Video playback options

Video playback options Sometimes videos play back where you have the ability to double click them and the video will go to full screen, when in this mode it also gives you the two circles with 10 seconds or 15 seconds that you can fast forward or rewind. I prefer this over the other option, Which lacks the two circle fast-forward/rewind button’s and does not allow for a complete full screen meaning there’s black bars on top and bottom when iPad or iPhone Is horizontal. How do I choose which video player style I prefer?
