Hi,
I downloaded the AroundView sample v4l2 application from the AGL repository. I added qlibhomescreen and qlibwindowmanager support for that. I was successfully compiled and created the widget using the 8.99.5 AGL imx8mqevk toolchain.

While testing the widget on the imx8mqevk target and I am facing unknown pixel format:'XR24' run time issue. I tested the NXP MIPI CSI-2 camera and USB web camera but it was showing the same pixel format error on both the camera.

I used the v4l2-ctl -d /dev/video2 --all​ command and identified the camera info and pixel format.

I changed the pixel format to 'YUYV' in the source based on the above info. But that also not
accepting and throwing following errors,

Jul 30 09:51:32 imx8mqevk kernel: unknown pixelformat:'YUYV'

For more details please see the following jornalctl logs and help me with how to solve the issues.
