Rails - May 2006 - Running shell commands from Rails.

Hi,

I want to be able to run shell commands from Rails.  I''m on the Windows
platform.  Would the code below work on Windows if IO.popen is called?  If
not, how would I run a shell command in Windows in order to run the ffmpeg
program?
**
*-----------------------------------*
*def encodeVideo opts, stream
IO.popen("ffmpeg #{opts}", ''w''){ |io| io.puts
stream}
end*

A pipe is opened and written to in the form of a command. Options are then
passed to the function that tell it which video to encode, the encoding
options, and the output file. The call looks like this:
*encodeVideo "-i /home/dennis/swing.avi -ar 22050 -ab 64 -f flv -s 320?240
/home/dennis/swing.flv", <<-END*
*-------------------------------------*

Thanks.
