}


/*
This class takes a WebBrowser object as a parameter in its
constructor. It then attaches an event handler to the
DocumentCompleted event of the web browser, which will be called
when the web page finishes loading.

In the DocumentCompleted event handler, the class looks for
all video elements in the web page using the GetElementsByTagName
method of the HtmlDocument class. For each video element found,
it retrieves the value of the src attribute using the GetAttribute
method of the HtmlElement class, and prints it to the console.

To use this class, you can create an instance of it and pass
in a WebBrowser object that you have already navigated to the
web page containing the video stream. For example:
*/


WebBrowser webBrowser = new WebBrowser();
webBrowser.Navigate("https://example.com/video");
VideoStreamGetter videoStreamGetter = new VideoStreamGetter(webBrowser);

/*
Note that this class assumes that there is only one video element
in the web page. If there are multiple video elements, you will
need to modify the code to handle them appropriately.


Updated version of the C# class that retrieves the URL of a
video stream playing in a WebBrowser control, this time by
getting it from a metafile instead of directly from the video element:

using System.Windows.Forms;

namespace VideoStreamGetter
{
    public class VideoStreamGetter
    {
        private WebBrowser webBrowser;

        public VideoStreamGetter(WebBrowser webBrowser)

            this.webBrowser = webBrowser;
            this.webBrowser.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(DocumentCompleted);

        private void DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {

/*
This class works similarly to the previous version, but instead of
looking for video elements, it looks for meta elements with the name
attribute set to "twitter:player:stream". This is a common way of
specifying a video stream URL in a web page.

For each meta element found, the class retrieves the value of the
content attribute using the GetAttribute method of the HtmlElement
class, and prints it to the console.

To use this class, you can create an instance of it and pass in a
WebBrowser object that you have already navigated to the web page
containing the video stream. For example:
*/


WebBrowser webBrowser = new WebBrowser();
webBrowser.Navigate("https://example.com/video");
VideoStreamGetter videoStreamGetter = new VideoStreamGetter(webBrowser);

/*
Note that this class assumes that there is only one meta element with the
name attribute set to "twitter:player:stream". If there are multiple such
elements, you will need to modify the code to handle them appropriately.
