Media-SDK(2017)‘s transcoder returns MFX_WRN_PARTIAL_ACCELERATION

hi,

I run the sample_multi_transcode.exe from MediaSamples_MSDK_2017_8.0.24.271\sample_multi_transcode\, and it works.

then I make DLL based on  sample_multi_transcode code and meet an error as follows:

sts = m_pmfxENC->Query(&m_mfxEncParams, &m_mfxEncParams) returns MFX_WRN_PARTIAL_ACCELERATION.

 

P.S, The Intel GPU on my laptop is HD530 and all these code runs on win10.

Whary.D

by the way, I try to transocde H265 to H264 with sample_multi_transcode.exe, it works.

my problem is what happened when I build these transcode code to DLL(I call transcode API from the DLL by a demo code) instead of EXE, and the DLLs the DLL-case load is quite different from EXE-case, which showes in VS's output window.

finaly, the reason is confliction from loading nvidia's dll before loading intel's hw dll, and this cause load un-expect dll for intel hw acceleate. just unload nvidia's project  in VS solution can handle this problem.
