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.
