Problem Description

In fullscreen, videos only display in what VLC refers to as "Best Fit" where the video fits within the display, but the result is black bars on the side of the screen.

Proposed Solution

Add the ability to fill the screen with the video regardless of the difference of aspect ratio and screen size. It should either be able to be initiated by gesture or by a setting.

Here is what this looks like in VLC:

Best Fit

VS

Fit Screen

Alternatives Considered

The only alternative I could think of would be to simply not implement this feature, but obviously, that doesn't address the issue.
