rtmpsrv and dump for mac? - Audio/video stream recording forums

Hi im new to this and been trying to figure out a way to download
a rtmp stream from a site. In the webpage source page the filename
is visual and its and mp4 file. I havent located the full path to the
file so i searched for an program to grab the url. This lead me to rtmpdump combined with rtmpsrv. But where do i find rtmpsrv
for mac? ive downloaded a binary of rtmpdump from the official download page but cant find the rtmpsrv anywhere. And is there
a simple step to step guide in using these two programs? Iam actually
new to the whole use of terminal thing too. Oh and i ment to use it
on my mac.

Thanks
