For Ubuntu machine with NVIDIA graphics card, here’s how to implement hardware acceleration for video playback in Firefox web browser.

Firefox so far only supports VA-API for GPU decoding to offload CPU and save power. Both Intel and AMD GPUs support VA-API. However, NVIDIA so far supports the api only through the open-source Nouveau driver.

If you have only NVIDIA GPU running with proprietary driver, then hardware video acceleration does not work out-of-the-box for Firefox.

For choice, there are libvdpau-va-gl1 driver (h.264 only) or libva-vdpau-driver, but both seems no longer updated. The best choice so far is the free open-source nvidia vaapi driver.
