HTML5 video error handling

Question

I need to tell, whether video cannot be played (\"x\" sign is shown in browser).

This code does\'t works. \"onerror\" event will never be fired under Firefox

Answer 1

From Firefox 4 onwards, the 'error' event is dispatched on the element.

And you should add an error handler on the only/last source:

HTML

JS

var v = document.querySelector('video#vid');
var sources = v.querySelectorAll('source');

if (sources.length !== 0) {
    var lastSource = sources[sources.length-1];

    lastSource.addEventListener('error', function() {
        alert('uh oh');
    });
}

JQuery

$('video source').last().on('error', function() {
    alert('uh oh');
});

AngularJS

You can create an error handling directive (or just use ng-error):

Where the error handling directive's link function should do (copied from ng-error):

element.on('error', function(event) {
    scope.$apply(function() {
        fn(scope, {$event:event});
    });
});
