I am getting Got missing-plugin message: description:audio/x-unknown decoder when I attempt to play this video. Half of my problem with this bug is that it will not play the stream, the other half is that mopidy gets stuck on this track and will not advance to the next one without calling PlaybackController.next(). Also note that this problem happens with other videos as well.

I have isolated my system configuration to the following Dockerfile to reproduce the environment:

FROM python:2.7
MAINTAINER jghibiki <jghibiki.games@gmail.com>

RUN wget -q -O - https://apt.mopidy.com/mopidy.gpg | apt-key add -
RUN wget -q -O /etc/apt/sources.list.d/mopidy.list https://apt.mopidy.com/mopidy.list
RUN apt-get update && apt-get install gstreamer0.10 gstreamer0.10-plugins-bad gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-plugins-ugly gstreamer1.0 gstreamer0.10-plugins-bad python-requests python-setuptools python-pafy mopidy mopidy-youtube --assume-yes

ADD ./mopidy.conf /root/.config/mopidy/mopidy.conf

RUN /usr/bin/mopidy deps

CMD /usr/bin/mopidy -v

The result of the mopidy deps call made while building the docker image:

EDIT:

It maybe helpful to note that:

You might be able to fix this by running: gst-installer "gstreamer|0.10|mopidy|audio/x-unknown decoder|decoder-audio/x-unknown, codec-id=(string)A_OPUS"

does not work on this system as gst-installer does not exist (there is a gstreamer-codec-installer) however it requires an X org display to attach to making it in-ideal for headless environments.

You are missing opus decoder you can either install that or try this branch https://github.com/mopidy/mopidy-youtube/archive/force-ogg (pip {unistall,install} https://github.com/mopidy/mopidy-youtube/archive/force-ogg.zip)

I tried both alternatives with no results (as well as both together). Installing the opus decoder made absolutely no change to the log output. Installing the force-ogg branch made it so that nothing would happen when Playback.play was called.

Have you tried upgrading pafy to 0.3.74?

@jodal That seems to have done the trick. Debian ships papfy 0.3.6X so forcing 0.3.74 into dist-packages solved the issue.
