imxg2dvideosink crashes on IMX8MM after "framebuffer physical address is not available"

[Talkless]

I've reported bug against GStreamer about VSYNC tearing on IMX8MM (https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/1006) and wanted to try out sink from gstreamer-imx as an alternative, but this simple pipeline just crashes:

# env GST_DEBUG="imx*:5" ./gst-launch-1.0 -v videotestsrc pattern=blink ! video/x-raw,width=1280,height=720 ! imxg2dvideosink

Also, I don't see imxipuvideosink mentioned here and there available for me, maybe some build configuration is inadequate?

The crash is a bug. It should exit cleanly with an error message.

But, look at the README:

NOTE: 2D blitter video sink elements do not work on i.MX8 machines, since these no longer use the older MXC framebuffer driver (which these video sink elements rely on).

Use kmssink, waylandsink, or glimagesink instead. If tearing happens with glimagesink, try it inside Weston, or try waylandsink.
