Presentation given during Bossa Conference, held in Porto de Galinhas - Brazil in March 11th 2009.Abstract:Today's Linux kernels have out-of-the-box very good support for real-time computing. On embedded/mobile devices and on the desktop the availability of real-time is much underused. For tasks like multimedia playback, animations and audio interfacing it brings great benefits, reliability and a smoother user experience. However it can sometimes be very tricky to use properly -- especially since in most applications you need to make compromises all over the place and it is hard to know where and how to start. In this talk Lennart focus on how to develop real-life applications with the Linux real-time APIs from a decidedly practical userspace perspective.If you do media playback, animations or audio interfacing on embedded/mobile devices or on the desktop make sure to drop by to learn a thing or two about how to make your applications perform well and smoothly under all circumstances.
