"System could not find the specified file"

I am trying to use nflvid. I followed the instructions for Windows installation, but when I ran this script: C:\Python27\Scripts> python nflvid-footage --dry-run --season 2012 --teams MIN -- "C:\Jacob\nflvid\footage\vikes\full" I got this error:

Any help with this is greatly appreciated.

Thanks

The error message tells you what is wrong. Your system cannot find the rtmpdump executable. You need to install that.

I don't use Windows so I can't really help much further. Frankly, I'd be surprised if this still works even if you got rtmpdump installed.
