vjs-video
An angular.js directive for video.js
With vjs-video
, you can easily incorporate video and audio into your Angular projects using the robust HTML video player video.js
.
The vjs-video
directive handles all of the complexity involved with using video.js
within an AngularJS Single Page App (SPA) and includes the following features:
- bootstrapping
video.js
after the view is ready - properly disposing the video when the current Angular view is out of scope
- loading and hot swaping videos using Angular data binding
- audio support (for video.js versions >= 4.9)
- responsive container (for video.js 4.x versions)
Dependencies
- video.js (4.x or 5.x)
- angular.js >= 1.3
Installation
The vjs-video
directive avaible via both npm and bower.
Bower
The vjs-video
directive is available via bower with built in dependencies for video.js
and angular
. Be sure to run npm install -g bower
if you don't already have bower installed then run the following to install vjs-video
into your project.
bower install --save vjs-video
If you leverage wiredep in your build workflow, all the required script and stylesheet includes are automatically injected into your html file.
Webpack
Use npm to install vjs-video
. The angular and video.js modules will also be installed as dependencies if they aren't already defined.
npm install --save vjs-video
See here for an example of using
vjs-video
with webpack.
RequireJS
The AMD module loading pattern employed by require.js is supported by vjs-video
but you must shim angular
and define videojs
as a path as seen in the following example.
scripts/main.js
//requirejs configuration
requirejs.config({
baseUrl: 'bower_components',
shim: {
angular: {
exports: 'angular'
}
},
paths: {
angular: 'angular/angular',
videojs: 'video.js/dist/video-js/video',
'vjs-video': '../scripts/directives/vjs.directive'
}
});
//require angular and vjs-video
require(['angular', 'vjs-video'], function (angular) {
angular.module('app', ['vjs.video'])
.controller('MainCtrl', ['$scope', function (scope) {
scope.$on('vjsVideoReady', function(e, data) {
//data contains `id`, `vid`, `player` and `controlBar`
});
}]);
});
Manual Install
Download the latest vjs-video build as well as Angular and video.js. Then, include angular
, video.js
, and vjs-video
as script tags along with it's corresponding css into your HTML page.
<html ng-app="app">
<head>
<link rel="stylesheet" href="bower_components/video.js/dist/video-js/video-js.css" />
</head>
<body ng-app="app">
<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/video.js/dist/video.js"></script>
<script src="bower_components/vjs-video/dist/vjs-video.js"></script>
</body>
</html>
Basic usage
The vjs-video
directive is designed to be non-invasive; to use it, include vjs-video
as a dependency and add the directive to a video or audio tag styled for video.js
.
First include vjs-video
as a dependency within your angular app:
angular.module('app', [ 'vjs.video']);
Next, add the vjs-video
directive to a video or audio tag styled for video.js
:
<video class="video-js vjs-default-skin" controls preload="auto"
width="640" height="264" poster="poster.jpg" vjs-video>
<source src="example_video.mp4" type="video/mp4">
</video>
Responsive Container
The vjs-video-container
directive implements responsive sizing for the 4.x version of video.js
4.x. A custom aspect ratio can be defined with the default being the 16:9 wide screen ratio.
NOTE: The vjs-video-container
is meant to be used with version 4.x of video.js
; video.js
5.x natively supports video. If used with 5.0, the vjs-video-container
aspect ratio values are passed through to video.js
.
The following example wraps a video.js
instance within a responsive container with a ratio of 4:3
:
<vjs-video-container vjs-ratio="4:3">
<video class="video-js vjs-default-skin" controls preload="auto" poster="poster.jpg">
<source src="example_video.mp4" type="video/mp4">
</video>
</vjs-video-container>
When using
vjs-video-container
be sure to attach all the directive attributes (such asvjs-setup
orvjs-media
) to thevjs-video-container
element rather than on the enclosed video or audio tag. The attributes only should be attached when using in conjunction with thevjs-video
directive on a video or audio tag.
Also, make sure you never mix usage of
vjs-video-container
withvjs-video
. Thevjs-video
directive accepts the same directive attributes but shouldn't be used if a video or audio tag is wrapped inside of avjs-video-container
.
Directive Attributes
The vjs-video
directive includes additional attributes that leverage AngularJS's strengths.
- vjs-setup - accepts an object as alternative to using data-setup on the video element
- vjs-media - accepts a bindable object that defines sources and tracks
- vjs-ratio - defines the aspect ratio in the format width:height
NOTE: the
vjs-ratio
attribute support is limited to usage with thevjs-video-container
item when usingvideo.js
< 5.0. In 5.0 and above,vjs-ratio
can be used with thevjs-video
directive as well.
vjs-setup
You can use vjs-setup
instead of the data-setup
attribute video.js
uses if you would prefer to define all of the properties on the scope vs an inline JSON string.
The following example will set the loop option for the video.js
instance using the vjs-setup
attribute:
HTML
<video class="video-js vjs-default-skin" controls preload="auto"
width="640" height="264" vjs-video vjs-setup="options">
<source src="http://video-js.zencoder.com/oceans-clip.mp4" type='video/mp4' />
</video>
JavaScript
angular.module('app')
.controller('MainCtrl', ['$scope', function (scope) {
scope.options = {
loop: true
};
}]);
vjs-media
The vjs-media
option expects a reference to an object that contains a sources
, tracks
, and/or poster
element. Whenever the vjs-media
value is changed, video.js
is reinitialized given the new data.
The following example defines a poster image, two sources and one track in a scope variable that is processed by vjs-video
.
HTML
<video class="video-js vjs-default-skin" controls preload="auto"
width="592" height="252" vjs-video vjs-media="mediaToggle">
</video>
JavaScript
angular.module('app')
.controller('MainCtrl', ['$scope', function (scope) {
scope.mediaToggle = {
sources: [
{
src: 'images/happyfit2.mp4',
type: 'video/mp4'
},
{
src: 'images/happyfit2.webm',
type: 'video/webm'
}
],
tracks: [
{
kind: 'subtitles',
label: 'English subtitles',
src: 'assets/subtitles.vtt',
srclang: 'en',
default: true
}
],
poster: 'images/screen.jpg'
};
//listen for when the vjs-media object changes
scope.$on('vjsVideoMediaChanged', function (e, data) {
console.log('vjsVideoMediaChanged event was fired');
});
}]);
In the event that the
vjs-media
object changes, avjsVideoMediaChanged
event is fired within the scope context as seen in the above example.
vjs-ratio
The vjs-ratio
attribute only works in conjunction with the vjs-video-container
directive when using video.js
4.x but can be used with either the vjs-video
or vjs-video-container
directives when using version 5 of video.js.
The value should list width and then height separated by a :
(w:h)
. The value can be the actual width and height or the least common denominator such as 16:9
.
Getting a reference to the video.js instance
There are times you will want to get access to the video object that video.js
creates. The vjs-video
directive dispatches an event after initialization and can be accessed by listening on the scope for the vjsVideoReady
event.
angular.module('app')
.controller('MainCtrl', ['$scope', function (scope) {
scope.$on('vjsVideoReady', function (e, data) {
//data contains `id`, `vid`, `player` and `controlBar`
//NOTE: vid is depricated, use player instead
console.log('video id:' + data.id);
console.log('video.js player instance:' + data.player);
console.log('video.js controlBar instance:' + data.controlBar);
});
}]);
The second parameter of the callback is a data object which contains the following:
- id: the CSS id value for the video
- player: the video.js player object instance
- vid: the video.js player object instance (deprecated, use
player
instead) - controlBar: the controlBar element of the video.js object
Build & development
