Can you tell me detailed flash player version (e.g. 11.3.300.257), browser and platform information?
Or, please try to play an encrypted content on http://drmtest2.adobe.com/AccessPlayer/player.html
BTW I use RTMP to deliver the video stream
I couldn't see the problem with same version of flash player on Windows XP.
Do you have an another computer that you can use?
I think error 3329 is pretty rare. Are you using any proxy server and/or firewall software?
it works fine on Windows XP
But it does not work on Windows Vista or Windows 7
I couldn't see the problem on Windows 7 32bit and 64bit.
If you think it is latest flash player issue, you can try to use older flash player to see the problem still happens or not.
Archived Flash Players are available at:
So the error reported is actually one that's application specific. Some details around 3329 here
Indication is that the Flash Access server has returned an error for this case. Assuming that you have access to the server, please check its error logs, as likely some more information is available to the nature of the issue.
