capture: yadif deint=1 so progressive SDI passes through unchanged

Browse source 
Bug: yadif=mode=1 unconditionally doubled output framerate for SDI input. On 1080p29.97 progressive sources the encoder produced zero frames (time advanced, size stayed at 1KiB MOV header).

Fix: deint=1 makes yadif only process frames flagged as interlaced; progressive frames pass through at the source rate.
