Fails to play: "Pykka.exceptions.ActorDeadError" about mopidy-youtube

[jodal]

This error is from the network connection code trying to stop the MpdSession actor because the connection has ended, only to find it is already dead. What would be interesting here is to see why it is already dead. I suspect that is to be found earlier in the same log.

The current log excerpt gives us nothing to work on, unless the issue can be easily reproduced by adding any YouTube playlist to the tracklist.

It happens for every youtube video I try to play, and the default-loglevel logs show nothing else.

Can you confirm that your system can play youtube streams, by issuing following command:

gst-launch-0.10 playbin2 uri=$(echo "https://www.youtube.com/watch?v=RuY4MSh1V-I" | python2 -c 'import pafy,sys;print(pafy.new("".join(sys.stdin)).getbestaudio().url)')

Will report back when I get home. It seems to be a python error though, it's thrown in if not data:.

Sorry, I totally forgot about this. Heres the output from running your code (albeit with a different song, yours can't be played in germany):

gst-launch-0.10 playbin2 uri=(echo "https://www.youtube.com/watch?v=xc96GfmtBB0" | python2 -c 'import pafy,sys;print(pafy.new("".join(sys.stdin)).getbestaudio().url)')

Okay, I installed gstreamer0.1-bad-plugins - playback works now. Thanks!
