How does hardware video acceleration work on ARM? I would like to install Fedora on a Raspberry Pi, but first I would like to make sure I can take advantage of hardware video acceleration. Most likely ARM GPUs don’t support VAAPI and I don’t think there are tools equivalent to vainfo and intel_gpu_top. I’m looking for someone who can provide me with information on this topic 🙂 Thanks
It’s not an environment variable, it’s the kernel detecting and loading the proper modules that hand off acceleration to userspace driver packages like Mesa.
