When I try this, I see the following output at the command line:

$ extract-rtmp-flv file.tcpdump file.flv
Parsing tcpdump output for file.tcpdump

extract-rtmp-flv: Unexpected tcpdump header line, line 1:
15:04:37.148997 IP (tos 0x0, ttl 53, id 0, offset 0, flags [DF], proto TCP (6), length 60)

I'm using:
tcpdump --version
tcpdump version 4.0.0
libpcap version 1.0.0

Any suggestions?

Thanks.
