0:00:00.037768168 5777 0xd47450 DEBUG faad
gstfaad.c:376:gst_faad_set_format:<faad0> faacDecInit2() failed
(gst-launch-1.0:5777): GStreamer-CRITICAL **:
Trying to dispose element faad0, but it is in PAUSED instead of the NULL state.
You need to explicitly set elements to the NULL state before
dropping the final reference, to allow them to clean up.
This problem may also be caused by a refcounting bug in the
application or some element.
