I want to check that 'M3U8' playlist exists or not.
If playlist is not exists then auto refresh the HTML play.
If playlist exists stop the auto refresh and play the playlist in HTML5 Video tag.

My code is as follows:

What I have tried:

<!DOCTYPE html>
<html lang="en">

        catch(err){

        </script>
        <div class="container" style="padding-top: 3%">
            <div class="row">
                <div class="col-6">
               <video id="video" class="video" autoplay(0) controls></video>
                       

                </div>
                <div class="col-3">
                    <div class="w3-panel w3-border"><h4>Camera Information</h4>
                        <p id="demo"></p>
                        
                    </div>
                </div>
            </div>
        </div>
    </body>
</html>

When I run this code on server it does not auto play the playlist.
