           Summary: Gst.Event.parse_stream_start seems to not function
                    correctly
    Classification: Platform
           Product: GStreamer
           Version: 1.x
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base

Trying to parse the stream-start to get hold of the stream id. But I am getting
some weird errors.The code I have is this:
def padprobe(self, pad, probeinfo, userdata):
       event=Gst.PadProbeInfo.get_event(probeinfo)
       streamid=Gst.Event.parse_stream_start(event)
       print(event)
       print(streamid)

Which comes out of a :
src_pad.add_probe(Gst.PadProbeType.EVENT_DOWNSTREAM, self.padprobe, "user
data")

However when this runs:
(transmageddon.py:14655): GStreamer-CRITICAL **: gst_event_parse_stream_start:
assertion `GST_EVENT_TYPE (event) == GST_EVENT_STREAM_START' failed
<GstEvent at 0x7fc7b401eb00>
None

(transmageddon.py:14655): GStreamer-CRITICAL **: gst_event_parse_stream_start:

--------
To me it looks like the parse_stream_start doesn't validate properly and
resurns the GStreamer-CRITICAL instead of a False. Not sure what the crash at
the end is about.
