V730 Not all members of a class are initialized inside the constructor. Consider inspecting: m_associatedIRAPType, m_pocCRA, m_gdrRecoveryPointPocVal, m_HRD, m_parameterSetManager.

V1009 Check the array initialization. Only the first element is initialized explicitly. The rest elements are initialized with zeros.
