HTML5 video not loading in chrome, but works when the developer console is opened up

问题

I am working on a web app for a client, and there is a problem with the HTML5 video tag.

The problem is that the video won't load in chrome, but works on Safari, Firefox and IE.

So I start debugging in chrome, but I found out that if I refresh the page with console opened, the video would load. But when I close the console and refresh, the video would not load...

Here are the few things I have tried:

Have multiple type of videos, in mp4 and webm. in componentDidMount, replace the video with the same code.

But none seems to work...

<div class="Top">
    <div class="video-container BGVideo">
        <video id="videobg" class="video-background" preload="true" loop="" autoplay="" poster="/img/azzura.jpg">
            <source src="/img/azzura.mp4">
            <source src="/img/azzura.webm">
        </video>
        <div class="video-overlay"></div>
        <div class="video-content">
            <div class="BGContent">
                <div class="scrollDown">
                    <a class="button"><i class="fa fa-chevron-down"></i></a>
                </div>
            </div>
        </div>
   </div>
</div>

I figured out my problem was that I have autoplay enabled, but with chrome's new policy, autoplay isn't allowed unless it's the video is muted, so adding the muted attribute fix the problem.

This worked fine for me.

Completed parameters loop="false" and autoplay="false" as you had them emptied e.g. loop="", etc.

<div class="Top">
    <div class="video-container BGVideo">
        <video id="videobg" class="video-background" preload="true" loop="false" autoplay="false" poster="">
            <source src="https://www.sample-videos.com/video/mp4/720/big_buck_bunny_720p_1mb.mp4">
        </video>
        <div class="video-overlay"></div>
        <div class="video-content">
            <div class="BGContent">
                <div class="scrollDown">
                    <a class="button"><i class="fa fa-chevron-down"></i></a></div>
                </div>
            </div>
        </div>
    </div>
