I'm trying to build a video player that works everywhere. so far I'd be going with:
<video>
<source src="video.mp4"></source>
<source src="video.ogv"></source>
<object data="flowplayer.swf" type="application/x-shockwave-flash">
<param name="movie" value="flowplayer.swf" />
<param name="flashvars" value='config={"clip":"video.mp4"}' />
</object>
</video>
(as seen on several sites, for example video for everybody)
so far, so good.
But now I also want some kind of playlist/menu along with the video player, from which I can select other videos. Those should be opened within my player right away. So I will have to "dynamically change the source of the video" (as seen on dev.opera.com/articles/everything-you-need-to-know-html5-video-audio/ - section "Let's look at another movie") with Javascript. Let's forget about the Flash player (and thus IE) part for the time being, I will try to deal with that later.
So my JS to change the <source> tags should be something like:
<script>
function loadAnotherVideo() {
var video = document.getElementsByTagName('video')[0];
var sources = video.getElementsByTagName('source');
sources[0].src = 'video2.mp4';
sources[1].src = 'video2.ogv';
video.load();
}
</script>
The problem is, this doesn't work in all browsers. Namely, in Firefox there is a nice page where you can observe the problem I'm having: http://www.w3.org/2010/05/video/mediaevents.html
As soon as I trigger the load() method (in Firefox, mind you), the video player dies.
Now I have found out that when I don't use multiple <source> tags, but instead just one src attribute within the <video> tag, the whole thing does work in Firefox.
So my plan is to just use that src attribute and determine the appropriate file using the canPlayType() function.
Am I doing it wrong somehow or complicating things?
I hated all these answers because they were too short or relied on other frameworks.
Here is "one" vanilla JS way of doing this, working in Chrome, please test in other browsers:
var video = document.getElementById('video');
var source = document.createElement('source');
source.setAttribute('src', 'http://techslides.com/demos/sample-videos/small.mp4');
source.setAttribute('type', 'video/mp4');
video.appendChild(source);
video.play();
console.log({
src: source.getAttribute('src'),
type: source.getAttribute('type'),
});
setTimeout(function() {
video.pause();
source.setAttribute('src', 'http://techslides.com/demos/sample-videos/small.webm');
source.setAttribute('type', 'video/webm');
video.load();
video.play();
console.log({
src: source.getAttribute('src'),
type: source.getAttribute('type'),
});
}, 3000);
<video id="video" width="320" height="240"></video>

Modernizr worked like a charm for me.
What I did is that I didn't use <source>. Somehow this screwed things up, since the video only worked the first time load() was called. Instead I used the source attribute inside the video tag -> <video src="blabla.webm" /> and used Modernizr to determine what format the browser supported.
<script>
var v = new Array();
v[0] = [
"videos/video1.webmvp8.webm",
"videos/video1.theora.ogv",
"videos/video1.mp4video.mp4"
];
v[1] = [
"videos/video2.webmvp8.webm",
"videos/video2.theora.ogv",
"videos/video2.mp4video.mp4"
];
v[2] = [
"videos/video3.webmvp8.webm",
"videos/video3.theora.ogv",
"videos/video3.mp4video.mp4"
];
function changeVid(n){
var video = document.getElementById('video');
if(Modernizr.video && Modernizr.video.webm) {
video.setAttribute("src", v[n][0]);
} else if(Modernizr.video && Modernizr.video.ogg) {
video.setAttribute("src", v[n][1]);
} else if(Modernizr.video && Modernizr.video.h264) {
video.setAttribute("src", v[n][2]);
}
video.load();
}
</script>
Hopefully this will help you :)
If you don't want to use Modernizr , you can always use CanPlayType().
Your original plan sounds fine to me. You'll probably find more browser quirks dealing with dynamically managing the <source> elements, as indicated here by the W3 spec note:
Dynamically modifying a source element and its attribute when the element is already inserted in a video or audio element will have no effect. To change what is playing, just use the src attribute on the media element directly, possibly making use of the canPlayType() method to pick from amongst available resources. Generally, manipulating source elements manually after the document has been parsed is an unncessarily[sic] complicated approach.
http://dev.w3.org/html5/spec/Overview.html#the-source-element
I solved this with this simple method
function changeSource(url) {
var video = document.getElementById('video');
video.src = url;
video.play();
}
Instead of getting the same video player to load new files, why not erase the entire <video> element and recreate it. Most browsers will automatically load it if the src's are correct.
