Can't open downloaded video with PhoneGap - javascript

I download my files with:
var fileTransfer = new FileTransfer();
fileTransfer.download(
url,
target,
..
);
And then i open them later with:
window.open(targetUrl, '_blank', 'location=no');
It works for PDF, XLX, DOCX etc. but not for AVI or MP4.
It opens the Video Player with a Play Button and a 'loading..' Text.
If i try to open the AVI or MP4 directly it plays the files just fine.
What am I doing wrong? Thanks!
Edit: I use a iPad
Edit2: The Error: webView:didFailLoadWithError - 204: Plug-in handled load

Try something like this if you have HTML:
<video width="320" height="240" controls>
<source src="movie.mp4" type="video/mp4">
</video>
Try something like this is you just have Javascript:
function addSourceToVideo(element, src, type) {
var source = document.createElement('source');
source.src = src;
source.type = type;
element.appendChild(source);
}
var video = document.createElement('video');
document.body.appendChild(video);
addSourceToVideo(video, targetUrl, 'video/mp4');
video.play();
Also, ensure that you have the inappbrowser plugin installed.
phonegap plugin add org.apache.cordova.inappbrowser
per: phonegap open link in browser

I found the solution to my question:
Streaming of Videos in the browser is supported and playing local files is not. A native plugin will do the trick

Have video Quality Controls in hls.js / Video.js for Live Streaming

Using HLS.js
(() => {
var video = document.getElementById('video');
console.log('VIDEO',video);
if(Hls.isSupported()) {
var hls = new Hls();
hls.loadSource('https://test-streams.mux.dev/x36xhzz/x36xhzz.m3u8');
hls.attachMedia(video);
hls.on(Hls.Events.MANIFEST_PARSED,function() {
//https://github.com/video-dev/hls.js/blob/master/docs/API.md#quality-switch-control-api
//console.log('RAHUL',hls.levels);
video.play();
});
}
// hls.js is not supported on platforms that do not have Media Source Extensions (MSE) enabled.
// When the browser has built-in HLS support (check using `canPlayType`), we can provide an HLS manifest (i.e. .m3u8 URL) directly to the video element through the `src` property.
// This is using the built-in support of the plain video element, without using hls.js.
// Note: it would be more normal to wait on the 'canplay' event below however on Safari (where you are most likely to find built-in HLS support) the video.src URL must be on the user-driven
// white-list before a 'canplay' event will be emitted; the last video event that can be reliably listened-for when the URL is not on the white-list is 'loadedmetadata'.
else if (video.canPlayType('application/vnd.apple.mpegurl')) {
video.src = 'https://test-streams.mux.dev/x36xhzz/x36xhzz.m3u8';
video.addEventListener('loadedmetadata',function() {
video.play();
});
}
video.addEventListener('canplaythrough', () => {
var promise = video.play();
if (promise !== undefined) {
promise.catch(function(error) {
console.error('Auto-play was prevented');
}).then(function() {
console.info('Auto-play started');
});
}
});
})();
In this Stream i can get the levels or the qualities i have for the Video but the controls dosen't show up in the video player. how can we get that .

Changing html5 video source with preloading

I'm setting up a video portfolio site to showcase different concepts for software devs, and there are often multiple versions of the same video.
I wrote the following javascript to change videos and it works fine locally, the problem is that once its hosted changing videos breaks the video player. I'm guessing the cause is because the new video is not loaded. Any ideas?
function switcher(wrapper, e, source, container, video){
//get current version and turn off its style
var off = document.getElementById(wrapper).getElementsByClassName("versionActive")[0];
off.className = "version";
//turn on the new button
e.className = "versionActive";
var videoSource = document.getElementById(source);
var videoContainer = document.getElementById(container);
lastPlayingVideo.currentTime = 0;
lastPlayingVideo.pause();
lastPlayingVideo = videoContainer;
videoSource.setAttribute('src', video);
videoContainer.load();
videoContainer.play();
}
The html for the video player looks like this:
<video id="container1" controls="" loop="" preload="auto" width="1280" height="720">
<source id="video1" src="videos/Reminder.mp4" type="video/mp4">
</video>
Try :
videoContainer.addEventListener('canplay', function() {
videoContainer.play();
videoContainer.removeEventListener('canplay');
});
videoSource.setAttribute('src', video);
videoContainer.load();
canplay is fired when the browser supposes you have received enough of the file and you can continue playing it considering your connection speed.

Mobile browser cannot play audio from local blob data

I want to play blob data (mp3).
I wrote code like this.
This code successfully doing in PC browser.
But Mobile browser cannot play.
//javascript source
var url = URL.createObjectURL(blob);
audio = document.getElementById("audio");
audio.src = url;
audio.load();
audio.play();
//html source
<audio id="audio" type="audio/mp3">
</audio>
I deleted codes. so I re-post.
startPlaying function will be called by button click action.
var blob;
// blob object has been created other logic.
function startPlaying(button) {
var url = URL.createObjectURL(blob);
audio = document.getElementById("audio");
audio.src = url;
audio.load();
audio.play();
}
For Chrome on Android, this does not seem to be possible - there is currently a bug for it.
(it was closed and marked as fixed, but as you can see from the comments, doesn't work for everyone - including myself).
I needed only a localhost solution. My problem was solved when I enabled in chrome//flags the flag #enabled-unified-media-pipeline on Android.

How to serve the correct format for html5 dynamic video?

I'm trying to find a way to serve the correct video format (I have my videos encoded in h264 and webm ) when the videos are loaded dynamically onto a canvas using the function below:
function loadVideo(video_path){
var ctx = document.getElementById('c').getContext('2d');
var vid = document.getElementById('v');
vid.src = video_path;
vid.load();
// play the video once it has loaded
vid.addEventListener('canplay', function(e){
vid.style.display = "block";
vid.play();
}, false);
// hide the video container once the video has finished playing
vid.addEventListener('ended', function(e){
vid.style.display = "none";
}, false);
}
Here is the simple html inside the body tag:
<video id="v" type="video/webm" width="960" height="500"></video>
<canvas id="c"></canvas>
I could go down the user agent sniffing route to give me the correct video_path string but is there a more elegant way?
Modernizr is a nice way to detect browser features. It also tells you what format the video should have: http://www.modernizr.com/docs/
If video support is detected, Modernizr assesses which formats the current browser will play. Currently, Modernizr tests ogg, webm and h264.

changing source on html5 video tag

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>
External Link
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.mp4" type="video/mp4" />
<source src="http://clips.vorwaerts-gmbh.de/big_buck_bunny.webm" type="video/webm" />

<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>
