Is your non-root user a member of the video group?  That could explain why sudo/root makes a difference.

Also, for Generic installs (as for Ubuntu) you must set two environment variables:

LIBVA_DRIVERS_PATH=/opt/intel/mediasdk/lib64
LIBVA_DRIVER_NAME=iHD

hi Jeffrey Mcallister super-man

   Thanks for your response ~

Q1. Is your non-root user a member of the video group?  That could explain why sudo/root makes a difference.    

> from the following, I know I got the same right as video ~

[_build] $ whoami
dspuser
[_build] $ groups
dspuser adm cdrom sudo dip video plugdev lpadmin sambashare 

Q2. Also, for Generic installs (as for Ubuntu) you must set two environment variables:

       LIBVA_DRIVERS_PATH=/opt/intel/mediasdk/lib64
       LIBVA_DRIVER_NAME=iHD
