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

1274 - added custom size picture to H.263 using H.263+ (Juanjo)
1279 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1280 of AVI and ASF to DIV3.
1281 - added -me option to set motion estimation method
1282 (default=log). suppressed redundant -hq option.
1283 - added options -acodec and -vcodec to force a given codec (useful for
1286 - improved dct_quantize speed
1287 - factorized some motion estimation code
1292 - removing grab code from ffserver and moved it to ffmpeg. Added
1293 multistream support to ffmpeg.
1294 - added timeshifting support for live feeds (option ?date=xxx in the
1296 - added high quality image resize code with polyphase filter (need
1297 mmx/see optimization). Enable multiple image size support in ffserver.
1298 - added multi live feed support in ffserver
1299 - suppressed master feature from ffserver (it should be done with an
1300 external program which opens the .ffm url and writes it to another

1314 - changed directories: libav for format handling, libavcodec for
1320 - added stereo in MPEG audio encoder
1325 - added 'high quality' mode which use motion vectors. It can be used in
1326 real time at low resolution.
1327 - fixed rounding problems which caused quality problems at high
1328 bitrates and large GOP size
1331 version 0.3.2: small fixes
