Enumerator
RTC_PEER_CONNECTION_STATE_NONE 

Starting state of peer connection.

RTC_PEER_CONNECTION_STATE_NEW 

This state is set when ICE Agent is waiting for remote credential.

RTC_PEER_CONNECTION_STATE_CONNECTING 

This state is set when ICE agent checks connection.

RTC_PEER_CONNECTION_STATE_CONNECTED 

This state is set when CIE Agent is ready.

RTC_PEER_CONNECTION_STATE_DISCONNECTED 

This state is set when ICE Agent is disconnected.

RTC_PEER_CONNECTION_STATE_FAILED 

This state is set when ICE Agent transitions to fail state.

RTC_PEER_CONNECTION_STATE_CLOSED 

This state leads to termination of streaming session.

RTC_PEER_CONNECTION_TOTAL_STATE_COUNT 

This state indicates maximum number of Peer connection states.

◆ RTC_RTP_TRANSCEIVER_DIRECTION

RTC_RTP_TRANSCEIVER_DIRECTION indicates direction of a transceiver.

Reference: https://www.w3.org/TR/webrtc/#dom-rtcrtptransceiverdirection

Enumerator
RTC_RTP_TRANSCEIVER_DIRECTION_SENDRECV 

This indicates that peer can send and receive data.

RTC_RTP_TRANSCEIVER_DIRECTION_SENDONLY 

This indicates that the peer can only send information.

RTC_RTP_TRANSCEIVER_DIRECTION_RECVONLY 

This indicates that the peer can only receive information.

RTC_RTP_TRANSCEIVER_DIRECTION_INACTIVE 

This indicates that the peer can not send or receive data.

◆ SDP_TYPE

enum SDP_TYPE

The enum specifies the type of SDP being exchanged

Enumerator
SDP_TYPE_OFFER 

SessionDescription is type offer.

SDP_TYPE_ANSWER 

SessionDescription is type answer.

◆ SIGNALING_API_CALL_CACHE_TYPE

Type of caching implementation to use with the signaling client.

Enumerator
SIGNALING_API_CALL_CACHE_TYPE_NONE 

No caching. The calls to the backend will be made for every API.

SIGNALING_API_CALL_CACHE_TYPE_DESCRIBE_GETENDPOINT 

Cache DeleteSignalingChannel and GetSignalingChannelEndpoint backend API calls. In this mode, the actual backend APIs will be called once and the information will be cached. This mode is the recommended mode for most of the use cases when the signaling channel is not being constantly created/deleted by other entities.

SIGNALING_API_CALL_CACHE_TYPE_FILE 

Cache DeleteSignalingChannel and GetSignalingChannelEndpoint backend API calls. In this mode, the actual backend APIs will be called once and the information will be cached into file which will allow the cache to persist next time the signaling client is created.

◆ SIGNALING_CHANNEL_ROLE_TYPE

Enumerator
SIGNALING_CHANNEL_ROLE_TYPE_UNKNOWN 

Channel role is unknown.

SIGNALING_CHANNEL_ROLE_TYPE_MASTER 

Channel role is master.

SIGNALING_CHANNEL_STATUS_ACTIVE 

Signaling channel is active.

SIGNALING_CHANNEL_STATUS_UPDATING 

Signaling channel is being updated.

SIGNALING_CHANNEL_STATUS_DELETING 

Signaling channel is being deleted.

◆ SIGNALING_CHANNEL_TYPE

Channel type as reported by the service.

Enumerator
