Intriguing inconvenient using 'rtmpdump'

[ee7stream]

Hi! I'm new at the forum and I suffer from a little inconvenient using rtmpdump. I hope you can help me

I want to download the following video: http://elu24.postimees.ee/2699700/el...andra-nurmsalu

In order to do that I searched out the rtmp path of the video

rtmp://egress.cdn.mind.ee/postimees_vod/_definst_/mp4:vod/postimees/18.02.13.band_sandra.mp4

There is no problem if I reproduce the video with mplayer

$ mplayer rtmp://egress.cdn.mind.ee/postimees_vod/_definst_/mp4:vod/postimees/18.02.13.band_sandra.mp4

But when I try to download it with rtmpdump the command fail :c

$ rtmpdump -v -r "rtmp://egress.cdn.mind.ee/postimees_vod/_definst_/mp4:vod/postimees/18.02.13.band_sandra.mp4" -o "test.mp4"

So I would like to know why mplayer works but rtmpdump doesn't :c ... what am I doing wrong with the command? and how a working rtmpdump command looks like for this video in particular?

Thanks in advanced! c:

[ee7stream]

hasomaso thank you so much! ... the -W flag made the trick

I really thought that the -W flag was optional (actually I've been able to download other videos without it).

I know that it's not part of the original question but, in order to understand a little bit more, what is the purpose of the -W flag?

Thank you again for the help!
