I could not figure out how to zoom and pan the video when I set zoomAndPan to true. I tried enabling it in the Chewie Demo, but I did not observe any change in behavior. My assumption was that once zoomAndPan is specified as true that I'd be able to do a two finger pinch or expand gesture to zoom in and out of the video. However, that did not work for me on either Android or iOS. If this is actually working, maybe the documentation needs to be updated to explain how it functions.
