Retrieving Information About a Movie

  • Article

[The feature associated with this page, MCI, 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 It has been superseded by MediaPlayer.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 MCI, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The following example sets the time format to frames and obtains the current position if the device is playing using the mciSendCommand function.

MCI_DGV_SET_PARMS mciSet; 
MCI_DGV_STATUS_PARMS mciStatus; 
 
// Put in frame mode. 
mciSet.dwTimeFormat = MCI_FORMAT_FRAMES; 
mciSendCommand(wDeviceID, MCI_SET, 
    MCI_SET_TIME_FORMAT, 
    (DWORD)(LPSTR)&mciSet); 
 
mciStatus.dwItem = MCI_STATUS_MODE; 
mciSendCommand(wDeviceID, MCI_STATUS, 
    MCI_STATUS_ITEM, 
    (DWORD)(LPSTR)&mciStatus); 
 
// If device is playing, get the position. 
if (mciStatus.dwReturn == MCI_MODE_PLAY)
{ 
    mciStatus.dwItem = MCI_STATUS_POSITION; 
    mciSendCommand(wDeviceID, MCI_STATUS, MCI_STATUS_ITEM, 
        (DWORD)(LPSTR)&mciStatus); 
 
    // Update the position from mciStatus.dwReturn. 
}
