How to stop a YouTube video?

Hello!

I am using CefSharp.WinForms.ChromiumWebBrowser in my win forms app. It's in a very simple form, which is activated from a 'help' menu item.

I've managed to get the video to load and play back perfectly.

When the form is then hidden from view, I want the video playback to stop. I don't want to destroy the form, because the user might want to resume watching from where they left off!

Is there any way to programmatically stop the video? I've spend all day trying to find the answer!

Many thanks!

Here's my code (very simple!)

using System;
using System.Windows.Forms;

namespace MyNameSpace
{
    public partial class YTForm : MyInterface.BaseForm
    {
        public YTForm()
        {
            InitializeComponent();
            ShowOK = false;
            this.FormClosing += YTForm_FormClosing;
            this.Activated += YTForm_Activated;
            this.VisibleChanged += YTForm_VisibleChanged;
        }

        private void YTForm_VisibleChanged(object sender, EventArgs e)
        {
        }

        private void YTForm_Activated(object sender, EventArgs e)
        {
        }

        private void YTForm_FormClosing(object sender, FormClosingEventArgs e)
        {
            // stop playback if running.. ???

        }

        string videoCode;
        public string VideoCode
        {
            get => videoCode;
            set
            {
                if (videoCode != value)
                {

                    videoCode = value;

                    string html = "https://www.youtube.com/embed/{0}";

                    string vc = videoCode.Split('=')[1];
                    var str = string.Format(html, vc);
                    chromiumWebBrowser1.LoadUrl(str);
                }
                return;
            }
        }
   }
}

In use:

private void workflowTODOToolStripMenuItem_Click(object sender, EventArgs e)
        {
            yTForm.VideoCode = @"https://www.youtube.com/watch?v=0Y_n_iuVF-U";
            yTForm.Show(this);
        }

You can interact with the browser via Javascript or Key/Mouse emulation.

I believe YouTube will pause/resume a video when the space key is pressed, so that's one option to try. Or you can look into javascript options for pausing media.
