udpsrc element returns error "could not read from resource" in Windows

[william.l.metcalf]

I am trying to make a simple pipeline in Windows to send video via udp
from one computer to another.

The pipeline I am using to send looks like this - gst-launch
videotestsrc ! videoparse ! ffenc_mpeg4 ! udpsink host=192.168.42.68
port=52000

The pipeline I am using to receive looks like this - gst-launch udpsrc
port=52000 ! decodebin ! glimagesink

I run the second pipeline first and it just sits waiting for input on
the port.  I then run the first pipeline and I get the following output:
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
ERROR: from element /GstPipeline:pipeline0/GstUDPSrc:udpsrc0: Could not
read from resource.
Additional debug info:
..\..\..\..\..\Source\gst-plugins-good\gst\udp\gstudpsrc.c(588):
gst_udpsrc_create (): /GstPipeline:pipeline0/GstUDPSrc:udpsrc0: receive
error -1 (WSA error: 10040)
Execution ended after 15002000 ns.
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
Freeing pipeline ...

I am knew to using udpsrc/udpsink and this is my first test pipeline.  
Could someone please tell me what is causing this reading from resource
error?

Thank you,
William

I don't know the reason of your problem, but to me correct pipelines look as follows, at least this guarantees data delivery through RTP;

gst-launch videotestsrc  ! videorate ! ffenc_mpeg4 ! rtpmp4vpay ! udpsink host=192.168.42.68 port=52000

gst-launch udpsrc   port=52000  !  'application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)MP4V-ES, profile-level-id=(string)1, config=(string)000001b001000001b58913000001000000012000c48d8800cd0a041e1463000001b24c61766335332e302e30, payload=(int)96, ssrc=(uint)2944824259, clock-base=(uint)3591356201, seqnum-base=(uint)2983' ! decodebin ! glimagesink
