Hey !
I try to run a basic pipeline using opengl like that :
gst-launch-1.0 gltestsrc ! glimagesink
My application crash and the last message on my console is :

--------------------------------
So I try to set some environment variable like :
GST_GL_PLATFORM or GST_GL_WINDOW but unsuccessfull.
I'm new to opengl library but I have made some simple tutoriel on it so I
have little experience in it.
Maybe I made something wrong...
What I should do to launch successfully this pipeline ?
Thanks.
