This member function sets m_trLateto the value of trLateand m_trFrameto the value of trFrame.
When the CBaseVideoRenderer::RecordFrameLatenessmember function is called from either CBaseVideoRenderer::OnRenderStartor CBaseVideoRenderer::OnDirectRender, it passes the values of m_trLateand m_trFramefor it to update the statistics. PreparePerformanceDatais called from CBaseVideoRenderer::OnWaitEndto set these data member values.
