RTP Analysis and Assessment

Question

Hi I have captured RTP stream and now trying to play it in the inbuilt wireshark player. It is reporting "Drop by Jitter Buffer", "Out of Sequence" and Wrong Time Stamp. But in the player how do I know which one is showan as what. I have Red, Yellow color lines in the player and see Choppy voice but not able to interpret/separate these issues/packets.

This part of the RTP player code tells you what's going on:

                        if (status == S_DROP_BY_JITT) {
                                gc = red_gc;
                        } else if (status == S_WRONG_TIMESTAMP) {
                                gc = amber_gc;
                        } else {
                                gc = rci->draw_area->style->black_gc;
                        }

So thats:

Red for dropped packets
Amber for wrong time stamps
