Thank you,some times i got warning like this:

Traceback (most recent call last):
  File "/root/Record-Server/recorder.py", line 424, in on_eos
    self.pipeline.set_state(Gst.State.NULL)
AttributeError: Recorder instance has no attribute 'pipeline'

(python:9201): GStreamer-CRITICAL **: 
Trying to dispose element pipeline10, but it is in PLAYING 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
