good night sir ,

i replaced  R by Y 

i have  this problem 

the file contains rtp named g711.pcap ,you will find it attached 

and the script to execute to convert this pcap to wav is :

ssrc=$(tshark -n -r /home/amani/projet/PFE/g711.pcap -Y rtp -T fields -e rtp.ssrc -Eseparator=, | sort -u | awk 'FNR ==1 {print}')

sudo tshark -n -r /home/amani/projet/PFE/g711.pcap -Y rtp -Y "rtp.ssrc == $ssrc" -T fields -e rtp.payload | tee payloads

for payload in `cat payloads`; do IFS=:; for byte in $payload; do printf "\\x$byte" >>  /home/amani/projet/PFE/g711.raw; done; done

sox -t raw -r 8000 -v 4 -c 1 -e mu-law  /home/amani/projet/PFE/g711.raw  /home/amani/projet/PFE/g711.wav

can you please sir execute it ? and tell me where is the problem ?
