Hello Community
We met a problem about imx6 IPU as bellow.
Data path =
imx6 BT 656 capture input, crop size = 720 x 480, capture format = 720 x 480, 60fps progressive
then,
do memory copy to output buffer,
then,
imx6 V4L2 output scaling on /dev/video17, format = 720x480, output cropsize = 1280 x 720, 60fps progressive, output dot clock frequency = 59.03MHz
then we found out that the display image is NG, and the right-most edge area is lost.
We did another test like this:
imx6 BT 656 capture input, crop size = 720 x 480, capture format = 720 x 480, 60fps progressive
then,
do memory copy to output buffer,
then,
imx6 V4L2 output scaling on /dev/video17, format = 720x480, output cropsize = 1080 x 720, 60fps progressive, output dot clock frequency = 59.03MHz
then we found out that the display image occupies the left part of the display area as expected(because the display area is 1280x720), and the right-most edge area is NOT lost.
Is it because of some kind of limitation in IMX6solo IPU capability? How can we overcome this effect?
