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

1273 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1274 of AVI and ASF to DIV3.
1275 - added -me option to set motion estimation method
1276 (default=log). suppressed redundant -hq option.
1277 - added options -acodec and -vcodec to force a given codec (useful for
1280 - improved dct_quantize speed
1281 - factorized some motion estimation code
1286 - removing grab code from ffserver and moved it to ffmpeg. Added
1287 multistream support to ffmpeg.
1288 - added timeshifting support for live feeds (option ?date=xxx in the
1290 - added high quality image resize code with polyphase filter (need
1291 mmx/see optimization). Enable multiple image size support in ffserver.
1292 - added multi live feed support in ffserver
1293 - suppressed master feature from ffserver (it should be done with an
1294 external program which opens the .ffm url and writes it to another
1296 - added preliminary support for video stream parsing (WAV and AVI half
1297 done). Added proper support for audio/video file conversion in

1306 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1307 - added new motion estimation algorithms, log and phods (Juanjo)
1308 - changed directories: libav for format handling, libavcodec for
1314 - added stereo in MPEG audio encoder
1319 - added 'high quality' mode which use motion vectors. It can be used in
1320 real time at low resolution.
1321 - fixed rounding problems which caused quality problems at high
1322 bitrates and large GOP size
1325 version 0.3.2: small fixes
1331 version 0.3.1: added avi/divx support
1334 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
