I have read that autoplay was not possible, or not advised on both iOS and Android (more on that here: no autoplay in iframe HTML5 player on mobile (Android Chrome and Firefox)?). But I was wondering if there was a way that would allow to replicate the same behavior, that is the video playing soon as the page is loaded.
I have tried preloading the video, and playing it once the DOM is loaded, I tried forcing a play soon as the video can be played, none of that work, it always result in the user having to tap the video to play it.
Can anyone help?
NB: I'm working with plain old JavaScript, no jQuery.
No, there is no way on iOS/Safari (or iBooks).
Videos load only in the context of an event handler reacting to user action such as a touch.
You're out of luck.
This has been documented extensively in any number of questions right here on SO, and is clearly documented by Apple.

Many browsers have policies that block autoplaying videos. See for example: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes
Let's say there is a workflow similar to the following (I know it seems contrived, but it's the best option at this point, I can go into detail why if anyone is curious):
User clicks on an iframe video to play it.
The iframe sets a cookie to set it to play after an iframe refresh (window.location.reload())
On reload, the player reads the cookie, and plays the video.
Would any browsers see this as an autoplay and potentially block the video from playing? Or would they recognize the iframe as having been interacted with, and not block this playback?
I'm mostly curious about Safari, though other browsers like Firefox and Chrome would be of interest as well.
Thank you!
Since the YouTube API has no means of programmatically triggering fullscreen (apparently for good reasons, relating to legacy Flash support, as described here), I'm getting by just by using the HTML5 Element.requestFullscreen API to fullscreen the player IFrame.
Unfortunately, if a user triggers fullscreen in the YouTube player, then the player itself goes fullscreen instead of the IFrame, and doesn't produce any events to signal that it has done so. That breaks my UI and causes other synchronization problems when the rest of the application doesn't know what things are and are not fullscreen anymore. A partial solution is to use the chromeless player and then render my own player controls, so that users can't click the YouTube fullscreen button- but, it turns out that double clicking on a YouTube video will also cause it to enter fullscreen mode, again with no way of signalling the rest of the application that it has done so.
So, is there any consistent way of preventing an embedded YouTube player from going fullscreen under any circumstances, without impacting other functionality?
The best solution I have so far is to set pointer-events:none on the iframe. That's not quite perfect, however, as it also makes it impossible to dismiss ad banners displayed over YouTube videos. An ideal solution would block the "fullscreen on double-click" response, without messing up anything else. (Single-click to play, for example, is just fine, because the YouTube player does emit play events that let me keep the rest of the application in-sync.)
When embedding using the iframe tag, you can use the parameter fs = "0" to disable to the fullscreen button. See http://codepen.io/anon/pen/zvOqKJ
There is something weird going on with this. I was unable to prevent fullscreen when I passed in "fs: 0" with the playerVars as per this page
https://developers.google.com/youtube/player_parameters?playerVersion=HTML5
(even though some other player vars were making a difference)
God knows what's wrong, but I fixed it with:
var ourYT = document.getElementById('player');
ourYT.allowFullscreen = false;
Use this;
iframe {pointer-events: none;}
you can disabling click events on youtube player (play,pause,fullscreen);
Is it possible to make an external play button for a video without the play button in the video?
For example when you want to start a youtube video you see a red button in the middle of it. I want that hidden and a button outside of the video to start the video. It doesn't matter what video player it is.
I want to do this because iPad does not allow autoplay. And using the external button I want to trick it to autoplay.
This is a website that does "autoplay" on the iPad.

There is a reason why YouTube doesn't allow autoplay on mobile/tablet devices, video's use up alot of bandwith which may become expensive for the user.
U can trick it like u mentioned with a custom play button or even force it to start playing without a custom button. There is alot of detailed information on YouTube's API page.
Check out this page: https://developers.google.com/youtube/
I'd refrain from always autoplaying a video though if not just for bandwith reasons. In your case u could check if the device is a tablet.
I finally found an answer for this using HTML5 videos. It allows me to use the control buttons externally so I can use an overlay and hide the overlay when the play button is clicked so it will seem like it is auot played.
I'm trying to get it understand but after 2 days of digging the code I thought that I will post my issue here...
According to Apple's documentation, autoplaying videos on iOS devices cannot be done without user interaction first (e.g. tap on video). Despite that, mobile YouTube (m.youtube.com) is able to autoplay its videos just after loading a page with video.
Does anyone know how they are doing it?
PS. I've checked all available JS/HTML techniques of autoplaying videos on website on iOS (e.g. iframe, fake click, triggering touch event on video, fetching video with XHR).
I believe that youtube.com is a single page app. So when the user clicks on the video from the list view the page is not loading and their javascript uses that initial click, that leads to the video page, as the click that starts the video. It's not actually autoplaying, it's just a trick.
I am creating an iPad app for running YouTube video using IFrame.
I referred to many questions regarding YouTube integration in UIWebView and understand that:
Autoplay is not possible
Apple doesn't allow to run video without user interaction (starting).
In my simple app, I have a JavaScript button in the first page, and in the next page integrated YouTube with IFrame.
If I click on the JavaScript button, is there any way to pass this click event to the next page for running YouTube?
Is event bubbling in HTML helps this?
As far as I know no, you can't do anything about it. Event triggering can be easily simulated (some example) without user interaction which can't work on iOS devices (because of the policy you mentioned).
iOS video tag (used by YouTube in this case) is handled by iOS browser. Mobile version is showing placeholder with play button which you need to 'tap'. And only this action can play the video. Notice that you can't even overlay video tag with anything, because it will simply not work.
