I'm running this gstreamer pipe
gst-launch -v videotestsrc ! mfw_v4lsink
works fine for several minutes and then just stops displaying anything on the monitor. Once it stops dispalying killing it and restarting won't start the display back up. I have to reboot.
gst-launch does produce any console/dmesg errors and there are no other indicators why it's stopped working.
This is the sabre imx6q based board with the latest ltib release.
