GetVideoPortInputFormats (Windows CE 5.0)
This callback function fills the specified array with all of the formats that the video port can accept and puts that number in the dwNumFormats member of the DDHAL_GETVPORTINPUTFORMATDATA structure. If lpddpfFormat is NULL, it only fills dwNumFormats with the number of formats that it can support. This function is needed because the supported formats might vary depending on the electrical connection of the video port. This callback function is required.
