Is there a way to display multiple subtitles at the same time? It would help a lot while learning a new language. I have some *.mkv movie with two embedded subtitles, how would I turn them both on, so that one will be on the bottom and another one on the top? Or at least a fast switch with immediate text update without rewinding back would be nice.
I spent a few days googling about this topic. The short answer is that there is no way to play two subtitle tracks in a *.mkv file simultaneously, in Ubuntu.
There are, however:
The best you can do with your .mkv files is to extract one subtitle from .mkv file and put it in a separate subtitle file, so that you can take advantage of the vlc extension.
Alternatively you can consider KMplayer for Microsoft Windows. I never tried it, because I don't have a Windows, but apparently it is what always comes out top if you google for dual subtitle players.
