TelegramMessenger/tgcalls/experimental • b0245de • 3 files, +533/-17 feat: add video support to group calls (CustomImpl + ReferenceImpl) Enable H264 simulcast video in group calls for both GroupInstanceCustomImpl and GroupInstanceReferenceImpl, with reactive channel setup mirroring the real Telegram app's flow. Infrastructure: - DiscardPacketsWithUnknownSsrc field trial prevents outgoing video channel from stealing incoming RTP for unregistered SSRCs - dataChannelMessageReceived callback on GroupInstanceDescriptor forwards Colibri messages (ActiveVideoSsrcs) to the application layer ReferenceImpl video implementation: - Pre-allocate 6 video SSRCs (3 layers x primary + RTX) at construction - SDP munging: replace PeerConnection's auto-generated StreamParams with pre-allocated SSRCs + SIM + FID groups before SetLocalDescription - Video source activated via sender()->SetTrack() (no renegotiation) - Incoming video: recvonly transceivers with explicit remote SSRCs in answer (required because DiscardPacketsWithUnknownSsrc is process-wide) - Video sinks wired explicitly after SetRemoteDescription (OnTrack doesn't fire for locally-created recvonly transceivers) - Colibri ReceiverVideoConstraints sent over data channel to control SFU forwarding; SFU responds with SenderVideoConstraints + proactive PLI Squashed from: - feat: enable DiscardPacketsWithUnknownSsrc field trial for video group calls - feat: add dataChannelMessageReceived callback to GroupInstanceDescriptor - feat(group-ref): store video configuration from descriptor - feat(group-ref): pre-allocate video SSRCs and include in join payload - feat(group-ref): add video encoder/decoder factories to PeerConnectionFactory - feat(group-ref): implement setVideoSource with SDP munging for simulcast SSRCs - feat(group-ref): extend buildRemoteAnswer with video m-line construction - feat(group-ref): forward data channel messages to app for video signaling - feat(group-ref): implement setRequestedVideoChannels with Colibri constraints - feat(group-ref): implement addIncomingVideoOutput with video sink wiring - fix(group-ref): activate outgoing video after join response is applied - feat(group-ref): add video support to GroupInstanceReferenceImpl #tgcalls

TelegramMessenger/tgcalls/experimental • eb2bd7d • 7 files, +2173/-155 feat: add InstanceV2CompatImpl for cross-version interop (v14.0.0) New implementation that uses WebRTC PeerConnection internally but speaks V2Impl's signaling protocol (InitialSetupMessage, NegotiateChannelsMessage, CandidatesMessage). Enables bidirectional calls between PeerConnection-based clients and V2Impl clients (versions 7.0.0-13.0.0). Architecture: PeerConnection <-> SignalingTranslator <-> EncryptedConnection <-> SignalingSctpConnection Key components: - SignalingTranslator: converts between cricket::SessionDescription and V2Impl signaling messages using JsepSessionDescription programmatic API (no SDP string round-trips) - Shared conversion functions extracted to Signaling.h/.cpp for use by both ContentNegotiationContext (V2Impl) and SignalingTranslator (CompatImpl) - Data channel works for CompatImpl<->CompatImpl calls; padded as rejected when paired with V2Impl (which has no PeerConnection) 100% success rate at 30% loss in both call directions. Squashed from: - refactor: extract signaling content conversion functions to Signaling.h/.cpp - feat: add SignalingTranslator for V2Impl signaling <-> PeerConnection conversion - feat: add InstanceV2CompatImpl — PeerConnection with V2Impl signaling (version 14.0.0) - feat: add data channel support to InstanceV2CompatImpl TelegramMessenger/tgcalls/experimental • 08cd6d5 • 2 files, +1110/-0 feat: add GroupInstanceReferenceImpl — PeerConnection-based group calls Alternative group call implementation using standard WebRTC PeerConnection instead of the manual ICE/DTLS/SRTP management in GroupInstanceCustomImpl. Implements the same GroupInstanceInterface (~1500 lines vs ~4700). Uses a single PeerConnection to the SFU with: - sendrecv audio transceiver (outgoing audio) - recvonly audio transceivers added dynamically per remote SSRC - data channel for Colibri protocol (ActiveAudioSsrcs discovery) - Programmatic SDP construction via cricket::SessionDescription API Key implementation details: - Loopback ICE enabled (network_ignore_mask=0) for localhost SFU - RTP header extensions copied from local offer per m-line (BUNDLE-safe) - MID extension excluded from remote answer to prevent wrong-channel routing - Renegotiation mirrors local offer mids exactly in constructed answer - Synthetic audio levels (0.1) for known remote SSRCs - Serialized renegotiation (one offer/answer at a time) Squashed from: - feat: add GroupInstanceReferenceImpl — PeerConnection-based group call client - fix: add missing jsep_session_description.h include - fix: enable loopback ICE and add remote candidates - fix: add RTP header extensions to SDP answer - fix: rewrite buildRemoteAnswer to mirror local offer mids for renegotiation - fix: simplify audio level polling to use known remote SSRCs directly #tgcalls

TelegramMessenger/tgcalls/experimental • 616810f • 38 files, +38/-0 build: add #include <cstdint> for GCC 15 compatibility TelegramMessenger/tgcalls/experimental • 24fd51b • 7 files, +2218/-19 feat: SCTP signaling improvements for reliable connection establishment Add writable gate for role-based SCTP handshake ordering: caller (isOutgoing=true) starts writable and sends INIT immediately; callee starts not-writable and defers Connect() until first received packet triggers setWritable(true). Implement CustomDcSctpSocket to fix WebRTC's missing timer backoff cap on t1_init and t1_cookie handshake timers. Without this, simultaneous-open under packet loss causes 20+ second stalls due to unlimited exponential backoff (1s, 2s, 4s, 8s...). With the fix: 400ms init, 750ms max backoff, yielding ~18 attempts in 15s and 100% success at 30% loss. Timer values are configurable via JSON custom parameters: - network_sctp_t1_init_ms, network_sctp_t1_cookie_ms, network_sctp_max_backoff_ms Squashed from: - feat: add SCTP writable gate for role-based handshake ordering - chore: whitespace cleanup in NativeNetworkingImpl - fix: CustomDcSctpSocket with t1 timer backoff cap for signaling SCTP TelegramMessenger/tgcalls/experimental • 212a874 • 1 files, +5/-0 fix: use-after-free in InstanceV2ReferenceImpl::writeStateLogRecords() writeStateLogRecords() captured a raw Call* pointer on the media thread and posted it to the worker thread. If stop() called _peerConnection->Close() (which destroys Call) between the post and worker thread execution, the worker thread would dereference a dangling pointer. WebRTC's call_ptr_ is Call* const and never nulled after Close(), so the existing null check didn't catch this. Fix: add _isStopped atomic flag, set before Close() in stop(), checked in the worker thread lambda before accessing call. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> #tgcalls
