1335	NoOutputOfPriorPicsFlag can be mishandled by reference decoder	jackh		"TDecTop::checkNoOutputPriorPics(), called following an IRAP picture for which NoOutputOfPriorPicsFlag==1 (call this picture A), unsets the output flag on all pictures except pictures whose POC is the same as picture A (this value is held in m_lastPOCNoOutputPriorPics). 

This can cause pictures to be output in error if a picture held in the DPB from the previous IRAP has the same POC as picture A. In this case the picture will not have its output flag unset and may be output later.

There is no need for this POC check as picture A will not yet have been added to the DPB when checkNoOutputPriorPics() is called, so there is no danger of incorrectly setting its output flag. I therefore suggest that this condition be removed from checkNoOutputPriorPics(). Since the variable m_lastPOCNoOutputPriorPics no longer has any purpose once this check is removed, the variable can also be removed."	defect	new	minor		HM	HM-16.1			ksuehring davidf karlsharman jct-vc@…
