PLATFORMS — per-platform join packs & doctor output
Join packs are the browser driver's per-platform adapters. Each pack is a versioned file (TOML) pinning the selectors and flow for one platform at a stated browser/client build. Selector drift is the primary maintenance cost; packs are pinned so drift is a loud failure, not a silent one.
Pack format (browser driver, post-MVP)
[meta]
platform = "jitsi"
pack_version = 3
tested_client = "meet.jit.si 2026-06"
url_pattern = '^https://[^/]+/#?[a-zA-Z0-9-]+$'
[join]
# Ordered actions: goto → name-entry → premit-wait → admit → device-grant
steps = ["goto", "grant_permissions", "enter_name", "join"]
selectors = { enter_name = "#premeeting-name-input", join = "[data-testid='join-button']" }
[devices]
camera_selector = "video"
mic_selector = "audio"
Doctor output — freestream probe --platform <p> prints, per platform:
pack availability + version, browser build found, virtual camera present,
virtual mic present, and a join dry-run result.
Platform status (v0.1.0)
| Platform | Path | Status |
|---|---|---|
| LiveKit (incl. self-hosted Jitsi-via-LiveKit) | livekit driver, native WebRTC |
MVP target — no selectors, no ToS gray zone |
| Jitsi (meet.jit.si) | browser pack or LiveKit backend | MVP target via LiveKit driver |
| Google Meet | browser pack | Blocked until pack + virtual-camera validation; ToS gray zone (see CONSENT.md) |
| Zoom | browser pack | Same |
| Teams | browser pack | Not planned in MVP |
| SIP audio | sip driver |
Post-MVP |
Ship order (from the concept's next-steps)
- Jitsi/LiveKit first — open stack, native driver, zero selector drift.
- Virtual-camera injection on modern macOS browser clients (Chrome + BlackHole) — validated per-pack before any Meet/Zoom pack ships.
- Meet/Zoom packs last, gated on a ToS review, with the browser pack version pinned to a tested client build.
Virtual camera / mic
- Linux: v4l2loopback kernel module + PulseAudio/PipeWire null sink.
freestream doctorchecks module presence (/dev/v4l2byidscan) and sink creation rights. - macOS: OBS Virtual Camera or a CoreMediaIO DAL plugin for video; BlackHole for loopback audio. Screencapture-kit permission required.
- Windows: post-MVP; OBS Virtual Camera is the reference backend.
