Hi, this is my first post about a feature I think LibreELEC could benefit from greatly in the future and that is FCast developed by FUTO.
What is FCast?
FCast is an open source protocol that enables wireless streaming of audio and video content between devices, supporting various stream types such as DASH, HLS, and mp4.
Unlike proprietary protocols like Chromecast and AirPlay, FCast offers an open approach, empowering third-party developers to create their own receiver devices or integrate the FCast protocol into their own apps.

Features
Simple
Open source protocol for audio and video content streaming
Support for various stream types (DASH, HLS, mp4)
Compatibility with Linux, Windows, MacOS, and Android
mDNS for device discovery
Extensive freedom for developers to create custom receivers

Sender-Receiver Interaction in FCast
In FCast, a "sender" is a device or software application that discovers and communicates with a "receiver". The sender, which can be a terminal client or an Android application, uses the FCast protocol to send media content to the receiver, such as a TV or media top box. The sender initiates the media streaming by connecting to the receiver, launching the media, and then the receiver begins playing the media. Once the media is launched, the sender can control the playback, allowing operations like pause, resume, seek, and volume adjustment.
A "receiver", in this context, is a software implementation running on various platforms (Linux, Windows, MacOS, Android, ...) that receives media content from the sender. It continuously provides updates to the sender about the current state of playback.

Receivers
Android native.
MacOS, Windows, Linux electron.
webOS
Tizen

Senders
Grayjay is a player that exposes multiple video websites as sources in the app.
Terminal sender allows you use the FCast protocol over the command line interface.
I think this could greatly improve the ease of casting on LibreELEC
