NVIDIA RTX 30 Series Supports AV1 Accelerated Video Decoding

Well, this doesn't have a lot of consequence on Linux anyway except for stuff like mpv. Even the new firefox x11 vaapi support doesn't work on nvidia's proprietary drivers (even though there's a vdpau-to-vaapi library) since it requires DMA-BUF that nvidia can't use since it's exported GPL in this Linux kernel.

though I always hope to game on my GPU, I spend a lot more time watching h265 video, and Nvidia has been excellent at that with NVDEC. Is AMD just as good as Nvidia for 4k hardware decode of h264/h265?
AV1 is a great thing for futureproofing, as it will be used by Amazon, Netflix and Youtube

The boot ROM one can also replace with core boot et al. However, with a driver BLOB and no open register level specs you can't even fix bugs or run the card on other open systems, such as Haiku or other state of the art research.Last edited by rene; 02 September 2020, 03:12 AM.

This is misleading. Putting in hardware level acceleration for codecs in general does take up more die space but once you have hardware level acceleration for codecs, supporting additional codes is trivial when it comes to "die space". A lot of the die is reused between the different codecs for the fixed function algorithms that are used.

You would have a point if the graphics card in question didn't have codec acceleration at all in the first place, but this is not the case.
We are also not talking about AVX 512 hereLast edited by mdedetrich; 02 September 2020, 04:04 AM.

As long as a codec doesn't add new graphics transforms you can use the same hardware. So (e.g.) MPEG-2 is just a firmware program using hardware that supports h264. AV1 and VVC will actually share a lot of hardware - the pixel stuff has been out of patent for a while now.
