DirectFB (Direct Frame Buffer), now continued as DirectFB2, is a software library with a small memory footprint that provides graphics acceleration, input device handling and abstraction layer, and integrated windowing system with support for translucent windows and multiple display layers on top of the Linux framebuffer without requiring any kernel modifications.
[2][3] DirectFB is free and open-source software subject to the terms of the GNU Lesser General Public License (LGPL).
[citation needed] In 2006, a version of DirectFB was included in the software stack for the CE Linux Forum's Audio/Video Graphics Specification V2.
[5] DirectFBGL is an OpenGL extension for DirectFB/XDirectFB that uses Direct Rendering Infrastructure (DRI) in the Mesa 3D library to support OpenGL hardware acceleration.
Among the products that use DirectFB are LinuxTV, Ben Nanonote, the unreleased Palm Foleo mobile companion, the webOS operating system, Panasonic Viera Connect TVs and the Philips TVs based on jointSPACE.
