Bool TDecTop::isRandomAccessSkipPicture	(	Int &	iSkipFrame,
		Int &	iPOCLastDisplay
	)

private

Function for checking if picture should be skipped because of random access

Parameters

iSkipFrame	skip frame counter
iPOCLastDisplay	POC of last picture displayed

Returns: true if the picture shold be skipped in the random access. This function checks the skipping of pictures in the case of -s option random access. All pictures prior to the random access point indicated by the counter iSkipFrame are skipped. It also checks the type of Nal unit type at the random access point. If the random access point is CRA/CRANT/BLA/BLANT, TFD pictures with POC less than the POC of the random access point are skipped. If the random access point is IDR all pictures after the random access point are decoded. If the random access point is none of the above, a warning is issues, and decoding of pictures with POC equal to or greater than the random access point POC is attempted. For non IDR/CRA/BLA random access point there is no guarantee that the decoder will not crash.

Bool TDecTop::isSkipPictureForBLA ( Int & iPOCLastDisplay )

private

Function for checking if picture should be skipped because of association with a previous BLA picture

Parameters

iPOCLastDisplay POC of last picture displayed

Returns: true if the picture should be skipped This function skips all TFD pictures that follow a BLA picture in decoding order and precede it in output order.
