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

1275 - fixed image polyphase bug (the bottom of some images could be
1277 - added support for non clipped motion vectors (decoding only)
1278 and image sizes non-multiple of 16
1279 - added support for AC prediction (decoding only)
1280 - added file overwrite confirmation (can be disabled with -y)
1281 - added custom size picture to H.263 using H.263+ (Juanjo)
1286 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1287 of AVI and ASF to DIV3.
1288 - added -me option to set motion estimation method
1289 (default=log). suppressed redundant -hq option.
1290 - added options -acodec and -vcodec to force a given codec (useful for
1293 - improved dct_quantize speed
1294 - factorized some motion estimation code
1299 - removing grab code from ffserver and moved it to ffmpeg. Added
1300 multistream support to ffmpeg.
1301 - added timeshifting support for live feeds (option ?date=xxx in the
1303 - added high quality image resize code with polyphase filter (need
1304 mmx/see optimization). Enable multiple image size support in ffserver.
1305 - added multi live feed support in ffserver
1306 - suppressed master feature from ffserver (it should be done with an
1307 external program which opens the .ffm url and writes it to another
1309 - added preliminary support for video stream parsing (WAV and AVI half
1310 done). Added proper support for audio/video file conversion in

1319 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1320 - added new motion estimation algorithms, log and phods (Juanjo)
1321 - changed directories: libav for format handling, libavcodec for
1327 - added stereo in MPEG audio encoder
1332 - added 'high quality' mode which use motion vectors. It can be used in
1333 real time at low resolution.
1334 - fixed rounding problems which caused quality problems at high
1335 bitrates and large GOP size
1338 version 0.3.2: small fixes
1344 version 0.3.1: added avi/divx support
1347 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
