Function Documentation

int rtp_dynpt_encname	(	rtp_pt *	defs[],
		uint8_t	value,
		char *	enc_name
	)

Sets an encoding name for the payload type registered on the given ID

Parameters:

	defs	The payload types array where to look up the payload type.
	value	The ID for which to change the encoding name (A payload type must be already registered at the given ID)
	enc_name	The encoding name to set

Returns:

RTP_OK on succes, RTP_ERROR otherwise

Definition at line 286 of file rtp_payload_type.c.

int rtp_dynpt_set	(	rtp_pt *	defs[],
		rtp_pt *	pt,
		uint8_t	value
	)

Registers a payload type structure ad the given ID

Parameters:

	defs	The payload type array where to map the payload type to the given id
	pt	The payload type
	value	The ID mapped to the payload type (only ids > 96 are valid for dynamic payload types)

Returns:

RTP_OK on success, RTP_ERROR otherwise.

Definition at line 261 of file rtp_payload_type.c.

int rtp_pt_attr_add	(	rtp_pt *	defs[],
		uint8_t	value,
		char *	attr
	)

rtp_pt_attrs specific functions

Adds a new attribute to the given payload type ID

Parameters:

	defs	The payload types array where to look up the payload type.
	value	The ID for which to add the attribute (A payload type must be already registered at the given ID)
	attr	the name of the attribute to add

Returns:

RTP_OK on succes, RTP_ERROR if the id is out of range, -1 if failed to allocate the attribute.

Definition at line 328 of file rtp_payload_type.c.

rtp_pt* rtp_pt_new

(

rtp_media_type

mtype

)

Creates a new payload type for the given media type

Parameters:

mtype

Specifies the media type of the payload

See also:

rtp_media_type

Returns:

A new rtp payload type or NULL

Definition at line 222 of file rtp_payload_type.c.

void rtpptdefs_new

(

rtp_pt *

new_defs[]

)
