[Libva] Enabling hardware acceleration for Intel GMA x3100

[Abhijeet Rastogi]

Hi guys,

On my desktop, HD Videos sometimes lags (horizontal lines) when the camera
moves too fast in the video. Searching on google said something about
enabling hardware acceleration.

I checked the pdf here
specs<http://download.intel.com/products/graphics/intel_graphics_guide.pdf>
&
it has something written about HD video playback.

So, I checked if I had libva package installed. It was installed but
libva-driver-intel was not installed. So, I installed it.

I did a restart & issued the command vainfo.

shadyabhi at archlinux ~ $ vainfo
libva: VA-API version 0.32.0
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/dri/i915_drv_video.so
libva: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
shadyabhi at archlinux ~ $


shadyabhi at archlinux ~ $ pacman -Ql libva-driver-intel
libva-driver-intel /usr/
libva-driver-intel /usr/lib/
libva-driver-intel /usr/lib/dri/
libva-driver-intel /usr/lib/dri/i965_drv_video.so
libva-driver-intel /usr/share/
libva-driver-intel /usr/share/licenses/
libva-driver-intel /usr/share/licenses/libva-driver-intel/
libva-driver-intel /usr/share/licenses/libva-driver-intel/COPYING
shadyabhi at archlinux ~ $


So, it's something like vainfo is searching for
/usr/lib/dri/i915_drv_video.so but the installed package has supplied
/usr/lib/dri/i965_drv_video.so.

After going through the link http://intellinuxgraphics.org/h264.html, I
have also compiled libva with --enable-i915-driver option.

What could be wrong? Any help would be greatly apprec
