| | '''OpenGL extension SGIX.video_source |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GLX.SGIX.video_source to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension provides the capability to source pixel data from a |
| | video stream. 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. |
| | |
| | The official definition of this extension is available here: |
| | http://www.opengl.org/registry/specs/SGIX/video_source.txt |
