Udpsink "Internal data flow problem" on MX6

Hi,

 

I'm using the following gstreamer pipeline to stream H.264 video from MX6Q/Linux to PC.

 

gst-launch -v tvsrc device=/dev/video0 capture-mode=0 ! 'video/x-raw-yuv,format=(fourcc)UYVY,width=720,height=576,framerate=25/1' ! mfw_ipucsc ! 'video/x-raw-yuv,format=(fourcc)I420, width=720,height=576,framerate=25/1'! mfw_deinterlacer ! vpuenc codec=avc   gopsize=2 ! video/x-h264,width=720,height=576 ! rtph264pay mtu=1024 ! udpsink host=192.168.0.68 port=5004

 

At the end of the output message, I got:

"

WARNING: from element /GstPipeline:pipeline0/GstUDPSink:udpsink0: Internal data flow problem.

Additional debug info:

gstbasesink.c(3626): gst_base_sink_chain_unlocked (): /GstPipeline:pipeline0/GstUDPSink:udpsink0:

Received buffer without a new-segment. Assuming timestamps start from 0.

"

 

Although the receiver pipeline on host (192.168.0.68) can correctly receive, decode and display the live video,

I am still wondering what "udpsink0: Internal data flow problem" mean.

 

Is there anything wrong here?

What is the root cause of the udpsink "Internal data flow" problem?

And is it possible to fix it?

 

Regards,

Robbie
