I think many of SDL1.2 is still applicable in SDL2 (I haven't touch the 1.2 for a long time, I may be mistaken). You can use the same tutorial to create a game in SDL2. After that takes the SDL2 tutorial (esp. the render-API which is not present in SDL1.2). At this point you should be good to go.
Also if you don't mind the non-video tutorial, Lazy Foo's Production has a good tutorial on SDL2. http://lazyfoo.net/SDL_tutorials/.
You might not need the video tutorial at all.
Last but not least, while the video tutorial is a good start, you might want to invest a bit more on a couple of game programming books. Look for good books on Game Engine design, or maybe Game Architecture. Theses books would teach you better high-level game coding without diving in too much details on APIs or platforms. I think "Game Architecture and Design: A New Edition" is pretty good even for beginners. I haven't on the hunt for books for quite a while now, there might be even better book out there...
