Media SDK LINK error in multi_transcode

I followed the instructions and built the Media SDK samples. I succeeded in compiling the encode and decode samples, but failed in the transcoding one.

I just could't get rid of the LNK 2019 error:

2>pipeline_transcode.obj : error LNK2019: unresolved external symbol "public: __cdecl MFXVideoVPPPlugin::MFXVideoVPPPlugin(struct _mfxSession *)" (??0MFXVideoVPPPlugin@@QEAA@PEAU_mfxSession@@@Z) referenced in function "protected: virtual enum mfxStatus __cdecl TranscodingSample::CTranscodingPipeline::VPPPreInit(struct TranscodingSample::sInputParams *)" (?VPPPreInit@CTranscodingPipeline@TranscodingSample@@MEAA?AW4mfxStatus@@PEAUsInputParams@2@@Z)
2>..\_build\x64\Debug\sample_multi_transcode.exe : fatal error LNK1120: 1 unresolved externals

Any idea what the problem should be?

BTW, I used Visual Studio 2012 under Window 7 x64.

Regards,

Zheng

Hi Zheng,

Are you seeing this link error using unmodified sample code?  I do not see any issues.  Perhaps it is worth obtaining a clean install of just released Media SDK 2014 and try again.

Is your Visual Studio using the latest updates from Microsoft?

I'm unaware of any of these being an issue.
