  917. - openal input device added
  918. - boxblur filter added
  919. - BWF muxer
  920. - Flash Screen Video 2 decoder
  921. - lavfi input device added
  922. - added avconv, which is almost the same for now, except
  923. for a few incompatible changes in the options, which will hopefully make them
  924. easier to use. The changes are:
  925. * The options placement is now strictly enforced! While in theory the
  926. options for ffmpeg should be given in [input options] -i INPUT [output
  927. options] OUTPUT order, in practice it was possible to give output options
  928. before the -i and it mostly worked. Except when it didn't - the behavior was
  929. a bit inconsistent. In avconv, it is not possible to mix input and output
  930. options. All non-global options are reset after an input or output filename.
  931. * All per-file options are now truly per-file - they apply only to the next
  932. input or output file and specifying different values for different files
  933. will now work properly (notably -ss and -t options).
  934. * All per-stream options are now truly per-stream - it is possible to
  935. specify which stream(s) should a given option apply to. See the Stream
  936. specifiers section in the avconv manual for details.
  937. * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
  938. sense that they're specified after the output filename instead of before,
  939. like all other options. In avconv this irregularity is removed, all options
  940. apply to the next input or output file.
  941. * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
  942. irregular and highly confusing, they were also redundant. In avconv the -map
  943. option will create new streams in the output file and map input streams to
  944. them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
  945. each stream in the first input file.
  946. * The -map option now has slightly different and more powerful syntax:
  947. + Colons (':') are used to separate file index/stream type/stream index
  948. instead of dots. Comma (',') is used to separate the sync stream instead
  949. of colon.. This is done for consistency with other options.
  950. + It's possible to specify stream type. E.g. -map 0:a:2 creates an
  951. output stream from the third input audio stream.
  952. + Omitting the stream index now maps all the streams of the given type,
  953. not just the first. E.g. -map 0:s creates output streams for all the
  954. subtitle streams in the first input file.
  955. + Since -map can now match multiple streams, negative mappings were
  956. introduced. Negative mappings disable some streams from an already
  957. defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
  958. all the stream in the first input file, except for the second audio
  959. stream'.
  960. * There is a new option -c (or -codec) for choosing the decoder/encoder to
  961. use, which makes it possible to precisely specify target stream(s) consistently with
  962. other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
  963. libvorbis sets the codec for the first audio stream and -c copy copies all
  964. the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
  965. aliases to -c:v/a/s
  966. * It is now possible to precisely specify which stream should an AVOption
  967. apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
  968. -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
  969. syntax is deprecated and will stop working soon.
  970. * -map_chapters now takes only an input file index and applies to the next
  971. output file. This is consistent with how all the other options work.
  972. * -map_metadata now takes only an input metadata specifier and applies to
  973. the next output file. Output metadata specifier is now part of the option
  974. name, similarly to the AVOptions/map/codec feature above.
  975. * -metadata can now be used to set metadata on streams and chapters, e.g.
  976. -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
  977. This made -vlang/-alang/-slang options redundant, so they were removed.
  978. * -qscale option now uses stream specifiers and applies to all streams, not
  979. just video. I.e. plain -qscale number would now apply to all streams. To get
  980. the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
  981. and -aq is now an alias for -q:a.
  982. * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
  983. uses stream specifiers. Use -bsf:v/a/s instead of the old options.
  984. * -itsscale option now uses stream specifiers, so its argument is only the
  985. scale parameter.
  986. * -intra option was removed, use -g 0 for the same effect.
  987. * -psnr option was removed, use -flags +psnr for the same effect.
  988. * -vf option is now an alias to the new -filter option, which uses stream specifiers.
  989. * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
  990. * -vtag/-atag/-stag options are now aliases to the new -tag option.
