The same is true of ffmepg. The api documentation even links to the source of the bins so you can read the example code. To pick on ffplay, I think it most clearly illustrates this - with the bare minimum rendering context to get video on the screen but clean code continously updated to reflect the api's best practices, and an invaluable resource when I was writing an embedded player for a game.
