[mythtv] One more FilterManager integration question

[Andrew Mahone]

FilterManager supports more than one frame format for filtering.  Looking at 
NuppelVideoPlayer, it looks like video from a file is assumed to be YV12, and 
video output is assumed to be YV12.  It also looks like NuppelVideoRecorder 
always passes YV12 frame data to the video encoder.  Is my understanding 
correct?  If so, I can just set up NuppelVideoPlayer to initialize filter 
chains for YV12->YV12, and NuppelVideoRecorder to initialize with YV12 output 
and filter-selected input.
