Facebook and vshare

i tried ti integrate my vshare videos in facebook
i have a whitelist website and i do the job by specifying meta tags Facebook Share/Specifying Meta Tags - Facebook Developer Wiki

i integrate the video in facebbok by the right thumb
but when playing in facebook, the player appears and said :'video not found '

i think that my error is :
<link rel="video_src" href="http://www.myexample.com/player/player.swf?file=http://www.myexample.com/xml_playlist.php?id='.$video_id.'"/>

plz how to fix it ? by specifying the right video to the player ?
what is the name of the player of vshare ? in order to read documentation
any idea is welcome
