Optimized surface sharing between gstreamer(-vaapi) and a openGL-application on INTEL ATOM GPUs?

[Sebastian Stelmasik]

Hi there!

We are developing a Digital Signage application on basis of 
gstreamer(-vaapi) and info-beamer (https://info-beamer.com/opensource). 
Until now we were using (cheap) AMD devices where we use glx-pixmaps for 
surface sharing between gstreamer and info-beamer which works quite 
perfect (no mem copy at all).

Now we have to switch to INTEL devices as there are no cheap (and 
compatible with the former open souce driver) AMD devices and now we are 
expiriencing framedrop issues in surface sharing between 
gstreamer(-vaapi) and info-beamer on INTEL ATOM Z8300 devices (which 
should be a lot faster than the AMD E-350 we have been using before). As 
I said before we use glx-pixmaps for surface sharing which works perfect 
on AMD-GPUs. But now there seems to be a lot of in mem copy which couses 
a lot of framedrops.

Is there a optimized way/pipeline for INTEL ATOM GPUs?

Or any other issue we didn't think about while switching from AMD to 
INTEL GPUs?

Best regards and thanks in advance!
