Hi Ronan,
Thank you for your reply and suggestion. I tried solution 3 with udev, it has worked fine.
So, I implemented the recipe directly in my meta-layer adding these two recipes:
agl-dirver_%.bbappend
inherit extrausers EXTRA_USERS_PARAMS = " usermod -a -G display agl-driver;"gst-rules_1.0.bb
SUMMARY = "Configuration files for running GStreamer acceleration hardware" LICENSE = "CLOSED" inherit allarch agl-graphical do_configure[noexec] = "1" do_compile[noexec] = "1" do_install() { # Add a rule to ensure the 'display' user has permissions to # open the graphics device install -d ${D}${sysconfdir}/udev/rules.d cat >${D}${sysconfdir}/udev/rules.d/73-gst.rules <<'EOF' KERNEL=="rgnmm", GROUP="display", MODE="0660", SECLABEL{smack}="*" KERNEL=="uvcs", GROUP="display", MODE="0660", SECLABEL{smack}="*" KERNEL=="rgnmmbuf", GROUP="display", MODE="0660", SECLABEL{smack}="*" KERNEL=="vspm_if", GROUP="display", MODE="0660", SECLABEL{smack}="*" EOF }
The video playback now consumes the acceleration hardware correctly and does not consume excessive CPU resources.
Although it seems to work fine initially, after some time, I detect strange effects on the screen such as blinking, ghost-frame, vertical stripe overlapped to image, etc.
When I change the URI the problem disappears, and the effects before described do not show or it shows immediately as the video starts. (all my videos are in HLS format m3u8 and I've already installed the GStreamer library to support it).

The recurrent problems are:
- close MMD carveout ERROR;
- close MMD kernelheap ERROR;
- QSGRenderThread error;
Furthermore, to reproduce the issues, I share the links consumed in mine pipeline:
- https://di-j16ei4yq.vo.lswcdn.net/sportitalia/sihd.smil/playlist.m3u8
- http://mediapolisvod.rai.it/relinker/relinkerServlet.htm?cont=D4XXmqQcOyRRYkoTUnFyCQeeqqEEqualeeqqEEqual
In QML application I use the following structure:
"gst-pipeline: uri=http://mediapolisvod.rai.it/relinker/relinkerServlet.htm?cont=D4XXmqQcOyRRYkoTUnFyCQeeqqEEqualeeqqEEqual video-sink=qtvideosink audio-sink=\"pipewiresink stream-properties=p,media.role=Multimedia\""
