SpeexHeader: Makes it easy to write/parse an Ogg/Speex header

Classes
struct	SpeexHeader

Macros
#define	SPEEX_HEADER_STRING_LENGTH   8
#define	SPEEX_HEADER_VERSION_LENGTH   20

Typedefs
typedef struct SpeexHeader	SpeexHeader

Functions
void	speex_init_header (SpeexHeader *header, int rate, int nb_channels, const struct SpeexMode *m)
char *	speex_header_to_packet (SpeexHeader *header, int *size)
SpeexHeader *	speex_packet_to_header (char *packet, int size)
void	speex_header_free (void *ptr)

Detailed Description

This is the Speex header for the Ogg encapsulation. You don't need that if you just use RTP.

Macro Definition Documentation

#define SPEEX_HEADER_STRING_LENGTH   8

Length of the Speex header identifier

#define SPEEX_HEADER_VERSION_LENGTH   20

Maximum number of characters for encoding the Speex version number in the header

Typedef Documentation

typedef struct SpeexHeader SpeexHeader

Speex header info for file-based formats

Function Documentation

void speex_header_free

(

void *

ptr

)

Frees the memory allocated by either speex_header_to_packet() or speex_packet_to_header()

char* speex_header_to_packet	(	SpeexHeader *	header,
		int *	size
	)

Creates the header packet from the header itself (mostly involves endianness conversion)

void speex_init_header	(	SpeexHeader *	header,
		int	rate,
		int	nb_channels,
		const struct SpeexMode *	m
	)

Initializes a SpeexHeader using basic information

SpeexHeader* speex_packet_to_header	(	char *	packet,
		int	size
	)

Creates a SpeexHeader from a packet
