Alpha scope (what we ship)
| In scope | Out of scope (frozen) |
|---|---|
| LAN discover → PIN → cast → stop | Internet relay, TLS on stream |
| UDP or TCP transport (must match on both devices) | QUIC, WebRTC, USB-tether transport in UI |
| H.264 + AAC (Android 10+ audio) | Passthrough video, Opus/Speex as default |
| Single receiver per cast session | 1:N multi-receiver (disabled in CastConfig) |
| Stream protection None (default) | FEC/NACK soak required for alpha sign-off |
| Screen capture (full / user-choice on API 34+) | Secondary-display capture, Miracast in-app |
| Camera cast (API 29+, best-effort) | Live sender mirror while casting |
| Receiver playback + notification stop | Play Store / AdMob production |
| On-demand remote debug (RSSH, hidden) — developer settings + BE | WireGuard-only remote access as alpha deliverable |
Code gate: CastConfig.ALPHA_FEATURE_FREEZE = true hides experimental transports and turns off multi-receiver selection.
Recommended defaults (both devices)
Set in Settings (or use fresh install defaults):
| Setting | Sender | Receiver |
|---|---|---|
| Transport | UDP | UDP |
| Stream protection | None | None |
| Quality | Medium | Medium |
| Resolution | Adaptive (or HD 720p if rotation is shaky) | — |
| Video codec | Auto | Auto |
| Audio | On (if API 29+) | Play incoming audio: On |
| Capture mode | Full screen (or User choice on Android 14+) | — |
| PIN | Same on both (default 1234) |
Same |
Rotation soak: On Mediatek / Freeme senders (e.g. BL6000), prefer system rotation lock ON during first alpha pass; then repeat with lock OFF to validate debounced reconfigure.
Feature freeze checklist (engineering)
| Item | Status |
|---|---|
ALPHA_FEATURE_FREEZE — UDP/TCP only in settings |
Done |
| Multi-receiver disabled for alpha | Done |
| Stored QUIC/WebRTC transport clamped to UDP on load | Done |
| Camera strings (permission vs unavailable) | Done |
README matches CastConfig / CastSettings defaults |
Done |
| Receiver: keyframe idle grace + debounced sender resize | Done (verify on soak) |
| Preview paused during cast (single MediaProjection) | Done |
| Developer-only: FEC, QUIC, USB-tether, immersive presets | Gated (dev settings) |
Alpha app sign-off (manual QA)
Run on two physical devices, same Wi‑Fi subnet. Record build: About / versionName from APK, git commit, date.
A. Smoke (required — all must pass)
| # | Step | Pass |
|---|---|---|
| A1 | Install same debug/release APK on sender + receiver | ☐ |
| A2 | Receiver: Receive → Start listening → notification Listening / Ready | ☐ |
| A3 | Sender: Send → discover receiver → correct PIN → approve capture | ☐ |
| A4 | Video appears on receiver within 15 s of auth | ☐ |
| A5 | Audio audible (if enabled and API 29+) within 20 s | ☐ |
| A6 | Sender notification shows Casting with resolution | ☐ |
| A7 | Stop from sender notification → stream ends, receiver returns to idle | ☐ |
| A8 | Stop from receiver notification → sender stops cleanly | ☐ |
| A9 | Second cast without reinstall (A2→A7 again) | ☐ |
B. Resilience (required)
| # | Step | Pass |
|---|---|---|
| B1 | Sender home → cast 5 min, no reboot / ANR | ☐ |
| B2 | Receiver app to background 2 min → return → video recovers or clean idle | ☐ |
| B3 | Receiver rotate once → video continues or recovers within 10 s | ☐ |
| B4 | Sender rotate with rotation lock ON → 5 min stable | ☐ |
| B5 | Sender rotate with lock OFF (optional / device-specific) → no permanent freeze; note if reboot | ☐ |
C. Settings matrix (pick one row for official alpha demo)
| Profile | Transport | Protection | Use |
|---|---|---|---|
| Alpha default | UDP | None | Primary sign-off |
| Fallback | TCP | None | If UDP glitches on your AP |
| # | Step | Pass |
|---|---|---|
| C1 | UDP + None: 10 min soak | ☐ |
| C2 | (Optional) TCP + None: 10 min soak | ☐ |
D. Regression guards (quick)
| # | Step | Pass |
|---|---|---|
| D1 | Wrong PIN → clear error, no crash | ☐ |
| D2 | Mismatched transport (sender TCP / receiver UDP) → fails fast with message | ☐ |
| D3 | Camera mode (if used): permission grant → cast 2 min | ☐ |
| D4 | Calibration test mode → pattern on receiver | ☐ |
E. Known limitations (not alpha blockers)
- No TLS; LAN cleartext.
