Does this AMF encoder support HEVC on Linux now?

FFmpeg can use the Nvidia VDPAU interface, but I cannot find any compiled version using that library.

There is no reasons for not using ffmpeg+vdpau in all the famous browsers.

Really? The one of the reasons was nvidia being buggy mess:

OpenMandirva in previous FFMpeg release patch it to support AV1 encoding and decoding. Decoding is made by dav1d and encoding via librav1e.

Compiling FFmpeg is quite easy. I've even compiled it on an Arm SBC with only 512MB this is how easy it can be.

The best decoder for Nvidia is the newer nvdec-based decoder by the way. All you then need to do is to compile it and MPV for instance will pick it up as it uses the shared libraries of FFmpeg:

Is there a way to use AMF with Mesa and not the pro drivers?

I think AMD has a compatibility tool in the SDK.

And then the GPU will constantly run in power wasting P2 CUDA state for even any 240p video, how wonderful.

Maybe yours does this and because you're a drama queen. Mine however doesn't and stays at the lowest frequency.
