So I saw this video player in a course I purchased. Basically the video files are encrypted and have .dsr format and they can only be played by this video player which is accessible only through a key provided by them.
I am really interested in this software, as to how is this implemented and where can I learn to make a prototype of this kind of software.
Basically there are encrypted video files and a video player and it plays these files if it has an access to the key.
I did search for the process of making one’s own codec but it does not seem like they made their own codec maybe what I think it does is it reads the data of video file and removes the unuseful information filled in to make it impossible for a normal player to read.
