FFMPEG drm hardware context creation failed: Cannot allocate memory

Hello. I got my Oculus Quest 2 a week ago, first time trying to use WiVRn. I have installed an apk client on my headset from the recent release and I have compiled the server. The problem is that I cannot connect to the server, I get this error:

I am unsure what it is related to, I seem to have all the codecs. I am on Gentoo, my videocard is Sapphire Pulse Radeon RX6700 (10GB). I tried to build with -DWIVRN_USE_NVENC=OFF, didn't change a thing.

Do you have ffmpeg with drm and vaapi support? On Gentoo you can use the ebuild in https://gitweb.gentoo.org/repo/proj/guru.git/tree/media-libs/wivrn which should have the correct dependencies.

I certainly seem to miss something, but cannot pinpoint it. I compiled the server without VAAPI and it works now. I'll try to build the ebuild from guru, thanks. I think I'll close the issue for now, as for now it seems the problem is entirely on my side.

Turned out I was somehow missing libdrm flag for ffmpeg package, though emerge actually seemed to think otherwise. Something is wrong with my system. Maybe that information will help someone else.
