问题描述

我有一个问题，我在 winform 中添加了冲击波播放器.但似乎youtube不再支持它了.那么如何将视频/youtube 视频嵌入到我的 winform 应用程序中?

解决方案

您可以使用

注意

您应该确保使用正确的网址.例如，对于您可以在以下地址看到的视频:https://www.youtube.com/watch?v=L6ZgzJKfERM，嵌入 url 为 https://www.youtube.com/embed/L6ZgzJKfERM.
此外，您还应确保允许以嵌入方式播放视频.有些视频只允许在 youtube 上播放，点击播放按钮后，您会收到此错误:
<块引用>
该视频包含来自 XXXXXX 的内容.它被限制从在某些网站或应用程序上播放.

I have a problem, i added shockwave player to the winform. But it seems that youtube does not support it anymore. So how can i embed a video/youtube video to my winform application?

解决方案

You can use a WebBrowser control to show embedded youtube video. To do so, put a WebBrowser control on a form and the put the following code in form:

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    var embed = "<html><head>"+
    "<meta http-equiv="X-UA-Compatible" content="IE=Edge"/>"+
    "</head><body>" +
    "<iframe width="300" src="{0}"" +
    "frameborder = "0" allow = "autoplay; encrypted-media" allowfullscreen></iframe>" +
    "</body></html>";
    var url = "https://www.youtube.com/embed/L6ZgzJKfERM";
    this.webBrowser1.DocumentText = string.Format(embed, url);
}

Note

You should make sure you use the correct url. For example for a video that you can see at this address: https://www.youtube.com/watch?v=L6ZgzJKfERM, the embed url is https://www.youtube.com/embed/L6ZgzJKfERM.
Also you should make sure the video is allowed to be played as embedded. Some videos are just allowed to play on youtube and after you click on play button you receive this error:

This video contains content from XXXXXX. It is restricted from playback on certain sites or applications.
