IMX8 reports an error when driving cameras with MIPI interfaces of different resolutions

The IMX8MQ chip uses kernel4.14.98 kernel to drive OV5640 (camera test resolution is 640x480@30fps, data format is YUV422, and arrangement is YUYV), so that the camera MIPI-CSI interface can be pushed to the network port and pulled through VLC on the PC. Now we want to change the MIPI interface camera to OX08B+ISP, IMX8 to realize the reception of the data stream, the camera resolution is 3840x2160@30fps, the data format is YUV422, the arrangement is YUYV, and the camera has been pushing the stream, the ISP has processed the IIC, what do we need to modify?

The instructions are as follows:

GST_DEBUG=4 ./test-launch.out "( v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=3840,height=2160 ! videoconvert ! video/x-raw,format=I420! x264enc tune=zerolatency threads=4 ! rtph264pay pt=96 name=pay0 )"

Hello,

You better try on 6.6.36 kernel since 4.14 has seems with some issue with YUV422.
