Monit and Zabbix, try to restart ffmpeg script with QSV encoder

Thanks for Intel team for Media SDK. Good solution to transcode via GPU of CPU. Everything working very well.

Only one problem: when try to restart ffmpeg via monit or send remote command from ZABBIX we got error message to init MFX, if try to put command to directly to linux command line likes: node8# /etc/init.d/ch1 restart it works very well. We are tested just change in ffmpeg config file h264_qsv to libx264 we can use MONIT and Zabbix to restart.
