Detailed Description

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

---

Define 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
