We are having trouble firing events on Android 2.x devices. From our testing, Android 4.x and iOS 5/6 work correctly. But on Android 2.x devices, we are sometimes getting the "end" event and sometimes we are getting the "start" event.
It says it has cross browser compatibility but anyone run into these issues?
Here are the relevant parts of the code
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="http://vjs.zencdn.net/c/video-js.css">
<script src="http://vjs.zencdn.net/c/video.js"></script>
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
</head>
<body>
<div id="videoplayer" style="margin:0 auto; text-align:center;">
<video id="video" class="video-js vjs-default-skin" controls autoplay preload="auto" width="300" height="300">
</video>
</div>
</body>
</html>
<script>
$(document).ready(function() {
_V_("video").ready(function() {
var thePlayer = this;
var startVideo = function() {
// do stuff
};
var endVideo = function() {
// do stuff
};
thePlayer.addEvent("play", startVideo);
thePlayer.addEvent("ended", endVideo);
});
});
</script>
I figured out the problem. I was able to reproduce it on a Android 2.2 and 2.3 emulator. No events were firing on video playback because there was an error loading the video.
Issues (For Android 2.x devices):
Playing a link from an HTTPS url was no working. The link we were using was an Amazon Cloudwatch URL which linked to an Amazon S3 bucket. When I changed the url to an HTTP vs HTTPS URL it worked.
I had to remove the autoplay attribute on the video element. Not sure why, but the video player in Android 2.x didn't like this.
Once I made these 2 fixes I was able to stream video on Android 2.x devices (as well as Android 4.x, iPhone and iPod)

Background
I have a Chrome Kiosk App where i would like to use the chrome.networking.onc API to let my users change WiFi networks.
My issue
There is no chrome.networking.onc API available to the app neither in the app background script or the app window while running in a kiosk session.
What I've tried
According to the chrome.networking.onc documentation it should be available to apps while in kiosk mode.
I've added networking.onc to my permissions in my app manifest.
https://developer.chrome.com/apps/networking_onc
https://developer.chrome.com/apps/declare_permissions
The kiosk app is force installed to the users Chromebooks using a G Suite Chrome device management policy.
Code example
app/manifest.json
{
"manifest_version": 2,
"name": "Kiosk networking.onc",
"version": "1.0",
"permissions": ["networking.onc"],
"kiosk_enabled": true,
"kiosk_only": true,
"app": {
"background": {
"scripts": ["background.js"]
}
}
}
app/background.js
chrome.app.runtime.onLaunched.addListener(function(launchData) {
// send a list of available chrome APIs to the app window to be displayed
chrome.app.window.create(`window/main.html?chrome=${Object.keys(chrome).join(",")}&kiosk=${launchData.isKioskSession}`);
});

</html>
app/window/main.js
// display the available Chrome APIs in the background script
document.getElementById("background").innerText = window.location.search;
// display all the available Chrome APIs (accessible from the app window).
document.getElementById("window").innerText = Object.keys(chrome).join(",");
document.getElementById("exit").onclick = () => window.close()
Output while in a kiosk session (Chrome OS 77.0.3865.105)
In the image below networking cannot be found among the available APIs and if i try to access networking.onc i get the error: Uncaught TypeError: Cannot read property 'onc' of undefined
This issue seems to be caused by a bug in Chrome OS.
I've reported the issue in the Chromium issue tracker here: https://bugs.chromium.org/p/chromium/issues/detail?id=1012629
I'm trying to follow the GettingStarted instructions on https://github.com/googleads/videojs-ima to setup videojs with ima. But, am getting stuck on the part "In player.js, load the ads library"; nothing has been changed in the local player.js file so it still looks exactly the same as here https://github.com/videojs/video.js/blob/master/src/js/player.js.
Bellow is the current code I have, but when it's ran in IE11, the console reports a warning and two errors:
Warning: "VIDEOJS: WARN: videojs.plugin() is deprecated; use videojs.registerPlugin() instead" in video.js (489,5)
Error: "SCRIPT1002: Syntax error" in player.js (5,1)
Error: "CSS3120: No fonts available for #font-face rule" in video-js.css (12,7)
Any input very much appreciated.
Thank you.

