From e7bf5576e599593b1bba5bbf2a7cd6d4270c7809 Mon Sep 17 00:00:00 2001 From: James Ross-Gowan Date: Wed, 1 Nov 2017 22:38:41 +1100 Subject: vo_gpu: hwdec_d3d11va: allow zero-copy video decoding Like the manual says, this is technically undefined behaviour. See: https://msdn.microsoft.com/en-us/library/windows/desktop/ff476085.aspx In particular, MSDN says texture arrays created with the BIND_DECODER flag cannot be used with CreateShaderResourceView, which means they can't be sampled through SRVs like normal Direct3D textures. However, some programs (Google Chrome included) do this anyway for performance and power-usage reasons, and it appears to work with most drivers. Older AMD drivers had a "bug" with zero-copy decoding, but this appears to have been fixed.
