Encrypt/corrupt/something video files
Posted on 2013-01-10
i have a bunch of short .wmv video clips that i've made using camtasia and i'm building a simple vb6 app that will act as the media player to play said clips (using the microsoft media component in vb). my problem is that i dont want anyone to play these video clips using anything besides my vb6 media player app, what are my possible solutions?
off the top of my head i was thinking to encrypt the video clips and then when someone tries to load said clips in my player to copy them to a temp folder, decrypt, play, delete when finished. obviously theres a lot of dead time here in copying and decrypting, as well as obviously the cleanup and 'security' of it. unfortunately i dont know anything about media files and their structure, im guessing encrypting the entire file isnt required as long as one could encrypt/corrupt the file header thus removing the ability for other media players to interpret what codec's are used and whatnot, however i'm sure there are far better solutions out there. what can anyone think of?
