Firefox VA-API with Geforce GTX1050

Hi,

I would like to enable hardware acceleration in Firefox, using libva-nvidia-driver.
Before installation and configuration it is good to know if VA-API comes from that driver and native Nividia diriver would not collide with each other?
Means I have H.265/HEVC 8bit movie which is supported by native nvidia and not by libva-nvidia-driver.  To decode it which driver would be used in such situation?
And what about encoding? Will these drivers be used interchangeably or only VA-API ?

Re: Firefox VA-API with Geforce GTX1050

The native nvidia driver only directly supports VDPAU/NVDEC, you emulate VAAPI over NVDEC with that package there is no possible conflict between the two, and yes you can use them interchangeably, which will be used where and how is up to you setting the relevant parameters properly for whatever tool you're using. If you configure ffmpeg to use NVENC/DEC directly then there's no overlap or conflict with VAAPI for example. Same for whatever video player you are referring to for the movie,  it "might" pick the wrong default because you have a working VAAPI implementation but I'm not aware of any that wouldn't let you explicitly choose which decoding API should be used.

Thank you for the answer. I configured VA-API and as you said it works without any conflict with actual driver.
