501 - Flash Screen Video 2 decoder
502 - lavfi input device added
503 - added avconv, which is almost the same for now, except
504 for a few incompatible changes in the options, which will hopefully make them
505 easier to use. The changes are:
506 * The options placement is now strictly enforced! While in theory the
507 options for ffmpeg should be given in [input options] -i INPUT [output
508 options] OUTPUT order, in practice it was possible to give output options
509 before the -i and it mostly worked. Except when it didn't - the behavior was
510 a bit inconsistent. In avconv, it is not possible to mix input and output
511 options. All non-global options are reset after an input or output filename.
512 * All per-file options are now truly per-file - they apply only to the next
513 input or output file and specifying different values for different files
514 will now work properly (notably -ss and -t options).
515 * All per-stream options are now truly per-stream - it is possible to
516 specify which stream(s) should a given option apply to. See the Stream
517 specifiers section in the avconv manual for details.
518 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
519 sense that they're specified after the output filename instead of before,
520 like all other options. In avconv this irregularity is removed, all options
521 apply to the next input or output file.
522 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
523 irregular and highly confusing, they were also redundant. In avconv the -map
524 option will create new streams in the output file and map input streams to
525 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
526 each stream in the first input file.
527 * The -map option now has slightly different and more powerful syntax:
528 + Colons (':') are used to separate file index/stream type/stream index
529 instead of dots. Comma (',') is used to separate the sync stream instead
530 of colon.. This is done for consistency with other options.
531 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
532 output stream from the third input audio stream.
533 + Omitting the stream index now maps all the streams of the given type,
534 not just the first. E.g. -map 0:s creates output streams for all the
535 subtitle streams in the first input file.
536 + Since -map can now match multiple streams, negative mappings were
537 introduced. Negative mappings disable some streams from an already
538 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
539 all the stream in the first input file, except for the second audio
541 * There is a new option -c (or -codec) for choosing the decoder/encoder to
542 use, which allows to precisely specify target stream(s) consistently with
543 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
544 libvorbis sets the codec for the first audio stream and -c copy copies all
545 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
547 * It is now possible to precisely specify which stream should an AVOption
548 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
549 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
550 syntax is deprecated and will stop working soon.
551 * -map_chapters now takes only an input file index and applies to the next
552 output file. This is consistent with how all the other options work.
553 * -map_metadata now takes only an input metadata specifier and applies to
554 the next output file. Output metadata specifier is now part of the option
555 name, similarly to the AVOptions/map/codec feature above.
556 * -metadata can now be used to set metadata on streams and chapters, e.g.
557 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
558 This made -vlang/-alang/-slang options redundant, so they were removed.
559 * -qscale option now uses stream specifiers and applies to all streams, not
560 just video. I.e. plain -qscale number would now apply to all streams. To get
561 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
562 and -aq is now an alias for -q:a.
563 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
564 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
565 * -itsscale option now uses stream specifiers, so its argument is only the
567 * -intra option was removed, use -g 0 for the same effect.
568 * -psnr option was removed, use -flags +psnr for the same effect.
569 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
570 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
571 * -vtag/-atag/-stag options are now aliases to the new -tag option.

1271 (default=log). suppressed redundant -hq option.
1272 - added options -acodec and -vcodec to force a given codec (useful for
1275 - improved dct_quantize speed
1276 - factorized some motion estimation code
1281 - removing grab code from ffserver and moved it to ffmpeg. Added
1282 multistream support to ffmpeg.
1283 - added timeshifting support for live feeds (option ?date=xxx in the
1285 - added high quality image resize code with polyphase filter (need
1286 mmx/see optimization). Enable multiple image size support in ffserver.
1287 - added multi live feed support in ffserver
1288 - suppressed master feature from ffserver (it should be done with an
1289 external program which opens the .ffm url and writes it to another
1291 - added preliminary support for video stream parsing (WAV and AVI half
1292 done). Added proper support for audio/video file conversion in
1294 - added preliminary support for video file sending from ffserver
1295 - redesigning I/O subsystem: now using URL based input and output
1297 - added WAV format support
1298 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1299 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1300 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1301 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1302 - added new motion estimation algorithms, log and phods (Juanjo)
1303 - changed directories: libav for format handling, libavcodec for
1309 - added stereo in MPEG audio encoder
1314 - added 'high quality' mode which use motion vectors. It can be used in
1315 real time at low resolution.
1316 - fixed rounding problems which caused quality problems at high
1317 bitrates and large GOP size
1320 version 0.3.2: small fixes
1326 version 0.3.1: added avi/divx support
1329 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1330 - added sound for flash format (not tested)
1333 version 0.3: initial public release
