Breaking change : MFXVideoUSER_Register = MFX_ERR_UNSUPPORTED with Gen12 / 13 CPU

We have a working application based on Intel Media SDK / OpenCL plugin, and it works on all Intel CPU's  <= Generation 11.

We notice that libmfxhw64.dll is loaded in the working situation. (<= Gen 11 )

And libmfx64-gen.dll in the not working situation (Gen 12, Gen 13)

MFXVideoUSER_Register returns MFX_ERR_UNSUPPORTED, and PluginInit is not called at all.

 

Is there an easy way to force loading the libmfxhw64.dll ?

since libmfx64-gen.dll is not working for us.

 

Best regards,

Robert

Hi,


Thank you for posting in Intel Communities. We apologize to inform you that the Official Intel MediaSDK specifications document(https://www.intel.com/content/www/us/en/developer/tools/media-sdk/overview.html) specifies that the MediaSDK supports processors only upto 11th generation Intel® Core™ processors. Please try the same in one of the supported processors and let us know if the issue still persists.


If this clarifies your issue, make sure to accept this as a solution. This helps others with similar errors.


Thanks,

Alekhya
