You wouldn't. Keep it in GL.

For anything related to video, assume that you will never get access to the 
actual pixels, either because of DRM or because it would just be too slow for 
the CPU. Any and every transformation that you need to do with the video must 
be done with OpenGL, directly on the GPU.
