For i.MX8MQ:

~# gst-launch-1.0 v4l2src io-mode=3 device=/dev/video0 ! video/x-raw,width=1280,height=720 ! waylandsink

or

~# gst-launch-1.0 v4l2src io-mode=3 device=/dev/video0 ! video/x-raw,width=1280,height=720 ! kmssink

For i.MX8MM:

~# gst-launch-1.0 v4l2src io-mode=2 device=/dev/video0 ! video/x-raw,width=1920,height=1080 ! glimagesink

or

~# gst-launch-1.0 v4l2src io-mode=2 device=/dev/video0 ! video/x-raw,width=1920,height=1080 ! waylandsink window-width=1280 window-height=720

Note:

The parameter width=1280 window-height=720 for waylandsink corresponds to the display resolution.

It has to use Yocto with xwayland backend. wayland backend can't display properly. It only shows green on display.

It's known issue in Yocto 2.5.
