How to Perform Auto Repeat as Media Player Does

• Microsoft Windows Software Development Kit (SDK) for Windows version 3.1
• Microsoft Win32 SDK, versions 3.1, 3.5, 3.51, and 4.0
• Microsoft Video for Windows Development Kit (DK) version 1.1

The Media Player (MPLAYER.EXE) included with Microsoft Windows and Microsoft Windows NT (MPLAY32.EXE) provides an auto-repeat option that automatically repeats the playback of a multimedia file. You can incorporate this functionality into your application on Digital Video devices by using an extension to the standard Media Control Interface (MCI) commands as follows:

• When calling the mciSendString() function, add the word "repeat" to the play command, as in this example:

        mciSendString("play mov notify repeat", NULL, 0, hWnd);
  

• When calling the mciSendCommand() function, set the play flag MCI_DGV_PLAY_REPEAT. For example, to add auto repeat functionality to the MOVPLAY sample included with the Video for Windows DK, add the following line to the playMovie() function in MOVPLAY1.C, right before the mciSendCommand() function call:

        dwFlags |= MCI_DGV_PLAY_REPEAT;
