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

1280 - added full MPEG-1 decoding support
1281 - added partial (frame only) MPEG-2 support
1282 - changed the FOURCC code for H.263 to "U263" to be able to see the
1283 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1284 this +codec ;) (JuanJo).
1285 - Halfpel motion estimation after MB type selection (JuanJo)
1286 - added pgm and .Y.U.V output format
1287 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1289 - added pgmpipe I/O format (original patch from Martin Aumueller
1290 <lists at reserv.at>, but changed completely since we use a format
1291 instead of a protocol)
1296 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1297 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1298 missing. MSMPEG4 support is complete.
1299 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1300 can decode ffmpeg MPEGs :-)).
1301 - added libavcodec API documentation (see apiexample.c).
1302 - fixed image polyphase bug (the bottom of some images could be
1304 - added support for non clipped motion vectors (decoding only)
1305 and image sizes non-multiple of 16
1306 - added support for AC prediction (decoding only)
1307 - added file overwrite confirmation (can be disabled with -y)
1308 - added custom size picture to H.263 using H.263+ (Juanjo)
1313 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1314 of AVI and ASF to DIV3.
1315 - added -me option to set motion estimation method
1316 (default=log). suppressed redundant -hq option.
1317 - added options -acodec and -vcodec to force a given codec (useful for
1320 - improved dct_quantize speed
1321 - factorized some motion estimation code
1326 - removing grab code from ffserver and moved it to ffmpeg. Added
1327 multistream support to ffmpeg.
1328 - added timeshifting support for live feeds (option ?date=xxx in the
1330 - added high quality image resize code with polyphase filter (need
1331 mmx/see optimization). Enable multiple image size support in ffserver.
1332 - added multi live feed support in ffserver
1333 - suppressed master feature from ffserver (it should be done with an
1334 external program which opens the .ffm url and writes it to another
1336 - added preliminary support for video stream parsing (WAV and AVI half
1337 done). Added proper support for audio/video file conversion in
1339 - added preliminary support for video file sending from ffserver
1340 - redesigning I/O subsystem: now using URL based input and output
1342 - added WAV format support
1343 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1344 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1345 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1346 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1347 - added new motion estimation algorithms, log and phods (Juanjo)
1348 - changed directories: libav for format handling, libavcodec for
1354 - added stereo in MPEG audio encoder
1359 - added 'high quality' mode which use motion vectors. It can be used in
1360 real time at low resolution.
1361 - fixed rounding problems which caused quality problems at high
1362 bitrates and large GOP size
1365 version 0.3.2: small fixes
1371 version 0.3.1: added avi/divx support
1374 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1375 - added sound for flash format (not tested)
1378 version 0.3: initial public release
