A package is being provided for users to test Intel's 2.9.1 video driver on OpenIndiana oi_151a. The Intel 2.9.1 driver supports MPEG2 XvMC (X Video Motion Compensation) on Intel GPUs (i.e. Intel i810 through Intel HD (Clarkdale/Arrandale) GPUs). This feature allows video programs to offload motion compensation and iDCT (Inverse Discrete Cosine Transform) portions of MPEG-2 decoding to the Intel GPU hardware. XvMC greatly reduces CPU utilization when playing back MPEG-2 video. In theory it should also reduce bus bandwidth requirements. Dramatic performance savings are seen when playing HDTV (720p/1080i) and Blue-Ray (1080p) video on laptops or desktops with slow CPUs. The OpenIndiana SFE project provides both current releases of Mplayer and VLC which can playback 1920 x 1080 (1080p) high definition videos on Intel GPUs using XvMC.

To enable XvMC in /etc/X11/xorg.conf add the option:
