How to play a full folder ? Kindly guide
There is an official VLC add-on in the Settings > Add-ons > ADD-ON STORE.
This installs and runs the add-on under the HA OS. You may have to configure its inputs and outputs in the add-on’s Configuration tab. Then you start it (check the log tab for errors and if all looks good, enable the watchdog and start on boot).
With the add-on running (and this part is key), you go to Settings > Devices & Services, and should have the VLC telnet integration auto-discovered. You add it and there’s not much to do. Everything should just work out of the box - or at least it did for me on 3 HA OS installs so far.
If you’ve some VLC integration manual install pre-dating this, you may have to take it out and clean that up very thoroughly and redo this procedure.
