In the DX11VideoRenderer sample, README.md, section Run the sample, states that the registration of DX11VideoRenderer.dll adds the Topology menu line "Add DX11 Video Renderer" of the topoedit application or enables this line to add the DX11VideoRenderer sink to the topology. First, the DX11 Video Renderer appears not as an individual menu line, but as an option in the Other transforms category of the Add transform dialog. But DX11VideoRenderer is not a transform, and the node cannot be added in this way. Even if it could be able to add, the topology would not resolve.

I added the necessary code to the topoedit to enable the promised functionality and published an updated topoedit to the https://github.com/vasilich-tregub/topoedit-with-DX11VideoRenderer repository.
