HTML embed autoplay="false", but still plays automatically

<video width="320" height="240" controls autoplay>
<source src="movie.mp4" type="video/mp4"> Your browser does not support the video tag.
</video>

Remove autoplay if you want to disable auto playing video.

Chrome doesn't seem to understand true and false. Use autostart="1" and autostart="0" instead.
