Hardware Video Decoding

Discussions center on hardware-accelerated video decoding in web browsers, especially H.264 and VP9 support, with frequent debates about its performance and enablement on Linux versus Windows/macOS, and across GPUs like Intel and NVIDIA.

H.264 is still hardware accelerated, isn't it?

I'm shocked there still isn't a hardware accelerator for video decoding.

probably because h264 en-/decoding is supported in hardware even on dated platforms

Does it do video hardware decoding in the browser? - I tried it and it didn't do it on nvidia.

Not when you have a hardware H264 chip.

I think this is only true on Linux. On my Windows and macOS installs, hardware video decoding works fine.

It is using hardware decoding in the browser. Try playing a YouTube video on an old computer with no hardware decode or an OS with it lacking like Haiku.

No hardware video decoding on Linux ...

You probably didn’t have Hardware Video Decoding enabled in the browser, that’s still not the default on Linux.

wouldn't that only be true if your hardware doesn't have the decoder isn't built into the hardware of your gpu?
