dashcast: Namespace urn:x-cast:com.madmod.dashcast is not supported by current app #972

Open dtreskunov opened 1 month ago

dtreskunov commented 1 month ago

I have installed DashCast by following the following guide: google-nest-hub-as-dashboard-with-dashcast-add-on

It worked a few times, but now I'm seeing the following error: Namespace urn:x-cast:com.madmod.dashcast is not supported by current app

The error can be replicated by running examples/dashcast_example.py in the master branch (a786600):

After calling media_player.stop the error went away. I suspect restarting the device would also fix it.
