GL_INVALID_OPERATION on glGetTexImage
Dear GL developers,
I'm trying to use the function glGetTexImage on textures generated from a movie. For some reason I get the error GL_INVALID_OPERATION and am clueless on how to solve it, what is causing it. Offcourse the array in which I want to store the data is empty.
The code that's responsible for drawing my textures is ->
After I try to apply glGetTexImage the texture does get drawn and displayed correctly.
If more code/info is required I'll be more then happy to suply it. Thanks all!
Re: GL_INVALID_OPERATION on glGetTexImage
When I change the call to:
glGetTexImage(target, 0, GL_RGB, GL_UNSIGNED_BYTE, buffer);
My error is gone, nevertheless my array's still left blank. Help is really really appreciated on this one.
EDIT: Applied glReadPixels and is working now.. Seemed like it was using some sort of PBuffer deep down
