RTCPeerConnection
Talk WebRTC from Delphi/C++Builder — ICE for connectivity, DTLS 1.3 for the keying handshake, SRTP for media, SCTP-over-DTLS for DataChannels. No browser required.

Native Delphi WebRTC peer — mirrors the W3C RTCPeerConnection surface (CreateOffer / CreateAnswer / SetRemoteDescription / AddIceCandidate / DataChannel) backed by the bundled ICE, DTLS 1.3, SRTP and SCTP stacks.

Add ICE servers, CreateOffer, send the SDP to the remote peer over your signalling channel, set the answer, and the data path lights up.

Peer->CreateOffer();A native WebRTC peer that bundles ICE, DTLS 1.3, SRTP and SCTP into a single component — mirroring the W3C RTCPeerConnection API.
CreateOffer and CreateAnswer generate RFC 8866 SDP with the right ICE-UFRAG / ICE-PWD / FINGERPRINT / SETUP attributes; SetRemoteDescription ingests the peer's SDP.
Uses TsgcICEClient internally for candidate gathering and connectivity checks; AddIceCandidate feeds remote candidates as they trickle in from signalling.
After the selected ICE pair becomes writable, the component performs a DTLS 1.3 handshake (RFC 9147) and derives SRTP keys via SRTP-extractor.
CreateDataChannel opens an SCTP stream multiplexed over DTLS — reliable / partial-reliable, ordered / unordered, with backpressure via BufferedAmount.
Audio / video tracks travel over SRTP. The companion TsgcWSPServer_RTCPeerConnection server-side signalling component lets you build SFU-style relays.
Interops with browser RTCPeerConnection — tested against Chromium / Firefox / Safari. Same SDP semantics, same ICE candidates, same DataChannel wire format.
