Whenever I click on a video and then enter full-screen mode with it, the video just plays in portrait mode, leaving the entire top and bottom dark. So I have to unlock the screen orientation, go in to landscape mode before I can watch the video in true full-screen. This happens in Chrome and many other browsers I have tried in the play store, the only browser that have a different web-video player is UC browser. It does all that I need when I watch a video (gestures, automatic landscape fullscreen...) but I don't like the browser itself. I prefer Chrome for browsing but not when it comes to watching embedded videos.
So is there anyway to "change" the default web-video player in Chrome? Or is it just impossible? I am using a Nexus 5 btw.
