I'm new with AngularJS. I must create customs controls for a video player (HTML5 <video>
).
Basically, I would use getElementById('myvideotag')
, listen clicks on the video for play/pause.
How I can do this with AngularJS ? Binding the click with ng-click="videoPlayPause()"
but then, how I play or pause the video. How I use the classic methods of <video>
?
I guess it's really simple... I didn't get all the AngularJS concepts yet !
Thank you :)
Oh, the code... in the view:
<video autoplay="autoplay" preload="auto" ng-click="video()">
<source src="{{ current.url }}" type="video/mp4" />
</video>
In the right controller:
$scope.video = function() {
this.pause(); // ???
}
For full control, like behaviour and look&feel, I'm using videoJS
in angular.
I have a ui-video
directive that wraps the video
HTML5 element. This is necessary to overcome a problem of integration with AngularJS:
m.directive('uiVideo', function () {
var vp; // video player object to overcome one of the angularjs issues in #1352 (https://github.com/angular/angular.js/issues/1352). when the videojs player is removed from the dom, the player object is not destroyed and can't be reused.
var videoId = Math.floor((Math.random() * 1000) + 100); // in random we trust. you can use a hash of the video uri
return {
template: '<div class="video">' +
'<video ng-src="{{ properties.src }}" id="video-' + videoId + '" class="video-js vjs-default-skin" controls preload="auto" >' +
//'<source type="video/mp4"> '+ /* seems not yet supported in angular */
'Your browser does not support the video tag. ' +
'</video></div>',
link: function (scope, element, attrs) {
scope.properties = 'whatever url';
if (vp) vp.dispose();
vp = videojs('video-' + videoId, {width: 640, height: 480 });
}
};
});
How about this:
$scope.video = function(e) {
var videoElements = angular.element(e.srcElement);
videoElements[0].pause();
}
I believe this is the simplest method.

Also, this might help you get used to Angular: How do I “think in AngularJS/EmberJS(or other client MVC framework)” if I have a jQuery background?
You could also take a look to my project Videogular.
https://github.com/2fdevs/videogular
It's a video player written in AngularJS, so you will have all the benefits of bindings and scope variables. Also you could write your own themes and plugins.
I also used videojs
bower install videojs --save
I wanted to use my directive in a ng-repeat
and with a scope object, so... here's my version of it with props to Eduard above. I didn't seem to have a problem with the video player disposal, but the source tag issue referenced was an actual problem.
I also decided to write this up as an answer, so that I could give an example of how one might want to handle the videojs events.
IMPORTANT! Please note I am using Angular.js with Jinja2 templates, so I had to change my Angular HTML interpolation markers to {[ ]}
from {{ }}
in case anyone notices that as weird. I'll include that code too, so it's not weird for anyone.
Interpolation tweak
app.config(['$interpolateProvider', function($interpolateProvider) {
$interpolateProvider.startSymbol('{[');
$interpolateProvider.endSymbol(']}');
}]);
Directive
angular.module('myModule').directive('uiVideo', function () {
// Function for logging videojs events, possibly to server
function playLog(player, videoId, action, logToDb) {
action = action || 'view';
var time = player.currentTime().toFixed(3);
if (logToDb) {
// Implement your own server logging here
}
// Paused
if (player.paused()) {
console.log('playLog: ', action + " at " + time + " " + videoId);
// Playing
} else {
console.log('playLog: ', action + ", while playing at " + time + " " + videoId);
if (action === 'play') {
var wrapFn = function () {
playLog(player, videoId, action, logToDb);
};
setTimeout(wrapFn, 1000);
}
}
}
return {
template: [
'<div class="video">',
'<video id="video-{[ video.id ]}" class="video-js vjs-default-skin img-responsive" controls preload="none"',
' ng-src="{[ video.mp4 ]}"',
' poster="{[ video.jpg ]}"',
' width="240" height="120">',
'</video>',
'</div>'
].join(''),
scope: {
video: '=video',
logToDb: '=logToDb'
},
link: function (scope, element, attrs) {
scope.logToDb = scope.logToDb || false;
var videoEl = element[0].children[0].children[0];
var vp = videojs(videoEl, {},
function(){
this.on("firstplay", function(){
playLog(vp, scope.video.id, 'firstplay', scope.logToDb);
});
this.on("play", function(){
playLog(vp, scope.video.id, 'play', scope.logToDb);
});
this.on("pause", function(){
playLog(vp, scope.video.id, 'pause', scope.logToDb);
});
this.on("seeking", function(){
playLog(vp, scope.video.id, 'seeking', scope.logToDb);
});
this.on("seeked", function(){
playLog(vp, scope.video.id, 'seeked', scope.logToDb);
});
this.on("ended", function(){
playLog(vp, scope.video.id, 'ended', scope.logToDb);
});
}
);
}
};
});
Directive HTML usage
<div ng-repeat="row in videos">
<ui-video video="row"></ui-video>
</div>