Example (using Prototype):
var vid = new Element('video', { 'autoplay': 'autoplay', 'controls': 'controls' });
var src = new Element('source', { 'src': 'video.ogg', 'type': 'video/ogg' });
vid.update(src);
src.insert({ before: new Element('source', { 'src': 'video.mp4', 'type': 'video/mp4' }) });
$('container_div').update(vid);
According to the spec
Dynamically modifying a source element and its attribute when the
element is already inserted in a video or audio element will have no
effect. To change what is playing, just use the src attribute on the
media element directly, possibly making use of the canPlayType()
method to pick from amongst available resources. Generally,
manipulating source elements manually after the document has been
parsed is an unncessarily complicated approach.
So what you are trying to do is apparently not supposed to work.
Just put a div and update the content...
<script>
function setvideo(src) {
document.getElementById('div_video').innerHTML = '<video autoplay controls id="video_ctrl" style="height: 100px; width: 100px;"><source src="'+src+'" type="video/mp4"></video>';
document.getElementById('video_ctrl').play();
}
</script>
<button onClick="setvideo('video1.mp4');">Video1</button>
<div id="div_video"> </div>
Yaur: Although what you have copied and pasted is good advice, this does not mean that it is impossible to change the source element of an HTML5 video element elegantly, even in IE9 (or IE8 for that matter).(This solution does NOT involve replacing the entire video element, as it is bad coding practice).
A complete solution to changing/switching videos in HTML5 video tags via javascript can be found here and is tested in all HTML5 browser (Firefox, Chrome, Safari, IE9, etc).
If this helps, or if you're having trouble, please let me know.
This is my solution:
<video id="playVideo" width="680" height="400" controls="controls">
<source id="sourceVideo" src="{{video.videoHigh}}" type="video/mp4">
</video>
<br />
<button class="btn btn-warning" id="{{video.videoHigh}}" onclick="changeSource(this)">HD</button>
<button class="btn btn-warning" id="{{video.videoLow}}" onclick="changeSource(this)">Regular</button>
<script type="text/javascript">
var getVideo = document.getElementById("playVideo");
var getSource = document.getElementById("sourceVideo");
function changeSource(vid) {
var geturl = vid.id;
getSource .setAttribute("src", geturl);
getVideo .load()
getVideo .play();
getVideo .volume = 0.5;
}
</script>
I have a similar web app and am not facing that sort of problem at all. What i do is something like this:
var sources = new Array();
sources[0] = /path/to/file.mp4
sources[1] = /path/to/another/file.ogg
etc..
then when i want to change the sources i have a function that does something like this:
this.loadTrack = function(track){
var mediaSource = document.getElementsByTagName('source')[0];
mediaSource.src = sources[track];
var player = document.getElementsByTagName('video')[0];
player.load();
}
I do this so that the user can make their way through a playlist, but you could check for userAgent and then load the appropriate file that way. I tried using multiple source tags like everyone on the internet suggested, but i found it much cleaner, and much more reliable to manipulate the src attribute of a single source tag. The code above was written from memory, so i may have glossed over some of hte details, but the general idea is to dynamically change the src attribute of the source tag using javascript, when appropriate.
Another way you can do in Jquery.
HTML
<video id="videoclip" controls="controls" poster="" title="Video title">
<source id="mp4video" src="video/bigbunny.mp4" type="video/mp4" />
</video>
<div class="list-item">
<ul>
<li class="item" data-video = "video/bigbunny.mp4">Big Bunny.</li>
</ul>
</div>
Jquery
$(".list-item").find(".item").on("click", function() {
let videoData = $(this).data("video");
let videoSource = $("#videoclip").find("#mp4video");
videoSource.attr("src", videoData);
let autoplayVideo = $("#videoclip").get(0);
autoplayVideo.load();
autoplayVideo.play();
});
I come with this to change video source dynamically. "canplay" event sometime doesn't fire in Firefox so i have added "loadedmetadata". Also i pause previous video if there is one...
var loadVideo = function(movieUrl) {
console.log('loadVideo()');
$videoLoading.show();
var isReady = function (event) {
console.log('video.isReady(event)', event.type);
video.removeEventListener('canplay', isReady);
video.removeEventListener('loadedmetadata', isReady);
$videoLoading.hide();
video.currentTime = 0;
video.play();
},
whenPaused = function() {
console.log('video.whenPaused()');
video.removeEventListener('pause', whenPaused);
video.addEventListener('canplay', isReady, false);
video.addEventListener('loadedmetadata', isReady, false); // Sometimes Firefox don't trigger "canplay" event...
video.src = movieUrl; // Change actual source
};
if (video.src && !video.paused) {
video.addEventListener('pause', whenPaused, false);
video.pause();
}
else whenPaused();
};
Using the <source /> tags proved difficult for me in Chrome 14.0.835.202 specifically, although it worked fine for me in FireFox. (This could be my lack of knowledge, but I thought an alternate solution might be useful anyway.) So, I ended up just using a <video /> tag and setting the src attribute right on the video tag itself. The canPlayVideo('<mime type>') function was used to determine whether or not the specific browser could play the input video. The following works in FireFox and Chrome.
Incidently, both FireFox and Chrome are playing the "ogg" format, although Chrome recommends "webm". I put the check for browser support of "ogg" first only because other posts have mentioned that FireFox prefers the ogg source first (i.e. <source src="..." type="video/ogg"/> ). But, I haven't tested (and highly doubt) whether or not it the order in the code makes any difference at all when setting the "src" on the video tag.
HTML
<body onload="setupVideo();">
<video id="media" controls="true" preload="auto" src="">
</video>
</body>
JavaScript
function setupVideo() {
// You will probably get your video name differently
var videoName = "http://video-js.zencoder.com/oceans-clip.mp4";
// Get all of the uri's we support
var indexOfExtension = videoName.lastIndexOf(".");
//window.alert("found index of extension " + indexOfExtension);
var extension = videoName.substr(indexOfExtension, videoName.length - indexOfExtension);
//window.alert("extension is " + extension);
var ogguri = encodeURI(videoName.replace(extension, ".ogv"));
var webmuri = encodeURI(videoName.replace(extension, ".webm"));
var mp4uri = encodeURI(videoName.replace(extension, ".mp4"));
//window.alert(" URI is " + webmuri);
// Get the video element
var v = document.getElementById("media");
window.alert(" media is " + v);
// Test for support
if (v.canPlayType("video/ogg")) {
v.setAttribute("src", ogguri);
//window.alert("can play ogg");
}
else if (v.canPlayType("video/webm")) {
v.setAttribute("src", webmuri);
//window.alert("can play webm");
}
else if (v.canPlayType("video/mp4")) {
v.setAttribute("src", mp4uri);
//window.alert("can play mp4");
}
else {
window.alert("Can't play anything");
}
v.load();
v.play();
}
I have been researching this for quite a while and I am trying to do the same thing, so hopefully this will help someone else. I have been using crossbrowsertesting.com and literally testing this in almost every browser known to man. The solution I've got currently works in Opera, Chrome, Firefox 3.5+, IE8+, iPhone 3GS, iPhone 4, iPhone 4s, iPhone 5, iPhone 5s, iPad 1+, Android 2.3+, Windows Phone 8.
Dynamically Changing Sources
Dynamically changing the video is very difficult, and if you want a Flash fallback you will have to remove the video from the DOM/page and re-add it so that Flash will update because Flash will not recognize dynamic updates to Flash vars. If you're going to use JavaScript to change it dynamically, I would completely remove all <source> elements and just use canPlayType to set the src in JavaScript and break or return after the first supported video type and don't forget to dynamically update the flash var mp4. Also, some browsers won't register that you changed the source unless you call video.load(). I believe the issue with .load() you were experiencing can be fixed by first calling video.pause(). Removing and adding video elements can slow down the browser because it continues buffering the removed video, but there's a workaround.
