video_source

---

This extension provides the capability to source pixel data from a video stream (for video textures).

A new type of GLXDrawable ( GLXVideoSourceSGIX) is introduced which represents the drain node of a Video Library (VL) path.

A GLXVideoSourceSGIX may be specified as the read parameter to glXMakeCurrentReadSGI() to indicate that pixel data should be read from the specified video source instead of from the framebuffer.

A GLXVideoSourceSGIX may only be specified as a read drawable.
