Videojs - unique video id

Nuevo plugin features an option to set unique id for the current media file. This is also the case of multiple videos included in nuevo playlist.
Unique video id is required when using nuevo resume option. Video id is also useful to identify video for media tracking events.
A unique video id is possible to set in several ways:

1. As video source tag parameter:
   Code snippet

   <video id="my_player" class="video-js vjs-fluid" preload playsiniline>

   <source src="//path-to-video-playlist.m3u8" type="application/x-mpegURL" video_id="your-unique-id">

   </video>
2. When setting up video source through javascript:
   Code snippet

   player.src({ src:"//path-to-video-playlist.m3u8" type:"application/x-mpegURL" video_id:"your-unique-id"});
3. As nuevo plugin option:
   Code snippet

   player.nuevo({ video_id: "your-unique-id", title: "video title" });
To get current video_id use simple function:
Code snippet
var video_id = player.video_id();
