Remote playing large playlists make the clients hang

[ryancey 23]

I never managed to remote play playlists from Emby web app to an Android TV with the sideloaded (regular) app. The client just display the loader forever and do nothing. I'm talking about both ~15 tracks albums or ~1k playlists. When tried with my Android phone as target, it works but after a solid 2-3 minutes.

Playing a single track works but takes about 5 seconds. Stopping it is almost instant.

The web app, the phone app, and the TV app all connect to a local network Emby server, with the same host name.

The server is 4.8.0.80 and runs on docker.

Nothing unusual in the logs as far as I can tell. Here are the logs when shuffling favorite songs from the web app, remote controlling the Android app on the TV:

Hi, so which client hangs, the one controlling, or the one playing?

[ryancey 23]

The one playing.
