Answers.Text: Using `apt`, it seems to be `libmatroska-dev` instead of `libmatroska`. I know it's not an issue, I just wanted to know the name of the packages. Does VLC need other packages for MKV appart from this one?

Answers.Text: I found `libebml` is required by `libmatroska`. But there may be other packages requred to play MKV. MKV is basically a container, so obviously demuxer for audio and video codecs like mpeg, flac, ogg is required.  Again it need to Qt to draw the windows to display your MKV, so you may call it a dependency. Then comes PulseAudio/JACK to play sound. So your question is quite tricky.
