The topic of this talk was ''Video output from a Linux desktop application''
after extended research we built a demo application in four flavours
(XVideo, SDL, OpenGL legacy / modern).
This research project was set off by our immediate needs for a setup
to show computed video pixel data in a viewer window in the GUI; the
investigated technologies should work at present and in the near term
future (yet leaving out Vulkan and Wayland)
