#CastLab supports #FCast because it is an open source casting protocol, built as an alternative to Chromecast and AirPlay. You install the receiver app on a TV or computer (Android TV, Linux, Windows, macOS) and cast to it from CastLab.
Unlike DLNA, which depends on your TV, FCast can be installed on any supported device. Both are open and complement each other well.

#Adblocker detection on #YouTube is working far too well rn so I've been using #Grayjay from #Futo and it's excellent. It can cast ad-free to any other device with #Fcast and Futo make a bunch of other awesome apps too. Grab that shit before they make it ilegal. https://grayjay.app/
Grayjay App - Follow Creators Not Platforms

@crft as a fun workaround, you can install #FCast on your machine, then cast #GrayJay from your phone to your #Linux computer. It's not a perfect or even nice solution, but I've been doing it anyway and it works well enough. It's also not #Google only, you can get it on #FDroid using the #FUTO repo.
Does anyone know anything about #fcast? There doesn't seem to be a lot of resources about it. Just a website, a git repo and documentation. Not much is explained though.
Can I use this as an alternative to #chromecast by installing an app on the TV, or building a dongle with a Raspi for example?
