Glad you figured it out! One more nuance I discovered, there is a difference between podman-compose and podman compose The latter is equivalent to using docker compose Also in terms of community, their Discord (if you’re okay with using it) is quite responsive https://discord.com/channels/1072614816579063828/1087140957096517672

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.
