obs-ffmpeg: fix crash with rawvideo

Browse Source 
Some codecs have no recommended pix_fmts so we must check that pix_fmts
is not null before trying to find a good match. This just prays whatever
OBS is configure for is a valid format when users choose these oddball
codecs. When its not you should get a normal recording fail instead of a
crash now.

fixes #3031
