I don't have another pc to test these, and my ubuntu VM which I tried to
config runs so slow its unusable. also, ffmpeg was removed for Ubuntu 14.04
and for the last 1 hour I've tried installing it from different tutorials with
no luck. Isn't there a more out-of-the-box method to test video recording?
