I tried this code to implement the autoplay video feature without the control bars but the issue that I faced was, the video was not autoplaying after refreshing the page. this project is in react. even after adding an autoplay attribute, the video is not autoplaying. what's the mistake am I doing?
I expect it to be autoplaying even after refreshing the page

<video id="coinSaverIcon" autoPlay playsInline>
<source src={coinsaverIcon} type="video/webm" />
</video>

You can add muted property
<video id="coinSaverIcon" autoPlay playsInline muted>
<source src={coinsaverIcon} type="video/webm" />
</video>

In some browsers autoplay (Chromium for example) is not allowed anymore.
Furthermore you shouldn't implement this kind of features for accessiblity issues.

html5 video: once the video is loaded, a flash is appeared. how to remove it?

I am using html5 and while the video is downloading I am using a fallback image in poster attribute. but the problem is once the video is downloaded a flashy screen is showing for a short period of time. how can I remove this, so that the flash will not visible?
<video class="bg-video" loop="" muted="" autoplay="" playsinline="" poster="https://i3.ytimg.com/vi/Zs0bsagDzw8/maxresdefault.jpg">
<source />
</video>
live site:
https://nordic.dnscheck.io/

If you mean the black frame, it's in your video so you should edit it out from there.
If you really can't edit that file anymore you can still kind of workaround that by using the media fragment syntax and make your video automatically seek to after that black frame:
<video muted loop autoplay
poster="https://nordic.dnscheck.io/bilder/poster.webp"
src="https://nordic.dnscheck.io/nordic.webm#t=0.8"
></video>
However beware that the black frame will still be here at the next loop.
Also, while it's not an issue for you since you do autoplay the video, one should note that (currently) setting the seeking time through the media fragment syntax will disable the poster once the video has loaded.

Video.js not working on iOS Safari, Chrome etc [duplicate]

I have some kind of a strange problem. I try to create a website with a looped background video. The code looks like this one:
<video src="video/bg.mp4" style="z-index: -1;object-fit: cover;" poster="video/bg.jpg" autobuffer autoplay loop muted></video>
This works perfectly fine on most browsers (IE struggles with this object-fit thing but I don't mind) but on iPhone the video won't autoplay but on iPad it does. I already read the New Policies for iOS and I think I meet the requirements (otherwise iPad won't autoplay). I did some other testing:
Removing overlaying divs won't fix it
Removing z-index won't fix it
Wifi or Cellular doesn't make a difference
Video filesize doesn't make a difference, too
Am I doing it wrong or does iPhone simply won't autoplay videos and always requires interaction? I only care for iOS 10, I know that the requirements were different on iOS 9

Does playsinline attribute help?
Here's what I have:
<video autoplay loop muted playsinline class="video-background ">
<source src="videos/intro-video3.mp4" type="video/mp4">
</video>
See the comment on playsinline here: https://webkit.org/blog/6784/new-video-policies-for-ios/

iOs 10+ allow video autoplay inline. but you have to turn off "Low power mode" on your iPhone.

Here is the little hack to overcome all the struggles you have for video autoplay in a website:
Check video is playing or not.
Trigger video play on event like body click or touch.
Note: Some browsers don't let videos to autoplay unless the user interacts with the device.
So scripts to check whether video is playing is:
Object.defineProperty(HTMLMediaElement.prototype, 'playing', {
get: function () {
return !!(this.currentTime > 0 && !this.paused && !this.ended && this.readyState > 2);
}});
And then you can simply autoplay the video by attaching event listeners to the body:
$('body').on('click touchstart', function () {
const videoElement = document.getElementById('home_video');
if (videoElement.playing) {
// video is already playing so do nothing
}
else {
// video is not playing
// so play video now
videoElement.play();
}
});
Note: autoplay attribute is very basic which needs to be added to the video tag already other than these scripts.
You can see the working example with code here at this link:
How to autoplay video when the device is in low power mode / data saving mode / safari browser issue

I had a similar problem and I tried multiple solution. I solved it implementing 2 considerations.
Using dangerouslySetInnerHtml to embed the <video> code. For example:
<div dangerouslySetInnerHTML={{ __html: `
<video class="video-js" playsinline autoplay loop muted>
<source src="../video_path.mp4" type="video/mp4"/>
</video>`}}
/>
Resizing the video weight. I noticed my iPhone does not autoplay videos over 3 megabytes. So I used an online compressor tool (https://www.mp4compress.com/) to go from 4mb to less than 500kb
Also, thanks to #boltcoder for his guide: Autoplay muted HTML5 video using React on mobile (Safari / iOS 10+)

I had the same problem - the video not play on iOS. I tried all the code options "playsinline autoplay loop muted". The problem was the video I received was in the wrong mp4 codec. So what helped us, was to upload the video to Vimeo and download the HD Version again. The video is now playing on all mobile devices.
You could also try to use mpeg streamclip. Here is a screenclip of VLC - those are the correct settings. Hope someone does not have to spend 2 hours searching for the problem - happy holidays

Here is a simple solution to auto-play the video in IOS, I've already tried and it is perfectly working on IOS, Android, also on all the browsers on various platforms.
simply use (data-wf-ignore) and (data-object-fit) Attributes for the video and data-wf-ignore for the source tag..
You can see the working example with code here at this Snippet:
<video id="myVideo" autoplay="" muted="" playsinline="" data-wf-ignore="true" data-object-fit="cover">
<source src="https://www.w3schools.com/html/mov_bbb.mp4" data-wf-ignore="true" />
</video>

Loading a specific video background depending on the browser

I have a video background, which works fine - I have specified 3 different formats so the video background works in different browsers, however it appears my page is loading all 3 of the video backgrounds at the same time. This is slowing down my page massively!
Just wondering is there a way (using Javascript or jQuery) to detect the browser and load only 1 video background based on what browser is being used?
<div class="header-unit">
<div id="video-container">
<video autoplay loop muted class="fillWidth" id="bgvideo">
<source src="backgroundvideo.mp4" type="video/mp4">
<source src="backgroundvideo.ogv" type="application/ogg">
<source src="backgroundvideo.webm" type="video/webm">
</video>
</div>
</div>

Displaying a video onLoad

What I would like is to have a video play in full screen once and then disappear leaving the web page behind. is this possible using Javascript, HTML and possibly CSS?
The video in question is called Website Opening.mp4

<video width="100%" autoplay="autoplay">
<source src="movie.mp4" type="video/mp4" />
</video>
Edit: When autoplay attribute is present, the video will automatically start playing as soon as it can i.e. when the page loads.
