timecodestamper - how to

yair
i am looking to stamp my frames with SMTP timecode. in order to synchronize multiple streams on server.
but i dont get what i expect, depay overwrites the timecode with its own.  
PAY=       (GstVideoTimeCode)15:09:14:28
DEAPY= (GstVideoTimeCode)00:00:05:18

it might be an error in the plug or an error in my brain


PAY 
timecodestamper pay is configured to
get the timecode from RTC - (source=5, Timecode from real time clock)
ALWAYS push timecode - (set=2, Always set timecode and remove upstream timecode)
and has post-messages enabled to show it.
 
DEPAY 
timecodestamper is configured to 
KEEP timecode -  (set=0. Never set timecodes)  
and has post-messages enabled to show it.

Re: timecodestamper - how to

yair
mybe the issue is with rtpgst discarding the metadata?
the following shows zero timecode

gst-launch-1.0 -m -v udpsrc port=5000 caps="$cps" ! rtpgstdepay ! queue ! timeoverlay time-mode=3 halignment=right ! autovideosink
