24H2还是测试版吧,Chromium的SDK目前还没法引用24H2的GUID。
另外,Chrome现在依赖Video Processor去把Y416,Y410,Y216,Y210转到RGB10A2,如果不支持VP光能解码没用(Intel他们家都支持,NVIDIA就不好说了。。。),你可以点一下第二个面板“Processor Device”,切到“D3D11”:
看看D3D11选项面板支持的哪些格式的VP,截个图发过来。
看图里这样子,是不支持我说的那几种像素格式转换的,Chromium想支持会非常麻烦。
I just installed Windows11 24H2 26100.1150 today, and confirmed that when using RTX3050 I could see the HEVC main12 GUID, but the question is, HEVC main12 is a 12bit 4:2:0 format, and it seems this GUID can only output P010 instead of P016, so NVIDIA sucks again.
I also don't see the expected main10 4:4:4 and main12 4:4:4 GUID, so its useless to only support main12 4:2:0. Most people would use HEVC rext only if they need 4:2:2/4:4:4 support, it make no sense to support the new GUID for now.
I can see these new GUID appears on my Intel A380 though:
But again, the question is: if nvidia doesn't support those new 4:2:2/4:4:4 guid, then the existing guid for intel should be enough.
Let just wait if NVIDIA could add 4:2:2/4:4:4 GUID with proper VideoProcessor support, at least for now we can do nothing.
Will not support 12bit 4:2:0 unless NVIDIA support 12bit 4:4:4.
