I have a few video files with English audio track and French audio track, because the family wants French and I prefer VO. With ffmpeg I can easily filter all tracks to keep eng and fre, the problem is there are multiple french dialects, one of them being Candian (VFQ).
Therefore, with the following input streams:
Stream #0:1(fre): Audio: eac3, 48000 Hz, 5.1(side), fltp, 768 kb/s (default)
Metadata:
title : E-AC3 VFF
Stream #0:2(fre): Subtitle: subrip (default) (forced)
Metadata:
title : FORCED VFF
Stream #0:3(fre): Audio: ac3, 48000 Hz, 5.1(side), fltp, 384 kb/s
Metadata:
title : AC3 VFQ
Stream #0:4(fre): Subtitle: subrip
Metadata:
title : FORCED VFQ
Stream #0:5(eng): Audio: eac3, 48000 Hz, 5.1(side), fltp, 768 kb/s
Metadata:
title : E-AC3 VO
The command -map 0:v: -map 0:m:language:eng -map 0:m:language:fre
does not filter out anything, and I keep both audio which is wasteful. The only metadata that could be used to filter seems to be the title.
