The problem is that the language information is stored in the metadata of the blu-ray, not the contents of the stream itself (same as with DVDs).

To get it added, I'd have to do some kind of muxing with the output stream (m2ts) into another container, most likely mkv.

I haven't looked into the possibility of doing that yet. I did try with ffmpeg / lavc but didn't get very far at all. Using libmatroska would make more sense.
