Add screen rotation feature when playing video with simple gallery

Components

For now playing video through simple gallery application is not problematic, it means smoothly without any constraints, but when I want to reverse my smartphone screen to watch video with full screen size was not able on this application. I can only watch videos with half the screen.

Proposal

I want a simple gallery app developer to add screen rotation feature when playing video, so later we can watch video in full screen state.

Mockups / Examples

Display for now

After added features my suggestion

Benefits

The benefit we can watch the video while reversing the smartphone. We can also watch full size video on our smartphone screen, so we can watch it comfortably. Almost all gallery applications and video player apps add this feature because it is very necessary.
