Save video clips from an rtmp-server onto harddrive on Mac OSX

[any ANONYMOUS forum user]

I'd like to save local on my harddrive video clips from an RTMP-server. I've tried rtmpdump 2.3 with no success.

Probably it's DFU-fault. Is there any other programs that can download video clips from an RTMP-server? I prefer GUI but is there no other option, CLI can be an alternative if I can receive some help, please. I'm not good at all on CLI-programs in Terminal.

The adress looks like this:
rtmp://fl1.c00928.cdn.qbrick.com/00928/_definst_/kluster/20081205/oa_43-1968-1216-teknisktmagasin

Jaksta for Mac is a GUI stream recorder for Mac OS X that allows to download RTMP streams.
