gstreamer-1.0 appsrc sample example

[Biswajit Panigrahi]

Hi Sebastian,
Thank a lot for debugging .

Now both fakesink as well as filesink location=testSRC1.mpeg in appsrc
works fine.
But while streaming over udp ,its getting failed.

app->pipeline = gst_parse_launch("appsrc name=mysource ! videoconvert ! vpe
num-input-buffers=8 !  ducatimpeg4enc bitrate=4000 ! queue ! rtpmp4vpay
config-interval= 10 pt=96 ! udpsink host=192.227.1.20 port=5000 ", NULL);

I am getting continuous message like :
(GST_Final:1639): GStreamer-CRITICAL **: gst_segment_to_running_time:
assertion 'segment->format == format' failed

Any idea what could be the root couse for this.
I have attached the complete code also in  this mail.

Regards,
Biswajit
