const char *  load_plugins 

Initialize a MSDK session.

Media SDK is based on sessions, so this is the prerequisite initialization for HW acceleration. For Windows the session is complete and ready to use, for Linux a display handle is required. For releases of Media Server Studio >= 2015 R4 the render nodes interface is preferred (/dev/dri/renderD). Using Media Server Studio 2015 R4 or newer is recommended but the older /dev/dri/card interface is also searched for broader compatibility.
