Hi all,

   Is gst-gl-window-set-resize-callback available in python, particularly on raspberry pi ?

I couldn't work out how to get it working.

If not, is there another way to get a videos dimensions ?

filesrc

decodebin

While it is possible to use this (involving a *lot* of steps), the application is not really meant to know about GstGLWindow and that's not how to get the dimensions of the video, only of the backing window (which may be a different size).

You want to get the caps on glimagesink's sink pad and retrieve the width/height parameters from that.
