vdpauinfo on irisXE
Hello guys, I have installed arch and I am exploring the system. I have a t14 lenovo laptop with i5-1145g7 with irisXE graphics, and I installed mesa. intel-media-driver and libva-vdpau-driver-vp9-git as per arch wiki to enable hw video decode.
issuing grep -iE 'vdpau | dri driver' ~/.local/share/xorg/Xorg.0.log, I get:
[ 10.129] (II) modeset(0): [DRI2] DRI driver: iris
[ 10.129] (II) modeset(0): [DRI2] VDPAU driver: va_glfirst question, shouldn't my driver be iHD there? or is iris expected?
also when running vdpauinfo, i get:
display: :0 screen: 0

, I see that the list of supported decoder capabilites is short, is this expected on this chip and the drivers I am using? it looks weird to me.

Re: vdpauinfo on irisXE
vdpau is designed by nvidia and works best on nvidia drivers. Intel does nothing with vdpau and uses VA-API .
The libva-vdpau-driver-vp9-git translates va-api calls to VDPAU calls and can be useful if your hardware supports vdpau but your appiication(s) don't .
Post the output of vainfo to verify which capabilities your intel gpu has.
Which application(s) are you trying to run with HW video acceleration ?
Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: vdpauinfo on irisXE
issuing grep -iE 'vdpau | dri driver' ~/.local/share/xorg/Xorg.0.log, I get:
[ 10.129] (II) modeset(0): [DRI2] DRI driver: iris
[ 10.129] (II) modeset(0): [DRI2] VDPAU driver: va_glfirst question, shouldn't my driver be iHD there? or is iris expected?
(Forgot to answer) .
The IHD functions on a different levle and would be shown as libva driver .
Iris is the most used intel mesa dri driver atm, older intel video uses crocus .
Your procesor i5-1145g7 is from the Tiger Lake family which is mentioned on https://en.wikipedia.org/wiki/VP9#Hardw … mentations .
So there is hardware support for vp9 on your system , the problem lies in software support.
The vainfo does list VAProfileAV1Profile0 and AV1 is the successor of vp9 . (vp10 was never releaxsed, but it's functionality was added to av1 )
Does youtube support AV1 ?

I am not sure about the support for av1 on yt haven't checked. but I am seeing that chromium hw accell is pretty much hit or miss these days
