Seungha Yang	88efaa35a8	d3d12download: Do not overwrite fence of non-writable memory ... A fence configured in GstD3D12Memory should be used only for write access to be completed. And because d3d12 -> d3d11 copy path is read access to d3d12 resource, we should not set fence to memory. Otherwise another read access to the d3d12 resource will wait for d3d11 device context's copy operation although simultaneous read access is allowed. Use background thread to keep d3d12 resource and wait for d3d11 device's copy operation instead.

Seungha Yang	e692bf0fb9	d3d12memorycopy: Enhance d3d12 to d3d11 copy ... If a d3d12 memory holds non-direct-queue fence but the fence was created with D3D12_FENCE_FLAG_SHARED flag, use the fence instead of waiting for fence at CPU side. Note that d3d12ipcsrc or d3d12screencapture elements will hold such sharable fence. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/7139>	2024-07-08 09:57:04 +00:00
Seungha Yang	c0a02affa4	d3d12: Add support for resource copy between d3d11 and d3d12 ... If driver can support cross-api resource sharing, use device-to-device resource copy in d3d12upload/download elements.
