FCast is an open-source casting protocol that instructs another device to play video and audio content. Like Google Cast or AirPlay, the sending device sends playback commands and a media URL so that the receiving device plays the content itself, but it is not tied to any company's certification or accounts, and the protocol specification and receiver implementations are public, so anyone can build supporting devices and apps. It was developed by FUTO and is used by the Grayjay app.
