SOLVED: turns out mesa is not enough for this. i also had to install:

mesa-va-gallium mesa-dri-gallium

now we're good!

hi all!

i've hit a wall here and could use your input if you have any thoughts!

i'm running Owncast latest via rootful Podman on a distro with SELinux.

i'm trying to implement hardware acceleration via the server's AMD GPU, but it is not working.

AMD Radeon RX 7600

Kernel: 6.15.4-1-default

i've turned VAAPI on in the web admin settings.

the container comes with ffmpeg 6 and libva.

For SELinux, i've run:

setsebool -P container_use_devices true

In my quadlet i've added:

[Container]

AddDevice=/dev/dri

Exec=apk add mesa

the devices appear rw in the container:

/app # ls -l /dev/dri

total 0

crw-rw---- 1 root 486 226, 0 Jul 9 15:58 card0

crw-rw---- 1 root 489 226, 128 Jul 9 15:58 renderD128

here is the error i'm getting:

time="2025-07-09T15:58:46Z" level=error msg="[AVHWDeviceContext @ 0x7f96891c7cc0] Failed to initialise VAAPI connection: -1 (unknown libva error)."

any help to troubleshoot this would be most appreciated! thank you!

What exact GPU model? Kernel version? Have you tried it with SELinux disabled temporarily?

[–] Nico_198X@europe.pub 3 points 1 week ago (1 children)

thank you, i figured it out!

[–] malwieder@feddit.org 2 points 1 week ago (1 children)

Would be awesome if you'd share your solution for the next person encountering the same issue :)

[–] Nico_198X@europe.pub 2 points 1 week ago

it's all in the edited op!

[–] Nico_198X@europe.pub 1 points 1 week ago

AMD Radeon RX 7600

6.15.4-1-default

i have not tried that. i'll give that a go. i ASSUME it's a selinux permissions issue, but i thought i had that all cleared.

[–] Nico_198X@europe.pub 1 points 1 week ago

so, actually no change even with setting SELinux to Permissive. so i guees it isn't SELinux after all...
