Every IHV/OEM that needs metadata support must enable this through a custom INF file. UVC metadata support will be available only through the Media Foundation (MF) capture pipeline. UVC metadata support will be only available to frame based payloads. However, in the case of BULK endpoint, the metadata size will be limited to 240 bytes (due to the fact that all video frame data is transferred in a single video frame packet on BULK endpoints). The USB Video Class (UVC) frame metadata support will be available to ISOCH and BULK endpoints. Microsoft extensions to the USB Video Class specification enable new controls as well as the capability to carry well-defined frame-metadata in a standard format. ![]()
