WM/Track
The WM/Track attribute contains the track number of the content. This attribute is zero-based and is supported for backward compatibility. New content should use the WM/TrackNumber attribute instead.
Global Constant
g_wszWMTrack
Data Type
WMT_TYPE_STRING
Remarks
Many existing applications write the value for WM/Track as a DWORD. If you create an application that plays files from unknown sources, you should include code to handle both string and DWORD values.
