unable to use hardware acceleration (-hw) for sample decode in LINUX

[hasbullah_p_]

Hi There,

we are running the sample decode (example code provided by intel in intel media server studio essential 2017 R1 running in centOS 7.2.1511 kernel version 3.10.0-514.6.1.el7.x86_64). We are able to run the code with software (-sw) mode but error occur when we use hardware (-hw). the error are as follows:

[centos@localhost release]$ sudo ./sample_decode h264 -hw -i /home/centos/Videos/Simpsons.h264 -r
