Deallocate texture in FLUSH_START
I've been playing a video, just before it gets to the end it freezes and I get the output below.
For now I haven't managed to make some minimal code to reproduce it yet, so just wondering it is known - similar to the OMX bug mentioned earier ?

If you're using master, then you're using gst-plugins-bad almost for sure.
Anyway, it doesn't really mind, as none of the two versions seem to listen to
the FLUSH_START event.

My suggestion would be to focus on FLUSH_START instead of reacting in the
error state. In my experience, when "Insufficient resources" happens, it's too
late to revert to a working state again.
So, what I would do would be to touch gst_glimage_sink_event()[1], adding a
case for FLUSH_START. There you could do the same as the DRAIN query does[2]
(copy-paste or refactor into a common function called from both places). Make
sure that you don't return inside the case, so the code flow continues and
ends up calling to the ancestor class method to process the event[3]. That
last part is important for the right operation of the element.

I haven't looked in deep how dispmanx-gst-play works, so I can't give an
opinion about why things work there. Maybe a different sink is used (one which
doesn't hold EGL buffers for itself on flush), I don't know.
Another think I forgot: check that your Raspberry has enough graphics memory
configured. Assuming you're using raspbian: sudo raspi-config, advanced
options, memory split. Use some higher value such as 128.
In any case, I hope the suggestions help you to fix the issue. :-)
Cheers.
