Hi..

I tried to play movie in processing 2.0b7 using opengl library but it gives me error.

Please don't suggest me for processing1.5 becuase i need to play a movie when a face is detected and i am doing this by OPENCV(opencv is not compatible with processing 1.5)

Need your valuable suggestions

Thanking you in anticipation. Here is error given by processing....

Hi Ja_Ha,

We're going to need more info from you, to start, some code showing how you get this error would be good. Also what platform are you on? What format is the video in?

thanks,

Looking at the error I think you are trying to use the GLGraphics library with a Processing 2.0 beta. Am I right?

If so, the bad news is you can't do this because the GLGraphics library is NOT compatible with Processing 2.0. The good news is most of the opengl functionality from the GLGraphics library has been incorporated into Processing 2.0. See: http://codeanticode.wordpress.com/
