why HW 1.7 not support in result mediasdk_sys_analyzer?
The HW acceleration path is accessed via the Media SDK DLL which is part of Intel graphics driver. A graphics driver with support for API1.7 has not yet been released, but you should expect to see it appear on https://downloadcenter.intel.com/default.aspx very soon.
MSI support published a driver with API 1.7.
Thanks Michael ! it works well .
