HTML5 video autoplay doesn't work on phones and tablets

HTML5 video autoplay doesn't work on phones and tablets.
I checked on the phone with Android 4.2.2 in Chrome 60 and iPad. Also, I checked on the phones with Android 4.2.2 and 7.0.
I tried to use such scripts:
// 1
$(window).load(function () {
$("video[autoplay]").get(0).play();
});
// 2
$(window).on("scroll", function() {
var video = $("video[autoplay]").get(0);
if (video.paused) {
video.play();
}
});
// 3
$(window).on("touchstart touchmove touchend touchcancel", function () {
var video = $("video[autoplay]").get(0);
if (video.paused) {
video.play();
}
});
HTML:
<video id="video" autoplay="" loop="" playsinline="" muted="">
<source src="videos/video1.mp4" type="video/mp4">
</video>
The first variant doesn't work at all.
The second one runs scripts inside of it, but the video doesn't play.
The third one runs scripts inside of it, but the video play only on the click!

Autoplay will not work with mobile browsers because mobile will be on network data, and if any auto play video starts playing, then it will consume data without user's permission and knowledge. So this is disabled for mobile browsers by default.
But still you can check these url for your solution:
Since the release of iOS 10 Apple has allowed video autoplay: https://webkit.org/blog/6784/new-video-policies-for-ios/
Chrome 53 on Android also allowing video autoplay: https://developers.google.com/web/updates/2016/07/autoplay

Javascript autoplay video (mp4) on Opera browser?

I have made a website which we use on a TV to welcome guests/customers to our business. There's a SQL database which we write their names to be presented on the screen, and there is also a video which is playing in a different frame on the same website.
This all works very well on desktop PC Chrome. But we use the built in browser in the TV (which is a business model used for stuff like this). The browser is Opera and it supports HTML5.
Problem is that after a while, can be 2 hours, can be a day, it will stop playing the video, and just show a black frame.
This is the code:
<source src="video/video1.mp4" type='video/mp4'/>
</video>
<script type='text/javascript'>
video_count =1;
videoPlayer = document.getElementById("video");
function run(){
video_count++;
if (video_count == 3) video_count = 1;
var nextVideo = "video/video"+video_count+".mp4";
videoPlayer.src = nextVideo;
videoPlayer.play();
videoPlayer.loop();
};
</script>
This will play the files named video1.mp4 and video2.mp4... etc. Right now there is only one file in this folder called video1.mp4, and it will autoplay and it will loop. But it will fail to autoplay after a while and just show a black frame.
Any ideas?
Thanks!

I'd recommend looking into video events with javascript in this case if you're starting to see bugs.
For example (from Detect when an HTML5 video finishes post) you could start playing your next video like this:
<script type='text/javascript'>
document.getElementById('myVideo').addEventListener('ended',myHandler,false);
function myHandler(e) {
// What you want to do after the event
}
</script>
You could simply move on to the next video, or seek back to 0 on its timeline and play it again. The other option if you're wanting to loop 1 video, you'd be better using the loop option in your <video> tag:
<video loop>
<source src="video/video1.mp4" type="video/mp4">
</video>

Audio stops playing while moving to fallback mount using Icecast

I was wondering if someone has had a similar problem:
I have defined fallback mounts in Icecast2 so that one major stream plays at all times. If another fallback mount becomes active, the latter becomes the active.
I have tested the streams (mp3 format), with ffplay and the transition happens with no problem. The problem exists when I use an html5 audio tag to listen to the audio: transition does not happen automatically and I have to reload the browser and click play in order to listen to the stream. That is, using the browser, when the fallback stream gets enabled, the sound stops and I have to reload the browser and click play in order to listen[to the other stream]. The same problems occurs in all major browsers.
Here's an excerpt from my icecast.xml:
<mount>
<public>0</public>
<mount-name>/stream</mount-name>
<hidden>0</hidden>
</mount>
<mount>
<public>0</public>
<mount-name>/stream1</mount-name>
<fallback-mount>/stream</fallback-mount>
<fallback-override>1</fallback-override>
<username>stream1</username>
<password>pass</password>
<hidden>0</hidden>
</mount>
This is what ffplay shows while connecting and disconnecting from the secondary source:
The html5 code that plays the audio is as follows:
<audio controls>
<source src="http://127.0.0.1:3333/stream1" type="audio/mpeg">
</audio>

I got this finally working by going as follows:
First I noticed that when I switched from one mount point to another by enabling the source, the audio stopped playing. I set up a timer to fire every 1 second in order to check audio.currentTime and compare to an previous value. Then when the result is true, I reset the audio source to the same stream. It's kind of a hack but it seems to solve the trick.
html code:
<audio id="audio" controls>
<source src="http://127.0.0.1:3333/stream1" type="audio/mp3">
</audio>
javascript code:
var audio = document.getElementById('audio');
var myVar = setInterval(myTimer, 1000);
var oldTime = "";
function myTimer() {
if ((audio.paused != true && (audio.currentTime - oldTime) == 0 )) {
audio.src="";
audio.src="http://127.0.0.1:3333/stream1";
audio.play();
}
oldTime = audio.currentTime;
};

Maximage 2.0 - HTML5 Video random start

I started using this great plugin : http://blog.aaronvanderzwan.com/2012/07/maximage-2-0/
The problem is that when reaching a slide containing a video, sometimes it does not start (in chromium at least). No errors thrown, it just seems to be a random behavior regarding to the video loading.
Any idea if there's a way to keep firing the browser detection or to try forcing the video play with some plugin options/controls?
Also, I could not find a way to add a play button to the page to play/pause the video...

