To: <a href="mailto:libva@lists.freedesktop.org">libva@lists.freedesktop.org</a> <o:p></o:p> HI, Guys Could you help check why I can not playback MPEG2 with VAAPI at G45 ? <o:p></o:p> Thanks for advance!<o:p></o:p> Stephen <o:p></o:p>  <o:p></o:p> Steps:<o:p></o:p> 1. Prepare a new ubuntu9.04 for Intel G45. <o:p></o:p> 2. Download the latest libva (libva-latest.tar.gz ) from <a href="http://www.splitted-desktop.com/~gbeauchesne/libva/" target="_blank">http://www.splitted-desktop.com/~gbeauchesne/libva/</a>. <o:p></o:p> 3. The tarball contains the upstream libva sources. Patches are in the debian/patches directory. Patch it. <o:p></o:p> $ dpkg-buildpackage -rfakeroot -uc -us<o:p></o:p> 4. $  ./configure –prefix=/usr  --enable-i965-driver <o:p></o:p> 5. $  make && make install              <o:p></o:p> Result: 1) It will create and install libva-0.31.0.3.so.1.0.0 into /usr/lib/ and make the /usr/lib/libva.so -> libva-0.31.0.3.so.1.0.0 link;<o:p></o:p>             2) It will create and install i965_drv_video.so into /usr/lib/va/drivers/<o:p></o:p> 6. Download the latest mplayer-vaapi package from <a href="http://www.splitted-desktop.com/~gbeauchesne/mplayer-vaapi/" target="_blank">http://www.splitted-desktop.com/~gbeauchesne/mplayer-vaapi/</a>, <o:p></o:p> 7. Make sure you also have `svn' (subversion) and all necessary MPlayer libraries. <o:p></o:p> $ apt-get install subversion<o:p></o:p> $ apt-get build-dep mplayer<o:p></o:p> 8. unpack mplayer tarball and run the supplied script to build mplayer-vaapi <o:p></o:p>    $ ./Checkout-patch-build.sh<o:p></o:p> 9. Copy the “mplayer” executable program into /usr/local/bin or /usr/bin. <o:p></o:p> 10. Made the requirement environment variable. <o:p></o:p> $ export LIBVA_DRIVERS_PATH=/usr/lib/va/drivers/<o:p></o:p>  <o:p></o:p> 11. Running MPlayer with vaapi. <o:p></o:p> $ mplayer –vo vaapi <URI><o:p></o:p>                         Result: can’t play video by vaapi yet.
