Phoronix: AMD "EFC" Support Added To Mesa 22.1 For Radeon GPUs With VCN 2.0

For AMD Navi "RDNA1" GPUs and newer having at least Video Core Next 2.0 (VCN2) for the video coding block, a new feature was merged today into Mesa 22.1-devel for the open-source AMD video acceleration stack...

Amazing!

But come on, you better put 4:4:4 and improve the encoding quality on future encoding blocks or else...

Speaking of hardware video acceleration on Radeon, can AMD devs take a look at Firefox, because version 98 just broke video acceleration just for AMD hardware, and it doesn't looks like it will come back anytime soon.

Hardware-encoded 4:4:4 is pretty niche TBH.

In fact, what is the use case?

That has nothing to do with AMD, it's just Mozilla that needs to tweak their sandbox setup. (It's also broken on Intel)

What about RDNA2?

for one I would consider it necessary for VDI/remote desktop application. and as for game stresming many MMOs benefit from 4:4:4 too.

Even if niche, NVIDIA and Intel already support that.

In FF98, video hardware acceleration is working on my Intel iGPU, but not on AMD.

You're lucky. It doesn't change what he said though.
