Use intel integrated video card to accelerate videos

Hi,
is it possible to use the intel video card integrated in the i7-6700hq cpu to hardware accelerate via va-api videos while keeping the discrete nvidia card always active as a primary card?

Re: Use intel integrated video card to accelerate videos

Afaik you will have to force a program to run on the intel card instead of the nvidia one.

Post  

DRI_PRIME=1 glxinfo -B

If that shows intel or modesetting as renderer, prepending DRI_PRIME=1 to the command for the program.

Re: Use intel integrated video card to accelerate videos

Not what I expected, output of

$ xrandr --listproviders
$ glxinfo -B

Re: Use intel integrated video card to accelerate videos

So your X does see both cards, but it seems dri_prime autosetup doesn't work .

Try (and post)

$ xrandr --setprovideroffloadsink 1 0
$ DRI_PRIME=1 glxinfo -B

P.S. please use code tags for such outputs, see https://bbs.archlinux.org/help.php#bbcode

I've followed this wiki page https://wiki.archlinux.org/index.php/NV … phics_only so that to use only NVIDIA card which is what I want, but now I would like to use the unused intel card for the specific task of accelerating videos playing in particular using vlc.

Do you still need me to execute the above commands?

Re: Use intel integrated video card to accelerate videos

That setup should allow the intel card to be used.

"xrandr --setprovideroffloadsink 1 0" tells the intel card it should render stuff and then send it to the nvidia card.
The nvidia card then sends the output to the attached screen(s) .

Xorg was recently changed to allow Opensource drivers to use DRI 3 to automatically make the necessary connections.

Try those 2 commands together, if they don't show modesetting as renderer your current X configuration setup requires changes to allow the use of the intel card.

Re: Use intel integrated video card to accelerate videos

Damn, should have looked better at xrandr --listproviders output .

xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x1b8 cap: 0x1, Source Output crtcs: 0 outputs: 0 associated providers: 1 name:NVIDIA-0
Provider 1: id: 0x1df cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 4 associated providers: 1 name:modesetting

What I was testing requires the nvidia card to function as a Sink Offload which it can't do.

If you want to have both intel and nvidia functional, you'll have to use one of  he methods where the intel card is the primary one and the nvidia card is used on demand only .

Re: Use intel integrated video card to accelerate videos

I understand, but at least in the past those methods have never given me great satisfaction. I hope they have improved in the meantime.
