KSV,
Let the subject of this thread aside, I noticed that your rtmpdump version is:
RTMPDump v2.4 GIT-2015-12-23 (Compiled by KSV)
and mine is:
C:\MISC>rtmpdump
RTMPDump v2.4 GIT-2015-12-14 (Compiled by KSV)

ERROR: You must specify a hostname (--host) or url (-r "rtmp://host[

ort]/playpath") containing a hostname
Did I miss right download link somewhere for the latest release?
My Ubuntu also has it wrong:
j@j:~$ rtmpdump
RTMPDump v2.4 KSV-2015-12-14