Cross-browser Support
As far as the actual cross-browser portion, I arrived at Video For Everybody as well. I already tried the MediaelementJS Wordpress plugin, which turned out to cause a lot more issues than it resolved. I suspect the issues were due to the Wordpress plug-in and not the actually library. I'm trying to find something that works without JavaScript, if possible. So far, what I've come up with is this plain HTML:
<video width="300" height="150" controls="controls" poster="http://sandbox.thewikies.com/vfe-generator/images/big-buck-bunny_poster.jpg" class="responsive">
<source src="http://clips.vorwaerts-gmbh.de/big_buck_bunny.ogv" type="video/ogg" />
<source src="http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4" type="video/mp4" />
<source src="http://clips.vorwaerts-gmbh.de/big_buck_bunny.webm" type="video/webm" />
<source src="http://alex-watson.net/wp-content/uploads/2014/07/big_buck_bunny.iphone.mp4" type="video/mp4" />
<source src="http://alex-watson.net/wp-content/uploads/2014/07/big_buck_bunny.iphone3g.mp4" type="video/mp4" />
<object type="application/x-shockwave-flash" data="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf" width="561" height="297">
<param name="movie" value="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf" />
<param name="allowFullScreen" value="true" />
<param name="wmode" value="transparent" />
<param name="flashVars" value="config={'playlist':['http://sandbox.thewikies.com/vfe-generator/images/big-buck-bunny_poster.jpg',{'url':'http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4','autoPlay':false}]}" />
<img alt="No Video" src="http://sandbox.thewikies.com/vfe-generator/images/big-buck-bunny_poster.jpg" width="561" height="297" title="No video playback capabilities, please download the video below" />
</object>
<strong>Download video:</strong> MP4 format | Ogg format | WebM format
</video>
Important notes:
Ended up putting the ogg as the first <source> because Mac OS Firefox quits trying to play the video if it encounters an MP4 as the first <source>.
The correct MIME types are important .ogv files should be video/ogg, not video/ogv
If you have HD video, the best transcoder I've found for HD quality OGG files is Firefogg
The .iphone.mp4 file is for iPhone 4+ which will only play videos that are MPEG-4 with H.264 Baseline 3 Video and AAC audio. The best transcoder I found for that format is Handbrake, using the iPhone & iPod Touch preset will work on iPhone 4+, but to get iPhone 3GS to work you need to use the iPod preset which has much lower resolution which I added as video.iphone3g.mp4.
In the future we will be able to use a media attribute on the <source> elements to target mobile devices with media queries, but right now the older Apple and Android devices don't support it well enough.
Edit:
I'm still using Video For Everybody but now I've transitioned to using FlowPlayer, to control the Flash fallback, which has an awesome JavaScript API that can be used to control it.
Try moving the OGG source to the top. I've noticed Firefox sometimes gets confused and stops the player when the one it wants to play, OGG, isn't first.
Worth a try.
You shouldn't try to change the src attribute of a source element, according to this spec note .
Dynamically modifying a source element and its attribute when the element is
already inserted in a video or audio element will have no effect. To
change what is playing, just use the src attribute on the media
element directly
So lets say you have:
<audio>
<source src='./first-src'/>
</audio>
To modify the src:
<audio src='./second-src'/>
<source src='./first-src'/>
</audio>
if you already have a loaded video and you try to upload a new one over that one make sure to use the videoRef.load() on the second one, otherwise it wont load.
*videoRef should be the ref of the displayed <video></video> tag
Using JavaScript and jQuery:
<script src="js/jquery.js"></script>
...
<video id="vid" width="1280" height="720" src="v/myvideo01.mp4" controls autoplay></video>
...
function chVid(vid) {
$("#vid").attr("src",vid);
}
...
<div onclick="chVid('v/myvideo02.mp4')">See my video #2!</div>
I ended up making the accepted ansower into a function and improving the resume to keep the time. TLDR
/**
* https://stackoverflow.com/a/18454389/4530300
* This inspired a little function to replace a video source and play the video.
* #param video

*/
function swapSource(video, source, src, type) {
let dur = video.duration;
let t = video.currentTime;
// var video = document.getElementById('video');
// var source = document.createElement('source');
video.pause();
source.setAttribute('src', src);
source.setAttribute('type', type);
video.load();
video.currentTime = t;
// video.appendChild(source);
video.play();
console.log("Updated Sorce: ", {
src: source.getAttribute('src'),
type: source.getAttribute('type'),
});
}
Below is my code in aspx page to allow playing audio's of wav format in the browser but with my current code I am unable to play wav audios in Chrome browser but it works in Firefox. How can I handle this exception?
