[FFmpeg-user] custom call

[oscar at medinasgroup.com]

Hello

I have a video sharing site (cumulus clips script) were people can  
upload videos; I have the video size limit to 550MB which is about 5  
minutes or 5 hours but that is not good for Me! I will like to have it  
so that the videos can't be more than 5 minutes (If it is, it will  
prevent the user from uploading it!), I was told at cumulus that this  
is possible by doing this:

"Add a custom call to ffmpeg to retrieve video's duration as soon as  
it is uploaded"

I hope to have been clear

Thank you in advance
