Created a tool that lets you rotate, flip, and mirror any cors-compatible website. It's designed mainly for teleprompters.
There are drop downs to switch between source modes, rotation, transformation
It will store the last used settings automatically, and restore automatically on reload. simple
Passing discord or chat pop out links will be auto-converted into a cors-friendly embed version of the chat pop out
(optionally) it can take &link with a URL value, or &twitch to pass a user name
Hide menu button; to show the menu again, just reload the page
This works great for reading chat out from a teleprompter or even just for VDO.Ninja feeds. VDO.Ninja works great for sending remote teleprompter feeds to something like a Firestick 4K Max, and this teleprompting website should make it easy to flip/invert/mirror the video as needed.
