Optimising OBS VA-API usage with AMD and Intel GPUs

Hi!

I'm new to Arch, hence my posting here. I installed it last night/this morning with the intention of testing D9VK, a d3d9-->vulkan wrapper made by a friend, for use with Windows games.
I want to screen record it, so I'm trying with OBS, and since I don't have a beastly CPU, I'd like to use GPU accelerated encoding for the stream.
I realised that OBS supports VA-API, and trying it with my AMD card led to significantly degraded performance in games (which wouldn't be good for performance comparisons). I thought I could perhaps use my Intel iGPU, and though it shows up as a VA-API input device, I get an error trying to use it.
I thought I'd installed the relevant drivers, though perhaps I'm wrong.

Curiously, vainfo doesn't seem to show the Intel GPU at all.


For lack of a better means of sharing info, have some screenshots:

Not working (with Intel iGPU):

Error I get in the terminal from OBS with the Intel config:

And in OBS itself:

I hope this is...decent info to work from, and posted in the right place. If you need anything more, please tell me how to provide it.
Advise me, please (:

Re: Optimising OBS VA-API usage with AMD and Intel GPUs

It looks like your card only supports mpeg2?

Thanks for the reply!
At present, perhaps, but it should support what I'm after, according to this:
https://01.org/linuxgraphics/community/vaapi

Most concerning is, I guess, that it's not showing up under vainfo.

Re: Optimising OBS VA-API usage with AMD and Intel GPUs

If I understand correctly it is picking up your AMD card not IntelHD

Re: Optimising OBS VA-API usage with AMD and Intel GPUs

First, don't post huge pictures, see https://wiki.archlinux.org/index.php/Co … s_and_code .

Your system appears to use hybrid graphics / PRIME , how did you set it up ?

post glxinfo -B and xorg log .

I see, apologies.

I didn't notice there were code tags available to me.

glxinfo -B:
http://sprunge.us/ZH2idH

For xorg...I apparently don't have it as an available command. Have I been solely using Wayland without realising? Am I missing something?

[tedster@BlackYeti ~]$ loginctl show-session 2 -p Type
Type=x11

Evidently I am using X server, but I don't know what I'd actually call to get the log you'd want.

In the case it's helpful, here's my Xorg.0.log:
http://sprunge.us/q35VTH

And...in terms of graphics setup, I'm not sure.
I installed the base system, then Budgie and LightDM, then GNOME, and then relevant Vulkan drivers and loaders.
All I've manually touched (apart from telling GRUB to load the correct AMD driver) would be represented in my list of packages, I think.

My grub.cnf:
http://sprunge.us/MTbxn2

When I experienced bad performance, I enabled my iGPU in the BIOS and installed whichever Intel Mesa packages, which should be listed in the list of packages linked above.

Thanks,
Ted

Re: Optimising OBS VA-API usage with AMD and Intel GPUs

THe glxinfo output clearly shows you'rre using the amd videocard, but xorg logs indicate you're using modesetting.

Install xf86-video-amdgpu , reboot or restart X and post fresh xorg logs.
Also post full lpsci -k output please.

One thing to keep in mind :
I'm not looking at OBS or VA-API for now. Your graphics setup is less-then-optimal and we need to get things setup as best as possible first.

Makes sense!

Installed that package; the info you wanted:

Re: Optimising OBS VA-API usage with AMD and Intel GPUs

lspci -k output is as expected, xorg logs look much better.

- You appear to have 3 monitors of the same type but using different connectors : DisplayPort, HDMI and DVI .
Is this intentional ?

- Those monitors are currently setup to form one big virtual screen, is that how you want things ?


[    44.704] (II) event3  - Logitech Gaming Mouse G402: SYN_DROPPED event - some input events have been lost.

Not sure what this means, but if may be a symptom of a problem . It should be looked at some point in a separate thread I think.


Post xrandr --listproviders please.

Post xrandr --listproviders please.

The display setup is as I want it in each case, yes.
For the mouse, it's probably just that the system couldn't keep up with the mouse's update rate at one point.

That xrandr command:

[tedster@BlackYeti ~]$ xrandr --listproviders

Re: Optimising OBS VA-API usage with AMD and Intel GPUs

Not what i hoped to see, especially the libGL errors.

I'm beginning to think the motherboard/firmware/chipset don't support current config very well, but let's look more in-depth for now.
Please post dmesg and/or journalctl -b  .

Alright; I bit the bullet.
In the case it causes issues and I can't downgrade, I figure can just (hopefully) torture the system enough with forcibly failed boots to take me to the backup BIOS.
...it also took me far too long to figure out how to fix my GRUB UEFI setup so I could boot again (:

Regardless of the above, the various options you're asking for:

Re: Optimising OBS VA-API usage with AMD and Intel GPUs

firmware settings appear to be as they should be, the bios update has solved the DMAR issue and the libgl error in
DRI_PRIME=1 glxinfo -B.

I've looked into va-api with multiple cards and found https://askubuntu.com/questions/892726/ … ideo-cards .
That post indicates libva needs to be told which driver to use for the 2nd card.

Your processor is an Intel(R) Core(TM) i5-4670K from the haswell family .
https://github.com/intel/media-driver/ doesn't list haswell as supported, so you have to use libva-intel-driver instead.

Install libva-intel-driver (if not present) , then run

$ DRI_PRIME=1 LIBVA_DRIVER_NAME=i965 vainfo

and post output.

Re: Optimising OBS VA-API usage with AMD and Intel GPUs

One thing that may influence results is the xorg driver.

I think xf86-video-intel is not installed and the intel card uses xorg modesetting ?

If so, try installing xf86-video-intel.

One thing that may influence results is the xorg driver.

I think xf86-video-intel is not installed and the intel card uses xorg modesetting ?

If so, try installing xf86-video-intel.

You know plenty more than me (:

Installed, rebooted, no dice as far as I can tell.
Want whatever initialization output again?

Also:
Got this message while installing, worth a shot?

>>> This driver now uses DRI3 as the default Direct Rendering
    Infrastructure. You can try falling back to DRI2 if you run
    into trouble. To do so, save a file with the following 
    content as /etc/X11/xorg.conf.d/20-intel.conf :
      Section "Device"
        Identifier  "Intel Graphics"
        Driver      "intel"
        Option      "DRI" "2"             # DRI3 is now default 
        #Option      "AccelMethod"  "sna" # default
        #Option      "AccelMethod"  "uxa" # fallback
      EndSection

Thanks,

Re: Optimising OBS VA-API usage with AMD and Intel GPUs

hmm, haven't looked at xorg logs in a while, and if xf86-video-intel makes  a difference it should show there.

post xorg logs.

Re: Optimising OBS VA-API usage with AMD and Intel GPUs

Nothing weird in that log except the last 2 lines, and those appear to be after a considerable amount of time has passed.

DRI3 appears to be working fine, so I doubt switcihng to dri2 does anything.
Let's try to figure out if va-api for intel is working at all.

Change "Initial Display Output" to use the iGPU .
boot, start X and post

vainfo

output .
