Well, I think this is a major Youtube bug but I don't find any report about it.
I have a web app which is displayed in full screen browser using the JavaScript Fullscreen API.
In the web app there is an embedded Youtube player. When you open the Youtube player in fullscreen, then clicks the Youtube's fullscreen button again to exit the player's fullscreen, it doesn't respond!
I am sure it is related to the fact that the browser is already in full screen mode so there is some kind of conflict.
I have created a simplified example which can be viewed here:
http://run.plnkr.co/CjrrBGBvrSspfa92/
Click the "GO FULLSCREEN" button.
Play the video and click the
fullscreen button. The video will go fullscreen.
Click the
fullscreen button again. It won't exit.
EDIT:
The code for the html file above is here:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<iframe width="560" height="315" src="https://www.youtube.com/embed/b-6B2zyoFsI" frameborder="0" allowfullscreen></iframe>
<button id="btn">GO FULLSCREEN</button>
<script type="text/javascript">
document.getElementById("btn").addEventListener("click", function() {
var elem = document.documentElement;
if (elem.requestFullscreen) {
elem.requestFullscreen();
} else if (elem.msRequestFullscreen) {
elem.msRequestFullscreen();
} else if (elem.mozRequestFullScreen) {
elem.mozRequestFullScreen();
} else if (elem.webkitRequestFullscreen) {
elem.webkitRequestFullscreen();
}
});
</script>
</body>
</html>
The thing is I did some searching and it seams Youtube doesn't know if the video is in fullscreen or not when using the JavaScript Fullscreen API nor does Google provide an API call to fo in or out of fullscreen. So, When you click the button and it goes in fullscreen, you'll see the player's fullscreen button not pressed. So, in order to get back to the window view, the user has two options:
1) click on the button 2 times (the first time, the player tries to go in fullscreen and the button changes state, the second time, the player goes in window mode) - this is the solution
2) click Esc on the keyboard.
I checked with the HTML5 player.
Furthermore, I tried injecting a button inside YouTube's iframe so I can select it in order to exit fullscreen, but it didn't work... would have been silly to actually.
This should work:
<div id="videoplayer"></div>
<p><button id="btn">GO FULLSCREEN</button></p>
<script type="text/javascript">
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('videoplayer', {
height: '380',
width: '500',
videoId: 'h7ArUgxtlJs',
fs: 1
});
}
document.getElementById("btn").addEventListener("click", function() {
var elem = document.getElementById('videoplayer');
var requestFullScreen = elem.requestFullscreen || elem.msRequestFullscreen || elem.mozRequestFullScreen || elem.webkitRequestFullscreen;
if (requestFullScreen) {
requestFullScreen.bind(elem)();
}
});
</script>
You can use the classic embed, I belive.
Working demo
This may help: "Exiting Fullscreen Mode":
// Whack fullscreen
function exitFullscreen() {
if(document.exitFullscreen) {
document.exitFullscreen();
} else if(document.mozCancelFullScreen) {
document.mozCancelFullScreen();
} else if(document.webkitExitFullscreen) {
document.webkitExitFullscreen();
}
}
// Cancel fullscreen for browsers that support it!
exitFullscreen();
Source.
Side note: Youtube's API is still pretty scarce in terms of what you can customize even in 2015 (due to how it relies on so much iFrame, and they don't want you to reskin their player). You'll likely get to a point where your using a bunch of funky JavaScript hacks to get what you want, which can get messy and unstable. It would be better practice to utilize one of many customizable video players where you can have more control with JS; like JW player, Video.js, Flow player, popcorn.js etc.

I have a HTML page including Javascript which is intended to allow a video (actually just audio content in this case) to play using HTTP Live Streaming on any browser. In most cases it uses hls.js but, in the case of Apple products, I need to do things differently as Safari has native HLS support.
The full page is reproduced below but the important lines are these:
else if (video.canPlayType('application/vnd.apple.mpegurl')) {
video.src = 'music.m3u8';
video.addEventListener('canplay', startPlaying);
//document.addEventListener('DOMContentLoaded', startPlaying);
}
What should happen is that when the canplay event fires the startPlaying() function is called and this makes visible a button that the user can press to begin playing the video. However, on my friend's iPhone 8plus (iOS 11.3.1), this doesn't work: no button is ever visible. If, instead, I comment out the video.addEventListener() line and replace it with the document.addEventListener() line then it all works fine: the button is made visible and he can play the stream.
