Why?

Unix world needs a CLI based CC monitoring tool that can accept various inputs. While piping MPEG-TS packets into dvbsnoop works, dvbsnoop does lots of other unnecessary processing using valuable CPU time. Using non-unix tools doesn't work either should you want to run headless. So CCmon was born.

Examples

$ CCmon 

Default socket mode:
  CCmon -group 239.3.1.1 -dev eth0

Using pcap capture:
  CCmon -group 239.3.1.1 -mode pcap -dev mirror

Using pcap capture with vlan and different port number:
  CCmon -group 239.3.1.1 -mode pcap -dev mirror -vlan 4 -port 666

Reading from file:
  CCmon -group myfilename -mode file

Additional parameters:
  -pidfilter X        Run only on specific PID, ignore others
  -stats              Report every 100000 packets received
  -cache              Cache last 5 packets for every PID, display on CC error
  -debug              Display all packets processed

Caveats

This is a piece of horrible code but it does what it promises. Bugfixes and refactoring welcome :)
