Parameters

plane

Returns

int QtAV::Frame::planeCount

(

)

const

planeCount a decoded frame can be packed and planar.

packed format has only 1 plane, while planar format has more than 1 plane. For audio, the number plane equals channel count. For video, rgb is 1 plane, yuv420p is 3 plane, p means planar

Parameters

plane

default is the first plane

Returns

void QtAV::Frame::setBits	(	uchar *	b,
		int	plane = 0
	)

setBits does nothing if plane is invalid.

if given array size is greater than planeCount(), only planeCount() elements is used

Parameters

b	slice
plane	color/audio channel
