Flash flv player has a property that it takes only the flv video files in the same domain.Here the crossdomain policy comes in to picture.
The use of crossdomain.xml policy is very vast, because now a days many websites use .flv [VIDEO FILES] and the webmaster sometimes need flv files to be hosted in other domains.
Without the crossdomain.xml file we cant call a flv video file which is hosted in another domain.The XML file looks like the one shown below just copy and paste the content to a file and rename it to crossdomain.xml, remeber to delete the numbers in the starting of each line.
<?xml version=”1.0″?>
<!DOCTYPE cross-domain-policy SYSTEM “http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd”>
<cross-domain-policy>
<allow-access-from domain=”*” />
</cross-domain-policy>
 Then copy the file and host it to the domain where you are using your flash player.
Now you are done.You can now play any flv file from any domains.
