Debugging GStreamer
===================
If you really want to dig in and debug GStreamer behaviour, then check out the
`Debugging section
<http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/section-checklist-debug.html>`_
of GStreamer's documentation for your options. Note that Mopidy does not
support the GStreamer command line options, like ``--gst-debug-level=3``, but
setting GStreamer environment variables, like :envvar:`GST_DEBUG`, works with
Mopidy. For example, to run Mopidy with debug logging and GStreamer logging at
level 3, you can run::
GST_DEBUG=3 mopidy -v
This will produce a lot of output, but given some GStreamer knowledge this is
very useful for debugging GStreamer pipeline issues.
