VLC very slow when using libva/vaapi on a Sandy Bridge HD3000

Hi,

this Problem is driving me crazy. On my X220t Laptop i am trying to get the vaapi in vlc working.

my vainfo output:

libva: VA-API version 0.32.0
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/dri/i965_drv_video.so
libva: va_openDriver() returns 0
vainfo: VA-API version: 0.32 (libva 1.0.15)
vainfo: Driver version: Intel i965 driver - 1.0.15
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            :	VAEntrypointVLD
      VAProfileMPEG2Main              :	VAEntrypointVLD
      VAProfileH264Baseline           :	VAEntrypointVLD
      VAProfileH264Baseline           :	VAEntrypointEncSlice
      VAProfileH264Main               :	VAEntrypointVLD
      VAProfileH264Main               :	VAEntrypointEncSlice
      VAProfileH264High               :	VAEntrypointVLD
      VAProfileH264High               :	VAEntrypointEncSlice
      VAProfileVC1Simple              :	VAEntrypointVLD
      VAProfileVC1Main                :	VAEntrypointVLD
      VAProfileVC1Advanced            :	VAEntrypointVLD

Video acceleration with mplayer is working fine, but with vlc is not. But i want to use vlc

When i activate the GPU acceleration in the codecs tab the video becomes very choppy an slow. It's like one frame every 2-4 seconds. Unwatchable.

I've tried different Versions from 1.1.x to 2.x and its the same every time. Don't get me wrong without vaapi the video ist smooth but my cpu usage is around 50%. I want to bring it down to save some power when i'm on battery.

Thanks for your help

Hello,

i have an i5-2500K with the HD3000, and it works just fine with an h264 movie.
My vainfo output is the same like yours....

I haven't been able to get vaapi working with VLC yet on my X220, but I have found if you use Compiz (or add a clutter environment variable if you use the Gnome 3 shell), the video output is pretty good in VLC.  I am using VLC successfully in Arch XFCE, Fedora 16 Gnome, and Mageia 1 KDE.
