How are video conversion programs made? Do they seriously understand every single file format of every single type they implement or is it using direct show filters or something? Basically i am interested in making my own but if i actually have to research every single file format to convert then i think ill pass O_O
So whats the go, direct show filters? libraries? are the free? Like say i want to convert mp4 to avi or mkv and what not; where should i start my learnings >:D
