gstreamer-d3d11-overlay

Using GStreamer with Direct3D11/Direct3D9 interop layer in .Net

There is no direct support in WPF to display UI elements over a D3D component due to the airspace issue. This project will tackle this issue by implementing a Direct3D11/Direct3D9 interop layer and by using the D3DImageEx class.

The D3DImageEx class will create a D3D11Texture which is created with the D3D11_RESOURCE_MISC_SHARED. This texture will be used for the SetBackBuffer method and later used for the d3d11videosink element in the gstreamer code. Sample project
