It did minor testing today and didn’t notice anything abnormal aside from 
ffplay complaining quite verbosely about buffer overruns when opening directly 
with ffplay. Otherwise, there is a small reduction in overhead, and the video 
is smoother when reducing the output framerate to half that of the input. (60 
to 30 in my case)
