App Run Fails With Errors

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

The “v4l2-ctl” has told you your camera can only output ‘UYVY’ or ‘GRAY8’ format. Why did you set “YUY2” caps?

Please add videoconvert before nvvideoconvert to convert UYVY to any supported format.


sudo GST_DEBUG=3 gst-launch-1.0 v4l2src device=/dev/video2 ! 'video/x-raw, format=UYVY, width=640, height=480, framerate=30/1'  !  videoconvert ! 'video/x-raw, format=I420' ! nvvideoconvert !
