Remarks
The label for each stream in a single MediaEncodingProfile must be unique. Calling SetVideoTracks to add a stream descriptor containing a duplicate label will result in an invalid argument error.
If you use a MediaFrameSourceGroup to capture multiple video streams at once, the system will attempt to match the Label property of each VideoStreamDescriptor with the Id property of each MediaFrameSourceInfo in the group in order to match the capture device with the approproate stream descriptor.
