Android/Lineage OS and Screen mirroring ("Cast")
Android has native screen mirroring capabilities (when pulling down the status bar, there is a "cast" icon).
It uses for two technologies:
- Miracast (WiFi Display)
- Google Cast (Chromecast protocols CASTv1 and CASTv2)
Miracast is an open standard, Google Cast is proprietary.
Google Cast requires "gapps" on LineageOS. (proprietary google library)
Miracast
- Android 4.4 (2013) introduced support for Miracast
- Android 6 (2015) already removed support for Miracast on some Nexus devices
- Android 9 (2018) (Android Pie) has no more source code for Miracast since Google removed support for it
