Variable QWBPEncoderConst

Type declaration

• encode: ((fingerprint: Uint8Array, candidates: QWBPCandidate[]) => Uint8Array)

  • • (fingerprint, candidates): Uint8Array

    • Encodes a QWBP packet

      Parameters

      • fingerprint: Uint8Array

        32-byte DTLS fingerprint
      • candidates: QWBPCandidate[]

        Array of ICE candidates to encode

      Returns Uint8Array

      Encoded binary packet

      Throws

      QWBPEncodeError if fingerprint is not 32 bytes or IP addresses are invalid

      Example

      const packet = QWBPEncoder.encode(fingerprint, [
        { ip: '192.168.1.5', port: 54321, type: 'host', protocol: 'udp' },
        { ip: '203.0.113.50', port: 54322, type: 'srflx', protocol: 'udp' },
      ]);
      Copy

• extractCandidatesFromSDP: ((sdp: string, maxCandidates?: number) => QWBPCandidate[])

  • • (sdp, maxCandidates?): QWBPCandidate[]

    • Extracts and encodes candidates from SDP

      Uses smart selection to ensure NAT traversal capability:

      • Always includes at least one srflx candidate if available
      • Fills remaining slots with host candidates (prioritizing IPv4)

      Parameters

      • sdp: string

        SDP string containing candidate lines
      • maxCandidates: number = 4

        Maximum number of candidates to extract (default: 4)

      Returns QWBPCandidate[]

      Array of QWBP candidates
