[The feature associated with this page, MCIWnd Window Class, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of MCIWnd Window Class, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Some devices support playback in the reverse direction. You can play the content of such a device in the reverse direction by using the MCIWndPlayReverse macro. This macro defines the playback scope from the current playback position to the beginning of the content. The digital-video device, MCIAVI.DRV, can play backward. Devices that cannot play backward, such as CD audio, can issue an error message when MCIWndPlayReverse is invoked.
