Details

Discovered while working on bug 1540581.

We go through D3D11ShareHandleImnage::GetAsSourceSurface() which will always convert the image (typically NV12/P010/P016) into a B8G8R8A8 texture.

I'm told by :jgilbert that this shouldn't happen and the fastpath (Which uses the image natively) should be used.

This sounds like it's quite a big problem and could be a big win to fix it? Is this Image type the common case on windows?

Priority: -- → P3
