Device Information / Hardware
The Broadcom 97425 is a powerful dual core MIPS set-top-box reference design. The hardware is capable of running QtQuick2/SceneGraph. Broadcom provides an optimized version of DirectFB for 2D graphics, input and image decoding. The multimedia architecture is based on GStreamer. Broadcom provides pipeline elements to access their hardware.
Software provided by Broadcom
Broadcom provides customers with the AppLibs and RefSW. The last tested version is 20111222 for the RefSW 20111222. The rockford 3D library needs to link to DirectFB to avoid missing symbols when loading the DirectFB/QPA plugin. The patch was provided to Broadcom and should be included in future versions.