Found it, you need to get your element, and then call the play() function :
The html for the video :
<video id="vid_1" poster="http://sandbox.thewikies.com/vfe-generator/images/big-buck-bunny_poster.jpg" width="640" height="360">
<source src="http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4" type="video/mp4" />
<source src="http://clips.vorwaerts-gmbh.de/big_buck_bunny.webm" type="video/webm" />
<source src="http://clips.vorwaerts-gmbh.de/big_buck_bunny.ogv" type="video/ogg" />
Your browser does not support HTML5 videos.
</video>
Then get the video element and fire the play :
//video play button
$('.play_button').click(function(){
var video = $('video#vid_1').get(0); //get the native browser source
if (video.paused) {
video.play(); //if paused, play
}
else{
video.pause(); //if playing, pause
}
});
So basically you can call it whenever you want...

Dynamically using the first frame as poster in HTML5 video?

I'm wondering if there's any straightforward way to achieve this effect, without needing backend code to extract a frame, save it as a jpg and database it somewhere.
An effect whereby the first frame of the video just shows up as the poster when the video loads would be so helpful (it would only work if the browser can play back the video obviously, which might be a little different from how poster traditionally works, but that is not a concern.

Did you try the following?
just append time in seconds #t={seconds} to source URL:
<video controls width="360">
<source src="https://test-videos.co.uk/vids/bigbuckbunny/mp4/h264/1080/Big_Buck_Bunny_1080_10s_1MB.mp4#t=0.1" type="video/mp4" />
</video>
I have chosen a fraction of second (0.1) to keep number of frames small, because I have the suspect that if you put 1 second, it would "preload" the first 1 second of video (i.e. 24 frames or more ....). Just in case ...
Works fine on Chrome and Firefox on desktop :)
Works not on Android mobile, though :(
I did not test on iOS, iPhone, IE yet ??
Edit May 2021:
I realized that many modern browsers now show automatically a poster of first frame.
Seems like they heard us :-)

To make it simple you can just add preload="metadata" to your video tag and the second of the first frame #t=0.5 to your video source:
<video width="400" controls="controls" preload="metadata">
<source src="https://www.w3schools.com/html/mov_bbb.mp4#t=0.5" type="video/mp4">
</video>
Best of luck!

There is a Popcorn.js plugin called Popcorn.capture which will allow you to create posters from any frame of your HTML5 video.
There is a limitation that is imposed by the browser that prohibits reading pixel data of resources requested across domains (using the canvas API to record the current value of a frame). The source video must be hosted on the same domain as the script and html page that is requesting it for this approach to work.
The code to create poster using this plugin is quite simple:
// This block of code must be run _after_ the DOM is ready
// This will capture the frame at the 10th second and create a poster
var video = Popcorn( "#video-id" );
// Once the video has loaded into memory, we can capture the poster
video.listen( "canplayall", function() {
this.currentTime( 10 ).capture();
});

I recently did this for a recent project that works on desktop and mobile. The trick was getting it to work on iPhone.
Setting preload=metadata works on desktop and android devices but not iPhone.
For iPhones I had to set it to autoplay so the poster image automatically appears on initial load. iPhones will prevent the video from auto playing, but the poster image appears as the result.
I had to do a check for iPhone using Pavan's answer found here. Detect iPhone Browser. Then use the proper video tag with or without autoplay depending on the device.
var agent = navigator.userAgent;
var isIphone = ((agent.indexOf('iPhone') != -1) || (agent.indexOf('iPod') != -1)) ;
$videoTag = "";
if(isIphone()) {
$videoTag = '<video controls autoplay preload="metadata">';
} else {
$videoTag = '<video controls preload="metadata">';
}

You can set preload='auto' on the video element to load the first frame of the video automatically.

Solution for #2, #3 etc. frames. We need attach disposable handler .one() for resetting default frame.
<video width="300" height="150" id='my-video'>
<source src="testvideo.mp4#t=2" type="video/mp4" />
</video>
$(function () {
let videoJs = videojs('my-video');
videoJs.one('play', function () {
this.currentTime(0);
});
});

I found a great way to dynamically add poster to a video!
To show the desired frame from video (in my case it's the frame at 1.75 seconds) - add preload="metadata" to the video element and #t=1.75 to the end of source URL.
Add eventListener to the video element that will listen for play event only once.
Once the event is emitted reset the video time.
<video width="100%" controls="controls" preload="metadata" id="myVid">
<source src="path/to/your/video#t=1.75" type="video/mp4">
</video>
<script>
var el = document.getElementById('myVid');
el.addEventListener('play', () => {
el.currentTime = 0;
}, { once: true });
</script>
