I have Jellyfin installed on a remote machine, connected to my laptop and phone via Tailscale. Is it possible to cast from that machine to a gen 2 Chromecast?
From the Jellyfin instance installed on my laptop, in the same LAN, I can authenticate from the phone and cast to the Chromecast, so all the pieces work.
I have tried announcing the subnet from the laptop (--advertise-routes=192.168.1.0/24), with IP forwarding etc. The remote machine accepts the route and can ping the Chromecast (192.168.1.100). From the phone I can connect to the server and start casting. The screen shows the Jellyfin logo, but playing anything has no effect.
Has someone managed to make it work?
EDIT: As I feared, it seems it’s not possible. I can’t change the routing table of my ISP’s router, so the Chromecast can’t reach the remote server.
I’ll try to find a newer Chromecast, or maybe just get a Raspberry and install the full client there. Thanks everyone!
Confirmed that this works! Setup: Tailscale on android phone, Chromecast Ultra without tailscale. Edit settings in Jellyfin app to play on external player. Choose VLC as external player and then cast from VLC to Chromecast Ultra. Caveat: casting a stream with subtitles does not work.
