Hi Francesco,
I reproduce and resolve your issue on AGL koi.
Let me know if this solution is OK for you.
1) reproduce the issue
wget
https://test-videos.co.uk/vids/bigbuckbunny/mp4/h264/360/Big_Buck_Bunny_360_10s_20MB.mp4
scp ./Big_Buck_Bunny_360_10s_20MB.mp4 h3:/media
ssh h3
su - agl-driver
export XDG_RUNTIME_DIR=/run/user/1001
gst-launch-1.0 filesrc location=/media/Big_Buck_Bunny_360_10s_20MB.mp4 !
qtdemux ! queue ! h264parse ! omxh264dec ! waylandsink
etting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.

If it is not your issue, do not hesitate to send me your command line to
reproduce it.
2) solve the issue in command line
ssh h3
chsmack -a '*' /dev/rgnmm
chsmack -a '*' /dev/uvcs
chsmack -a '*' /dev/rgnmmbuf
chsmack -a '*' /dev/vspm_if
chmod 0666 /dev/rgnmm
chmod 0666 /dev/uvcs
chmod 0666 /dev/rgnmmbuf
chmod 0666 /dev/vspm_if
usermod -a -G display agl-driver
su - agl-driver
export XDG_RUNTIME_DIR=/run/user/1001
gst-launch-1.0 filesrc location=/media/Big_Buck_Bunny_360_10s_20MB.mp4 !
qtdemux ! queue ! h264parse ! omxh264dec ! waylandsink
3) solve with udev
vi /etc/udev/rules.d/73-gst.rules
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}="*"
(reboot)
ssh h3
su - agl-driver
export XDG_RUNTIME_DIR=/run/user/1001
gst-launch-1.0 filesrc location=/media/Big_Buck_Bunny_360_10s_20MB.mp4 !
qtdemux ! queue ! h264parse ! omxh264dec ! waylandsink
If this is not a solution for you, let me know.
This have been tested on the last AGL KOI.

Hi everyone,
I have some updates regarding the issue posted some time ago. Currently,
when an application runs as *agl-driver user* tries to use *hardware
acceleration* by OMX library.
I get the same error:

Error: "GStreamer encountered a general supporting library error." |
So if you try to run a GStreamer pipeline under *root* user the system
works (also it works fine under /Weston-start/), then the CPU
consumption is under 60%.
Despite this, Now, I want access to consumes GStreamer-omx remaining
agl-driver user thus each application which wants access to
GStreamer-omx (acceleration hardware) is able to preserve the normal
functionality (agl-compositor, pipewire, smack, binder, etc.) Any advice
or suggestion is welcome.
Best regards, Francesco
