I am trying to install the Intel MSS 2017 on my Centos 7.2.1511
When I type the command: "cat lspci -nn -s 0:02.0" this is the output:
00:02.0 VGA compatible controller [0300]: Intel Corporation Sky Lake Integrated Graphics [8086:1916] (rev 07)
meaning I have the appropriate hardware to run it, but after I finished running the installation scripts, I tried to check whether the installation went correctly, so I typed the command vainfo and got this in return:
libva info: VA-API version 0.39.3
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'
libva info: Trying to open /opt/intel/mediasdk/lib64/iHD_drv_video.so
libva info: Found init function __vaDriverInit_0_32
Segmentation fault (core dumped)
this is the ouptut of running gdb vainfo:
Reading symbols from /usr/local/bin/vainfo...done.
(gdb) run

Any help would be much appreciated. Thanks!

hi yair.s
I use libva directly ,and i use libva-intel-driver , so when I use "vainfo", it open i965_drv_video.so , it's correct.
iHD_drv_video is a closed source,and libva-intel-driver is open source, do you know the diffience between these two driver??
Best regard

Hi yair.s
This looks like an installation error, from your error message, I can see iHD driver is called correctly from libVA so it might caused by KMD installation error, for the closed i915 driver, we do a kernel patch in the installation process. unfortunately our script doesn't show error message in a good way. If you go back to check the process when it does the kernel patch.
To gy, although both drivers uses hardware QSV functions, the difference is: the "closed driver"(i915) has the original/strong support from Intel graphic driver team. And you are partly wrong about "closed driver", it is open source now. You can find it in following URL:
https://github.com/Intel/media-driver
We also have an open source media project and you can build whole media stack based on following instructions:
https://software.intel.com/en-us/articles/build-and-debug-open-source-media-stack
I am not going to discuss more about the driver issue since this is yair's issue, please open a new post if you want to continue the discussion.
