according to Release Note, Intel HD driver and OpenCL SDK is included in this package, I read the different numbers of Release note about OpenCL SDK, it is very complicated to understand , which version of OS and SDK should i used for OpenCL implemention.
I tried to run the Intel Media Server sample code, it's compiled but for execution it's required the lib file :
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 error: /opt/intel/mediasdk/lib64/iHD_drv_video.so init failed
libva info: va_openDriver() returns 1
terminate called after throwing an instance of 'std::bad_alloc'

On the product details page, you can find more info about the OS and platform support.
I see you have 3rd generation system, which is not officially supported. By that I mean, any releases available publicly has not been tested on 3rd generation processor and any new feature has not been added for 3rd gen or any bug fixes will not happen on unsupported platform.This is a possible reason that you are seeing issue in running tutorial. In case, you want to give it a shot then I would recommend this -
Simple way to check if Media Server Studio is installed properly is mentioned in the 4th question "How can I check if Media Server Studio is installed correctly for my OS?" of FAQ. Please try to run pre-compiled binaries to verify installation. Also, please make sure you have booted into right kernel. From the tutorial o/p, it looks like to kernel issue.
