iMX6 IPU resizing problem

Hi,

I'm trying to use IPU to resizing YUV444 image to a smaller YUV420 image on a iMX6 Sabrelite board.

I'm using sample code from:

The only thing I have changed is the task structure:

	// Output image size and format
	task.output.width = 512;
	task.output.height = 384;
	task.output.format = v4l2_fourcc('I', '4', '2', '0');

Here is the result I got, can anyone tell me what was wrong?

Thanks.

OK, I figured out that the original picture in 444P format, not Y444 format. Now I got correct output.
