RTMPDUMP in Linux not working.

[claudiogc]

Hi, people!

I would like to capture/record some video streams from o porn website and to do that i followed this tutorial:
https://www.youtube.com/watch?v=8PuUnQCS7DQ

So, i'm using Debian Wheezy last version, and i downloaded Wireshark, VLC and rtmpdump. So, take a look at the "Stream Content" option of wireshark.

So, looking for something that begins with rtmp:// i found this:

rtmp://dolphin.cameraprive.com.br/cameraprive_main/6188

Then this is how i tried to capture/record the video and the output:

claudio@claudiogc:~$ rtmpdump -v -r "rtmp://dolphin.cameraprive.com.br/cameraprive_main/6188" | vlc -
VLC media player 2.0.3 Twoflower (revision 2.0.2-93-g77aa89e)

Another try:

claudio@claudiogc:~$ rtmpdump -r "rtmp://dolphin.cameraprive.com.br/cameraprive_main/6188" -o test.mpg

How can i do what i want?

Thanks!
