Mac Video Capture: Connect discard-late-frames in QTKit and AVFoundation
QTKit QTCaptureDecompressedVideoOutput automaticallyDropsLateVideoFrames
is by default NO, should be YES.
AVFoundation has a similar AVCaptureVideoDataOutput with a property
alwaysDiscardsLateVideoFrames that is allegedly YES, this CL forces
it to YES just in case.
