Comment (by babgvant):

 We were able to track down the issue with MFXVideoENCODE_Query. The
 documentation did not state that you must copy ExtParam before calling
 Query if they are present.

 mfxVideoParam outParam;
 MSDK_ZERO_MEMORY(outParam);
 outParam.mfx.CodecId = m_mfxEncParams.mfx.CodecId;
 if (m_mfxEncParams.NumExtParam > 0)
 {
   outParam.NumExtParam = m_mfxEncParams.NumExtParam;
   outParam.ExtParam = m_mfxEncParams.ExtParam;
 }
