I tried to download from http://www.c-span.org/Debates/ with rtmp-host.sh

And I got :

Administrator@pc ~
$ rtmp-host.sh
Killed flash player for clean dump. Hosts file reset.
Restart video then press enter here.

Can it be done ?

It is working now. Please note some big changes have been made to both my build of RtmpSrv and the rtmp-host.sh script as well. I will be updating the script with warning to reflect this, but for now you need to be using the RtmpSrv version as shown below.

$ rtmp-host.sh

Thanks, svnpenn, you cats at S-R are the best. Your streamlined command line worked like a charm for me!

I'm not quite up to speed on writing my own Adobe encryption reversal code yet, but maybe I'll get there in a few years! Speaking of which, could reversal be achieved more simply by Wiresharking one's DVR, for instance?

Better yet (as it seems to produce a cleaner capture)

rtmpdump -r "rtmp://s1g3v4ljhhuslz.cloudfront.net:443/cfx/st/mp4:2013/03/06/20130306105954002_hd.mp4" -o a.mp4

(in this case, the opening hour of United States Senator Rand Paul's filibuster, beginning at minute 48 of hour 11 [ file 20130306105954002_hd.mp4 ] of 2013-03-06 C-Span Senate proceedings and continuing with hours 12 through 24 [ files 20130306115954002_hd.mp4 through 20130306235954002_hd.mp4 )
