion vectors (decoding only)
1312 and image sizes non-multiple of 16
1313 - added support for AC prediction (decoding only)
1314 - added file overwrite confirmation (can be disabled with -y)
1315 - added custom size picture to H.263 using H.263+ (Juanjo)
1320 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1321 of AVI and ASF to DIV3.
1322 - added -me option to set motion estimation method
1323 (default=log). suppressed redundant -hq option.
1324 - added options -acodec and -vcodec to force a given codec (useful for
1327 - improved dct_quantize speed
1328 - factorized some motion estimation code
1333 - removing grab code from ffserver and moved it to ffmpeg. Added
1334 multistream support to ffmpeg.
1335 - added timeshifting support for live feeds (option ?date=xxx in the
1337 - added high quality image resize code with polyphase filter (need
1338 mmx/see optimization). Enable multiple image size support in ffserver.
1339 - added multi live feed support in ffserver
1340 - suppressed master feature from ffserver (it should be done with an
1341 external program which opens the .ffm url and writes it to another
1343 - added preliminary support for video stream parsing (WAV and AVI half
1344 done). Added proper support for audio/video file conversion in
1346 - added preliminary support for video file sending from ffserver
1347 - redesigning I/O subsystem: now using URL based input and output
1349 - added WAV format support
1350 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1351 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1352 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1353 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1354 - added new motion estimation algorithms, log and phods (Juanjo)
1355 - changed directories: libav for format handling, libavcodec for
1361 - added stereo in MPEG audio encoder
1366 - added 'high quality' mode which use motion vectors. It can be used in
1367 real time at low resolution.
1368 - fixed rounding problems which caused quality problems at high
1369 bitrates and large GOP size
1372 version 0.3.2: small fixes
1378 version 0.3.1: added avi/divx support
1381 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1382 - added sound for flash format (not tested)
1385 version 0.3: initial public release
