Hi,
I downloaded the AroundView sample v4l2 application from the AGL repository. I added qlibhomescreen and qlibwindowmanager support for it.
Sources were built with agl imx8mqevk built toolchain creating a widget
While testing the widget on the imx8mqevk target , I am facing an unknown pixel format:'XR24' run time issue. I tested it with the NXP MIPI CSI-2 camera and USB web cameras connected to imx8mqevk board but it was showing the same pixel format error on both the cameras.
I used the v4l2-ctl -d /dev/video2 --all command and identified the camera info and pixel format.
USB cam info :

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'
Jul 30 09:51:32 imx8mqevk kernel: mx6s-csi 30a90000.csi1_bridge: Fourcc format (0x32315559) invalid.

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