 |
|
I am trying to extract subtitles from a file with ffmpeg. For some reason that I don't understand, I can only extract the first subtitle stream.
| Code: |
$ mediainfo /path/to/some/file
[...]

First set of subtitles, no problem:
| Code: |

But any other set of subtitles gets me this:
| Code: |
$ ffmpeg -i /path/to/some/file -an -vn -c:s:1 srt sub1.srt
[...] (identical to above)
Stream mapping:
Stream #0:2 -> #0:0 (subrip -> ?)

I am probably doing something wrong, but I can't figure out exact what. :)

Do these work?
| Code: |
$ ffmpeg -i /path/to/some/file -an -vn -c:s:0.2 srt sub2.srt
$ ffmpeg -i /path/to/some/file -an -vn -c:s:0.3 srt sub3.srt
$ ffmpeg -i /path/to/some/file -an -vn -c:s:0.6 srt sub6.srt

No they don't. No matter which stream I ask for, I ALWAYS get the first subtitle stream:

Note that it still uses (even though I asked for 0.6):

Don't know if you are still fighting with this but try this:
| Code: | | $ ffmpeg -i /path/to/some/file -map 0:s:0 -an -vn -c:s srt sub0.srt |
change the 0:s:0 to 0:s:1, etc for other tracks |

By default, ffmpeg selects the first available/suited stream, so you need to specify which one you want (not just which codec you want to use), like:
ffmpeg -i /path/to/some/file -c copy -map 0:s:0 sub0.srt
ffmpeg -i /path/to/some/file -c copy -map 0:s:1 sub1.srt
ffmpeg -i /path/to/some/file -c copy -map 0:s:2 sub2.srt
Cheers...

What is it you plan to do with these extracted subtitles?
A great toolset with/instead of ffmpeg is mkvtoolnix.
