JS play button for HTML5 does not work on iOS mobile

I'm trying to get an HTML5 video to play on mobile iOS. Desktop & android work fine.
Clicking the button enters fullscreen mode and plays the video.
I'm seeing reports that some cannot click the button at all though the video thumbnail is loading. The breakdown is currently:
iOS 16.0.2 not working
iOS 15.2.1 works using safari but not firefox or chrome

brimmingVideo.addEventListener('mozfullscreenchange', brimmingexitHandler, false);
brimmingVideo.addEventListener('MSFullscreenChange', brimmingexitHandler, false);
brimmingVideo.addEventListener('webkitfullscreenchange', brimmingexitHandler, false);
`

Three things are causing this problem:
At javascript, removing return false; of the event listener.
At the stylesheet, the element which calls the action must have the property cursor: pointer;. Probably Apple put this requirement in these calls for best feedback on a user interface.
Again at the stylesheet, we can't set display: none; for hidden input because some browsers don't accept clicks on elements that aren't displayed. (This doesn't apply for you)
Also, the general rule is to "grab" DOM elements only after DOM was loaded!

run 2 html video side by side at the same time JS

I would like to play 2 html video exactly at the same time (side-by-side).
I made a button which has a click EventListener on it. This listener trigger the 2 <video> tag to play it, but I think there is 150 ms a delay at the second play trigger.
index.html
<section>
<video src="source1" id="video1"></video>
<video src="source2" id="video2"></video>
<button id="play">Play</button>
</section>
and here is the basic script.js file.
const $video1 = document.getElementById('video1');
const $video2 = document.getElementById('video2');
const $play = document.getElementById('play');
const playVideo = () => {
$video1.play();
$video2.play();
};
$play.addEventListener('click', playVideo);
These 2 videos are almost the same, except the first video size is about 12MB and the other one is around 20MB
What I tried:
Tried to add a console.time('video') that could logs the delay between each play function call, but that can be different in each environment.

The only way I'm aware of about playing video in sync is to emit a custom event to sync the video in requestAnimationFrame:
var videos = {
a: Popcorn("#a"),
b: Popcorn("#b"),
},
scrub = $("#scrub"),
loadCount = 0,
events = "play pause timeupdate seeking".split(/\s+/g);
// iterate both media sources
Popcorn.forEach(videos, function(media, type) {
// when each is ready...
media.on("canplayall", function() {
// trigger a custom "sync" event
this.emit("sync");
// set the max value of the "scrubber"
scrub.attr("max", this.duration());
// Listen for the custom sync event...
}).on("sync", function() {
// Once both items are loaded, sync events
if (++loadCount == 2) {
// Iterate all events and trigger them on the video B
// whenever they occur on the video A
events.forEach(function(event) {
videos.a.on(event, function() {
// Avoid overkill events, trigger timeupdate manually
if (event === "timeupdate") {
if (!this.media.paused) {
return;
}
videos.b.emit("timeupdate");
// update scrubber
scrub.val(this.currentTime());
return;
}
if (event === "seeking") {
videos.b.currentTime(this.currentTime());
}
if (event === "play" || event === "pause") {
videos.b[event]();
}
});
});
}
});
});
scrub.bind("change", function() {
var val = this.value;
videos.a.currentTime(val);
videos.b.currentTime(val);
});
// With requestAnimationFrame, we can ensure that as
// frequently as the browser would allow,
// the video is resync'ed.
function sync() {
if (videos.b.media.readyState === 4) {
videos.b.currentTime(
videos.a.currentTime()
);
}
requestAnimationFrame(sync);
}
sync();

UPDATE
Both of the answers was correct.
What I didn't know, that one of the video file has sound, and the other don't. That caused the 150ms delay.
Solved it with ffmpeg. Create an .mp3 file with the sound (and play it with <audio>), and 2 .mp4 files without sound.
They are playing exactly at the same time now.

I will also add this link here, as evident someone had a very similar problem, albeit with audio
Run function after audio is loaded
It appears you are looking for this event listener "canplaythrough", check more in the link.
function checkAudio() {
audioElem.setAttribute("src", audioFile);
audioElem.addEventListener('canplaythrough', (event) => {
resultScreen.innerHTML = "loaded audio";
});
}

How can I track HTML5 Video Control event?

