Problem with IPU : Rotation by 90 and 270 degree

We are using i.MX6 SabreSD Dual board.

We are trying to perform captured frames using IPU.

We are working on resolutions 720p and 1080p.

We tried both capture(V4L2_CID_MXC_ROT) and display(V4L2_CID_ROTATE) IOCTLs for rotation. But rotation is only possible for 180 and 0 degree.


Where as we are getting below error while doing rotation of 90 and 270 degrees.

mxc_v4l2_output mxc_v4l2_output.0: display work fail ret = -22.


we observed that IPU rotation(90 and 270 degree) works fine for VGA resolution but not for 720p and 1080p.

Can you please suggest any possible approach?
