            Bug ID: 746442
           Summary: rtprtxsend: Maybe broken stream lock handling
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: All
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: slomo at coaxion.net
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Currently rtprtxsend is sending data and events from the sinkpad streaming
thread, and from its own srcpad task. The srcpad task holds the stream lock of
the srcpad all the time, and pushing data/events will take the stream lock of
the peer pad.

I'm not sure if the attached patch is really necessary, maybe by taking the
peer pad stream lock everything is good already... but maybe not. Maybe what
can happen is that we store serialized events out of order on the srcpad
itself or something.
