  838. - openal input device added
  839. - boxblur filter added
  840. - BWF muxer
  841. - Flash Screen Video 2 decoder
  842. - lavfi input device added
  843. - added avconv, which is almost the same for now, except
  844. for a few incompatible changes in the options, which will hopefully make them
  845. easier to use. The changes are:
  846. * The options placement is now strictly enforced! While in theory the
  847. options for ffmpeg should be given in [input options] -i INPUT [output
  848. options] OUTPUT order, in practice it was possible to give output options
  849. before the -i and it mostly worked. Except when it didn't - the behavior was
  850. a bit inconsistent. In avconv, it is not possible to mix input and output
  851. options. All non-global options are reset after an input or output filename.
  852. * All per-file options are now truly per-file - they apply only to the next
  853. input or output file and specifying different values for different files
  854. will now work properly (notably -ss and -t options).
  855. * All per-stream options are now truly per-stream - it is possible to
  856. specify which stream(s) should a given option apply to. See the Stream
  857. specifiers section in the avconv manual for details.
  858. * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
  859. sense that they're specified after the output filename instead of before,
  860. like all other options. In avconv this irregularity is removed, all options
  861. apply to the next input or output file.
  862. * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
  863. irregular and highly confusing, they were also redundant. In avconv the -map
  864. option will create new streams in the output file and map input streams to
  865. them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
  866. each stream in the first input file.
  867. * The -map option now has slightly different and more powerful syntax:
  868. + Colons (':') are used to separate file index/stream type/stream index
  869. instead of dots. Comma (',') is used to separate the sync stream instead
  870. of colon.. This is done for consistency with other options.
  871. + It's possible to specify stream type. E.g. -map 0:a:2 creates an
  872. output stream from the third input audio stream.
  873. + Omitting the stream index now maps all the streams of the given type,
  874. not just the first. E.g. -map 0:s creates output streams for all the
  875. subtitle streams in the first input file.
  876. + Since -map can now match multiple streams, negative mappings were
  877. introduced. Negative mappings disable some streams from an already
  878. defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
  879. all the stream in the first input file, except for the second audio
  880. stream'.
  881. * There is a new option -c (or -codec) for choosing the decoder/encoder to
  882. use, which makes it possible to precisely specify target stream(s) consistently with
  883. other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
  884. libvorbis sets the codec for the first audio stream and -c copy copies all
  885. the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
  886. aliases to -c:v/a/s
  887. * It is now possible to precisely specify which stream should an AVOption
  888. apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
  889. -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
  890. syntax is deprecated and will stop working soon.
  891. * -map_chapters now takes only an input file index and applies to the next
  892. output file. This is consistent with how all the other options work.
  893. * -map_metadata now takes only an input metadata specifier and applies to
  894. the next output file. Output metadata specifier is now part of the option
  895. name, similarly to the AVOptions/map/codec feature above.
  896. * -metadata can now be used to set metadata on streams and chapters, e.g.
  897. -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
  898. This made -vlang/-alang/-slang options redundant, so they were removed.
  899. * -qscale option now uses stream specifiers and applies to all streams, not
  900. just video. I.e. plain -qscale number would now apply to all streams. To get
  901. the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
  902. and -aq is now an alias for -q:a.
  903. * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
  904. uses stream specifiers. Use -bsf:v/a/s instead of the old options.
  905. * -itsscale option now uses stream specifiers, so its argument is only the
  906. scale parameter.
  907. * -intra option was removed, use -g 0 for the same effect.
  908. * -psnr option was removed, use -flags +psnr for the same effect.
  909. * -vf option is now an alias to the new -filter option, which uses stream specifiers.
  910. * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
  911. * -vtag/-atag/-stag options are now aliases to the new -tag option.