I'm trying to track the event of an HTML5 Video, specifically the pause/play on the default control bar (for non-mobile Chrome and Safari).
Here's my test code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Video Test</title>
</head>
<body>
<video id="video" width="320" height="240" src="http://www.w3schools.com/tags/mov_bbb.mp4" controls>
<source src="http://www.w3schools.com/tags/mov_bbb.mp4" type="video/mp4">
</video>
<script>
var video = document.getElementById("video");
video.onclick = function(){
if(!this.paused) {
this.pause();
console.log("paused");
} else {
this.play();
console.log("playing");
}
}
</script>
</body>
</html>
If I toggle play/pause in the center of the video, the event fires just fine.
The problem is that when I click the Pause/Play button on the default control bar (lower left), although the video pauses/plays, the log does not display (I assume the event does fire since it pauses/plays).
I've not found a reason for the log to not display and was hoping someone to point me in the right direction.
In my actual code, depending on whether the video is paused or played, a timer function will be called (or killed).
Thanks.

Your adding the onclick event to pause and resume the video but you're not handling the pause and playing events. Those events are triggered when you pause an play from the control bar.
This is how I would do it:
var video = document.getElementById("video");
function StartPauseHandler(e) {
if (e.type === "pause") {
console.log("paused");
} else if (e.type === "playing") {
console.log("playing");
} else {
if(!this.paused) {
this.pause();
} else {
this.play();;
}
}
}
video.addEventListener("click", StartPauseHandler);
video.addEventListener("pause", StartPauseHandler);
video.addEventListener("playing", StartPauseHandler);

play/pause video onclick firefox

I want videos to play/pause when you click on them. Firefox has this behaviour by default. Chrome does not. The simple solution I came up with was setting a click event with jQuery.
var video = $('#myVideo');
var videoDomObj = video.get(0);
//click event for the video itself
video.on('click', function(e){
//when video is clicked it should be paused when playing and vise versa
if (videoDomObj.paused){
videoDomObj.play();
} else{
videoDomObj.pause();
}
});
jsfiddle
This will work in IE and Chrome. However, this will result in a conflict in Firefox, since it will instantly call the default event afterwards and will not play the video at all. e.preventDefault() fixes this problem, but will break all the other controls in Firefox. While they still work, they will play/pause the video. Is there an easy solution for this?

In fact the raw code worked like a charm:
document.getElementById('myVideo').onclick = function(e) {
e.preventDefault();
if (this.paused){
this.play();
} else{
this.pause();
}
}
The jQuery equivalent should be:
jQuery('#myVideo').on('click', function(e) {
e.preventDefault();
if (this.paused){
this.play();
} else{
this.pause();
}
});
But as you said that breaks the video controlls, desired and simplest solution for this could be selecting a parent element (or adding a container, if required):
var video = document.getElementById('myVideo');
video.parentElement.onclick = function(e) {
if (video.paused){
video.play();
} else{
video.pause();
}
}
jQuery:
var $video = jQuery('#myVideo'), video = $video.get(0);
$video.parent().on('click', function(e) {
if (video.paused){
video.play();
} else{
video.pause();
}
});

The only solution I found was to detect the browser for this special case, since the problem only occurs in firefox and it has this feature by default anyway.
jsfiddle
//jQuery video element
var video = $('#myVideo');
//DOM element for HTML5 media events
var videoDomObj = video.get(0);
//detect if firefox
var is_firefox = navigator.userAgent.toLowerCase().indexOf('firefox') > -1;
//only bind click event if not firefox to prevent broken controls - firefox pauses/plays videos on click by default anyway
if (!is_firefox){
video.on('click', function(e){
//when video is clicked it should be paused when playing and vise versa
if (videoDomObj.paused){
videoDomObj.play();
} else{
videoDomObj.pause();
}
});
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<video id="myVideo" width="100%" controls>
<source src="http://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4">
Your browser does not support HTML5 video.

Detect if HTML5 Video element is playing [duplicate]

This question already has answers here:
How to tell if a <video> element is currently playing?
(7 answers)
Closed 1 year ago.
I've looked through a couple of questions to find out if an HTML5 element is playing, but can't find the answer. I've looked at the W3 documentation and it has an event named "playing" but I can't seem to get it to work.
This is my current code:
var stream = document.getElementsByTagName('video');
function pauseStream() {
if (stream.playing) {
for (var i = 0; i < stream.length; i++) {
stream[i].pause();
$("body > header").addClass("paused_note");
$(".paused_note").text("Stream Paused");
$('.paused_note').css("opacity", "1");
}
}
}

It seems to me like you could just check for !stream.paused.

