Can anyone familiar with this explain how these programs work? Like what is the process that the program goes through when its fed a .MP3, .JPG, or .AVI file for example?

First, the program reads the file’s header and metadata to figure out what’s inside the file (or whether it’s even capable of reading it), how it’s structured, and where the video and audio data is.

Once it knows that, it knows what pieces of the file to pull out and send to your speakers or your graphics card.
