I am trying to reanimate project made ten years ago. SMIL2 was successfully used in IE6.
I have found that IE8 still supports SMIL, however nor t:media, nor t:audio elements do not play audio/media content any more.
Here is simple example that works OK in IE6 (under VirtualPC) but has issues in IE8
<html xmlns:t="urn:schemas-microsoft-com:time">
<head>
<?import namespace="t" implementation="#default#time2">
</head>
<body>
<t:audio src="LoopyMusic.wav" repeatCount="indefinite" type="wav" />
</body>
</html>
Another notice - in case if t:audio is included into sequence (t:seq) - element after t:audio never starts it's effects.
Are there any known issues/workarounds with SMIL support under internet explorer 8?
Use a closing tag instead of an empty tag and add the
timecontainerattribute, since IE8 enforces stricter syntax:References
