 |
|
Whenever I run vainfo, this happens:
| Code: |
$ vainfo
Trying display: drm
libva info: VA-API version 1.21.0
libva info: Trying to open /usr/lib/va/drivers/nouveau_drv_video.so
libva info: Found init function __vaDriverInit_1_21
nvc0_screen_create:1002 - Base screen init failed: -19
libva error: /usr/lib/va/drivers/nouveau_drv_video.so init failed
libva info: va_openDriver() returns 2
vaInitialize failed with error code 2 (resource allocation failed),exit
|
Even if I set LIBVA_DRIVER_NAME to nouveau it still doesn't work.
Any help is appreciated. |

Never tried VAAPI with nouveau, but afaik nouveau only support hardware acceleration for decoding with specific old cards (and most also need an external firmware extracted from nvidia-drivers, see https://nouveau.freedesktop.org/FeatureMatrix.html), and then that's for vdpau.. no idea how that works out with mesa+vaapi, so I wouldn't be surprised that it fails. I personally wouldn't bother trying and just do USE=-vaapi
On that note, nvidia-drivers doesn't officially support vaapi too (only vdpau or nvenc/nvdec). There is nvidia-vaapi-driver but it's bit of a hack to use nvdec through it and (currently) only works for some specific usage (like firefox, not chromium) and with recent enough drivers so it won't work for legacy cards. |

I have used the nvidia-vaapi-driver for well over a year now.
https://github.com/elFarto/nvidia-vaapi-driver
It is quick to build from source. It works on Firefox mainly when just playing Youtube videos.
To be honest, I can't really tell any difference but I have a powerful CPU, plenty of RAM, and near TOTL GPU.
I can verify that it is working in Nvidia Settings and nvidia-smi but there is not any noticeable difference with or without the driver installed.
If you have a lower end system, laptop, iGPU or such setup, there may be improved performance on Firefox.
In that case, it make be worth checking out. |

Maybe it is to do with another issue I have been having.
See below
| Code: |
$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x45 cap: 0x2, Sink Output crtcs: 4 outputs: 3 associated providers: 0 name:modesetting

| If worst-comes-to-worst, I'll just reinstall Gentoo. |

| You are welcome to spend your time doing that, but reinstalling Gentoo rarely fixes problems you do not understand. Worse, if you do not understand how the problem happened, you have no way to avoid making it happen again at some indeterminate point in the future. |

Could it be that CONFIG_DRM_NOUVEAU is enabled and not a module or could it be something else in my kernel config?
Also my system is quite unusual and that could contibute to the problem. For example, I use mdevd instead of udev and I use musl instead of glibc. |
