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 http://www.microsoft.com/technet/scriptcenter/guide/sas_fil_lunl.mspx -----Original Message----- From: lua-bounces@bazar2.conectiva.com.br on behalf of Hans Sent: Fri 11/4/2005 1:49 AM To: Lua list Subject: RE: How would I go about getting the duration of a Windows MediaFileusing Lua? 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. On Thu, 2005年11月03日 at 14:31 -0800, McMorris, Patrick wrote: > Hello Mike, > > I don't believe that you will find what you are looking for directly > within the Lua language yourself.
