Hello I develop an application in AIR / Flash, which allows searching for video on youtube but I have a problem when displaying the swf from youtube an error is reported: [SWF] / v/7UB1NcZirTE - 1811 bytes after decompression [SWF] / yt/swf/cps-vfl129881.swf - 526,778 bytes after decompression *** Security Sandbox Violation *** SecurityDomain 'http://s.ytimg.com/yt/swf/cps-vfl129881.swf' tried to access incompatible context 'http://www.youtube.com/v/7UB1NcZirTE?f=videos&app=youtube_gdata' I add: Security.loadPolicyFile ( "http://i4.ytimg.com/crossdomain.xml"); Security.loadPolicyFile ( "http://www.youtube.com/crossdomain.xml "); But that still does not work and after much research I have yet to find a solution so I ask your help. Thank you.
