Media SDK on Ubuntu 16.04 failure: missing igfx_registry.txt?

 Installation follows the pattern described in this thread:https://software.intel.com/en-us/forums/intel-media-sdk/topic/691360

Outputs from all tests etc (below). look very encouraging. But running the multi_transcode example fails with error code -3. strace reveals a failure to find igfx_registry.txt? What have I missed here?

Hi,

I am not quite clear your installation process but I think that is the problem. From the error message, it seems libdrm is not the correct version, but the problem might happens all i915-i965-libdrm-libva stack, so please clarify these software components carefully.

The script was originally wrote for Ubuntu14.04, it should be ok for 16.04 but there might be little bit difference.
