Problem with second process started from not root user

I compile ffmpeg with qsv supporting (MEDIASDK 2018R1) and try run:

ffmpeg -i sintel_trailer-1080p.mp4 -vcodec h264_qsv -init_hw_device qsv:hw out_qsv.mp4 Twice and more time from root user and is works 

But when i run second process from any other user i have an error 

libva info: VA-API version 1.0.0
open lib: No such file or directory
libva info: va_getDriverName() returns 1
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_1_0
get chip id failed: -1 [13]
param: 4, val: 0
libva error: /opt/intel/mediasdk/lib64/iHD_drv_video.so init failed
libva info: va_openDriver() returns 18          

What does it mean ? How to fix ?
