We have designed our application board based on iMX8MQ processor. We have completed bring up of all interfaces including USB3.0 & HDMI port.

Both USB & HDMI interfaces are working fine. We are able to play saved video from USB mass storage drive to HDMI. 

Now while we stream a video from Webcam USB to HDMI port. We are getting a continuous "Green screen" on HDMI 720p display and getting continuous Kernal crash logs on console. We are not able to terminate the Gstremer command using CNTL+C, the power cycle is required to do so. 

See the console logs in the attached file below.


We are using below Gstreamer command:

gst-launch-1.0 v4l2src device=/dev/video2 ! 'video/x-raw,format=YUY2' ! glimagesink
