           Summary: rtspsrc tries to stream application/x-wms-rtx

Please describe the problem:
The rtspsrc element opens an RTP/RTCP session for every "media" present in the
RTSP/SDP (in reply to RTSP/DESCRIBE). In the case of the Windows Media
platform, there is a media with a MIME type of "application/x-wms-rtx", which
is Micro$oft-specific and does not send any RTP packet.
After 5 seconds (default timeout), rtspsrc complains that no packet is received
on the stream and closes the whole session.

Steps to reproduce:
1. Have a running WMServer with a .wma file to be streamed
2. $ gst-launch rtspsrc location=rtsp://wmserver/file.wma ! fakesink
3. After 5 seconds, the following message appears and rtspsrc closes the
connection (with a TEARDOWN):

Could not receive any UDP packets for 5.0000 seconds, maybe your firewall is
blocking it. Retrying using a TCP connection.


Actual results:
rtspsrc wrongly concludes that the whole session is invalid and closes it.

Expected results:
The session carries on for the other streams (ex: audio, video, etc.)

Does this happen every time?
Yes

Other information:
The easiest solution I think is to close only the RTP session instead of the
whole RTSP sessions. If all RTP sessions are closes, then rtspsrc indeed knows
that this session is invalid/empty and should be closed.
