            Bug ID: 797110
           Summary: decodebin3: push flush-stop event to resume
                    multiqueue's task
    Classification: Platform
           Product: GStreamer
           Version: 1.14.0
                OS: Linux
            Status: NEW
          Severity: normal

Dear All.

Deadlock seems to be happened when upstream change(e.g. dynamic stream change)
and flush seeking is performed in several times in playbin3(decodebin3).

It means that
  1) auto plugging is in progress when upstream change
     and all parsepads are not exposed from parsebin.
  2) Either flush-start or flush-stop can be failed to travel to sink elements.
     Because multiqueue's sinkpad is not linked to parsebin and dropped.

As a result, muitiqueue's task is not resumed without flush-stop
and pipeline seems to be hangup.
