OpenGL.GLX.NV.present_video

OpenGL extension NV.present_video

This module customises the behaviour of the OpenGL.raw.GLX.NV.present_video to provide a more Python-friendly API

Overview (from the spec)

This extension provides a mechanism for displaying textures and renderbuffers on auxiliary video output devices. It allows an application to specify separate buffers for the individual fields used with interlaced output. It also provides a way to present frames or field pairs simultaneously in two separate video streams. It also allows an application to request when images should be displayed, and to obtain feedback on exactly when images are actually first displayed.

This specification attempts to avoid language that would tie it to any particular hardware or vendor. However, it should be noted that it has been designed specifically for use with NVIDIA SDI products and the features and limitations of the spec compliment those of NVIDIA's line of SDI video output devices.
