Angular CLI RTMP Video player not working

I've been trying to stream a rtmp video on Angular, but for some reason it doesn't work

my code is

<link href="http://vjs.zencdn.net/5.19.2/video-js.css" rel="stylesheet">
<script src="http://vjs.zencdn.net/ie8/1.1.2/videojs-ie8.min.js"></script>
<video id="my-video" class="video-js" controls preload="auto" width="640" height="264" data-setup="{}">
  <source src="video_rtmp_url" type="rtmp/mp4">
</video>
<script src="http://vjs.zencdn.net/5.19.2/video.js"></script>

The result I get is this:

Obs: I've ran the "npm install --save videojs" command Obs²: i'm using ruby on rails on the background, there's no direct relation between it and the video player yet, but on the rails views, the exact same code works fine Obs³: There's no error or something related on the console

Besides that, what are the other options to stream RTMP on Angular?

Thanks!
