The current source media file is the file for which the IltmmMediaInfo interface/object gets information. To set the current source media file, call IltmmMediaInfo::put_SourceFile.
The number of streams obtained by this function can be used to iterate through all streams, acquiring information on each.
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
To get the current stream, call IltmmMediaInfo::get_CurrentStream.
