i cant guarantee that these will work due to Symbian having one hell of a bad browser.. but the recent Refresh and Fp1, Fp2 browsers have improved html5 a bit.
video playback
<!DOCTYPE html>
<html>
<body>
<video width="320" height="240" controls="controls" autoplay="autoplay">
<source src="movie.mp4" type="video/mp4" />
<source src="movie.ogg" type="video/ogg" />
<source src="movie.webm" type="video/webm" />
Your browser does not support the video tag.
</video>
</body>
</html>
draw inside Canvas
<!DOCTYPE html>
<html>
<body>
<canvas id="myCanvas" width="200" height="100" style="border:1px solid #c3c3c3;">
Your browser does not support the HTML5 canvas tag.
</canvas>
<script type="text/javascript">
var c=document.getElementById("myCanvas");
var ctx=c.getContext("2d");
ctx.fillStyle="#FF0000";
ctx.fillRect(0,0,150,75);