I am trying to play the recorded video from Red5 pro video using the html 5 controls.
I managed to do the live streaming with .m3u8 extension and i can't play the videos already recorded [Video On Demand (VOD)].
I use the video js player for playing live stream ,but the same code is not working for recorded videos.
<video id=red5pro-video width=600 height=300 class="video-js vjs-default-skin" controls></video>

****JS Code : ****
How can i play it or could you provide me some samples if you have?
<script>
(function () {
var player = videojs('red5pro-video');
player.src({
src: "http://54.255.142.187:5080/live/kris.m3u8",
type: "application/x-mpegURL",
useCueTags: true
});
window.onOrientation(player, 'red5pro-video');
player.play();
})();

Having an issue that has been frustrating me the last few days.
I have some videos on a site that are loaded dynamically from sitecore, and display on a page with thumbnail images. When you click those images you are taken to a lightbox with the video.
The problem is, the video plays in Chrome, Firefox and IE8 -, but not IE9 +. I thought it may be an encoding issue, but I have converted this video so many times to every format available to the web to no avail.
I am setting the plugin to load the video as flash first, then if flash isn't available, load as html5. This will clear all worries in terms of browser support of HTML5 video.
I was thinking that it may be the lightbox and videoJS plugin fighting with each other, or the fact that i am hiding videos and showing them, which i know can sometimes cause issues. I have decided to use a different lightbox, and people seem to have said that colorbox is a decent one to use with videoJS, especially since it has some built in callbacks onLoad.
On to the problem and the code:
The problem:
This lightbox is working, but videoJS seems to throw a few errors when i try and reset the player, which is breaking the videos in IE since its such a dumb browser.
As you can see in the demo link at the bottom, the videos play in IE just fine when they are just set on the page, but when you open the lightbox by pressing "vid1" or "vid2" you are riddled with console errors and the videos no longer play.
The code:

Console errors im getting:
Uncaught TypeError: Object #<HTMLObjectElement> has no method 'vjs_getProperty'
LIVE DEMO:
Go here to see the errors for yourself: http://kodistro.com
In this case, my solution is to inject the video tag HTML into the lightbox content (when opening) and then call videojs().
So, in pseudo-code:
<script type="text/javascript">
$(document).ready(function() {
$(".inline", this).colorbox({
inline: true,
rel: 'videohook',
width: '650px',
height: '274', //the size most be fixed
onLoad: function() {
var appendVideo1 = '<video id="my_video_1"......> </video>'; //insert the <video> tag. Note.Remove attribute data-setup='{"techOrder": ["flash", "html5"]}'
$("video_1").append(appendVideo1);
},
onComplete: function() {
videojs(my_video_1); //initialize video-js
},
onClosed: function() {
videojs(my_video_1).dispose(); //destroy video-js
}
});
});
</script>
<a rel="videohook" data-vidID="my_video_1" class="inline" href="#video_1">vid 1</a>
<div id="video_1" class="video">
</div>
I have an HTML5 page, and it looks like this:
<html>
<head></head>
<body>
<canvas id="c1" width="500" height="500" />
</body>
</html>
I used Bootstrap 3 and Fabric.js as a canvas library. When I run it on mobile device, I have got an issue that when I touch the object on canvas and move it, the page is moved too. Seems the touch event is also handled by mobile device browser.
What I expect is that to stop the default event handle for mobile device browser, so when I touch the object in canvas and move it, the web page will not move as well. How can I make this with Fabric.js?
I have changed the way while I making the html:
<meta name="viewport" content="width=device-width, initial-scale=0.5, user-scalable=no">
And then, to prevent browser default zoom bouncing, we can bind "touchmove" in document and disable it. That's from jQuery mobile, but vmousemove = touchmove for mobile device somehow.
$(document).on("vmousemove", "body", function(e) {
e.stopPropagation();
e.preventDefault();
return false;
});
This is not about Fabric.js anyway, so I don't have to change Fabric.js or else.
