Reverse engineering is simpler than it looks like: while it's true that there are so many different kinds of audio and video files, there are lots of ways to read them, and make them work with existing software.
During this talk, we will discuss about the ethics, and the motivation behind reverse engineering, and why it is important. We will also analyze a few video technologies, as introduction, and explain the basic hacking techniques, with some practical cases from the real world.
You will be surprised how most techniques do not require any particular tool, except, perhaps, a brain.
