The real-time transport protocol (RTP) plugin will extract the Hosts, Payload Type, Synchronization source, 
Sequence Number, Padding, Marker and Client MAC address from every RTP packet found in the given pcap.

General usage:

    decode -d rtp <pcap> 
    decode -d rtp --no-vlan --layer2=sll.SLL <pcap>
