RockPi4 SE - GPU drivers / configuration

#1

Hi,

for our project I need to work around the hardware video acceleration and gpu for gstreamer and udpsink.

I have installed glmarks. After I run it, I get following error message:

radxa@rock-4se:~$ glmark2
libGL error: failed to create dri screen
libGL error: failed to load driver: rockchip

I would really appreciate it if someone can tell me if this message is ok. Or are the drivers for GPU drivers not installed or configured correctly?

Regards,
Rami

I dunno about stream or stuff but if u need an OS with installed GPU driver for Rock Pi 4 SE, i suggest Twister OS
It make for Rock pi 4B but our board work fine. I dunno if it help but good luck
Follow this tutorial to fix itss boot problem first

Hi chay,

thanks for the replay.

I took lot of time and effort to develop our firmware for this project on RockPi4 SE Debian 11. We are already using gstreamer for capturing the video signal. We are using some gstreamer elements for another tasks, like encoding, threading etc. What we want to do now is to draw some text and images on the video signal via the gstreamer GPU element “gloverlay”, before we broadcast the signal via udpsink.

My question is how to do this kind of drawing with gstreamer via GPU? which drivers should I have installed, to get it worked in our firmware?

Thanks,
Rami

Hi Rami,

I apologize, but I’m just a regular user. I haven’t tried those things yet.
Search “gloverlay” in this forum (all board) and your anwser is the only result so i guess u won’t find any help here.

Anyway, gud luck with what u’re doing.
