    It modifies config files, so after running it once I edited out the parts that edit config files.

    I would modify the script with a few if statements
    The script is a derivative of this thread. Thanks though.

    What should I do to install the vaapi enabled mplayer?

    hmm... has there been any news about this new driver that uses gallium? Just wondering because they're saying that performance will shoot up... or is the driver we have it?

    So far, no idea I'm still trying but I haven't run mplayer-vaapi yet.

    A few people who built it by themselves have... but you tried that already, haven't you.

    See comment 186. No Gallium3D driver yet.

    I think I figured it out. I am now playing 720p content comfortably. I have not tried 1080p content since my only screen today is Dell Mini 12 laptop panel with 1280x800 resolution.

    Let's see if you can get it to work. I ran this sequence after switching to jolicloud kernel (comment 182). I am not convinced whether that was necessary. Update: I ran into instability with jolicloud kernel due to suspend/resume, and reverted back to Karmic kernel. Playing 720p content works fine.

    1. Add the following lines to your /etc/apt/sources.list
      Code:
      ## Repository for fit-PC2 users provided by Compulab
      deb http://fit-pc2.com/download/ubuntu/dists/karmic binary/
      deb-src http://fit-pc2.com/download/ubuntu/dists/karmic source/
    2. Refresh update manager
      Code:
      sudo apt-get update
    3. Uninstall mplayer provided by Karmic
      Code:
      sudo apt-get remove mplayer-nogui
      sudo apt-get remove mplayer
    4. Install mplayer with vaapi support
      Code:
      sudo apt-get install libva1 mplayer-vaapi mplayer-skins
    5. Comment out fit-pc repository by editing /etc/apt/sources.list
      Code:
      ## Repository for fit-PC2 users provided by Compulab
      #deb http://fit-pc2.com/download/ubuntu/dists/karmic binary/
      #deb-src http://fit-pc2.com/download/ubuntu/dists/karmic source/
    6. Link the va driver from Poulsbo driver
      Code:
      sudo ln -s /usr/X11R6/lib/modules/dri/psb_drv_video.so /usr/lib/va/drivers
    7. Run vainfo and make sure you get no errors

      Code:
      $ vainfo
      libva: libva version 0.31.0-sds4
      libva: va_getDriverName() returns 0
      libva: Trying to open /usr/lib/va/drivers/psb_drv_video.so
      libva: va_openDriver() returns 0
      vainfo: VA API version: 0.31
      vainfo: Driver version: Intel GMA500 - 5.0.1.0046
      vainfo: Supported profile and entrypoints
            VAProfileMPEG2Main              :	VAEntrypointVLD
            VAProfileMPEG2Main              :	VAEntrypointMoComp
            VAProfileMPEG4Simple            :	VAEntrypointVLD
            VAProfileMPEG4AdvancedSimple    :	VAEntrypointVLD
            VAProfileH264Baseline           :	VAEntrypointVLD
            VAProfileH264Main               :	VAEntrypointVLD
            VAProfileH264High               :	VAEntrypointVLD
            VAProfileVC1Simple              :	VAEntrypointVLD
            VAProfileVC1Main                :	VAEntrypointVLD
            VAProfileVC1Advanced            :	VAEntrypointVLD
    8. Test mplayer on any MPEG4 or H264 content
      Code:
      mplayer -va vaapi -vo vaapi -ao oss HDvideo.mp4
      Note: I had problems with sync between video and audio, so I specified audio output by adding -ao oss option.
      Alternative options for -ao (audio output) are -ao pulse, -ao sdl and -ao alsa.

    mplayer -vo vaapi -ao pulse filename.mp4

    Players that ship with 9.04 or 9.10 cannot use video acceleration by poulsbo. You need mplayer-vaapi package. Either build it yourself, or install a build using instructions in comment 196.

    Note that in either case you need to provide special video acceleration API (VAAPI) libraries and ensure they work fine.

    Update: you need at least version 0.31 of the VAAPI library. Installations in the OP refers to ubuntu-mobile of library version 0.29 which is too old.
