Miraclecast
Miraclecast is a software implementation of the Miracast protocol used for mirroring screens and streaming audio over Wi-Fi. It functions as a wireless display adapter, providing the capabilities of both a Wi-Fi display source that projects local content and a Wi-Fi display sink that acts as a wireless receiver for remote streams.
The project includes a peer-to-peer wireless network manager used to discover nearby devices and establish direct Wi-Fi connections. It specifically implements a wireless input backchannel, allowing mouse and keyboard events to be routed from a receiving display back to the source device.
The implementation covers the full lifecycle of wireless projection, including device discovery and scanning, session management through the Real Time Streaming Protocol, and the automation of network interface selection. It utilizes a hybrid transport model for control signaling and media transmission, managing wireless configurations via a system-level WiFi daemon.
Features
