RTSP Streaming failing client side.

[tejas95]

I am using the test launch sample application in gst-rtsp-server to for streaming  as below:

server side:

./test-launch "videotestsrc ! videoscale ! "video/x-raw,width=720,height=576,format=I420" ! rtpvrawpay name=pay0 pt=96 "

client-side :
gst-launch-1.0 rtspsrc latency=50 location=rtsp://10.0.0.2:8554/test !  rtpvrawdepay ! videoconvert ! ximagesink -v

    The above pipeline works absolutely fine.

However when i change the source without changing anything , i.e

for the following pipeline...

server side:
./test-launch "v4l2src device=/dev/video2 ! videoscale ! "video/x-raw,width=720,height=576,format=I420" ! rtpvrawpay name=pay0 pt=96 "
client-side :
gst-launch-1.0 rtspsrc latency=50 location=rtsp://10.0.0.2:8554/test !  rtpvrawdepay ! videoconvert ! ximagesink -v

It throws the following error:

ERROR: from element /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0/GstUDPSrc:udpsrc0: Internal data flow error.
Additional debug info:
gstbasesrc.c(2948): gst_base_src_loop (): /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0/GstUDPSrc:udpsrc0:

client-side :
gst-launch-1.0 rtspsrc latency=50 location=rtsp://10.0.0.2:8554/test !  fakesink -v

the packets are getting transmitted for the above pipeline with fakesink.

unable to figure out the exact difference with the working pipeline with videotestsrc and v4l2src .
