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.

I'm looking for a way to mute sound or block it from unauthorized sources,
The problem is that Google Ads is randomly playing videos in ads (very annoying)
For example, I want users to be able to play videos on my web site (I can add a special ID to these allowed elements or data-allowed-element).
I'm wonder if I can hookup to a browser sound event or detect when sound is playing - JavaScript?
Any ideas?
No there is currently no way to detect this browser independent! - There is no event or something else.
Furthermore i dont know exactly how the Google Ads works. I think they are running in an iframe or something which make it harder to detect/mute it.
But may it runns within an audio or video tag, so you can may mute it using the following post. But be careful - You have to mute the video and audio tags within the Google Ads iframe and not within your main window, because then you will have no effect.

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);
I'm using HTML5 video tags in my webpage. I have a small "Watch Video" button that opens a modal displaying this video. Everything works as intended. I am, however, trying to determine what changes in the HTML document (or possibly the DOM?) when I hit the controller's play button.
The goal in determining this is to have the video begin playing automatically once the modal is revealed which I plan to do with a small JS script. Also, when I close the modal window, I will have it disappear.
I did a few Google searches and started to see people discussing creating custom controllers for these videos which I feel is unnecessary - I want to utilize/modify what is already in existence.
To summarize: What is happening when I hit the play/pause controllers in an HTML5 video?
The W3C has a handy <video> interface that shows how the properties and events on a video element change and fire as you interact with it.
As you can see from that demo, the major things that occur when you play a video are:
the video's paused attribute is set to false
the video emits a play event
If the video has preload value of "none" (as this one does), then the video will begin loading when the user presses play, which triggers a few other events, e.g, the canplaythrough event will eventually fire, the buffered attribute will continue to change as the video loads, etc.
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.
