Autoplay Video in HTML 5 in Chrome Android 4.1

We have a HTML5 media player that plays video and images from a local drive. The files to play are described in an XML file. In order to not have a pause between videos, the videos are pre-loaded and then play. This has a problem with video: - on Android 4.1 Chrome and webview, the video does not autoplay (requires user to click). - on Firefox, the video autoplays, but crashes after a short period of time (I believe this is a Firefox bug). The job: modify existing HTML5 code so that it retains all existing functionality but successfully autoplays video on either or all of Chrome/webview or Firefox on Android 4.1 , with no pause on video loading. The code must run reliably for at least 24 hours non stop.
