AV1 hardware decoder implementations
As we're on the verge of lots of devices with hardware AV1 decode, I think it's time for a sticky about this in particular.
As Chrome and Firefox explicitly block HEVC decode even if the OS supports it, PC browsers are where AV1 is going to have the biggest improvement delta. Most other platforms (including Edge and Safari) have HEVC today, where the quality @ perf of HEVC and AV1 are pretty equivalent given relative maturity of encoders. While SW encoders do work, performance is going to be a limitation for 4K and 10-bit (which HDR requires). And the lack of HW DRM provides lots of limitations on premium content availability. The Intel 11th gen Ice Lake CPUs are the first shipping PC implementation. Here's the best analysis of AV1 decode with Ice Lake I've seen: https://www.pcworld.com/article/3576...yzen-4000.html. I've not seen a test of DRM on Ice Lake, but I imagine it should work, and if it doesn't, a software bug fix is probably sufficient. tl;dr works great, and as expected. |

Tigerlake not Icelake, big difference. I have tested a few AV1 youtube videos in Chrome with my Tigerlake laptop and it works really good so far. ![]() Last edited by Yups; 28th November 2020 at 11:41. |

Bad news: it appears that Qualcomm isn't doing HW AV1 in its 2021 chipsets.

When I use D3D11 playback in DXVA Checker there are image artifacts on both LAV Decoder as well as Microsoft AV1 extension. DXVA2 runs on both but only with LAV Decoder it appears to use the GPU. Using MPC Home Cinema playback runs fine using D3D11 AV1 in LAV. |

Has anyone tried the Xbox Series X|S hybrid decoder yet? It's obviously complex to get working, but I can imagine the next gen game consoles are going to be a big share of the AV1 capable living room devices in 2021.

I am asking because I am not sure. But this sure sounded promising: https://forum.doom9.org/showthread.p...ox#post1929168
