I am using window 7 and rg3-youtube-dl-2012.09.27 it was working fine utill I installed some other apps.

Now I get - ERROR: RTMP download detected but "rtmpdump" could not be run.

I think this has ned after installing the lastest Flash 11.4.

What can I do to get working again

Download http://rtmpdump.mplayerhq.hu/download/rtmpdump-2.3-windows.zip and install (copy) the exe files in a directory in your PATH, for example C:\Windows\System32

if you go into a commandline (with Win+R, cmd, Enter), and enter rtmpdump, what output do you get? And what output do you get if you enter echo %PATH% in the command line?

What I dont understand is that it was working before without rtmpdump installed. So why is it required now?

Here is the log of the commands

@phihag commented on GitHub (Oct 1, 2012):

Downloading works fine without rtmpdump if the video hosting service (e.g. youtube) uses HTTP to serve the video.

The output looks puzzling; running rtmpdump seems to work fine already. I'll try to reproduce it.

Can you provide the entire command line you're using to run youtube-dl?
