Question on VideoFormatControl.DFC_ constants...
Am I mistaken in thinking there's no difference between DFC_PROCESSING_FULL and DFC_PROCESSING_LB_16_9 when the input is 16:9 and the output is 4:3? Seems like they'd both result in 16x9 letterbox - black bars on top & bottom.
Some diagrams illustrating the expected effect of all the DFC constants in various scenarios would be extremely helpful. Barring that, I'm hoping for some more info here.
