I am testing a script that would essentially let me pull the video source URL through ajax and change the video source to try to hide the source of my video files from users (basically dont want people downloading my content).
I have no issues getting the ajax to work, but the "replaceChild" command doesnt seem to be doing anything for me. I stripped out all the ajax and tried to run a basic function calling this command with "alerts" along the way to show me what is working and what is not, it appears to me that the replaceChild command is not working.
Can anyone spot any issues with my code or offer alternate solutions?

<script type="text/javascript">
function testFunction(){
var video = document.getElementById("video2").getElementsByTagName("source")[0];
var source = "realvideo.mp4";
clone = video.cloneNode(true);
alert(clone.src);
clone.setAttribute("src",source);
alert(clone.src);
video.parentNode.replaceChild(clone,video);
alert(video.src);
}
</script>

<body onLoad="testFunction()">
<div align="center">

<div>
<video id="video2" class="video-js vjs-big-play-centered" controls preload="auto" width="640" height="264" poster="realvideo.jpg">
<source src="sorry.mp4" type="video/mp4">
</video>
</div>
</body>
</html>
That code alerts "sorry.mp4", "realvideo.mp4", "sorry.mp4"
This is expected behaviour. When you call:
video.parentNode.replaceChild(clone,video);
video will not suddenly become a different element. It will still have the same src attribute as before. video is detached from the document by the above replaceChild call, and clone is injected in its stead... it's an in/out swap. So you should not expect that video still references the element in the document and becomes the same reference as clone.
To really verify the change you could end your function with this code:
video = document.getElementById("video2").getElementsByTagName("source")[0];
alert(video.src);

I need to show multiple instances of a video tag on one page. I'm trying to find a way to read video buffers and use MediaStream to append the buffers to another video tag. But it seems there is no such an api in video tag.
Is there any way to do this? please let me know if you know any solutions.
NOTE: I don't want to use canvas to put image data on it because of performance issues in safari.
"I need to show multiple instances of a video tag on one page...
But it seems there is no such an api in video tag."
You can try using the CaptureStream API (intro). You can also check options in the documentation.
CaptureStream should not care if your video input is a media file or some appended buffers.
Note: In these stream copies...
autoplay is needed for auto-displaying pixels,
muted avoids hearing multiple audios.
This code is tested as working in Chrome (Windows), so let's hope it works in Safari (Apple) too:

I have a WordPress site with a page containing a video; I'd like this video to play automatically when the page is visited, and once the video has finished playing, I'd like a redirect to happen to a different page on my site.
I've followed the instruction from this post:
Redirect html5 video after play
But this doesn't seem to work for me and I can't figure out what I should do differently.
Here's the code currently on my page:
<script src="text/javascript">
function playVideo(){
var video = document.getElementById('addiction-video');
video.play();
video.addEventListener('ended',function(){
location.href = 'http://mywordpresssite.com/addiction-a-call-for-connection-acim/';
});
}
</script>
<video id="addiction-video" autoplay="autoplay" controls="controls" width="600" height="300">
<source src="http://mywordpresssite.com/wp-content/uploads/2015/12/Addictions.mp4" type="video/mp4" />
</video>
Can anyone tell why it's not redirecting after the video has finished playing?
I have the above code directly in my WordPress page; I've tried placing the script below the html, and I've tried adding the script into my theme settings, but neither made it work.
Thank you!
Firstly change <script src="text/javascript"> to <script type="text/javascript"> since you are not importing an external script file. Read a bit about <script> tag.
Secondly you don't need the playVideo() function. Rewrite your code accordingly:
<script type="text/javascript">
var video = document.getElementById('addiction-video');
video.addEventListener('ended',function(){
location.href = 'http://mywordpresssite.com/addiction-a-call-for-connection-acim/';
});
</script>
<video id="addiction-video" autoplay="autoplay" controls="controls" width="600" height="300">
<source src="http://mywordpresssite.com/wp-content/uploads/2015/12/Addictions.mp4" type="video/mp4" />
</video>
You don't need video.play();, since you have autoplay="autoplay" attribute in <video> tag. Read about it here and try it yourself here.
Thirdly keep your browser console open while writing a js code.
Good Luck!
while my question may be similar to the one found at: hide video container when there's no video in database to be displayed HTML PHP, I am looking for a Javascript/jQuery solution.
Essentially the effect I need to achieve is that when the html5 <video> tag can't load the video from its src, I want the div the video tag is contained in to be hidden, preferably with a jQuery solution to this unless there's a very simple way to do this which I have over looked.
What i have so far looks similar to this:
<div id="video">
<video controls="controls" width="320" height="240">
<source src="published/video.mp4" type="video/mp4" />
</video>
</div>
Any input is greatly appreciated.
Here is a pure js solution:
document._video = document.getElementById("video");
document._video.addEventListener('error',function(){
$(document._video).hide()
});
Also you can look at the link below for other video events:
http://www.w3.org/2010/05/video/mediaevents.html
You can detect <video> support with http://modernizr.com/
if (!Modernizr.video) $('#video').hide();

