Hiding source in flash player

I have to develop an application to play video online using flash player. All the video files have some cost to play/download and should not to be downlo开发者_如何学Goaded.

So now the problem is that when a user play a video he/she can view the source of flash player and then can download.

Please tell me how it is possible to hide or some other stuffs?

How can the user view the source of the Flash video if you use a front end video player? You typically have a video file, then an Flash player application that can browse videos and play them but not reveal the source.

Alternative, is a using a streaming server, like Flash media server, where the video is fed to the front end and not available as a single file.
