Safari HTML5 custom video controller with Picture In Picture (PiP)

At the WWDC15 Apple introduces Safari 9 (Safari 10 for MacOS), there now have support for Picture in Picture.

However, they just say:

If you use custom HTML5 video controls, you can add Picture in Picture functionality using the JavaScript presentation mode API.

but not telling how or where to find its documentation.

The default video controller has the button, but how do I trigger it by javascript?

Add a Picture-in-Picture Element to Your Markup

The custom controls now include markup for a new picture-in-picture button, which is visible by default.

Listing 1 This markup adds a picture-in-picture button

<video id="video" src="my-video.mp4"></video>
<div id="controls">
    <button id="pipButton">PiP</button>
</div>

Add Functionality to the Button

Add a function to toggle Picture in Picture using the webkitSetPresentationMode property from the presentation mode API.

Listing 2 This code toggles Picture in Picture using a click event listener.

var video = document.getElementById('video');
var PiP = document.getElementById('pipButton');

// picture-in-picture
if (video.webkitSupportsPresentationMode && typeof video.webkitSetPresentationMode === "function") {
    // Toggle PiP when the user clicks the button.
    PiP.addEventListener("click", function(event) {
            video.webkitSetPresentationMode(video.webkitPresentationMode === "picture-in-picture" ? "inline" : "picture-in-picture");
    });
 } else {
    PiP.disabled = true;
 }

In action.

var video = document.getElementById('video');
var PiP = document.getElementById('picture-in-picture');

// return false if it is a computer OS
var isMobile = navigator.userAgent.match(/(iPhone|iPod|iPad|Android|webOS|BlackBerry|IEMobile|Opera Mini)/i) || false;

if (isMobile[0] == 'iPad' || isMobile == false) {
    // picture-in-picture
    if (video.webkitSupportsPresentationMode && typeof video.webkitSetPresentationMode === "function") {
        // Toggle PiP when the user clicks the button.
        PiP.addEventListener("click", function(event) {
            video.webkitSetPresentationMode(video.webkitPresentationMode === "picture-in-picture" ? "inline" : "picture-in-picture");
        });
    } else {
        PiP.disabled = true;
    }
} else {
    PiP.disabled = true;
}

Only works in Safari 10+<br>
