Can I use javascript to dynamically change a video's source?

How can I change a video's source using JS?

<video id="myVideoTag" width="670" height="377" autoplay="true" controls="controls">
    <source src="" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'>



Sure, you can just set the src attribute on the source element:

document.querySelector("#myVideoTag > source").src = ""

Or using jQuery instead of standard DOM methods:

$("#myVideoTag > source").attr("src", ""????)?

I have run into the same problem. According to this thread:

changing source on html5 video tag

it is not possible to change the src of the source tag. you will have to use src of the video tag itself.


Although Campbell has provided the correct solution, a more complete solution to the 'playlist specific' question at hand (as noted in the comments) is provided here. This solution can be applied to all video formats if implemented correctly (I have used modernizr in order to detect which source will play for a given browser, combined with the solution above).

This solution will work (and has been tested) for changing videos in HTML5 video tags in ALL HTML5 browsers, including IE8.


This is working

<video id="videoplayer1" width="240" height="160" controls>
    <source id="video_res_1" src="" type="video/ogg">

and in the javascript

document.getElementById("video_res_1").src = "my video url.ogv";

The key is the .load() function that reloads the video player.


Check this out. This javascript changes the src of the source tag.

  function toggle() {
            if ($(this).attr('data-click-state') == 1) {
                $(this).attr('data-click-state', 0)
                document.getElementById("source").src = "";
            } else {
                $(this).attr('data-click-state', 1)
                document.getElementById("source").src = "";


i hope it should work and please adjust attribute name and id as per your need

html code below

<video controls style="max-width: 90%;" id="filePreview">                        
    <source type="video/mp4" id="video_source">

js code below

        var source = $('#video_source');
        source[0].src = URL.createObjectURL(this.files[0]);

I found that dynamically creating and appending the child source elements did the trick.

var videoElement = document.querySelector('.my-video');
var videoSources = ["video.mp4","video.webm"]
if (videoElement) {
    for (var i = 0; i < videoSources.length; i++) {
        var sourceTag = document.createElement("source");
        sourceTag.type = "video/" + videoSources[i].split('.')[1];
        sourceTag.src = videoSources[i];

I have faced this problem several times and based on previous experience and digging I can suggest these options:

  • replace video tag completely

yes, just re-insert <video> element with new sources. It's straightforward, but effective approach. Don't forget to re-initialize event listeners.

  • assign video URL to video.src

this I saw a lot in answers here, on stackoverflow, and also in sources on github.

var video = document.getElementById('#myVideo');
video.src = newSourceURL;

It works, but you cannot provide browser options to choose from.

  • call .load() on video element

according to documentation you can update src attributes for <video>'s <source> tags and then call .load() to changes take effect:

<video id="myVideo">
    <source src="video.mp4" type="video/mp4" />
    <source src="video.ogg" type="video/ogg" />

    var video = document.getElementById('myVideo');
    var sources = video.getElementsByTagName('source');
    sources[0].src = anotherMp4URL;
    sources[1].src = anotherOggURL;

Nevertheless here it's said that there're problems in some browsers.

I hope it will be useful to have this all in one place.


Since the other solutions didn't work for me, here's what I did:

 <video width="400" controls id="the_id_of_your_video_here">
  <source src="path_to_first_video.mp4" type="video/mp4">
  Your browser does not support HTML video.

<button type="button" name="button" onclick="changeVid()">Click me to change the video</button>

function changeVid(){
  var video =  document.getElementById("the_id_of_your_video_here");
  video.src = 'path_to_second_video.mp4'; // Make sure to not use ..\ like in HTML but ../ if you have to give a more complex file path like: '../../myVideoFolder/myVideo.mp4'

Nothing else is needed to get this solution running - unless I messed up somehow...
