Hi,

Cloudtech reported i.MX6Q V4L2 IOCT- IPU_ROTATE_HORIZ_FLIP  can't work. Can you help to check?

imx6q  android 4.2.2平台上用adv7180  camera 由于拍照方向水平镜像了需要用到ipu 来实现 H mirror, 通过
V4L2  IOCTL
调用但目前case V4L2_CID_MXC_ROT:中的IPU_ROTATE_HORIZ_FLIP 不起作用,但IPU_ROTATE_VERT_FLIP这个垂直镜像可以。

Hi Linda, for IPU display channel, it can only support IPU_ROTATE_VERT_FLIP(vertical filp), for other kind of rotation, the customer should use IPU task to implement it.

Only one FLIP can work at the same time, so IPU_ROTATE_HORIZ_FLIP + IPU_ROTATE_VERT_FLIP can't work.
