RTCDtlsTransport

The DTLS transport that RTP and SCTP packets go over.

class webrtc.interfaces.rtc_dtls_transport.RTCDtlsTransport(native_obj=None)

The DTLS transport that secures the packets of a webrtc.RTCPeerConnection.

The RTP and RTCP packets of its senders and receivers, and the SCTP packets of its data channels, go over it.

See MDN: RTCDtlsTransport.

Events:

• statechange (webrtc.Event) – state changed.

• error (webrtc.RTCErrorEvent) – The transport failed. The event carries the webrtc.RTCError that explains why.

Events

• statechange: Event

• error: RTCErrorEvent

Handlers are registered with on().

property ice_transport: RTCIceTransport

See MDN: RTCDtlsTransport/iceTransport.

Type:

webrtc.RTCIceTransport

property state: RTCDtlsTransportState

How far the DTLS handshake got, or whether it failed or closed.

See MDN: RTCDtlsTransport/state.

Type:

webrtc.RTCDtlsTransportState

get_remote_certificates()
