rtmpdump - cannot download video from stanford.edu

[rich_and_poor]

Hey there,

I'm hoping someone can point me in the right direction. I am trying to download a series of videos on Buckminster Fuller from Stanford Archives using rtmpdump 2.4. I was able to grab the URLs from the page source. The merged link which will play in a browser is:
http://collections.stanford.edu/buck...0/ss5_199_117t
-s "http://collections.stanford.edu/bucky/swf/mediaplayer.swf"
-r "rtmp://sul-streaming.stanford.edu/simplevideostreaming&autostart=true&id=bucky/480/ss5_199_117t"

I have tried putting various aspects of this URL into rtmpdump ... with -r -W -y etc. options, but nothing I tried has worked.

INFO: Connected...
ERROR: rtmp server sent error
ERROR: rtmp server requested close

Is anyone able to help me get my parameters straightened out so that I can download/save it? I used to have these videos on VHS back in the 90s, so am just wanting to download locally.

Thank you.
