650 - lavfi input device added
651 - added avconv, which is almost the same for now, except
652 for a few incompatible changes in the options, which will hopefully make them
653 easier to use. The changes are:
654 * The options placement is now strictly enforced! While in theory the
655 options for ffmpeg should be given in [input options] -i INPUT [output
656 options] OUTPUT order, in practice it was possible to give output options
657 before the -i and it mostly worked. Except when it didn't - the behavior was
658 a bit inconsistent. In avconv, it is not possible to mix input and output
659 options. All non-global options are reset after an input or output filename.
660 * All per-file options are now truly per-file - they apply only to the next
661 input or output file and specifying different values for different files
662 will now work properly (notably -ss and -t options).
663 * All per-stream options are now truly per-stream - it is possible to
664 specify which stream(s) should a given option apply to. See the Stream
665 specifiers section in the avconv manual for details.
666 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
667 sense that they're specified after the output filename instead of before,
668 like all other options. In avconv this irregularity is removed, all options
669 apply to the next input or output file.
670 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
671 irregular and highly confusing, they were also redundant. In avconv the -map
672 option will create new streams in the output file and map input streams to
673 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
674 each stream in the first input file.
675 * The -map option now has slightly different and more powerful syntax:
676 + Colons (':') are used to separate file index/stream type/stream index
677 instead of dots. Comma (',') is used to separate the sync stream instead
678 of colon.. This is done for consistency with other options.
679 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
680 output stream from the third input audio stream.
681 + Omitting the stream index now maps all the streams of the given type,
682 not just the first. E.g. -map 0:s creates output streams for all the
683 subtitle streams in the first input file.
684 + Since -map can now match multiple streams, negative mappings were
685 introduced. Negative mappings disable some streams from an already
686 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
687 all the stream in the first input file, except for the second audio
689 * There is a new option -c (or -codec) for choosing the decoder/encoder to
690 use, which makes it possible to precisely specify target stream(s) consistently with
691 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
692 libvorbis sets the codec for the first audio stream and -c copy copies all
693 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
695 * It is now possible to precisely specify which stream should an AVOption
696 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
697 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
698 syntax is deprecated and will stop working soon.
699 * -map_chapters now takes only an input file index and applies to the next
700 output file. This is consistent with how all the other options work.
701 * -map_metadata now takes only an input metadata specifier and applies to
702 the next output file. Output metadata specifier is now part of the option
703 name, similarly to the AVOptions/map/codec feature above.
704 * -metadata can now be used to set metadata on streams and chapters, e.g.
705 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
706 This made -vlang/-alang/-slang options redundant, so they were removed.
707 * -qscale option now uses stream specifiers and applies to all streams, not
708 just video. I.e. plain -qscale number would now apply to all streams. To get
709 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
710 and -aq is now an alias for -q:a.
711 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
712 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
713 * -itsscale option now uses stream specifiers, so its argument is only the
715 * -intra option was removed, use -g 0 for the same effect.
716 * -psnr option was removed, use -flags +psnr for the same effect.
717 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
718 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
719 * -vtag/-atag/-stag options are now aliases to the new -tag option.

1385 - changed the FOURCC code for H.263 to "U263" to be able to see the
1386 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1387 this +codec ;) (JuanJo).
1388 - Halfpel motion estimation after MB type selection (JuanJo)
1389 - added pgm and .Y.U.V output format
1390 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1392 - added pgmpipe I/O format (original patch from Martin Aumueller
1393 <lists at reserv.at>, but changed completely since we use a format
1394 instead of a protocol)
1399 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support

1437 external program which opens the .ffm url and writes it to another
