[Question] RTMP feed timed in web. Trying to open through URL.

[Amstiir]

Hello gentlemen,

I've been lurking the web to find an answer to this "problem" I'm having.
Here's the thing, I'm trying to get a live video feed stream to open
through some media player in my PC.

Problem is: I have sniffed the URL using NetTransport, and CooJah, and got the streaming URL: rtmp://200.141.78.68/cet-rio/3.stream

This is one of the streams given by traffic control, I've been trying to access this for longer than 10 seconds (time the website gives us to watch),
so I can tell when traffic is ok to get to work...
Anyhow, I've tried to open this URL in VLC player, BS Player, and WMP but they return error,
I want to open it instead of downloading. Is there any possible way to do that?

I'm sorry to be straight forward about this matter, I would have introduced myself in other cases, but I really need to know how this works.

Thanks for your time and expertise,
Amst.
