Enumeration Type Documentation

enum pjmedia_transport_ice_options

Options that can be specified when creating ICE transport.

Enumerator:

PJMEDIA_ICE_NO_SRC_ADDR_CHECKING

Normally when remote doesn't use ICE, the ICE transport will continuously check the source address of incoming packets to see if it is different than the configured remote address, and switch the remote address to the source address of the packet if they are different after several packets are received. Specifying this option will disable this feature.

Function Documentation

pj_status_t pjmedia_ice_create	(	pjmedia_endpt *	endpt,
		const char *	name,
		unsigned	comp_cnt,
		const pj_ice_strans_cfg *	cfg,
		const pjmedia_ice_cb *	cb,
		pjmedia_transport **	p_tp
	)

Create the Interactive Connectivity Establishment (ICE) media transport using the specified configuration. When STUN or TURN (or both) is used, the creation operation will complete asynchronously, when STUN resolution and TURN allocation completes. When the initialization completes, the on_ice_complete() complete will be called with op parameter equal to PJ_ICE_STRANS_OP_INIT.

In addition, this transport will also notify the application about the result of ICE negotiation, also in on_ice_complete() callback. In this case the callback will be called with op parameter equal to PJ_ICE_STRANS_OP_NEGOTIATION.

Other than this, application should use the Media Transport API to manipulate this media transport.

Parameters:

	endpt	The media endpoint.
	name	Optional name to identify this ICE media transport for logging purposes.
	comp_cnt	Number of components to be created.
	cfg	Pointer to configuration settings.
	cb	Optional structure containing ICE specific callbacks.
	p_tp	Pointer to receive the media transport instance.

Returns:

PJ_SUCCESS on success, or the appropriate error code.

pj_status_t pjmedia_ice_create2	(	pjmedia_endpt *	endpt,
		const char *	name,
		unsigned	comp_cnt,
		const pj_ice_strans_cfg *	cfg,
		const pjmedia_ice_cb *	cb,
		unsigned	options,
		pjmedia_transport **	p_tp
	)

The same as with additional options param.

Parameters:

	endpt	The media endpoint.
	name	Optional name to identify this ICE media transport for logging purposes.
	comp_cnt	Number of components to be created.
	cfg	Pointer to configuration settings.
	cb	Optional structure containing ICE specific callbacks.
	options	Options, see pjmedia_transport_ice_options.
	p_tp	Pointer to receive the media transport instance.

Returns:

PJ_SUCCESS on success, or the appropriate error code.
