Hello! 
minitube-1.8 plays sound, but no video, only black screen with text (video title and description). I tried to open video file that minitube created in /tmp/minitube-273508942-yuga with vlc and it worked, I got sound and video. So, why minitube won't play video and how could I solve this problem? Here is the whole output:
