Hi, nvteam:
When I debug my camera , I somtimes use gst-launch-1.0 to show the video.just link below
gst-launch-1.0 -ev v4l2src device=/dev/video0 ! rawvideoparse format=4 width=1920 height=1080 ! videoconvert ! fpsdisplaysink video-sink=xvimagesink sync=false
gst-launch-1.0 -ev v4l2src device=/dev/video1 ! rawvideoparse format=4 width=1920 height=1080 ! videoconvert ! fpsdisplaysink video-sink=xvimagesink sync=false
gst-launch-1.0 -ev v4l2src device=/dev/video2! rawvideoparse format=4 width=1920 height=1080 ! videoconvert ! fpsdisplaysink video-sink=xvimagesink sync=false
but if the video display for long time ,maybe 10mins or 20mins, it freeze. the fps low to 2,3
( I mean when you run the cmd, it can get the right video, but get error after 10 or 20mins)
I can’t close the gst-launch-1.0 with Ctrl +C, or kill cmd.
the dmesg show follow

so what the matter about this issus? is it the bug of system or my camera driver? how to debug?
