  855. version 0.9:

  856. 

  857. - openal input device added

  858. - boxblur filter added

  859. - BWF muxer

  860. - Flash Screen Video 2 decoder

  861. - lavfi input device added

  862. - added avconv, which is almost the same for now, except

  863. for a few incompatible changes in the options, which will hopefully make them

  864. easier to use. The changes are:

  865.     * The options placement is now strictly enforced! While in theory the

  866.       options for ffmpeg should be given in [input options] -i INPUT [output

  867.       options] OUTPUT order, in practice it was possible to give output options

  868.       before the -i and it mostly worked. Except when it didn't - the behavior was

  869.       a bit inconsistent. In avconv, it is not possible to mix input and output

  870.       options. All non-global options are reset after an input or output filename.

  871.     * All per-file options are now truly per-file - they apply only to the next

  872.       input or output file and specifying different values for different files

  873.       will now work properly (notably -ss and -t options).

  874.     * All per-stream options are now truly per-stream - it is possible to

  875.       specify which stream(s) should a given option apply to. See the Stream

  876.       specifiers section in the avconv manual for details.

  877.     * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the

  878.       sense that they're specified after the output filename instead of before,

  879.       like all other options. In avconv this irregularity is removed, all options

  880.       apply to the next input or output file.

  881.     * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they

  882.       irregular and highly confusing, they were also redundant. In avconv the -map

  883.       option will create new streams in the output file and map input streams to

  884.       them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for

  885.       each stream in the first input file.

  886.     * The -map option now has slightly different and more powerful syntax:

  887.         + Colons (':') are used to separate file index/stream type/stream index

  888.           instead of dots. Comma (',') is used to separate the sync stream instead

  889.           of colon.. This is done for consistency with other options.

  890.         + It's possible to specify stream type. E.g. -map 0:a:2 creates an

  891.           output stream from the third input audio stream.

  892.         + Omitting the stream index now maps all the streams of the given type,

  893.           not just the first. E.g. -map 0:s creates output streams for all the

  894.           subtitle streams in the first input file.

  895.         + Since -map can now match multiple streams, negative mappings were

  896.           introduced. Negative mappings disable some streams from an already

  897.           defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for

  898.           all the stream in the first input file, except for the second audio

  899.           stream'.

  900.     * There is a new option -c (or -codec) for choosing the decoder/encoder to

  901.       use, which makes it possible to precisely specify target stream(s) consistently with

  902.       other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0

  903.       libvorbis sets the codec for the first audio stream and -c copy copies all

  904.       the streams without reencoding. Old -vcodec/-acodec/-scodec options are now

  905.       aliases to -c:v/a/s

  906.     * It is now possible to precisely specify which stream should an AVOption

  907.       apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while

  908.       -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k

  909.       syntax is deprecated and will stop working soon.

  910.     * -map_chapters now takes only an input file index and applies to the next

  911.       output file. This is consistent with how all the other options work.

  912.     * -map_metadata now takes only an input metadata specifier and applies to

  913.       the next output file. Output metadata specifier is now part of the option

  914.       name, similarly to the AVOptions/map/codec feature above.

  915.     * -metadata can now be used to set metadata on streams and chapters, e.g.

  916.       -metadata:s:1 language=eng sets the language of the first stream to 'eng'.

  917.       This made -vlang/-alang/-slang options redundant, so they were removed.

  918.     * -qscale option now uses stream specifiers and applies to all streams, not

  919.       just video. I.e. plain -qscale number would now apply to all streams. To get

  920.       the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale

  921.       and -aq is now an alias for -q:a.
