 Having created a .pcap file means we have all of the information we need to replay and analyse any captured stream. However before we access the stream we need to extract the Transport Stream from the .pcap file and save it as a .ts. Having created a .pcap file means we have all of the information we need to replay and analyse any captured stream.
