Functions
void	asn1_decodeActions (fpa1_syntaxList *listPtr, MHEG5ActionList *p_actions)
	Decodes action class Refer to MHEG5 Specification (ISO/IEC 13522-2:1996), Appendix A, section [A.42] for details of ASN.1 representation. This function ignores any elementary actions in cannot decode (Including if a malloc fails during decoding. NULL is returned if no actions could be decoded. More...

	Refer to MHEG5 Specification (ISO/IEC 13522-2:1996), Appendix A, section[A.3] for details of ASN.1 representation. NextScenes is a GList containg references to the following scenes. Each reference are of the form: OpenBracket, OctetString, Integer, CloseBracket. Safe if asn1_addGList() fails to allocate memory, returns NULL after deleting any allocated GList items. More...

Function Documentation

void asn1_decodeActions	(	fpa1_syntaxList *	listPtr,
		MHEG5ActionList *	p_actions
	)

Decodes action class Refer to MHEG5 Specification (ISO/IEC 13522-2:1996), Appendix A, section [A.42] for details of ASN.1 representation. This function ignores any elementary actions in cannot decode (Including if a malloc fails during decoding. NULL is returned if no actions could be decoded.

Parameters

listPtr	pointer to current fpa1_syntaxList item
p_actions	pointer to MHEG5ActionList

Returns

void

Parameters

listPtr

pointer to current fpa1_syntaxList item

Returns

MHEG5Action. NULL if fails.

void asn1_decodeNextScenes	(	fpa1_syntaxList *	listPtr,
		ParamList *	p_scenes
	)

Refer to MHEG5 Specification (ISO/IEC 13522-2:1996), Appendix A, section[A.3] for details of ASN.1 representation. NextScenes is a GList containg references to the following scenes. Each reference are of the form: OpenBracket, OctetString, Integer, CloseBracket. Safe if asn1_addGList() fails to allocate memory, returns NULL after deleting any allocated GList items.

Parameters

listPtr	pointer to current fpa1_syntaxList item
p_scenes	Pointer to next scenes list being decoded.

Returns

void