Can anyone spot what I'm doing wrong? Could be a rookey mistake as I'm not very experienced with this web/script stuff, gives me nose bleeds... I could, of course, leave it with the DOM load approach but it's not right and I'd rather be right.

}
// hls.js is not supported on platforms that do not have Media Source Extensions (MSE) enabled.
// When the browser has built-in HLS support (check using `canPlayType`), we can provide an HLS manifest (i.e. .m3u8 URL) directly to the video element through the `src` property.
// This is using the built-in support of the plain video element, without using hls.js.

From the investigations in the other question, the workaround is to wait on the event loadedmetadata, so in my case video.addEventListener('loadedmetadata', startPlaying), as this is the last event you're going to get from the HTML5 video element on Safari unless you're in the user-controlled white list. Confirmed that this works on iOS 11.3.1.
I am trying to embed a vimeo video using iframe in my Qualtrics survey. When this video ends, I want to automatically advance to the next page (i.e., automatically press the "next button"). Before using vimeo, my videos were stored on dropbox and I used the following code for this (the url is not the real one):
<video autoplay="" id="video1" height="580" width="740"><source src="https://dl.dropboxusercontent.com/u/6339921/att/fam.mp4" type="video/mp4"></video>
Qualtrics.SurveyEngine.addOnload(function() {
that = this;
document.getElementById('video1').addEventListener('ended',myHandler,false);
function myHandler(e) {
if(!e) {
e = window.event;
}
that.clickNextButton();
}
});
However, it seems that I have to use iframe with vimeo, but I am unable to make the auto-advance work (the video will play but the page will not advance). Maybe it is because I am assigning the "ID" the wrong way. Here is the code:
<iframe id="player1" src="https://player.vimeo.com/video/20708824?autoplay=1api=1&player_id=player1&title=0&byline=0&portrait=0&background=1&mute=0&loop=0" width="600" height="400" frameborder="0"></iframe>
Qualtrics.SurveyEngine.addOnload(function() {
that = this;
var idPlayer = new Vimeo.Player('player1');
document.getElementByID('player1').addEventListener('ended',myHandler,false);
function myHandler(e) {
if(!e) { e = window.event; }
that.clickNextButton();
}
});
I am looking for a) an option to fix the iframe code, or b) an option to embed a vimeo video using the old code that I had used with dropbox videos.
Thanks so much and I apologize if this all sounds naive, I am not a programmer :-(
You can't add an event listener to an iframe from a different domain. It is called cross-domain scripting and for security reasons isn't allowed by the browser.
You have to use postMessage. There is a JavaScript class already written, but you would have figure out how to integrate it into Qualtrics:
https://github.com/vimeo/player.js
I'm using Vimeo player's JavaScript API for starting a video when a user clicks on the specific button on the site.
Here's the embedded code:
<iframe id="vimeo-player" src="<?php the_sub_field('slide_video'); ?>?title=0&byline=0&portrait=0" width="1880" height="1058" frameborder="0" ></iframe>
Here's the JavaScript:
var iframe = document.querySelector('#vimeo-player');
var player = new Vimeo.Player(iframe);
$('.slide-area__slides__video svg').click(function(){
$(this).hide();
$(this).closest('.item').find('img').hide();
$(this).siblings('iframe').show();
player.play();
});
player.on('ended', function(data) {
$('.slide-area__slides__video svg').show();
$('.slide-area__slides__video iframe').hide();
$('.slider-area__slides .item img').show();
});
It works perfectly in Chrome, but in every other browser, it just keeps throwing the error:
The player element passed isn’t a Vimeo embed.
Has anyone encountered this before? It's quite frustrating.
Looking at player.js, it seems that the error displays when:
if (element.nodeName === 'IFRAME' && !isVimeoUrl(element.getAttribute('src') || '') {...}
Make sure the_sub_field('slide_video') outputs a valid Vimeo URL.
I'm working on a website, and i'm trying to get an youtube video in an <iframe> tag to play and pause with one button. I can get it to play or pause with separate buttons, but I can't seem to get the if statement to work in order to control the video with just one button.
I'm still relatively new to JavaScript, so it may just bee something simple I missed, but I'v searched online for a while now, and could not find anything that solved my problem.
Below is the code I use right now. The first time I click the button the YouTube video play's, but the second time nothing happens.
