shantiq,
You can't use bat999's rtmpdump script!! because the rtmpe link has "auth" string and cannot be used 5min after is generated!! You should get a new auth string for your self!!
Code:
rtmpdump -r "rtmpe://ak.securestream.channel4.com:1935/4oD?auth=da_dpasa_bDdfcKbObAahcJbAbjdhbWaicC-bpkhp9-eS-ixU-
