'''OpenGL extension NV.vdpau_interop
This module customises the behaviour of the
OpenGL.raw.GL.NV.vdpau_interop to provide a more
Python-friendly API
Overview (from the spec)
This extension allows VDPAU video and output surfaces to be used
for texturing and rendering.
This allows the GL to process and display the content of video
streams decoded using VDPAU.
Alternatively, the GL may modify VDPAU surfaces in-place, and VDPAU
may then process and/or display those surfaces itself.
This allows the GL to be used to combine application user-interface
elements with decoded video, implement custom video-processing
algorithms, etc.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/NV/vdpau_interop.txt
