Getting started with AMP
A brief guide on how to build a THEOplayer in an AMP environment.
Note that this information is for a basic player in a testing environment. Additional information may be needed for specific cases.
AMP
Accelerated Mobile Pages (AMP) is an open-source HTML framework. More information about AMP is available at https://amp.dev/.
Step-by-step guide:
- Have a valid AMP page. (Let's call this page A.)
- Prepare an embeddable page which can be served through an
<amp-iframe>. (Let's call this page B.) Read more about THEOplayer and iframes here. It's your responsibility to decide the most optimal approach for your use-case. You can use https://cdn.theoplayer.com/demos/iframe/iframe.html as a starting point to prepare your page. - Upload page B to a different (sub) domain than page A in order to adhere to the iframe origin policy.
- Embed page B into page A by using an
<amp-iframe>. It's your responsibility to decide the most optimal approach for your use-case. You can use the snippet below as an example.
<!doctype html>
<html ⚡>
<head>
<meta charset="utf-8" />
<title>amp-iframe</title>
<script async src="https://cdn.ampproject.org/v0.js"></script>
<!-- Import the amp-iframe component in the header. -->
<script
async
custom-element="amp-iframe"
src="https://cdn.ampproject.org/v0/amp-iframe-0.1.js"
></script>
<!-- You can use the `amp-bind` extension to dynamically change an iframe src. -->
<script
async
custom-element="amp-bind"
src="https://cdn.ampproject.org/v0/amp-bind-0.1.js"
></script>
<link rel="canonical" href="<% canonical %>" />
<meta
name="viewport"
content="width=device-width,minimum-scale=1,initial-scale=1"
/>
<style amp-boilerplate>
body {
-webkit-animation: -amp-start 8s steps(1, end) 0s 1 normal both;
-moz-animation: -amp-start 8s steps(1, end) 0s 1 normal both;
-ms-animation: -amp-start 8s steps(1, end) 0s 1 normal both;
animation: -amp-start 8s steps(1, end) 0s 1 normal both;
}
@-webkit-keyframes -amp-start {
from {
visibility: hidden;
}
to {
visibility: visible;
}
}
@-moz-keyframes -amp-start {
from {
visibility: hidden;
}
to {
visibility: visible;
}
}
@-ms-keyframes -amp-start {
from {
visibility: hidden;
}
to {
visibility: visible;
}
}
@-o-keyframes -amp-start {
from {
visibility: hidden;
}
to {
visibility: visible;
}
}
@keyframes -amp-start {
from {
visibility: hidden;
}
to {
visibility: visible;
}
}
</style>
<noscript
><style amp-boilerplate>

<style amp-custom>
#sample-resizable-iframe div[overflow] {
text-align: center;

line-height: 36px;
}
</style>
</head>
<body>
<amp-iframe
width="500"
height="281"
title="THEOplayer demo"
layout="responsive"
sandbox="allow-scripts allow-same-origin allow-popups"
allowfullscreen
frameborder="0"
src="https://cdn.theoplayer.com/demos/iframe/iframe.html"
>
<amp-img
layout="fill"
src="https://cdn.theoplayer.com/demos/iframe/pixel.png"
placeholder
></amp-img>
</amp-iframe>
</body>
</html>
- Once again: upload page A to a different (sub) domain than page B in order to adhere to the iframe origin policy. For example, you can put page B on https://iframe.website.com/player.html and page A on https://www.website.com/a-random-video.html
An example application of this step-by-step guide is available here.
Alternatives
Some video players offer a custom AMP tag. For example, YouTube offers this through <amp-youtube>.
Under the hood, these video players also leverage an <iframe>. Although custom AMP tags are primarily syntax sugar, it is arguably a more developer-friendly implementation than <amp-iframe>. The advantage of using <amp-iframe> is flexibility: you are in full control of the page you're embedding.
