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;
}
