Custom / WHIP (MediaMTX)Not connected
Go live

Browsers cannot publish classic RTMP directly. Prefer a WHIP endpoint (Cloudflare Stream, MediaMTX, etc.). Keys are stored only on this device. Never claim live until the ingest accepts the session.

Video call

1:1 WebRTC call using public STUN. Share the invite text with the other person. For production multi-party, connect a signaling server later.

Voice presence

Uses Web Audio on your mic stream. Monitoring routes processed audio to speakers/headphones — use headphones to avoid feedback.

Text to speech

Browser engine works offline with no install. Qwen3-TTS (Apache-2.0) needs a local server — see services/qwen-tts-setup.md. MediaMTX for WHIP: docker compose -f services/docker-compose.yml up -d then WHIP URL http://localhost:8889/swapbm/whip.

Live captions (browser STT)
Captions from mic
Captions appear here when enabled.

Uses the Web Speech API (Chrome/Edge/Safari). Audio stays on device.

Local machine connection

Heavy AI (FaceFusion, Deep-Live-Cam, MediaMTX, NVIDIA) runs on your PC. This site talks to a companion on 127.0.0.1 only.

Replay = rolling WebM buffer. OBS GetScenes uses OBS WebSocket 5 (local). Models are registered on-device only — weights are not uploaded. Multi-destination: set Custom WHIP plus another destination URL; Go Live prefers the first WHIP-capable target.

    


      True cinematic live face swap needs a local NVIDIA/AMD GPU pipeline (not the browser alone). Use Deep-Live-Cam, FaceFusion, or StreamingSwap as the bridge; swapBM routes studio video to/from it and publishes via WHIP/OBS.

    

    

      
Best open stacks (2026)

      

        Live stream: Deep-Live-Cam / LiveFaceCam (single photo, webcam, ~20–60 FPS on RTX 4090 with TensorRT) · FaceFusion 3.x · StreamingSwap (~20 FPS / RTX 4090, long video stable).


        Recorded video: FaceFusion (file mode, enhancers, multi-face) · Deep-Live-Cam video mode.


        OBS path: GPU app → virtual camera → OBS, or swapBM WHIP → MediaMTX → OBS Browser Source / RTMP.

OBS & USB

      

        USB cameras appear in Studio → Camera device list (browser enumerates UVC devices).

        OBS: Stream tab → MediaMTX WHIP, or capture this browser window / virtual cam from local GPU app.

        Beat-OBS direction: one app for capture + AI face + TTS + multi-destination WHIP — OBS remains stronger for complex multi-scene desktop production until a native GPU companion ships.
