| version 0.9: |
| |
| - openal input device added |
| - boxblur filter added |
| - BWF muxer |
| - Flash Screen Video 2 decoder |
| - lavfi input device added |
| - 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: |
| * The options placement is now strictly enforced! While in theory the |
| options for ffmpeg should be given in [input options] -i INPUT [output |
| options] OUTPUT order, in practice it was possible to give output options |
| before the -i and it mostly worked. Except when it didn't - the behavior was |
| a bit inconsistent. In avconv, it is not possible to mix input and output |
| options. All non-global options are reset after an input or output filename. |
| * All per-file options are now truly per-file - they apply only to the next |
| input or output file and specifying different values for different files |
| will now work properly (notably -ss and -t options). |
| * All per-stream options are now truly per-stream - it is possible to |
| specify which stream(s) should a given option apply to. See the Stream |
| specifiers section in the avconv manual for details. |
| * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the |
| sense that they're specified after the output filename instead of before, |
| like all other options. In avconv this irregularity is removed, all options |
| apply to the next input or output file. |
| * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they |
| irregular and highly confusing, they were also redundant. In avconv the -map |
| option will create new streams in the output file and map input streams to |
| them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for |
| each stream in the first input file. |
| * The -map option now has slightly different and more powerful syntax: |
| + Colons (':') are used to separate file index/stream type/stream index |
| instead of dots. Comma (',') is used to separate the sync stream instead |
| of colon.. This is done for consistency with other options. |
| + It's possible to specify stream type. E.g. -map 0:a:2 creates an |
| output stream from the third input audio stream. |
| + Omitting the stream index now maps all the streams of the given type, |
| not just the first. E.g. -map 0:s creates output streams for all the |
| subtitle streams in the first input file. |
| + 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 'create output streams for |
| all the stream in the first input file, except for the second audio |
| stream'. |
| * There is a new option -c (or -codec) for choosing the decoder/encoder to |
| use, which makes it possible to precisely specify target stream(s) consistently with |
| other options. E.g. -c:v lib264 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 without reencoding. Old -vcodec/-acodec/-scodec options are now |
| aliases to -c:v/a/s |
| * It is now possible to precisely specify which stream should an AVOption |
| apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while |
| -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k |
| syntax is deprecated and will stop working soon. |
| * -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. |
| * -metadata can now be used to set metadata on streams and chapters, e.g. |
| -metadata:s:1 language=eng sets the language of the first stream to 'eng'. |
| This made -vlang/-alang/-slang options redundant, so they were removed. |
| * -qscale option now uses stream specifiers and applies to all streams, not |
| just video. I.e. plain -qscale number would now apply to all streams. To get |
| the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale |
| and -aq is now an alias for -q:a. |
| * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which |
| uses stream specifiers. Use -bsf:v/a/s instead of the old options. |
| * -itsscale option now uses stream specifiers, so its argument is only the |
| scale parameter. |
| * -intra option was removed, use -g 0 for the same effect. |
| * -psnr option was removed, use -flags +psnr for the same effect. |
| * -vf option is now an alias to the new -filter option, which uses stream specifiers. |
| * -vframes/-aframes/-dframes options are now aliases to the new -frames option. |
| * -vtag/-atag/-stag options are now aliases to the new -tag option. |
