- ffmpeg deprecated, added avconv, which is almost the same for now, except
for a few incompatible changes in the options, which will hopefully make them
easier to use. The changes are:
    * -newvideo/-newaudio/-newsubtitle are gone, because they were redundant and
      worked in a nonstandard way. -map is sufficient to add streams to output
      files.
    * -map now has slightly different and more powerful syntax.
        + it's possible to specify stream type. E.g. -map 0:a:2 means 'third
          audio stream'.
        + omitting the stream index now maps all the streams of the given
          type, not just the first. E.g. -map 0:s maps all the subtitle streams.
        + colons (':') are used to separate file index/stream type/stream
          index. Comma (',') is used to separate the sync stream. This is done
          for consistency with other options.
        + since -map can now match multiple streams, negative mappings were
          introduced. Negative mappings disable some streams from an already
          defined map. E.g. '-map 0 -map -0:a:1' means 'map everything except
          for the second audio stream'.
    * -vcodec/-acodec/-scodec are replaced by -c (or -codec), which
      allows to precisely specify target stream(s) consistently with other
      options. E.g. '-c:v libx264' sets the codec for all video streams,
      '-c:a:0 libvorbis' sets the codec for the first audio stream and '-c
      copy' copies all the streams.
    * It is now possible to precisely specify which stream should an AVOption
      apply to. See the manual for detailed explanation.
    * -map_chapters now takes only an input file index and applies to the next
      output file. This is consistent with how all the other options work.
    * -map_metadata now takes only an input metadata specifier and applies to
      the next output file. Output metadata specifier is now part of the option
      name, similarly to the AVOptions/map/codec feature above.
    * Presets in avconv are disabled, because only libx264 used them and
      presets for libx264 can now be specified using a private option
      '-preset <presetname>'.
