Our Direct3D11 abstraction layer has been improved and it gained good shape from API point of view. Also, On Windows, GstD3D11 has various advantages over GstGL in terms of compatibility/stability/feature/performance. Note that WGL implementation is known to be buggy for some drivers/vendors/scenario (that's a reason why Google implemented ANGLE). Moreover, GstGL is not fully optimized for Windows unfortunately. It's the time to open this interface to application developers for various optimized processing using our Direct3D11 infrastructure.