<script>
window.onload = function () { document.getElementById("audio").play(); }
window.addEventListener("load", function () { document.getElementById("audio").play(); });
</script>
<body>
<audio id='audio' controls autoplay>
<source src="Sounds/DPM317.wav" type="audio/wav" />
Your browser does not support the audio element.
</audio>
</body>
For Chrome they changed autoplay policy, so you can read about here:
var promise = document.querySelector('audio').play();
if (promise !== undefined) {
promise.then(_ => {
// Autoplay started!
}).catch(error => {
// Autoplay was prevented.
// Show a "Play" button so that user can start playback.
});
}
Try using a callback like this with the catch block.
document.getElementById("audio").play().catch(function() {
// do something
});
I don't know if this is still actual for you, but I still leave my comment so maybe it will help somebody else.
I had same issue, and the solution proposed by #dighan on bountysource.com/issues/
solved it for me.
So here is the code that solved my problem:
var media = document.getElementById("YourVideo");
const playPromise = media.play();
if (playPromise !== null){
playPromise.catch(() => { media.play(); })
}
It still throws an error into console, but at least the video is playing :)
All new browser support video to be auto-played with being muted only
so please put
<video autoplay muted="muted" loop id="myVideo">
<source src="https://w.r.glob.net/Coastline-3581.mp4" type="video/mp4">
</video>
Something like this
URL of video should match the SSL status if your site is running with https then video URL should also in https and same for HTTP
adding muted="muted" property to HTML5 tag solved my issue
I am using Chrome version 75.
add the muted property to video tag
<video id="myvid" muted>
then play it using javascript and set muted to false
var myvideo = document.getElementById("myvid");
myvideo.play();
myvideo.muted = false;
edit: need user interaction (at least click anywhere in the page to work)
I second Shobhit Verma, and I have a little note to add : in his post he told that in Chrome (Opera for myself) the players need to be muted in order for the autoplay to succeed... And ironically, if you elevate the volume after load, it will still play...
It's like all those anti-pop-ups mechanic that ignore invisible frame slid into your code...
php-echoed html and javascript is :
10-second setTimeout onLoad of body tag that rises volume to maximum, video with autoplay and muted='muted' (yeah that $muted_code part is = "muted='muted")
echo "<body style='margin-bottom:0pt; margin-top:0pt; margin-left:0pt; margin-right:0pt' onLoad=\"setTimeout(function() {var vid = document.getElementById('hourglass_video'); vid.volume = 1.0;},10000);\">";
echo "<div id='hourglass_container' width='100%' height='100%' align='center' style='text-align:right; vertical-align:bottom'>";
echo "<video autoplay {$muted_code}title=\"!!! Pausing this video will immediately end your turn!!!\" oncontextmenu=\"dont_stop_hourglass(event);\" onPause=\"{$action}\" id='hourglass_video' frameborder='0' style='width:95%; margin-top:28%'>";
In my case I had to wait for a user interaction, so I set a click or touchend listener.
const isMobile = navigator.maxTouchPoints || "ontouchstart" in document.documentElement;
function play(){
audioEl.play()
}
document.body.addEventListener(isMobile ? "touchend" : "click", play, { once: true });
Thanks in advance for any help you're able to give. The issue I'm having is that the following code is in a javascript function when a button is clicked. The desired behavior is that on button click, a video fades in, plays for 10 seconds, and fades back out. Then when the button is clicked again, this behavior repeats.
Issue is, the second time the button is clicked, the video fades in but is already at the end of the video and then fades out after 10 seconds. Any idea why the vid.currentTime is not properly resetting the video?
var webm = document.getElementById('src');
webm.src = "src.webm";
var vid = document.getElementById('video');
vid.currentTime = 0;
vid.play();
vid.fadeToggle(1000);
setTimeout(function() {
vid.fadeToggle(1000);
}, 10000);
and this is where the video file is imported
<video id="video" width="100%" Style="Display:none">
<source id="src" src="src.webm" type="video/webm" />
</video>
Additional info has come to light. This only happens in Chrome, and doesn't happen even in Chrome when it's opened locally, only when the html page is served statically via express.
