[Feature Request]: Fill Screen Option

[pphenric]

Preflight checklist

• I have searched the issue tracker for a bug report that matches the one I want to file, without success.
• I have searched the features list for this feature, and I couldn't find it.
• I have checked that I'm using the latest stable version of the app.

Problem Description

Currently there is no option to fill the screen while full screen landscape, inside the integrated player.

Proposed Solution

Have an option inside the integrated player, to fill the screen (match the device's max width, while keeping same aspect ratio)
