from your earlier log, it seems the gldisplaygbm is not

<br>
Step 1 is to figure out why.<br>
<br>
Try getting some more debug logs from the gbm detection
with:<br>
<br>
GST_DEBUG=gldisplay:7,<wbr>gleglgbm:7,gl*:4,3
gst-launch-1.0 <pipeline><br>

This should show what's detected and what fails for you.<br>

Random side guess. Are you running on a dual-GPU
system?<br>

We support

Some other
