Hi WSM,

From python script report, looks like your hardware and OS is OK and I assume you have run the installation successfully. Did you set following environment variables when running "vainfo"?

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

If this still doesn't work, you can also double check the detailed installation steps with the following document:

https://software.intel.com/sites/default/files/managed/52/a7/media_server_studio_getting_started_guide.pdf

Did you run it manually or with script? The script goes very fast and you might miss some error messages.
