你好bp_l，

从下面的帖子看，它似乎是WPF中的问题，作为一种解决方法，我建议您可以将视频下载到本地路径然后打开它，以下代码供您参考。

 public Window1（）
 {
 InitializeComponent（）; 
 
 MediaPlayer player = new MediaPlayer（）; 
 var source = new Uri（@" https://www.musictime-studio.com/webfile/musical_demo/20180730045604.mp3" ;,UriKind.Absolute）; 
 
 byte [] video = GetByteFromUrl（@" https://www.musictime-studio.com/webfile/musical_demo/20180730045604.mp3"）; 
 System.IO.File.WriteAllBytes（" temp1.mp3"，video）; 
 player.Open（new Uri（" temp1.mp3"，UriKind.Relative））; 
 VideoDrawing drawing = new VideoDrawing（）; 
 drawing.Rect = new Rect（0,0,300,200）; 
 drawing.Player = player; 
 player.Play（）; 
 DrawingBrush brush = new DrawingBrush（drawing）; 
 this.Background = brush; 
} 
 
 
 private byte [] GetByteFromUrl（string url）
 {
 byte [] videoData = null; 
 
使用（var wc = new System.Net.WebClient（））
 videoData = wc.DownloadData（url）; 
返回videoData; 
}

Hi bp_l,

From the following thread, it seems that it is know issue in WPF, As a workaround, I would suggest that you could download the video to the local path then open it, the following code for your reference.

public Window1()
        {
            InitializeComponent();

            MediaPlayer player = new MediaPlayer();
            var source = new Uri(@"https://www.musictime-studio.com/webfile/musical_demo/20180730045604.mp3", UriKind.Absolute);

            byte[] video = GetByteFromUrl(@"https://www.musictime-studio.com/webfile/musical_demo/20180730045604.mp3");
            System.IO.File.WriteAllBytes("temp1.mp3", video);
            player.Open(new Uri("temp1.mp3", UriKind.Relative));
            VideoDrawing drawing = new VideoDrawing();
            drawing.Rect = new Rect(0, 0, 300, 200);
            drawing.Player = player;
            player.Play();
            DrawingBrush brush = new DrawingBrush(drawing);
            this.Background = brush;
        }


        private byte[] GetByteFromUrl(string url)
        {
            byte[] videoData = null;

            using (var wc = new System.Net.WebClient())
                videoData = wc.DownloadData(url);
            return videoData;
        }
