Hi Robert,
Thx for your help! I'm having trouble running the example. It seems I need
some extra plugin to read a avi or mpg file. I'm running OSG on windows.
I've built all the available plugin that comes with osg. Am I missing
something ?
Thanks again!
Jerome

Hi Jerome,
Have a look at the event handling in the osgmovie example as this does
exactly what you are looking for.
Robert.
