Occasionally, nvidia-vaapi-driver doesn't initialize in Firefox #395
Description
Sometimes, the driver simply doesn't initialize when I start playing a Youtube video in Firefox. The only output in logs I get is repetition of these lines:
libva info: VA-API version 1.20.0
libva info: User environment variable requested driver 'nvidia'
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so
libva info: Found init function __vaDriverInit_1_0
libva error: /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so init failed
libva info: va_openDriver() returns 1
After I restart Firefox and no further changes the driver starts working. I don't know what causes it to fail as I'm not doing anything specifically.
Firefox 143.0, but I also have noticed this with 142 series.
Nvidia driver 580.82.09, but I also noticed this with older 580 and 575 series.
Environment variables: NVD_BACKEND=direct LIBVA_DRIVER_NAME=nvidia MOZ_DISABLE_RDD_SANDBOX=1 NVD_LOG=1
