Augmented Reality for UE4

Hi and!

I wonder if this plugin could support the video capture card? Or is there any other solution for my project that the video stream from a remote quadcopter have to be transmitted to unreal engine as texture? Now I use a video capture card to receive the video and get the image using a C++ API. But I have no idea how can I transfer the pixel buffer variable into the texture that could be used in unreal engine.
Anyone know the answer?
