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

1384 - changed the FOURCC code for H.263 to "U263" to be able to see the
1385 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1386 this +codec ;) (JuanJo).
1387 - Halfpel motion estimation after MB type selection (JuanJo)
1388 - added pgm and .Y.U.V output format
1389 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1391 - added pgmpipe I/O format (original patch from Martin Aumueller
1392 <lists at reserv.at>, but changed completely since we use a format
1393 instead of a protocol)
1398 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support

1422 - improved dct_quantize speed
1423 - factorized some motion estimation code

1436 external program which opens the .ffm url and writes it to another
