Opera browser version 12.17 . Does this version support MP4 h.264 video playback ? Works in FF, IE and chrome , but does not work in Opera.
<div class="row">
<video id="video" width="50%" height="50%" preload="none" controls autoplay>
<source src="{{videosrc}}" type="video/mp4" />
</video>
</div>
.. server side
$scope.videosrc = $sce.trustAsResourceUrl(episode.geturl());
Opera 12 doesn't support h.264 video natively, so you'll need to fallback to using plugins, e.g flash.
Opera 25 and up supports h.264 if supported by the OS (Note: for linux users - you may need to build ffmpeg if the system libs aren't compatible, see these instructions).
