timecodestamper - how to

[Yair Reshef]

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.
