XML VIDEO SPECFIC SITE MAP FOR GOOGLE

I am working on setting up a video site map in xml format for google and I fould this example online (Code Attached). I think I understand most of what I am looking at but I do have a question about line 7 the code references

##<video:player_loc allow_embed="yes" autoplay="ap=1">http://www.site.com/videoplayer.swf?video=123</video:player_loc>##

Full Code and Tag Definitions
http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=80472#2

In this code after http://www.site.com/videoplayer.swf it is making a reference to a file but Im not sure what it means.
I am thinking that after the question mark would be "Directory""File.flv"
Example:
<video:player_loc allow_embed="yes" autoplay="ap=1">http://www.buyandsellcemeteryplots.com/video-player-test-1/player.swf?www.buyandsellcemeteryplots.com/video-player-test-1/=MRSS-10.flv</video:player_loc>##
Can some one please point me in the right direction?
