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

1281 - added full MPEG-1 decoding support
1282 - added partial (frame only) MPEG-2 support
1283 - changed the FOURCC code for H.263 to "U263" to be able to see the
1284 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1285 this +codec ;) (JuanJo).
1286 - Halfpel motion estimation after MB type selection (JuanJo)
1287 - added pgm and .Y.U.V output format
1288 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1290 - added pgmpipe I/O format (original patch from Martin Aumueller
1291 <lists at reserv.at>, but changed completely since we use a format
1292 instead of a protocol)
1297 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1298 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1299 missing. MSMPEG4 support is complete.
1300 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1301 can decode ffmpeg MPEGs :-)).
1302 - added libavcodec API documentation (see apiexample.c).
1303 - fixed image polyphase bug (the bottom of some images could be
1305 - added support for non clipped motion vectors (decoding only)
1306 and image sizes non-multiple of 16
1307 - added support for AC prediction (decoding only)
1308 - added file overwrite confirmation (can be disabled with -y)
1309 - added custom size picture to H.263 using H.263+ (Juanjo)
1314 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1315 of AVI and ASF to DIV3.
1316 - added -me option to set motion estimation method
1317 (default=log). suppressed redundant -hq option.
1318 - added options -acodec and -vcodec to force a given codec (useful for
1321 - improved dct_quantize speed
1322 - factorized some motion estimation code
1327 - removing grab code from ffserver and moved it to ffmpeg. Added
1328 multistream support to ffmpeg.
1329 - added timeshifting support for live feeds (option ?date=xxx in the
1331 - added high quality image resize code with polyphase filter (need
1332 mmx/see optimization). Enable multiple image size support in ffserver.
1333 - added multi live feed support in ffserver
1334 - suppressed master feature from ffserver (it should be done with an
1335 external program which opens the .ffm url and writes it to another
1337 - added preliminary support for video stream parsing (WAV and AVI half
1338 done). Added proper support for audio/video file conversion in
1340 - added preliminary support for video file sending from ffserver
1341 - redesigning I/O subsystem: now using URL based input and output
1343 - added WAV format support
1344 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1345 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1346 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1347 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1348 - added new motion estimation algorithms, log and phods (Juanjo)
1349 - changed directories: libav for format handling, libavcodec for
1355 - added stereo in MPEG audio encoder
1360 - added 'high quality' mode which use motion vectors. It can be used in
1361 real time at low resolution.
1362 - fixed rounding problems which caused quality problems at high
1363 bitrates and large GOP size
1366 version 0.3.2: small fixes
1372 version 0.3.1: added avi/divx support
1375 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1376 - added sound for flash format (not tested)
1379 version 0.3: initial public release
