[Winform]Media Player组件全屏播放的设置

摘要

在设置程序开始运行时，让视频全屏播放时，直接设置

windowsMediaPlay.fullScreen = true;

会报错，代码如下

                windowsMediaPlay.URL = _videoPath;
                windowsMediaPlay.Ctlcontrols.play();
                windowsMediaPlay.fullScreen = true;
                windowsMediaPlay.ClickEvent += windowsMediaPlay_ClickEvent;
                windowsMediaPlay.KeyUpEvent += windowsMediaPlay_KeyUpEvent;
                windowsMediaPlay.StatusChange += windowsMediaPlay_StatusChange;

错误

抱着相信微软的心情，就在猜想，可能是位置不对，是不是必须视频在播放中才可以设置全屏？

所以在视频状态变化的事件中，这样设置

        void windowsMediaPlay_StatusChange(object sender, EventArgs e)
        {
            /*  
             * 0 Undefined Windows Media Player is in an undefined state.(未定义) 
               1 Stopped Playback of the current media item is stopped.(停止)

           */
            //判断视频是否已停止播放  
            if ((int)windowsMediaPlay.playState == 1)
            {
                //停顿2秒钟再重新播放  
                System.Threading.Thread.Sleep(1000);
                //重新播放  
                windowsMediaPlay.Ctlcontrols.play();
            }
            else if ((int)windowsMediaPlay.playState == 3)
            {
                windowsMediaPlay.fullScreen = true;
            }
        }

Remarks

For full-screen mode to work properly when embedding the Windows Media Player control, the video display area must have a height and width of at least one pixel. If uiMode is set to "mini" or "full", the height of the control itself must be 65 or greater to accommodate the video display area in addition to the user interface.

If uiMode is set to "invisible", then setting this property to true raises an error and does not affect the behavior of the control.

During full-screen playback, Windows Media Player hides the mouse cursor when enableContextMenu equals false and uiMode equals "none".

If uiMode is set to "full" or "mini", Windows Media Player displays transport controls in full-screen mode when the mouse cursor moves. After a brief interval of no mouse movement, the transport controls are hidden. If uiMode is set to "none", no controls are displayed in full-screen mode.

Note  Displaying transport controls in full-screen mode requires the Windows XP operating system.

 

If transport controls are not displayed in full-screen mode, then Windows Media Player automatically exits full-screen mode when playback stops.
