  1. Entries are sorted chronologically from oldest to youngest within each release,
  2. releases are sorted from youngest to oldest.
  3. version <next>:
  4. - BWF muxer
  5. - Flash Screen Video 2 decoder
  6. - ffplay/ffprobe/ffserver renamed to avplay/avprobe/avserver
  7. - ffmpeg deprecated, added avconv, which is almost the same for now, except
  8. for a few incompatible changes in the options, which will hopefully make them
  9. easier to use. The changes are:
  10. * -newvideo/-newaudio/-newsubtitle are gone, because they were redundant and
  11. worked in a nonstandard way. -map is sufficient to add streams to output
  12. files.
  13. * -map now has slightly different and more powerful syntax.
  14. + it's possible to specify stream type. E.g. -map 0:a:2 means 'third
  15. audio stream'.
  16. + omitting the stream index now maps all the streams of the given
  17. type, not just the first. E.g. -map 0:s maps all the subtitle streams.
  18. + colons (':') are used to separate file index/stream type/stream
  19. index. Comma (',') is used to separate the sync stream. This is done
  20. for consistency with other options.
  21. + since -map can now match multiple streams, negative mappings were
  22. introduced. Negative mappings disable some streams from an already
  23. defined map. E.g. '-map 0 -map -0:a:1' means 'map everything except
  24. for the second audio stream'.
  25. * -vcodec/-acodec/-scodec are replaced by -c (or -codec), which
  26. allows to precisely specify target stream(s) consistently with other
  27. options. E.g. '-c:v libx264' sets the codec for all video streams,
  28. '-c:a:0 libvorbis' sets the codec for the first audio stream and '-c
  29. copy' copies all the streams.
  30. * It is now possible to precisely specify which stream should an AVOption
  31. apply to. See the manual for detailed explanation.
  32. * -map_chapters now takes only an input file index and applies to the next
  33. output file. This is consistent with how all the other options work.
  34. * -map_metadata now takes only an input metadata specifier and applies to
  35. the next output file. Output metadata specifier is now part of the option
  36. name, similarly to the AVOptions/map/codec feature above.
  37. * Presets in avconv are disabled, because only libx264 used them and
  38. presets for libx264 can now be specified using a private option
  39. '-preset <presetname>'.
  40. * -intra option was removed, it's equivalent to -g 0.

  655. done). Added proper support for audio/video file conversion in
