[rtmpdump] Help using rtmpdump

[Andrea]

Hi,

I am trying to use rtmpdump and I get the following error

rtmpdump -r
"rtmpe://groupemsix.fcod.llnwd.net/a2883/e1/mp4:production/regienum/Enquete-d-Action_c11324768_Marins-Pompiers-au-.mp4?e=1384721184&h=833a50418eda35e6ba02dace19179d1a"

RTMPDump v2.4

I have no idea what could be wrong here (wrong url, wrong swf, server version 6 vs 9...)
The handshake seems to indicate rtmpdump cannot support this server, but I am not sure what to
investigate.

Any idea?
