Greetings, fellow FOSS fanatics! I've been scouring the internet in the past month for any kind of open source implementation of the Miracast protocol that could run on Android (or Android TV) as a receiver with no luck.

I installed LineageOS 20 (Android 13) on my TV Box (Dynalink 4k / wade), but even though LineageOS for phones has retained the Miracast sender functionality after Google removed it from AOSP in favor of their stupid proprietary Chromecast, it seems the ATV version hasn't received a similar treatment as a receiver.

I think this is a real shame and a massive oversight, forcing us privacy-loving folk to either use Goolag services for Chromecast (if you're lucky enough that your device has it built-in), or resort to disgusting proprietary apps filled to the brim with ads, tracking and in-app purchases.

Is there a reason no FOSS Miracast / WifiDisplay receiver has ever been developed for Android? I found receivers made for Raspberry PI and Linux, but no Android, could one of those be adapted or compiled for Android? Note that I'm not a developer, so I might be talking mumbo-jumbo, sorry if that's the case :D
