That would have to be a part of the Flash Action Script of the video before it was compiled, which can also provide hooks for javascript for this and other purposes, but it would have to be a part of the Flash video before it was compiled, or perhaps done as I outline below. Videos (the part shot with a camera or otherwise encoded into an flv or other raw video format), as far as I know cannot, in themselves, have links.
But I'm no expert on the various video formats, so there may be some other ways I don't know about. In any case, if it really is a link, it will be subject to the base target of the page. So, you could try that:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<base target="vidlink">
</head>
<body>
<iframe name="vidlink" width=425 height=350 src="about:blank"></iframe><br>
<object . . . video code here >
<param . . . >
<embed . . . >
</object>
</body>
</html>
Other links on the page would need to be targeted to _self if you wanted them to act 'normally':
Code:
<a href="some.htm" target="_self">Normal link</a>
