React (HTML) video tag won't autoplay on mobile devices

问题

I created a jsx variable to embeds a video into my html. Every other answer says to include muted, defaultMuted, and playsinline (which I already have). The videos autoplay in safari, chrome and firefox on my computer, but not on mobile. The start screen of the video loads, but it is paused. Do I need to do it slightly differently because I'm using React maybe?

I'm using an iPhone on iOS 13.3, the autoplay isn't working on safari, chrome and firefox, but only on mobile. The videos are all .mp4(.mov files also don't work).

var EmbedVideo = function(props) {
    return (
        <video webkit-playsinline playsinline autoplay="autoplay" className={props.className} muted defaultMuted loop>
            <source src={props.src} type="video/mp4" />
            Your browser does not support the video tag.
        </video>
    )
}

Update

So apparently 'muted' doesn't show up when I inspect the html of my website. The node looks like this. There's a few attributes that are missing actually.

<video autoplay="" class="video" loop="">
<source src="/videos/my_video.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>

I'm reading something about the muted attributed not working with React? Someone made a component that looks like it's the video tag, but functioning how it's supposed to(at least in my case with videos playing like gifs). I can't get it working though, it's not even autoplaying on Desktop. I'm trying just <VideoTag src={props.src} /> because I don't know what their poster variable is supposed to be.

回答1:

It looks like muted does not work properly when using React. I had to use something called dangerouslySetInnerHTML in order for muted to show up in the component.

var EmbedVideo = function(props) {
   return (
       <div dangerouslySetInnerHTML={{ __html: `
        <video
          loop
          muted
          autoplay
          playsinline
          src="${props.src}"
          class="${props.className}"
        />,
      ` }}></div>
   )
}

I think when you embed a video make sure to use the right path
