I went out and got the AMD 7800xt to do ultrafast AV1 encoding of large h264 and hevc files.
I am able to select VCN acceleration options in Windows but not Linux Handbrake.
I have tried the flatpak and both the Pop_OS and ppa deb packages of Handbrake. I have the latest mesa driver and am running the most current version of PopOS 22.04. I’ve had no issues gaming at all, just with picking the hardware encoder in Handbrake. Any ideas or rabbit holes I can go down?
Why can’t you decode and encode on the same device at the same time? I thought you could do a couple in parallel (but haven’t done so in a while)
Because one process will be running on the hardware, because of the way it works it can’t really share that hardware between processes. I’m not sure if that’s entirely a hardware limitation, but it seems to be enough of one that software hasn’t overcome it.
What if that process had multiple streams to decode/encode?
