[GStreamer (GNOME Bugzilla)]

--- Comment #4 from Florent Thiéry <florent.thiery at ubicast.eu> ---
Well, for the headers i just thought it could be an issue because the SDK
version of the headers is 10.3.1 where my system uses the current vendor
version 10.8

Here is the log

(gst-launch-1.0:4227): GStreamer-CRITICAL **: 
Trying to dispose element pipeline0, 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.
