DecodePrgCfgElt

Gets program configuration element from the input bitstream.

Syntax

IppStatus ippsDecodePrgCfgElt_AAC(Ipp8u** ppBitStream, int* pOffset, IppAACPrgCfgElt* pPrgCfgElt);

Parameters

ppBitStream	Double pointer to the current byte after decoding the program configuration element.
pOffset	Pointer to the bit position in the byte pointed to by ppBitStream. Valid within 0 to 7:
	0 stands for the most significant bit of the byte; 7 stands for the least significant bit of the byte.
pPrgCfgElt	Pointer to IppAACPrgCfgElt structure.

Description

This function is declared in the ippac.h file. The function gets the program configuration element from the input bitstream. See clause 8.5 and Table 6.21 of ISO/IEC 13818 - 7: 1997.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when at least one of the pointers ppBitStream, pOffset, pPrgCfgElt, or ppBitStream is NULL.
ippStsAacBitOffsetErr	Indicates an error when pOffset is out of the range of [0,7].
