Hi again, As continuation to the above, doing: gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=7408,height=5556 ! autovideosink sync=false fails but does not crash the kernel. OTOH good old: v4l2-ctl --stream-mmap --stream-to=/dev/null inevitably kills it. Does anyone know WTF is going on this good old i.MX8MM platform? thanks, Petko
