Remarks
The MediaCapture object may store the image data of a VideoMediaFrame acquired from a MediaFrameSource in either CPU or GPU memory. When MemoryPreference is set to Cpu, CPU memory is used and therefore the SoftwareBitmap property of acquired VideoMediaFrame objects will be non-null and contain the image data for the frame. When Auto is specified, the system will dynamically choose the optimal memory location for the current device. If the system chooses to use GPU memory, the Direct3DSurface property of acquired VideoMediaFrame objects will be non-null and contain the image data for the frame.