Check my answer at How to tell if a <video> element is currently playing?: MediaElement does not have a property that tells if it is playing or not. But you could define a custom property for it.
Object.defineProperty(HTMLMediaElement.prototype, 'playing', {
get: function(){
return !!(this.currentTime > 0 && !this.paused && !this.ended && this.readyState > 2);
}
})
Now you can use it on video or audio elements like this:
if(document.querySelector('video').playing){
// Do anything you want to
}

Note : This answer was given in 2011. Please check the updated documentation on HTML5 video before proceeding.
If you just want to know whether the video is paused, use the flag stream.paused.
There is no property for a video element in getting its playing status. But there is one event "playing" which will be triggered when it starts to play. An Event called "ended" is also triggered when it stops playing.
So the solution is:
Declare one variable videoStatus.
Add event handlers for different events of video.
Update videoStatus using the event handlers.
Use videoStatus to identify the status of the video.
This page will give you a better idea about video events. Play the video on this page and see how the events are triggered.
http://www.w3.org/2010/05/video/mediaevents.html

jQuery(document).on('click', 'video', function(){
if (this.paused) {
this.play();
} else {
this.pause();
}
});

Add eventlisteners to your media element. Possible events that can be triggered are: Audio and video media events

var media = document.getElementById('myVideo');
// Playing event
media.addEventListener("playing", function() {

});

media.addEventListener("pause", function() {

});
// Seeking event
media.addEventListener("seeking", function() {
$("#output").html("Seeking event triggered");
});
// Volume changed event
media.addEventListener("volumechange", function(e) {
$("#output").html("Volumechange event triggered");
});
</script>
</body>
</html>

Best approach:
function playPauseThisVideo(this_video_id) {
var this_video = document.getElementById(this_video_id);
if (this_video.paused) {
console.log("VIDEO IS PAUSED");
} else {
console.log("VIDEO IS PLAYING");
}
}

I encountered a similar problem where I was not able to add event listeners to the player until after it had already started playing, so #Diode's method unfortunately would not work. My solution was check if the player's "paused" property was set to true or not. This works because "paused" is set to true even before the video ever starts playing and after it ends, not just when a user has clicked "pause".

You can use 'playing' event listener =>
const video = document.querySelector('#myVideo');
video.addEventListener("playing", function () {
// Write Your Code
});

Here is what we are using at http://www.develop.com/webcasts to keep people from accidentally leaving the page while a video is playing or paused.
$(document).ready(function() {
var video = $("video#webcast_video");
if (video.length <= 0) {
return;
}
window.onbeforeunload = function () {
var htmlVideo = video[0];
if (htmlVideo.currentTime < 0.01 || htmlVideo.ended) {
return null;
}
return "Leaving this page will stop your video.";
};
}

a bit example
var audio = new Audio('https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3')
if (audio.paused) {
audio.play()
} else {
audio.pause()
}

I just looked at the link #tracevipin added (http://www.w3.org/2010/05/video/mediaevents.html), and I saw a property named "paused".
I have ust tested it and it works just fine.

This is my code - by calling the function play() the video plays or pauses and the button image is changed.
By calling the function volume() the volume is turned on/off and the button image also changes.
function play() {
var video = document.getElementById('slidevideo');
if (video.paused) {
video.play()
play_img.src = 'img/pause.png';
}
else {
video.pause()
play_img.src = 'img/play.png';
}
}
function volume() {
var video = document.getElementById('slidevideo');
var img = document.getElementById('volume_img');
if (video.volume > 0) {
video.volume = 0
volume_img.src = 'img/volume_off.png';
}
else {
video.volume = 1
volume_img.src = 'img/volume_on.png';
}
}

I just did it very simply using onpause and onplay properties of the html video tag. Create some javascript function to toggle a global variable so that the page knows the status of the video for other functions.
Javascript below:
// onPause function
function videoPause() {
videoPlaying = 0;
}
// onPause function
function videoPlay() {
videoPlaying = 1;
}
Html video tag:
<video id="mainVideo" width="660" controls onplay="videoPlay();" onpause="videoPause();" >
<source src="video/myvideo.mp4" type="video/mp4">
</video>
than you can use onclick javascript to do something depending on the status variable in this case videoPlaying.
hope this helps...

My requirement was to click on the video and pause if it was playing or play if it was paused. This worked for me.
<video id="myVideo" #elem width="320" height="176" autoplay (click)="playIfPaused(elem)">
<source src="your source" type="video/mp4">
</video>
inside app.component.ts
playIfPaused(file){
file.paused ? file.play(): file.pause();
}

var video_switch = 0;
function play() {
var media = document.getElementById('video');
if (video_switch == 0)
{
media.play();
video_switch = 1;
}
else if (video_switch == 1)
{
media.pause();
video_switch = 0;
}
}

I just added that to the media object manually
let media = document.querySelector('.my-video');
media.isplaying = false;
...
if(media.isplaying) //do something
Then just toggle it when i hit play or pause.

a bit example when playing video
let v = document.getElementById('video-plan');
v.onplay = function() {
console.log('Start video')
};
