How to reset time in elements when pipeline is running ?

[stic at free.fr]

What I understand is that I need to send a new segment. Is it correct ?
I can see from gnlghostpad that they set segment.base with next_base_time ... but what it next_base_time ?
So do I have to send a new segment and changing its base time to last pipeline clock ??

thank you

Have a look at gnlghostpad.c. The translate_incoming_segment() and 
translate_outgoing_segment() method. There is also method to translate 
seek. The general idea is that if you change the source, the new segment 
will start from 0 again, so you need to make it seamlessly continuous by 
adjusting the segment offset. You use might be a little simplier then 
gnl though.
