Dear all,
I observes libcamera3 support MJPG format for UVC camera on Android 7.1.1.
After trying to enable configUseMJPG and use 5M USB camera for test on imx6q sabresd platform, I got different results when capturing different resolution pictures.
5M USB camera resolution support as below:

Thanks for any help.
