◆ ComputeFittedRect()

static sRect ComputeFittedRect	(	AVFrame *	frame,
		uint64_t	dispX,

		uint64_t	dispWidth,
		uint64_t	dispHeight
	)

static

Fits the video frame into a given area.

Parameters

frame	AVFrame with frame dimensions and aspect ratio information
dispX	x offset of video area
dispY	y offset of video area
dispWidth	width of video area
dispHeight	height of video area

Returns: the new computed video area or the given area if no frame was given
