You'll need someone more knowledgeable than I
but I see mis-matched audio sampling rates, and LOTS of errors, even before starting the recording
I'm wondering if ANYTHING was ever recorded.. (and I suspect not)
The whole point of MKV (vs say MP4) if file is created while recording, and am unclean finish still has usable video. If you have no MKV, maybe one wasn't created to start with? if one was created, and it is gone now, you'd need an undelete tool to find it... maybe
