You might want to take a look at vgtmpeg:


It's a fork of ffmpeg that can read DVDs (or VIDEO_TS directory 
structures) directly.  If I remember correctly, it can identify the 
language for audio/subtitle streams by reading the .IFO files.

I haven't looked at it in quite a while because it was always out-of-date 
with respect the ffmpeg source.  It appears it's been updated to the 4.0 
branch now, but that was last year, so it's still quite out-of-date.  So 
while you may gain the ability to identify the language for audio/subtitle 
streams you may be missing ffmpeg fixes/features that you need or want.
