Remarks

This object is the parallel to VideoStreamDescriptor and AudioStreamDescriptor, but is used for streams that contain arbitrary data. An example usage of this type of stream would be to encode a stream of GPS coordinates that are captured simulataneously with a video stream.

When creating a MediaEncodingProfile, call SetVideoTracks, passing in one or more VideoStreamDescriptor objects to provide information about the video tracks to be encoded.

Constructors