- UDP may drop frames under congestion.
- No live preview on sender while casting.
- Some apps silent under playback capture policy.
- Heavy rotation on some OEMs may still stress system WFD/WM (watchdog) — document device + lock state.
LAN alpha approved when: all A, B1–B4, and C1 pass on your reference sender + receiver pair. Full alpha additionally requires backend deploy and F1–F5 (RSSH).
Log capture (when something fails)
From repo root:
./scripts/alpha-qa-logcat.sh SENDER_SERIAL RECEIVER_SERIAL
Or manually:
adb -s SENDER logcat -s ScreenCastService:* ReceiverCastService:* AndroidCast:* SenderScreenPreview:*
adb -s RECEIVER logcat -s ReceiverCastService:* AndroidCast:*
Alpha backend (optional for LAN-only alpha)
LAN cast demo does not require OTA/crash backend. For full alpha (owner agreement) with updates, crash upload, and production remote debug:
| Item | Notes |
|---|---|
Host examples/ota/v0/ |
See OTA.md |
| Deploy crash reporter | See CRASH_REPORTER.md |
| Configure URLs | Developer settings or local.properties |
| RSSH remote access | Alpha essential: hidden mode (no VPN consent); device polls BE, opens outbound reverse SSH to bastion; operator connects via BE UI whitelist + session. WireGuard v1 is lab-only for alpha sign-off. See REMOTE_ACCESS_IMPL.md |
| Email + 2FA auth | Alpha essential: info@/admin@ forward to Gmail; user register + email verify + TOTP; see 20260607-2FA-email-mobile-auth-flow.md |
F. Remote access — RSSH (required for full alpha sign-off)
| # | Step | Pass |
|---|---|---|
| F1 | Developer settings → RSSH (not WireGuard) → no Android VPN permission dialog | ☐ |
| F2 | Device polls BE (type: ra); operator whitelists device + opens session in dashboard |
☐ |
| F3 | Reverse tunnel active; operator reaches device debug endpoint on bastion (shell or agreed file path) | ☐ |
| F4 | Session expiry / disable tears down tunnel; BE notified | ☐ |
| F5 | No persistent VPN key icon while remote debug is active | ☐ |
Full alpha approved when: LAN sign-off (A, B1–B4, C1) and backend items above and F1–F5 and G1–G6 pass on reference environment.
G. Email + registration / 2FA (required for full alpha sign-off)
| # | Step | Pass |
|---|---|---|
| G1 | Inbound mail to info@apps.f0xx.org arrives at configured Gmail (forward) |
☐ |
| G2 | BE sends verification email (SMTP); link opens on mobile browser | ☐ |
| G3 | New user registers → verifies email → enrolls TOTP (QR) | ☐ |
| G4 | Login requires password + TOTP; lockout after repeated failures | ☐ |
| G5 | User can set recovery email; admin/root can clear auth lockouts | ☐ |
| G6 | Register/login UI matches crashes console theme (EN/RU, mobile layout) | ☐ |
Ending feature freeze
- Complete sign-off table above; note devices + APK build id in git tag message.
- Tag release on
masterper GIT_FLOW.md. - To re-enable experiments on a dev branch: set
CastConfig.ALPHA_FEATURE_FREEZE = falseand restoreMULTI_RECEIVER_ENABLEDas needed.
Post-alpha priorities: rotation-stable encode path, encoder thumbnail on sender, secondary-display capture (roadmap D).
