WM/MCDI

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The WM/MCDI attribute contains the music CD identifier. This is a binary dump of the table of contents from the CD that is used to uniquely identify the CD.

Remarks

This attribute is compatible with the ID3 frame, MCDI. The ID3 specification for the MCDI frame requires that only one such frame exist per file and that a valid TRCK frame exist. The metadata editor does not perform any validation for these rules. Also, the size of WM/MCDI is not limited to 804 bytes, as is the MCDI ID3 frame.
