C# AxWindowsMediaPlayer循环

Question

我有这个恼人的问题，我不能追踪它出了什么问题。我正在用代码创建一个Windows Media Player，并且我正在尝试循环一个视频...它会循环，但只有一次...

所以它播放视频，然后再一次。然后它就会停下来，显示视频的结尾。所以它看起来好像只循环一次。

这是我的代码：

        try {
            wmPlayer = new AxWMPLib.AxWindowsMediaPlayer();

            wmPlayer.enableContextMenu = false;
            ((System.ComponentModel.ISupportInitialize)(wmPlayer)).BeginInit();
            wmPlayer.Name = "wmPlayer";
            wmPlayer.Enabled = true;
            wmPlayer.Dock = System.Windows.Forms.DockStyle.Fill;
            mainForm.Controls.Add(wmPlayer);
            ((System.ComponentModel.ISupportInitialize)(wmPlayer)).EndInit();
            wmPlayer.uiMode = "none";

            if(kind == "idle") {
                IdleVideo(name);
            }
        }
        catch { }
    }

    private static void IdleVideo(string name) {
        System.Diagnostics.Debug.WriteLine("Video called once");
        wmPlayer.URL = @"C:\ProjectSilver\assets\RadarDetectie\idle\" + name + "_idlescreen_movie.ogv";
        Debug.WriteLine(wmPlayer.URL);
        wmPlayer.settings.setMode("loop", true);

        wmPlayer.Ctlcontrols.play();
    }

所以我希望你们能帮上忙，为什么它不继续播放？

为PlayStateChange事件添加事件处理程序：

wmPlayer.PlayStateChange += wmPlayer_PlayStateChange;

然后在事件处理程序中检查e.newState==8是否表示media ended

AxWMPLib.AxWindowsMediaPlayer wmPlayer;
private void player_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
{
   if(e.newState==8) // MediaEnded
        // call function to play the video again     
}

对于播放状态，检查以下内容：http://msdn.microsoft.com/en-us/library/windows/desktop/dd562460%28v=vs.85%29.aspx

编辑：我不知道你用kind做了什么，也不知道你的代码的第一部分是在哪里定义的，但这对我来说很有效：

AxWMPLib.AxWindowsMediaPlayer wmPlayer;

private void button2_Click(object sender, EventArgs e)
    {
        wmPlayer = new AxWMPLib.AxWindowsMediaPlayer();
        wmPlayer.CreateControl();
        wmPlayer.enableContextMenu = false;
        ((System.ComponentModel.ISupportInitialize)(wmPlayer)).BeginInit();
        wmPlayer.Name = "wmPlayer";
        wmPlayer.Enabled = true;
        wmPlayer.Dock = System.Windows.Forms.DockStyle.Fill;
        this.Controls.Add(wmPlayer);
        ((System.ComponentModel.ISupportInitialize)(wmPlayer)).EndInit();
        wmPlayer.uiMode = "none";
        wmPlayer.URL = @"C:\...";
        wmPlayer.settings.setMode("loop", true);

        wmPlayer.Ctlcontrols.play();
    }

只需使用

    private void Form1_Load(object sender, EventArgs e)
    {
        // give the path of your video here
        axWindowsMediaPlayer1.URL = "Path of your video";
        // this line will automatically start your video
        axWindowsMediaPlayer1.settings.autoStart = true;
        //here the system will automatially create a thread and will keep on 
         running your video...
        axWindowsMediaPlayer1.settings.setMode("loop", true);
    }
