I want to get every OpenGL frame from an animation with glReadPixels() and convert the data to OpenCV::Mat. I know that glReadPixels() gets the data by rows from the lower one to upper one, from left to right. On the other hand, OpenCV stores the data differently.

Does anybody know any library or any tutorial/example that helps me to convert data from glReadPixels to a OpenCV:Mat in C++?

SUMMARY

 OpenGL frame      ----------------------->        CV::Mat

Data from left to right,                    Data from left to right,
bottom to top.                              top to bottom.
