  GStreamer | gst-plugins-base | Ver: HEAD CVS
           Summary: rtspconnection is able to read incomplete messages
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: ext-tommi.myohanen at nokia.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


Message reading mechanism in gstrtspconnection.c::gst_rtsp_connection_receive()
contains multiple gst_rtsp_connection_read() calls which can be interrupted
with gst_rtsp_connection_flush() method. This can lead to situation where some
data has already been read from connection and then the receive operation is
canceled (e.g. when pipeline is paused). Now we have incomplete, partially
received RTSP message waiting, and this causes the next
gst_rtsp_connection_receive() call to fail with "Parse error".