I also tried turning autoplay on for the embedded video, but then when I press the button, nothing happens at all.
This is the code I'm currently using:
HTML
<div class="iframe">
<iframe id="iframe1" width="360" height="203" src="https://www.youtube-nocookie.com/embed/videoseries?list=PLb-Mg8r29XuOV9CbkXVDQ5NdQG__WbJqI&controls=0&showinfo=0&enablejsapi=1" frameborder="0" allowfullscreen></iframe>
<a href="#" onclick="iframe1play();return false;">
<div id="iframe1play">
</div>
</a>
</div>
JavaScript
function onYouTubePlayerAPIReady() {
iframe1 = new YT.Player('iframe1');
}
function iframe1play() {
if (event.data == YT.PlayerState.PLAYING && !done) {
iframe1.pauseVideo();
document.getElementById("iframe1").style.opacity = "0";
} else {
iframe1.playVideo();
document.getElementById("iframe1").style.opacity = "1";
}
}
var tag = document.createElement('script');
tag.src = "//www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
Any suggestions are appreciated!
Ok so the main problem was that you didn't have event object in your function.
this should do the trick
if (player.getPlayerState() == YT.PlayerState.PLAYING) {
player.pauseVideo();
document.getElementById("iframe").style.opacity = "0";
} else {
player.playVideo();
document.getElementById("iframe").style.opacity = "1";
}
Use jQuery or other framework, if you can,for injecting functions to elements.
Maybe I don't understand your question. Because I tried your code and it works.
I can see a page with a youtube video. On clicking play button the video starts and when I click again on the video in pauses. So what is your problem. I'm sorry if I don't use comments but I can't yet.
I am trying to prevent the default scrolling within a web app which contains an HTML5 video element on Mobile Safari. Handling document.ontouchmove and calling e.preventDefault() has been the standard way that I've found to achieve this.
This seems to work everywhere except when you touch on top of the video element, where you can start pulling the page all around as if it is going to scroll. This only seems to happen when the native video controls are forced on. If you don't include the controls attribute and load the video in a way that it can be played in-line (such as on the iPad or in a UIWebView with allowsInlineMediaPlayback set), scrolling is prevented properly. So it seems like it has something to do with the native video controls (the big play button) capturing the event.
Here is a contrived example of what I am doing:
<!DOCTYPE HTML>
<html>
<head>
<title>HTML5 Video Example</title>
<meta name="viewport" content="width=device-width,initial-scale=1.0,user-scalable=no">
</head>
<body style="background: blue;">
<video src="http://cdn.kaltura.org/apis/html5lib/kplayer-examples/media/bbb_trailer_iphone.m4v" controls></video>
<script>
window.onload = function() {
document.ontouchmove = function(e) {
e.preventDefault();
}
}
</script>
</body>
</html>
Any ideas of workarounds to completely prohibit scrolling behavior, even on the video? I've already tried handling ontouchmove directly on the video element and it doesn't work.
Thanks!
In my test, when ommiting the "controls" attribute of the video you can get the events to work. Use a custom div in top to provide custom controls
By example....
<video src="http://192.168.1.53/videoTester/Cuatro.mp4" id="player" width="100%" height="100%" x-webkit-airplay="allow" ></video>
Like you, I couldn't prevent scrolling, so as a workaround added a JS function to fire window.scrollTo(0, 1); every second which then means the user can only scroll for a certain time before the page is jumped back.
Try:
element.addEventListener('touchmove', function(event) {
// Prevent scrolling on this element
event.preventDefault();
}, false);
for just the element in question or:
window.addEventListener('touchmove', function(event) {
// Prevent scrolling on this element
event.preventDefault();
}, false);
for the whole window.
I came up with a good solution for this after running into the same issue. I got it to work by doing the following:
//Function to trigger when every half second to check if user scrolled
$(function () {
//select video player and the current time
var myPlayer = document.getElementById('VideoID');
var whereYouAt = myPlayer.currentTime;
var current;
setInterval(function () {
current = myPlayer.currentTime;
if (current > (whereYouAt + 1)) {
myPlayer.currentTime = whereYouAt; //If current 1 whole second
//Set time to before scroll.
}
else {
whereYouAt = current; //otherwise set where to current.
}
}, 500); //500 = half a second.
});
This will only work for HTML5 video and not if it triggers the mobile video player. I hope this helps and let me know if you have any questions.
