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

1273 - improved dct_quantize speed
1274 - factorized some motion estimation code
1279 - removing grab code from ffserver and moved it to ffmpeg. Added
1280 multistream support to ffmpeg.
1281 - added timeshifting support for live feeds (option ?date=xxx in the
1283 - added high quality image resize code with polyphase filter (need
1284 mmx/see optimization). Enable multiple image size support in ffserver.
1285 - added multi live feed support in ffserver
1286 - suppressed master feature from ffserver (it should be done with an
1287 external program which opens the .ffm url and writes it to another
1289 - added preliminary support for video stream parsing (WAV and AVI half
1290 done). Added proper support for audio/video file conversion in
1292 - added preliminary support for video file sending from ffserver
1293 - redesigning I/O subsystem: now using URL based input and output
1295 - added WAV format support
1296 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1297 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1298 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1299 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1300 - added new motion estimation algorithms, log and phods (Juanjo)
1301 - changed directories: libav for format handling, libavcodec for
1307 - added stereo in MPEG audio encoder
1312 - added 'high quality' mode which use motion vectors. It can be used in
1313 real time at low resolution.
1314 - fixed rounding problems which caused quality problems at high
1315 bitrates and large GOP size
1318 version 0.3.2: small fixes
1324 version 0.3.1: added avi/divx support
1327 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1328 - added sound for flash format (not tested)
