Hello, I'm a beginner of Lattepanda and trying to make the Opencv based video playback in Lattepanda (4G/64GB) using Intel graphics acceleration because video playing without Intel graphics acceleration is very slow. 

To reach the goal, I followed this reference https://software.intel.com/en-us/articl ... s-of-linux.
Although I proceed "vainfo" command to confirm whether Intel media drier is installed correctly, the result is not good like below. 
 

libva info: VA-API version 0.99.0
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 info: va_openDriver() returns 0
vainfo: VA-API version: 0.99 (libva 1.67.0.pre1)

Please teach me, How can I solve this problem? 
And then, using Intel graphics acceleration in ubuntu 16.04 is impossible? 
For reference, Ubuntu 16.04 was installed through LattePanda manual https://docs.lattepanda.com/content/1st_edition/os/
