Whenever you tap on a video in the mobile Safari web browser, such as on YouTube or otherwise, iOS displays that video in a familiar interface called the AVPlayer, which appears in the screenshot example above.
Like most video players, iOS’ native AVPlayer provides only the fundamental controls to and get things done, but with the help of a newly released and free jailbreak tweak called AVPlayerPlus by iOS developer Tr1fecta, you can enjoy several more luxury controls in the native AVPlayer interface that Apple never bothered to provide to you out of the box.
