[Libva] vainfo segfault on GM965

[Nicholas Andrade]

Hi Yakui,
Thanks for the info & the patch.  The patch worked in that it got rid of the segfault and returned the previous error:<<<<<libva info: VA-API version 0.36.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /home/neandrad/libva-intel-driver-1.4.1/src/.libs/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_36
libva error: /home/neandrad/libva-intel-driver-1.4.1/src/.libs/i965_drv_video.so init failed
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
>>>>>I did experience bug 79478 when complining, however I applied the workaround in common 6 to get past it.

Just so I'm clear, does the GM965 have any va-api/libva support?  If so, which driver supports the GM965?  Did any previous version of libva support it?  I don't mind using an unstable or deprecated branch for my use case.
Also, on a side note, I have an Ivy Bridge system where libva works very well.

Thanks,Nick
