 <p>This project is a GPLv3 unix AirPlay server which now also works on macOS. Its main use is to act like an AppleTV for screen-mirroring (with audio) of iOS/macOS clients (iPads, iPhones, MacBooks) in a window on the server display (with the possibility of sharing that window on screen-sharing applications such as Zoom) on a host running Linux, macOS, or other unix, using Apple’s AirPlay Mirror protocol first available in iOS 5. (Details of what is known about the AirPlay2 protocol can be found <a href="https://github.com/SteeBono/airplayreceiver/wiki/AirPlay2-Protocol">here</a> and <a href="https://emanuelecozzi.net/docs/airplay2">here</a>).</p>
 <p>The UxPlay server and its client must be on the same local area network, on which a <strong>Bonjour/Zeroconf mDNS/DNS-SD server</strong> is also running (only DNS-SD “Service Discovery” service is necessary, it is not necessary that the local network also be of the “.local” mDNS-based type). On Linux and BSD Unix servers, this is usually provided by <a href="https://www.avahi.org">Avahi</a>, through the avahi-daemon service, and is included in most Linux distributions (this service can also be provided by macOS, iOS or Windows servers).</p>

The initial connection to the client can be in AirPlay audio mode, or an initial Airplay Mirror connection can be changed to Airplay audio by closing the Mirror window and reconnecting in audio-only mode (this changes back to AAC audio if screen mirroring is restarted).</em></p>
 <p>UxPlay 1.40 is based on https://github.com/FD-/RPiPlay, with GStreamer integration from https://github.com/antimof/UxPlay. (UxPlay only uses GStreamer, and does not contain the alternative Raspberry-Pi-specific audio and video renderers also found in RPiPlay.) Tested on Ubuntu 20.04, Linux Mint 20.2, OpenSUSE 15.3, macOS 10.15.</p>
 <p>Features: 1. Based on Gstreamer. 2. Video and audio are supported out of the box. 3. Gstreamer decoding is plugin agnostic. Uses accelerated decoders if available. VAAPI is preferable, (but don’t use VAAPI with nVidia). 4. Automatic screen orientation.</p>
