HI, Guys
Could you help check why I can not playback MPEG2 with VAAPI at G45 ? 

Thanks for advance!

Stephen 

 

Steps:

1. Prepare a new ubuntu9.04 for Intel G45. 

2. Download the latest libva (libva-latest.tar.gz ) from http://www.splitted-desktop.com/‾gbeauchesne/libva/. 

3. The tarball contains the upstream libva sources. Patches are in the debian/patches directory. Patch it. 

$ dpkg-buildpackage -rfakeroot -uc -us

4. $  ./configure -prefix=/usr  --enable-i965-driver 

5. $  make && make install              

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;

            2) It will create and install i965_drv_video.so into /usr/lib/va/drivers/

6. Download the latest mplayer-vaapi package from http://www.splitted-desktop.com/‾gbeauchesne/mplayer-vaapi/, 

7. Make sure you also have `svn' (subversion) and all necessary MPlayer libraries. 

$ apt-get install subversion

$ apt-get build-dep mplayer

8. unpack mplayer tarball and run the supplied script to build mplayer-vaapi 

   $ ./Checkout-patch-build.sh

9. Copy the “mplayer” executable program into /usr/local/bin or /usr/bin. 

10. Made the requirement environment variable. 

$ export LIBVA_DRIVERS_PATH=/usr/lib/va/drivers/

 

11. Running MPlayer with vaapi. 

$ mplayer -vo vaapi <URI>

                        Result: can’t play video by vaapi yet. FYI attached logs.

MPlayer interrupted by signal 6 in module: uninit_vo

- MPlayer crashed. This shouldn't happen.

  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your

  gcc version. If you think it's MPlayer's fault, please read

  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and

  won't help unless you provide this information when reporting a possible bug.
