A new V4L2 core framework: an overview and future plans



This talk gives an overview of the new core V4L2 framework that was created in the past year, and the future developments planned for this framework.


Since the 2008 Plumbers Conference a lot of work was put into a new V4L2 core framework. Much of that framework was designed during that conference and the initial version was merged in the 2.6.30 kernel. This talk describes what was done in the past year and what is planned for the future. This part of the talk welcomes contributions from the audience since this will help me decide on which part to focus first.
