object

      Object associated with this media control interface command. The object can be one of the following:

      • Device type
      • Device name
      • Filename
      • Alias
      DESTINATION
        Requests the position and size of playback video relative to playback window.
      MONITOR DESTINATION
        Requests the position and size of monitor video relative to monitor window.
      RECORD DESTINATION
        Requests the size of movie to be recorded. The coordinates returned are those previously set with the PUT object RECORD DESTINATION AT rect command.

        ADJUSTED

          Returns the coordinates that will actually be used to record a movie or get an image buffer based on what was previously set with the PUT command and the capabilities of the capture hardware.

          An application can use the WHERE command with and without the ADJUSTED keyword to see the effect of the multiple-integral rule imposed by capture cards that cannot distort. See PUT for more information on the multiple-integral rule.

        RECORD SOURCE
          Requests the position and size of source video relative to video source extent. The coordinates returned are those previously set with the PUT object RECORD SOURCE AT rect command.

          ADJUSTED

            Returns the coordinates of the source rectangle based on what was previously set with the PUT command and the capabilities of the capture hardware.

            An application can use the WHERE command with and without the ADJUSTED keyword to see the effect of the multiple-integral rule imposed by capture cards that cannot distort. See PUT for more information on the multiple-integral rule.

          WINDOW
            Requests the position and size of playback window relative to its parent.

            MONITOR

              Requests the window size and position for the monitor window.
            WAIT
              The command is executed synchronously. The function waits until the requested action is complete before returning to the application.
            NOTIFY
              The command is executed asynchronously, allowing control to be returned immediately to the application. When the requested action is complete, an MM_MCINOTIFY message is sent to the application window procedure.
