i965_drv_video.so not found on CentOS 7.1

Hi there,

We tried to switch our development from SLES11 / MSS R3 to CentOS 7.1 / MSS R6. While I am setting up CentOS 7.1, I found that the MSDK won't run. libva is looking for /usr/lib64/dri/i965_drv_video.so which is not found on the system. 
I workaround the issue by soft-link i965_drv_video.so to iHD_drv_video.so. Then, everything works!

Two questions:
1) Do you see any problem of pointing the drive to iHD_drv_video.so?
2) Why would libva look for i965_drv_video.so? Am I missing some components during the installation?

Here is my system information:
OS: CentOS 7.1
Kernel: 3.10.0-229.1.2.39163.MSSr4.el7.centos.x86_64
MSDK: Media Server Studio Essentials 2015 R6
CPU: Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz

Thanks,
Ken

Hi Ken, 

i965 is not an Intel driver, the reason of the failure while running samples possibly could be the  permissions, you might not be added as a video group which is a requisite mentioned in the install. 
Is this the error you are seeing, when running samples?
 libva error: va_getDriverName() failed with operation failed,driver_name=i965
terminate called after throwing an instance of 'std::invalid_argument'
  what():  Loading of VA display was failed
Aborted (core dumped)

If you add the user to media group the o/p will look like - 
libva info: VA-API version 0.35.0
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
libva info: va_openDriver() returns 0
Decoding Sample Version 6.0.16043175.175

 

n case, you are set up a usergroup and still see the issue, then please copy the complete failure you see. We will look into it. 

Thanks,
Surbhi

Hi Surbhi,

You are right. I added myself to video group and the sample code is loading iHD_* driver.

Thank you!
Ken

Great! Closing this thread, please start a new topic if you have any Media Server Studio/Media SDK related question. 

Thanks,
