If you share an external link it will usually require you to navigate away for that link. If you don't have "open links externally" selected it will open the proper page within the Facebook app.
If you upload one of your own videos from your phone it will be native to Facebook and will play in the app without navigating away. It will actually autoplay since this is usually on by default unless you turn it off.
If you're talking about Facebook for desktop I have no idea. Haven't used it in a long time.
