Firefox Merges Support for Vulkan Video Decoding to Boost Performance
I am excited to share that Firefox has officially merged support for Vulkan video decoding. This integration aims to significantly enhance video playback performance and efficiency across various devices by leveraging the powerful Vulkan API. Users can now expect smoother streaming and better hardware utilization, marking a major step forward in browser technology.

Cool, have been using vulkan video decoding via mpv for a while now and it seems fine with little or no performance hits. Glad it's made its way here as getting hardware decoding to actually work in ff has felt like a house of cards (more options are welcome). Does something need to be done to enable/switch to it?

I understand this is important mainly for Nvidia GPUs.
Is there any benefit at all for this (vs the existing VA-API) on Intel and AMD graphics?
VA-API seems to work very well on both of these platforms, as far as I've tested.

Interesting - will see if I can toy with it.
Word of caution though. I’ve found that on my machine (Linux/nvidia) unaccelerated video is way more power efficient. The second video is playing it kept the GPU in a high power state and that uses incrementally more power than the cpu doing software decoding
I had always assumed gpu would obviously be more efficient until I measured it

Does this mean that AV1 on Youtube will finally not melt my CPU, while my nvidia GPU is asleep, or is this just an enabler that will require more work to build upon?
