------- Comment #6 from Christian Prochnow 2006-05-02 12:26 UTC -------
ok, i tracked down the "join task" problem and fixed it ... it was caused by
setting the pipeline state in an event-probe callback.
however, the pipeline keeps hanging .. funny thing is that the backtrace shows
that two threads are streaming to the shout2 plugin ? (but i don't know the
threading details of gstreamer)
both threads keep hanging in _shout_timing_sleep ().
Many thanks for your help.
