Wireshark · Wireshark-dev: Re: [Wireshark-dev] RTP raw file

[Jaap Keuter <jaap.keuter@xxxxxxxxx>]

Hi,

Have a look at rtp_analysis.c

The idea is to 'tap' the RTP packets and write out the payloads into a file.
That gives you the stream as seen on the network, actual voip applications use 
a jitterbuffer to recover from sequence errors and changing network delay.

Thanx,
Jaap
