=== NVIDIA === <!--T:23--> | |||
<!--T:24--> | |||
NVIDIA do not officially support accelerated video playback on Linux. A third-party implementation exists, but does not support Chrome<ref>https://github.com/elFarto/nvidia-vaapi-driver#chrome</ref>, and has significant limitations compared to the other implementations<ref>https://github.com/elFarto/nvidia-vaapi-driver#codec-support</ref>. | |||
<!--T:25--> | |||
NVIDIA users with a separate iGPU should generally prefer to use their iGPU for this, and therefore look to the above Intel and AMD sections instead. | |||
<!--T:26--> | |||
Users with only an NVIDIA GPU can attempt to use the third party implementation; the package is added to <code>hardware.graphics.extraPackages</code> by default, but it requires some additional setup to be useful<ref>https://github.com/elFarto/nvidia-vaapi-driver#configuration</ref>: | |||
