GstBaseSignalerClass

This module handles the signaling mechanism to negotiate.

Methods

• connect(GstBaseSignaler * self): Connect to signaling server.
• disconnect(GstBaseSignaler * self): Disconnect from signaling server.
• is_connect(GstBaseSignaler * self): Check whether there is a connection to signaling server.
• send_local_description(GstBaseSignaler * self, gchar * description, GstWebRTCSDPType type): Send the local description through signaling.
• send_candidate(GstBaseSignaler * self, const gchar * mid, gint sdpmlineindex, gchar * candidate): Send the candidate through signaling.

Signals

• connected: Emitted when a peer is connected to the same session.
• disconnected: Emitted when the peer is disconnected from the session.
• add-remote-description: Emitted when a description arrives.
• add-candidate: Emitted when a candidate arrives.
• signaler-notify: Emitted when any notification needs to be sent to the bus.
• error-connection: Emitted when the signaler has an error in one of the methods.

Detailed methods

connect

connect(GstBaseSignaler * self)

Parameters

Returns

True if connection was successful.

is_connect

is_connect(GstBaseSignaler * self)

Parameters

self: The concrete signaler

Returns

True if the signaler is connected.

disconnect

disconnect(GstBaseSignaler * self)

Parameters

self: The concrete signaler.

Returns

Parameters

self: The concrete signaler.

description: The local description SDP to send.

type: SDP type offer/answer.

Returns

gboolean -> True or False if sending operation was successful.

send_candidate
