libgstopengl seems to result in illegal operation

Postby freaxtux » Sat Apr 10, 2021 6:57 am

Platform: Raspberry Pi Zero W

`gst-inspection-1.0 /usr/lib/gstreamer-1.0/libgstopengl.so` ends up with `Illegal operation (core dumped)`.
Along with `GST_DEBUG=4`, the last debug message it shows before the error is `initialized GStreamer successfully`.
`gst-inspection-1.0 -b` shows only libgstopengl.so

I don't think I installed wrong package or binary.
Traceback with the dumped core shows libgobject-2.0 and libglib-2.0 listed.
Both are from glib2 package, but reinstalling glib2 did not improve the situation.
`readelf` on each library file shows armv6l

It doesn't seem to be the fault of OpenGL, either.
It happens regardless of enabling vc4-(f)kms-v3d dtoverlay.
I have confirmed glxgears executes without error like that
and could apply hardware acceleration in another app as well. (qv4l2)
