  983 - boxblur filter added
  984 - BWF muxer
  985 - Flash Screen Video 2 decoder
  986 - lavfi input device added
  987 - added avconv, which is almost the same for now, except
  988 for a few incompatible changes in the options, which will hopefully make them
  989 easier to use. The changes are:
  990     * The options placement is now strictly enforced! While in theory the
  991       options for ffmpeg should be given in [input options] -i INPUT [output
  992       options] OUTPUT order, in practice it was possible to give output options
  993       before the -i and it mostly worked. Except when it didn't - the behavior was
  994       a bit inconsistent. In avconv, it is not possible to mix input and output
  995       options. All non-global options are reset after an input or output filename.
  996     * All per-file options are now truly per-file - they apply only to the next
  997       input or output file and specifying different values for different files
  998       will now work properly (notably -ss and -t options).
  999     * All per-stream options are now truly per-stream - it is possible to
 1000       specify which stream(s) should a given option apply to. See the Stream
 1001       specifiers section in the avconv manual for details.
 1002     * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
 1003       sense that they're specified after the output filename instead of before,
 1004       like all other options. In avconv this irregularity is removed, all options
 1005       apply to the next input or output file.
 1006     * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
 1007       irregular and highly confusing, they were also redundant. In avconv the -map
 1008       option will create new streams in the output file and map input streams to
 1009       them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
 1010       each stream in the first input file.
 1011     * The -map option now has slightly different and more powerful syntax:
 1012         + Colons (':') are used to separate file index/stream type/stream index
 1013           instead of dots. Comma (',') is used to separate the sync stream instead
 1014           of colon.. This is done for consistency with other options.
 1015         + It's possible to specify stream type. E.g. -map 0:a:2 creates an
 1016           output stream from the third input audio stream.
 1017         + Omitting the stream index now maps all the streams of the given type,
 1018           not just the first. E.g. -map 0:s creates output streams for all the
 1019           subtitle streams in the first input file.
 1020         + Since -map can now match multiple streams, negative mappings were
 1021           introduced. Negative mappings disable some streams from an already
 1022           defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
 1023           all the stream in the first input file, except for the second audio
 1024           stream'.
 1025     * There is a new option -c (or -codec) for choosing the decoder/encoder to
 1026       use, which makes it possible to precisely specify target stream(s) consistently with
 1027       other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
 1028       libvorbis sets the codec for the first audio stream and -c copy copies all
 1029       the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
 1030       aliases to -c:v/a/s
 1031     * It is now possible to precisely specify which stream should an AVOption
 1032       apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
 1033       -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
 1034       syntax is deprecated and will stop working soon.
 1035     * -map_chapters now takes only an input file index and applies to the next
 1036       output file. This is consistent with how all the other options work.
 1037     * -map_metadata now takes only an input metadata specifier and applies to
 1038       the next output file. Output metadata specifier is now part of the option
 1039       name, similarly to the AVOptions/map/codec feature above.
 1040     * -metadata can now be used to set metadata on streams and chapters, e.g.
 1041       -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
 1042       This made -vlang/-alang/-slang options redundant, so they were removed.
 1043     * -qscale option now uses stream specifiers and applies to all streams, not
 1044       just video. I.e. plain -qscale number would now apply to all streams. To get
 1045       the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
 1046       and -aq is now an alias for -q:a.
 1047     * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
 1048       uses stream specifiers. Use -bsf:v/a/s instead of the old options.
 1049     * -itsscale option now uses stream specifiers, so its argument is only the
 1050       scale parameter.
 1051     * -intra option was removed, use -g 0 for the same effect.
 1052     * -psnr option was removed, use -flags +psnr for the same effect.
 1053     * -vf option is now an alias to the new -filter option, which uses stream specifiers.
 1054     * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
 1055     * -vtag/-atag/-stag options are now aliases to the new -tag option.
