ff_fmt_from_frame()

SwsFormat ff_fmt_from_frame	(	const AVFrame *	frame,
		int	field
	)

This function also sanitizes and strips the input data, removing irrelevant fields for certain formats.

Calculate largest value from histogram to use as fallback for clips with missing MaxSCL information. Note that this may end up picking the "reserved" value at the 5% percentile, which in practice appears to track the brightest pixel in the scene.
