           Summary: rtspsrc hangs when connecting over http tunneled rtsp
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base

The rtspsrc element sometimes hangs (forever) during connection setup when it
uses rtsp tunneled over http. 

It hangs in gstrtspconnection.c:gst_rtsp_connection_receive(). The problem is
that the gst_poll_wait is only supposed to return when it's ok to read from the
read socket. However, if some error has occurred on the write socket the poll
returns as well. Since there's no check on which descriptor caused the poll to
return a read from the read socket is done (resulting in nothing) and then a
new poll again. This repeats over and over again.