For check if file exists on server - How do I check if file exists in jQuery or JavaScript?

I'm using the Video.js player to stream live content from my local webcam (but I guess that should not matter in that case, it could be any live stream from web). I wrote a really simple code:
<head>
<link href="video-js.css" rel="stylesheet">
<script src="http://www.andy-howard.com/js/libs/jquery-1.8.2.min.js"></script>
<script src="http://vjs.zencdn.net/c/video.js"></script>
<link href="http://vjs.zencdn.net/c/video-js.css" rel="stylesheet">
</style>
</head>
<body>
<video id="video1" class="video-js vjs-default-skin" width="640" height="480" controls="controls"
preload="auto" data-setup='{}' autoplay="true" >
<source src="http://10.172.180.31:8090/live.flv" type="video/x-flv">
</video>
</body>
And now in that configuration I see the stream content, but there are couple errors:
1) I don't see the controls (to pause the stream)
2) Stream looks like this, so the video is not resized to the full size of the component. BUT (and that's really interesting) when I resize the elements on the webpage (e.g. in Chrome by holding control and scrolling the mouse wheel) to 110%, then the video fills the whole component. Seems like a bug in video.js or maybe my implementation is wrong?
3) when I remove the parameter autoplay="true" - nothing shows up, controls and video is gone and it's impossible to play it.
4) I wanted to remove the autoplay="true", but adding the poster info by including poster="http://upload.wikimedia.org/wikipedia/commons/thumb/4/41/NYC_Times_Square_wide_angle.jpg/640px-NYC_Times_Square_wide_angle.jpg" - nothing has changed, the stream is not visible, the controls are not there.
5) when I remove the data-setup parameter and leave it like this:
<video id="video1" class="video-js vjs-default-skin" width="640" height="480" controls="controls"
preload="auto" poster="http://upload.wikimedia.org/wikipedia/commons/thumb/4/41/NYC_Times_Square_wide_angle.jpg/640px-NYC_Times_Square_wide_angle.jpg" > then the controls and poster are visible (which is great!), but the play button is greyed out and it's impossible to play my stream.
I want to achieve the effect that after loading the webpage I can see the poster image with play button, and when I click it - I will see the properly resized stream. What am I missing?
Thanks!
Try it without the controls
This works for me:
<video id="se_videojs" class="video-js vjs-default-skin vjs-big-play-centered" controls preload="auto" height="auto" width="auto" data-setup="{}">
<source src="http://server/playlist.m3u8" type="application/x-mpegurl">
</video>
First of all, try to use the lastest release of video.js, you are using 3.2 version...
<link href="http://vjs.zencdn.net/4.12.6/video-js.css" rel="stylesheet">
<script src="http://vjs.zencdn.net/4.12.6/video.js"></script>
Secondly, if you are trying to use a live (stream) with videojs, you should see how videojs reads the stream sources: https://github.com/videojs/video.js/blob/master/docs/guides/tech.md#enabling-streaming-playback
Note that streaming urls need to have a specific pattern:
{protocol}://{your.streaming.provider.net/cfx/st}/{format}:{videoURL}.{format}
FLV is a video container, not a protocol, you should use a stream protocol such a RTMP(Flash), HDS(Flash), Mpeg/Dash or HLS(Apple).
Regards,
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:
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

.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();

<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">

<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?
Have you tried doing it via JW Player's JavaScript API? From what I gather you can load a playlist and invoke a function that will play a video at a certain index:
playlistItem(index)
Start playback of the playlist item at the specified index.
