Following the recommendations I got, I set up a #NodeBB forum to discuss the projects #Fedilab, #Holos, #CastLab and #Fedle.

Each category federates over #ActivityPub, so you can follow it directly from your Fediverse account: @fedilab, @holos, @castlab, @fedle.

More details: forum.fedilab.app/post/2

#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.
