RE: How would I go about getting the duration of a Windows MediaFileusing Lua?

["Mike Vidal" <MVidal@...>]

I'll probably end up using this approach.
How do I capture the output of a command line program with os.execute ?  
Is the only way to redirect the commands output to a file then read that?

Here's an interesting utility here http://mediainfo.sourceforge.net/en that I think I'll end up using.

It's pretty easy to get this with javascript or vbscript

This is probably to tedious but what about using an external app,
"mplayer -identify thefile.wmv" come to mind, to extract the info into a
temp file.  It will also give you some more info - res, fps, video
codec, audio codec etc.
