Function Documentation

MHEG5Bool MHEG5parseDvbUrl	(	U8BIT *	buffer,
		U32BIT	length,
		S_DVB_LOCATOR *	dvb_loc
	)

Parse a DAVIC style multiplex reference or UK-DTT inherritance format URL. This can be one of the following forms: rec://svc/cur rec://svc/def rec://svc/lcn/# dvb://original_network_id.[transport_stream_id].service_id[.*].

Parameters

buffer	Pointer to character buffer containing the URL string
length	Length of character buffer
multiplexRef	Multiplex reference extracted from the URL string

Returns

MHEG5TRUE if URL could be decoded, else MHEG5FALSE

MHEG5Bool MHEG5parseEncodeQPrintable	(	MHEG5Byte **	buffer,
		MHEG5Int *	used,
		MHEG5Int *	allocated,
		MHEG5Generic *	value
	)

Add a value to the buffer. The value is QPrintable-encoded, which means that printable characters are copied without change, and non-printable characters (along with '=' and ''') are encoded using the equal sign and two hexadecimal digits characters which hold the numerical representation of the character in ASCII. For example, a carriage-return character is encoded as '=0D'.

Parameters

buffer	Buffer to add the value to
used	Number of characters used in the buffer
allocated	Number of characters allocated for the buffer
value	The value to append

Returns

MHEG5TRUE if the value was added, MHEG5FALSE otherwise

int MHEG5parseLcn	(	U8BIT *	buf,
		U8BIT *	end
	)
