My system is Core i3 2100 and it's sandbridge supported. ButQueryIMPL said it dosen't support hardware encoding.
Can you help me what problem?
Make sure you have the latest Intel graphics driver installed. If your system has a discrete graphics card, also make sure that the Intel graphics device is selected as primary device (the sample code depends on this to access HW acceleration).
It may also help to run the Media SDK tool, mediasdk_sys_analyzer, part of the SDK package, to help determine what may be wrong with your system configuration.Regards,Petter
Thanks response so fast.
I and mediasdk_sys_analyzerin a Core i72600 PC which have same problem.
The PC only haveonboard Intel HD2000 video card andI just installed lastest driver.
nothelpful. Please see followed output infomation ofmediasdk_sys_analyzer.

By mediasdk_sys_analyzer report:
why dose SDK version 1.1 support hardwareencoding but 1.3 dosen't support?
Looking at the sys_analyzer output your issue is likely related to the API version you are initializing your session with.
Media SDK 2012 does support API version 1.3 if using the SW implementation. The Media SDK HW implementation (acceleration) is delivered with the Intel Graphics driver, not with the SDK.There is a new graphics driver (126.96.36.19956) available here:http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Graphics&ProductLine=Processor+graphics&ProductProduct=2nd+Generation+Intel%C2%AE+Core%E2%84%A2+Processors+with+Intel%C2%AE+HD+Graphics+3000%2f2000&ProdId=3319&LineId=3310&FamilyId=39that do support API 1.3 for current generation Core processors. A driver the 3rd generation Core processors will be available soon (effectively making API 1.3 available for those platforms too).
BTW. If you do not need the latest set of Media SDK features you can still use API version 1.1.
