To build a Plugin SDK* integration with JW Player, follow JW Player’s embed instructions . You must contain the JW embed code within the "p3sdk-container" div.
Make sure the ID in your player div and the player instance in your script are both identical to your player_id (highlighted in pink).
<div class="p3sdk-container p3sdk-debug" player_id="jw-player-7" player_type="jw7">
<div id="jw-player-7">Loading the player...</div>
var playerInstance = jwplayer("jw-player-7");
title: 'Basic Video Embed',
description: 'A video with a basic title and description!'
*The Plugin SDK is sometimes referred to as "P3SDK".
