Improving Video Streaming With GTK+ 3D Surfaces

GNOME

Within the open-source world, code examples and documentation can be particularly important in ensuring a lower barrier to participation. One developer, Jose Commins, has worked on creating demos, such as how to use OpenGL within GTK+. One of his projects is GtkGLApp, but now he's working on a new one involving real-time video streaming to GTK+ 3D surfaces.
GtkGLApp: Demonstration of OpenGL within GTK windows (using GtkGLExt) and the latest GtkBuilder format.It provides safe render-process locking and smooth timer-based rendering while being simple, efficient and easy to understand what is going on.

Jose has written in saying, "I am developing a more advanced version with real-time video streaming onto separate GTK+ 3D surfaces. Since this involves rarely-used (if at all) features of GTK+ it has revealed some very strange quirks with different graphic card drivers (e.g. flickering with ATI drivers, no flicker with nVidia, etc)."

Though due to not having a vast array of graphics hardware, he's hoping Phoronix readers will help in discovering Gtk+ and GPU driver bugs for this video implementation within GTK.

Jose has assembled an x86_64 version of this new GTK video test for those interested in running it and reporting the results (just post any feedback or questions in our forums) and he should be able to address it personally. The new GtkGLApp demo can be downloaded here.
