video.js - update video source when clicking on a link
I am trying to have a page with embedded video that dynamically will change the source when a link below the video frame is clicked. The source videos are on my host server. i.e. this pic illustrates it:
![sample of page][1]
I came across this page, which seems to have the answer, but I tried it and it didn't work. Following the example, I pasted the css & javascript in the and the necessary html in the body. I updated all the references to my urls and tried to keep file names the same as the example for testing. Below is what I tried.
Can someone point out my errors, or provide a more elegant way of doing this? Basically dynamically change embedded video when link is clicked and the video work in all the typical browsers, and most devices.
This is for a wordpress site, using JW Player for wordpress, (my error) instead I found this script/code is actually for Video.js
It loads the pre image but doesn't play.
As a test I tried this and it does play single video properly:
<video id="testvideo" class="video-js vjs-default-skin" width="440" height="300" controls="controls">
<source src="http://www.mywebsite.net/videos/testvid_01.mp4" type="video/mp4"/>
<source src="http://www.mywebsite.net/videos/testvid_01.webm" type="video/webm"/>
<source src="http://www.mywebsite.net/videos/testvid_01.ogv" type="video/ogg"/>
</video>
The javascript version for multiple source links
<html>
<head>
<title></title>
<style media="screen" type="text/css">
.wrap { margin:30px auto 10px; text-align:center }
.container { width:440px; height:300px; border:5px solid #ccc }
p { font: 10px/1.0em 'Helvetica',sans-serif; margin:20px }
</style>
<script>
$("input[type=button]").click(function() {
var $target = "testvid_"+$(this).attr("rel");
var $content_path = "http://www.mywebsite.net/videos/";
var $vid_obj = _V_("div_video");
// hide the current loaded poster
$("img.vjs-poster").hide();
$vid_obj.ready(function() {
// hide the video UI
$("#div_video_html5_api").hide();
// and stop it from playing
$vid_obj.pause();
// assign the targeted videos to the source nodes
$("video:nth-child(1)").attr("src",$content_path+$target+".mp4");
$("video:nth-child(1)").attr("src",$content_path+$target+".ogv");
$("video:nth-child(1)").attr("src",$content_path+$target+".webm");
// replace the poster source
$("img.vjs-poster").attr("src",$content_path+$target+".png").show();
// reset the UI states
$(".vjs-big-play-button").show();
$("#div_video").removeClass("vjs-playing").addClass("vjs-paused");
// load the new sources
$vid_obj.load();
$("#div_video_html5_api").show();
});
});
$("input[rel='01']").click();
</script> </head>
<body>
<section class="container wrap">
<video id="div_video" class="video-js vjs-default-skin" controls preload="auto" width="440" height="300" poster="http://www.mywebsite.net/videos/testvid_01.png" data-
setup="{}">
<source src="" type="video/mp4">
<source src="" type="video/ogg">
<source src="" type="video/webm">
</video>
</section>
<div class="wrap">
<input rel="01" type="button" value="load video 1">
<input rel="02" type="button" value="load video 2">
<input rel="03" type="button" value="load video 3">
</div>
</body>
</html>
The preload image for the 1st video loads but no video, error is "No video with supported format and MIME type found"
So I added the source for the first video in this section
setup="{}">
<source src="http://www.mywebsite.net/videos/videos/testvid_01.mp4" type="video/mp4">
<source src="http://www.mywebsite.net/videos/videos/testvid_01.ogv" type="video/ogg">
<source src="http://www.mywebsite.net/videos/videos/testvid_01.webm type="video/webm">
</video>
Result the 1st video loads but not the other linked videos.
names of the videos/png: testvid_01.mp4, testvid_01.ogv, testvid_01.webm, testvid_01.png testvid_02.mp4, testvid_02.ogv, testvid_02.webm, testvid_02.png testvid_03.mp4, testvid_03.ogv, testvid_03.webm, testvid_03.png
I have tried this both in wordpress page and html page the results are the same.
I'm not sure even if this script will do what I want?
Answer
This overwrites the video element's src attribute three times, so it will always be set to the webm video.
$("video:nth-child(1)").attr("src",$content_path+$target+".mp4");
$("video:nth-child(1)").attr("src",$content_path+$target+".ogv");
$("video:nth-child(1)").attr("src",$content_path+$target+".webm");
Instead use the video.js API to load an array of sources so video.js can pick one the current playback tech can play:
$vid_obj.src([
{ type: "video/mp4", src: $content_path+$target+".mp4" },
{ type: "video/webm", src: $content_path+$target+".webm" },
{ type: "video/ogg", src: $content_path+$target+".ogv" }
]);
