I have used this code for many flash movie applications but it took me a while to figure out how to make it work with Google Videos. I'm presuming others have also had a hard time figuring it out and so am providing the info here.
You will need to download the "swfobject.js" file from this website - http://blog.deconcept.com/swfobject/
- unzip it and upload the "swfobject.js" file to your web server. The block of code below can be copy and pasted into your webpage with just 2 changes that need to be made. Firstly src="swfobject.js" in the first line needs to point to where the swfobject.js file is located on your server. Secondly the variable fo.addVariable("docId", "4472646496213461848"); needs to be changed to the ID of your Google video. It is a large number similar to the one shown between the quotatin marks and is part of the URL that Google supplies you for viewing or embedding your video.
<div id="swfplayer">Flash Plugin is Required</div>
var fo = new SWFObject(
Pasting it as is into a simple webpage will provide this:http://moodsmusic.org/swfss.html
The above block of code can easily be adapted to suit other swf file embedding as I have done here on my www.robertwatcher.com
(this is using a more complex XML based Flashplayer to produce the flash slideshow - not Google vids)
