Hello guys,

I am using tshark to extract G729 payload from rtp stream by command

tshark -r call.pcap -Y "rtp && rtp.ssrc==0x10813c7b" -T fields -e rtp.payload >>data.raw

Then I removed the new line character, decoce payload and played but I could only hear the noise. When I compare the histogram with the sound created by wireshark, I can see it has some similarities. Is wireshark automatically adding lost packets to the rtp stream?

Regard,

Kien
