Såg nu att länken jag själv skickade med beskriver hur man gör för att ta reda på adresser och portar som används :-)

Finding the channels


  • Start a new capture in Wireshark
  • Grab the remote and tune the STB to a channel
  • * At this point, you will see the IGMP join request, followed quickly be a whole mass of UDP packets, coming from a private IP source, and headed to a multicast ip. These are the IPTV stream for that channel.
  • Pick a UDP packet (It shouldn't matter which one, they'll all be to and from the same location), and note down it's DESTINATION IP address and DESTINATION port.
  • * It's possible that Wireshark will try and be helpful supply the port's name for you in the packet listing. If you click on a packet, however, it will give you the number in the "User Datagram Protocol" header.
  • * For the first channel, open VLC, and choose "Media -> Open Network". Protocol UDP, address is the destination IP address, and port is the destination port. You should see on your computer screen the same as the feed from your STB. If so, congratulations.
  • Also note down the channel number and name. This will help later when it comes time to map your XMLTV IDs
  • Tune to the next channel, lather, rinse and repeat.

This process may take a while to complete, going through every channel, but by the end you should have a complete channel to IP/Port map.
