To set the current stream, call IltmmMediaInfo::put_CurrentStream. Once the current stream has been set, information about that stream can be obtained by calling any of the following functions:

IltmmMediaInfo::get_StreamDuration

IltmmMediaInfo::get_StreamMediaType

IltmmMediaInfo::get_StreamSubtype

IltmmMediaInfo::get_StreamSubtypeName

IltmmMediaInfo::get_StreamType

IltmmMediaInfo::get_StreamTypeName
