Trying to use rtmpsuck but failing miserably. - Audio/video stream recording forums

Hi!
I'm newbie in record streaming videos and i want to record streming videos from a website, so i'll start trying to use rtmpsuck/rtmpdump. I didn't create this topic in "rtmpdump" because i didn't even started to use it. I'm stuck in rtmpscuk.

So here my first try:
1- Open the streaming video using Firefox.
2- Run as superuser rtmpsuck
3- Nothing happens with rtmpsuck
The output is:

Streaming on rtmp://0.0.0.0:1935

I've read i have to use iptables first to redirect the streaming to port 1935(which is weird because i thought it already watching that port).
Here my second try:
1- As superuser run the following command:

Code:

iptables -t nat -A OUTPUT -p tcp --dport 1935 -m owner \! --uid-owner root -j REDIRECT

2- Open the streaming video using Firefox.
3- Video doesn't open.

I tried to read some tutorials in internet and Youtube but they are very old.

Could you please help me?

Also, probably the videos i want to record have tokens that stay active for 1:30min.
Will rtmpsuck/rtmpdump "bypass" it?

I'm usinf Arch Linux, iptables, rtmpsuck/rtmpdump all last versions.
