You can easily force enable it. But the stability varies wildly with hardware. My iGPU works good, my NVIDIA 920m works good but the old AMD 5750HD causes crash

Go to about:config and set: layers.acceleration.force-enabled to true.

- kuschku 10y agoNope, that's hardware accelerated layers and compositing. Video is always decoded on CPU on Linux. Always. Eating, at 4K, around 5-10% on an i7-6700. On a smaller laptop, this can eat an entire core, and make the browser close to unusable.
- hashhar 10y agoReminds me of https://stackoverflow.com/questions/23289157/how-to-use-hardware-acceleration-with-ffmpeg https://stackoverflow.com/questions/23289157/how-to-use-hard.... The entire Linux graphics stack is fragmented and makes things worse for both users and developers.
- kuschku 10y agoThe entire Linux world is fragmented. Luckily, things are getting better with systemd, wayland, etc, aiming to provide a simple and standardized way to interface with some parts of the system for developers.
- TekMol 10y agoOn my laptop, Firefox cannot play any youtube video at the default resolution. Have to manually set it to 360p.
- throwaway2048 10y agoits not just that video is CPU decoded, MPV preforms massively better on slower systems, even with software only decoding. Its just plain slower code for whatever reason

- TD-Linux 10y agoBoth Firefox and mpv use the same decoder for Youtube (ffvp9). With accelerated layers forced on and fullscreen, you should see roughly comparable performance. For windowed, it's currently expected to be somewhat more taxing than mpv because all of the extra window contents are composited every frame.