Try
vid.load(); instead of vid.currentTime = 0;
Maybe you can try to add autplay to the video attribute, but I think the video will start looping.
<video id="video" width="100%" Style="Display:none" autoplay>
OR you can add this function or javascript line to your button function.
vid.load();

Figured out that this was only an issue in chrome and seems to have to do with this question:
can't seek html5 video or audio in chrome
I know this question has been asked a number of times, and I've looked through every single one of them here on StackOverflow.
I'm simply trying to loop a 5 second MP4 video in an HTML5 player and have it be seamless. I've tried both jwplayer and video.js, both locally and on webspace, and neither do the trick. I've tried using the "ended" events; I've tried preloading/prebuffering; I've tried listening for the final second of a video and then seeking to the beginning to bypass the stop/play events entirely. I still always see jitter, and I still always see the loading icon (latest Chrome & Firefox).
For reference, here's some of my latest code for video.js:
<video id="loop_me" class="video-js vjs-default-skin vjs-big-play-centered"
width="640" height="480"
data-setup='{"controls": false, "autoplay": true, "loop": true, "preload": "auto"}'>
<source src="video/loop_me.mp4" type="video/mp4" />
</video>
<script type="text/javascript">
var myPlayer = videojs("loop_me");
videojs("loop_me").ready(function(){
this.on("timeupdate", function(){
var whereYouAt = myPlayer.currentTime();
if (whereYouAt > 4) {
myPlayer.currentTime(1);
}
});
});
</script>
Has anyone managed to do this successfully? And, if so, could you please post a complete solution? I don't normally ask for or want those, but I think it might be necessary this time.
Try this:
1) edit your video this way:
[1s][2s][3s][4s][5s]
cut 1st second block of the video and append it 2x to the end like this:
[2s][3s][4s][5s][1s][1s]
2) Use code:
<video id="vid" width="100" height="50" loop autoplay preload="true">
<source src="something.mp4" type="video/mp4">
</video>
<!-- Goes to end of body of course -->
<script>
var vid = document.getElementById("vid");
vid.addEventListener("timeupdate", function () {
if(this.currentTime >= 5.0) {
this.currentTime = 0.0;
}
});
</script>
The idea behind this is to make the video seamless (the end of the video is the beginning of the video). Also, you have to make sure the video never ends. The loop attribute works with smaller video files but you see a black image at the end of the video if too large (before the next looping iteration). Essentially before the video ends, you are seeking back to 0.0s.
I hope that helps.
Heureka!
We've found the actual, real, work-around-free solution to this problem over at where I work. It explains the inconsistent behavior through multiple developers as well.
The tl;dr version is: Bitrates. Who would've guessed? What I suppose is that many people use standard values for this that usually are around 10 Mbit/s for HD videos if you use the Adobe Media Encoder. This is not sufficient.
The correct value would be 18 Mbit/s or maybe even higher. 16 is still a bit janky.
I cannot express how well this works. I've, by now, tried the messiest workarounds for about five hours until I found this together with our video editor.
I hope this helps everyone and saves you tons of time!
Doozerman and Offbeatmammal are correct: no Javascript is required to loop video in HTML5.
About that pause before each iteration: in some browsers we, too, can observe a pause at the end of the loop in our tests. E.g., in the inline, 22-second demo video at...
http://www.externaldesign.com/Marlin-Ouverson.html
...under OS X, we see a ~0.5 sec. pause before the loop repeats -- only in Firefox and Safari; Chrome and Opera both play the loop without noticeable pause. But note: for desktop/laptop browsers, the above page provides an added full-screen background video that appears to loop without pause in all four of the above browsers.
You don't need any extra scripts for that kind of stuff.
The "video" tag has built in loop attribute, use this and your video will loop.
<video id="loop_me" class="video-js vjs-default-skin vjs-big-play-centered" width="640" height="480" controls autoplay loop>
<source src="video/loop_me.mp4" type="video/mp4" />
