9- ffmpeg deprecated, added avconv, which is almost the same for now, except
10for a few incompatible changes in the options, which will hopefully make them
11easier to use. The changes are:
12 * -newvideo/-newaudio/-newsubtitle are gone, because they were redundant and
13 worked in a nonstandard way. -map is sufficient to add streams to output
14 files.
15 * -map now has slightly different and more powerful syntax.
16 + it's possible to specify stream type. E.g. -map 0:a:2 means 'third
17 audio stream'.
18 + omitting the stream index now maps all the streams of the given
19 type, not just the first. E.g. -map 0:s maps all the subtitle streams.
20 + colons (':') are used to separate file index/stream type/stream
21 index. Comma (',') is used to separate the sync stream. This is done
22 for consistency with other options.
23 + since -map can now match multiple streams, negative mappings were
24 introduced. Negative mappings disable some streams from an already
25 defined map. E.g. '-map 0 -map -0:a:1' means 'map everything except
26 for the second audio stream'.
27 * -vcodec/-acodec/-scodec are replaced by -c (or -codec), which
28 allows to precisely specify target stream(s) consistently with other
29 options. E.g. '-c:v libx264' sets the codec for all video streams,
30 '-c:a:0 libvorbis' sets the codec for the first audio stream and '-c
31 copy' copies all the streams.
32 * It is now possible to precisely specify which stream should an AVOption
33 apply to. See the manual for detailed explanation.
34 * -map_chapters now takes only an input file index and applies to the next
35 output file. This is consistent with how all the other options work.
36 * -map_metadata now takes only an input metadata specifier and applies to
37 the next output file. Output metadata specifier is now part of the option
38 name, similarly to the AVOptions/map/codec feature above.
39 * Presets in avconv are disabled, because only libx264 used them and
40 presets for libx264 can now be specified using a private option
41 '-preset <presetname>'.
ddf5ef02 42 * -intra option was removed, it's equivalent to -g 0.
