Hi, Due to my research concerning jitter buffer, I tried to use Wireshark to evaluate a number of packets dropped by buffer. However, there is no description of jitter buffer implementation in Wireshark. Therefore, I have verified source codes for version 1.2.4. I analyzed file gtk/rtp_player.c and function decode_rtp_stream.
And, I have few concerns. There is no real buffer, but only a number representing hypothetical buffer size (variable jitter_buffer). Packets are “dropped” when variable diff is greater than jitter_buffer (line 758). Variable diff represents absolute value in ms between real time of receiving this packet and time when this packet should be received (line 742). I would be very grateful if somebody who know this part of code could confirm these?
