我正在尝试在我的C＃WinForms应用中显示来自IP cam的视频。我只需要显示视频，而不是相机菜单等。我正在考虑使用WebBrowser控件并以某种方式更改参数。如果您对此方法或任何其他方面有任何建议，请提供帮助。我不知道从哪里开始。 这是默认的IP cam页面：

答案 1 :(得分：0)
您的C＃应用程序中是否包含任何代码？
首先，我会看看你的代码的这一部分：
document.open();
document.write("<embed SCALE=\"ToFit\" width=\"" + resolutionW + "\" height=\"" + resolutionH + "\"" +
" type=\"video/quicktime\" qtsrc=\"rtsp://" + location.hostname + "/" + VideoPath + "\"" +
" qtsrcdontusebrowser src=\"quicktime.mov\" autoplay=\"true\" controller=\"true\"\>");
document.close();
在许多IF案例之后，您获得了位置路径和类型。也许你也希望它们在你的C＃代码中。然后设置WebBrowser控件的URI路径，看看会发生什么......
webBrowser1.Url = new Uri(myIPCamStringPath);
通常情况下，您可以使用标准浏览器直接连接每个IP-Cam。
