Dear Lars!

Thank you for your help! Problem solved.

https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=4467

Br,

Hi,
That's probably because Wireshark can't determine the sampling rate.
Speex uses a dynamic payload type.
So Wireshark needs to have signaling info (SIP/SDP, H.323, ...) in your trace to figure out the sampling rate. Do you have this?

To Dev people: Actually we *don't need* the sampling rate in order to calcualte packet delta!
But in practice it seems we don't calculate it if we don't have a sampling rate. => could be fixed.

Regards,
Lars

	
	Hi all!
	
	I have a problem with rtp stream analyzer, i' m useing speex codec 8000hz sample rate and vbr. I see "0" in delta column every rows instead of the real delta values. Everything fine with PCMA, g711, g729, gsm... but speex.
	
	I tried the 1.2.2 and 1.2.6 and 1.3.2 dev versions... Same result, no delta values
	
	Can anybody help me with this problem?
	
	Br,
	Adam
