recloudstream/cloudstream ? reverse-engineered prompt

I'd like to build a media center app for Android. The main idea is that it should be a flexible, ad-free player that can stream from different sources. It shouldn't come with any content itself, but instead should have a system for extensions or plugins. This would let users add their own sources to watch videos from places like YouTube, Twitch, or even public IPTV channels.

The app needs to work on both Android phones and Android TV devices, and it definitely needs to support Chromecast. It should be really clean, with no ads or user tracking. I also want users to be able to bookmark content to watch later. The whole point is to give the user freedom to customize where their media comes from without being locked into a single ecosystem. Please build it with Kotlin.
