Question

I have developed an application where the user can set videos on a web page: - They can specify a Youtube URL OR - They can upload a video

Depending on which option

Answer 1

[upgraded to answer per request]

Autoplay on most mobile platforms (Android, iOS) gets blocked to avoid poor user experiences - video should only play following a user action. You can usually work around it by triggering the play() on another event (eg the onloaded event)

Answer 2

Auto-play is disabled since Android SDK 17, but you can set setMediaPlaybackRequiresUserGesture to false to re-enable auto-play. Don't forget to check the SDK version because there is not such function in earlier versions.

    int SDK_INT = android.os.Build.VERSION.SDK_INT;
    if (SDK_INT > 16) {
        engine.getSettings().setMediaPlaybackRequiresUserGesture(false);
    }

Answer 3

For Android 4.0.x, try triggering the event : loadstart

var vid=document.getElementById('video');
vid.addEventListener("loadstart", showVideo, false);
function showVideo(e) {
  vid.play();
}

Answer 4

That can not be achieved, autoplay on most mobile platforms (Android, iOS) gets blocked to avoid poor user experiences. Look at this: http://www.longtailvideo.com/html5/autoloop/
