Get SRC value from Source tag with JS

Navigation
1

I have to get the SRC value of the Source tag from this code: 

<video id="vp1_html5_FC" preload="auto" width="100%" height="100%" controls=""><source src="http://www.blogger.com/video-play.mp4?contentId=23bfbcf30d33ff96"type="video/mp4"></video>

I tried the following script: 

var el = document.getElementById("vp1_html5_FC");
var tag= el.document.getElementByTagName("source")[0].src;
alert(tag);

You do not need all this if you have only one video on the page: 

var tag= document.querySelector("video source").src;
alert(tag);
<video id="vp1_html5_FC" preload="auto" width="100%" height="100%" controls=""><source src="http://urldeexemplo.com/video=1"type="video/mp4"></video>

If you have more than one video on the page 

let tags = document.querySelectorAll("video source");
tags.forEach(function(item) {
  alert(item.src);
});
<video id="vp1_html5_FC" preload="auto" width="100%" height="100%" controls=""><source src="http://urldeexemplo.com/video=1"type="video/mp4"></video>
<video id="vp1_html5_FC" preload="auto" width="100%" height="100%" controls=""><source src="http://urldeexemplo.com/video=2"type="video/mp4"></video>
<video id="vp1_html5_FC" preload="auto" width="100%" height="100%" controls=""><source src="http://urldeexemplo.com/video=3"type="video/mp4"></video>
<video id="vp1_html5_FC" preload="auto" width="100%" height="100%" controls=""><source src="http://urldeexemplo.com/video=4"type="video/mp4"></video>
