            Bug ID: 793213
           Summary: blocking probe and flush events issue
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)
          Assignee: gstreamer-bugs at lists.freedesktop.org

test application

The following problem has been observed:

a blocking probe (GST_PAD_PROBE_TYPE_BLOCK_DOWNSTREAM | 
                  GST_PAD_PROBE_TYPE_DATA_DOWNSTREAM |                          
                  GST_PAD_PROBE_TYPE_EVENT_FLUSH)

is installed on the source pad. When the pad is blocked, a flushing seek is
performed. No flush-start/flush-stop events are received in the probe.
Is the probe installed in an incorrect way?

The attached dummy test application exposes the problem.
