I am going to make a player for .avi and .wmv files.



How protect .wmv and .avi from playing. I would like to play these files
only with my player.

An idea: you should scrambling the .wmv and .avi files. And your player
should be the only player able to de-scrambling that files..

only with my player.

Why?

(1) Playing with file standard...
Apply some encryption techniques like adding constant bits to all existing
bit and make it unreadable or junks to other players.When you are trying to
open the same, apply revese logic to get the original stream of bits.
(2) Playing with file format
Append any junk file with existing avi or mov, i mean using file binding
techniques and make it as your own file extension say, File1.movv etc.....

hope any of this technique will work..

Problem here is file size. I am trying to use encryption on file, but fistly
needs to be opened and decrypted and played... It takes time because these
files are from 10 to 80 Mb

The reason for this is copy protection.

Thanks
