Installing problem on centos 7.1


I have fresh new install of centos 7.1 and trying to install intel media server studio essential 2015 r5.

I follow the steps described in getting started guide., but after install_sdk_umd... finishes installing packages from yum repo and starts installing sdk provided rpm files, I am getting error: mesa-dri-drivers >= 8.0.1 is needed by libva-1.3.1-staging.20130628.36242.el7.x86_64.

I installed that package from yum repo and re-started install_sdk_umd... after installation have finished, I started finished ok, I installed newly builded kernel to the system and re-started the system.

Checked if the system is running using the provided kernel and if the module is loaded correctly:

[root@localhost ~]# uname -a
Linux localhost.localdomain 3.10.0- #1 SMP Tue May 12 21:14:39 GET 2015 x86_64 x86_64 x86_64 GNU/Linux

anyone can tell me why I am getting <unknown entrypoint> in vainfo output?


Hi Zurab, 

This is not expected, we are looking into this issue. Can you please confirm if the problem exist after re-installing all of the RPMs with --force + reboot as mentioned in getting started guide?  
Also, try to run sample application and check if they run smoothly. Let us know the result. 



HI Zurab, 

After discussing this issue with experts, these <unknown encrypt> msgs is not an installation issue. You shouldn't see any problem with any codec.  These msgs means that media sdk are limitations of media stack/vainfo tool & is not exposing to those entrpoints 

Hope that answer your question.



Hi Zurab,

I am wondering whether you are able to install CentOS 7.1 and the OpenCL runtime through Intel media server studio essential 2015 r5 successfully. If yes, could I ask you for suggestions to resolve the installation issue I am facing? 

I am not able to install the newly built kernel. In particular, I am following these steps (most of the steps are based on the official instructions from Intel).

Installed CenOS 7.1 using an ISO from: . I chose "Development and Creative Workstation" base environment and  "development tools" add-on  during the OS installation. I think it should be the right version of the OS but, still could you tell me the base kernel-version of the CentOS that you installed?

- Installed packages by running : it seems to have installed everything fine.

-  Built kernel using : it took more than an hour and finished with a message- "+exit 0       /MSS      INFO... Please find kernel rpm under ./rpmbuild/RPMS folder." I feel that this step is also fine, but I not 100% sure. Please let me know if this message denotes a successful build or not.

- Installing the kernel: this step seems to be the issue because the OS crashes when I reboot the system the system after this step. Actually, this step finished in less than 1 minute for me with the following message. Could you comment on this?

Before rebooting when I run uname -r command, I see 3.10.0-229.el7.x86_64 version. 

Any help or pointer is greatly appreciated.

Thanks and Regards,
