General system Applications

Its been a week since i don’t have AMD encoder anymore,
im not a developer and my english has it limite but when i read that : https://aur.archlinux.org/packages/obs-studio-amf it seem the guy managing that package just stoped ?
So how can i have AV1 hardware back ? :frowning:

thanks in advance :slight_smile:

There is a link in the package maintainer’s comment:

Default ffmpeg initial buffer fullness (75%) is too low and results in significantly lower video quality on AMD cards.

Changing it to 100% fixes the quality and also matches what AMF encoder is doing.

Looks like the proposed change has already been merged into the code.

i still dont have any AMD encoder, VAAPI can’t av1 hardware either. For my rx 7900 xt its a lose since the strenght of this gpu is to be able to AV1 hardware :frowning:

Did you install libva-mesa-driver?

According to the wiki VAAPI can AV1 with that.

5

yes already have

yeah i re-installed it but no avi from vaapi (av1) for hardware
from this : https://wiki.archlinux.org/title/Hardware_video_acceleration#Verification:~:text=VA-API.-,Verifying%20VDPAU,-Install%20vdpauinfo%20to

Decoder capabilities:

AV1_MAIN — not supported —
AV1_HIGH — not supported —
AV1_PROFESSIONAL — not supported —

You are checking VDPAU, but we need to check VAAPI.

Install libva-utils and run vainfo. Check for every “AV1” string entry and if it has VAEntrypointEncSlice behind it. See the arch wiki.

Preferably, post the output of the command here.

AV1 support seems to be there.

I have one last thing you could try. In the AUR there is obs-vaapi. Other than that I’m out of ideas. Sorry.

thanks a lot of new encoder just pop !
ill try them and update latter
Edit : still no AVI yet
Edit : https://github.com/fzwoch/obs-vaapi/issues/6
"
AV1 support requires up-stream merge of the AV1 encoder element:

Currently scheduled for GStreamer 1.24 inclusion."

i currently use the 1.22.7

OBS does not support AV1 via VA-API. There’s a merge request for it: https://github.com/obsproject/obs-studio/pull/8832

Afaik OBS Linux AV1 is implemented for Intel’s Arc GPUs via QSV at the moment only.
