How to make a video slide and images with asp.net?

Question

I need to make a slide video and images with asp.net, SlideExtender only works with pictures, the only option left is to make conditional updatepanel with a timer but I ran out of ideas, please some other ideas:

 

HTML Code:

 

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
        <div>
            <asp:Timer ID="SlideShowTimer" runat="server" Interval="5000" OnTick="SlideShowTimer_Tick"></asp:Timer>
            <asp:UpdatePanel ID="SlideShowUpdPnl" runat="server" UpdateMode="Always">
                <ContentTemplate>
                    <div id="DivSlide">
                        <img id="SlideShowImage1" src="images/logo11.png" runat="server" alt="Sanmina-SCI" visible="true" />
                          <video runat="server" id="SlideShoVideo" src="Uploads/Avideo1.mp4" controls="controls" autoplay="autoplay" visible="true"/>
                        <asp:Label ID="LblTitleSlideShow" runat="server" Text=""></asp:Label>
                    </div>
                </ContentTemplate>
                <Triggers>
                    <asp:AsyncPostBackTrigger ControlID="SlideShowTimer" EventName="Tick" />
                </Triggers>
            </asp:UpdatePanel>
        </div>

Code Behind: 

protected void SlideShowTimer_Tick(object sender, EventArgs e)
        {
            DateTime later = DateTime.Now.AddSeconds(.5);
            while (DateTime.Now < later)
            {
                LblTitleSlideShow.Text = "Time Later : " + later;
            }
            this.SlideShowImage1.Src = RandomImageName();
            this.LblTitleSlideShow.Text += this.SlideShowImage1.Src.ToString();

        }


 private string RandomImageName()
        {
            Random rand = new Random();
            int RandomInt = rand.Next(0, 5);
            string url = null;
            switch (RandomInt)
            {
                case 0:
                    url = "../Uploads/Jellyfish.jpg";
                    break;
                case 1:
                    url = "../Uploads/Lighthouse.jpg";
                    break;
                case 2:
                    url = "../Uploads/sanmina-logo.png";
                    break;
                case 3:
                    url = "../Uploads/Tulips.jpg";
                    break;
                case 4:
                    url = "../Uploads/Koala.jpg";
                    break;
                case 5:
                    url = "../Uploads/Penguins.jpg";
                    break;
                default:
                    url = "../Uploads/123.png";
                    break;
            }
            return url;
        }
