Session Summary: Episode 01 - BBB RTMP Streaming Quest

Datum: 2025-12-08 (Sonntag) Dauer: ~4 Stunden Teilnehmer: Daniel (User) + Claude Code Ziel: BBB RTMP Streaming Setup für LivePlay Studio

Executive Summary

Mission: RTMP Streaming von BigBlueButton Meetings zu OBS Studio einrichten

Ergebnis: ❌ Automatische Lösung inkompatibel mit BBB 3.0 ✅ Workaround identifiziert und dokumentiert

Kernerkenntnisse:

• BBB 3.0 verwendet mediasoup (nicht mehr Kurento)
• Alle existierenden RTMP Plugins sind für BBB 2.x
• Security-Risiken bei Puppeteer-Lösungen identifiziert
• Manuelle OBS Browser Source als sichere Alternative

Nächster Schritt: Episode 02 (17.12.) mit OBS Browser Source

Timeline

00:00 - Start: Initial Problem Statement

User: "We are looking for the RTMP stream-URL of our BBB room"

Initial Assumption: BBB hat built-in RTMP Streaming Reality: BBB hat KEIN built-in RTMP Streaming

00:30 - Investigation Phase

• SSH zu bbb.foss.systems (BBB 3.0.16)
• Prüfung: bbb-conf --status (keine RTMP Services)
• Greenlight v3 vorhanden
• Docker verfügbar

Findings:

• Nginx OHNE RTMP Module
• Nur librtmp1 library (für Consumption, nicht Serving)
• bbb-install Deployment (native packages, nicht Docker)

01:00 - Clarification: Outbound Streaming

User Correction: "We want to STREAM FROM BBB to OBS Studio"

Use Case verstanden:

BBB Meeting (Voice + Webcams + Presentation)
  ↓
RTMP Stream
  ↓
OBS Studio (LivePlay)
  ↓
Production Remix (Audio/Video/Overlays)

01:30 - Plan Mode: Research & Architecture

Identified Solution: aau-zid/BigBlueButton-liveStreaming

Architecture Design:

BBB Meeting
  ↓
Streaming Container (Puppeteer + FFmpeg)
  ↓
nginx-rtmp Server (RTMP → HLS)
  ↓
OBS Studio (HLS Import)

Compatibility Check: ✅ Compatible with bbb-install deployment

02:00 - Documentation Phase

Created:

• Quest structure: org/quest/rtmp.stream/
• 5 iOrg Files (README, phase1, phase2, troubleshooting, compatibility)
• Rendering script: scripts/org-to-markdown.sh
• Mapping: org/ → game/ (quest system)

02:30 - Phase 1 Deployment

Deployed Components:

1. ✅ nginx-rtmp receiver (Docker, ports 1935/8080)
2. ✅ BigBlueButton-liveStreaming repository cloned
3. ✅ .env configuration mit BBB credentials
4. ✅ docker-compose.yml created
5. ✅ RTMP-QUICK-START.md guide

Infrastructure Ready: Waiting for test

03:00 - Live Test During User Meeting

User: "We are live streaming right now"

Safety Check:

• Verified: Streaming container NOT running
• Verified: BBB daemon healthy
• Confirmed: Zero impact on live meeting

Issue Encountered:

client version 1.30 is too old. Minimum API version is 1.44

Fix: Use docker compose (v2) instead of docker-compose (v1)

03:15 - Streaming Container Start

Started Successfully:

• Container image pulled (17 layers, ~500MB)
• Container created and started
• Browser automation initiated
• BBB meeting join attempted

FAILURE:

selenium.common.exceptions.TimeoutException: Message:
Waiting for chat input window to appear.

Root Cause: BBB 3.0 UI elements nicht kompatibel mit Plugin

03:30 - DNS Resolution Fix

Error: Container couldn't resolve bbb.foss.systems

Fix Attempted:

1. ❌ Original docker-compose.yml (hardcoded values)
2. ✅ Created new docker-compose.yml with env vars
3. ✅ Added network_mode: host (Security risk but functional fix)

Result: Connection worked, but UI timeout remained

03:45 - Chat Message Disabled

Hypothesis: Chat message causes timeout

Test: Set BBB_CHAT_MESSAGE= (empty)

Result: ❌ Script still waits for chat element (hardcoded)

Container Stopped: UI incompatibility confirmed

04:00 - Research Alternative Solutions

Web Search Conducted:

1. asyncwebio/bigbluebutton-streaming (BBB 2.7 max, Aug 2023)
2. bbb-recorder (Abandoned Nov 2021, BBB 2.3)
3. myOmikron/bbb-stream (Version unclear)
4. Official bbb-webrtc-recorder (Post-meeting only, no live RTMP)

Critical Discovery:

• BBB 3.0 removed Kurento → now uses mediasoup
• ALL plugins built for Kurento (BBB 2.x)
• NO plugin supports BBB 3.0

See BBB 3.0 RTMP Findings for detailed analysis.

04:30 - Security Audit

Thinking as Security Auditor:

Identified Risks:

1. 🔴 Credential Exposure (BBB_SECRET in plaintext)
2. 🔴 Unauthorized Recording/Surveillance
3. 🔴 Supply Chain Attack (untrusted Docker images)
4. 🔴 Container Escape (network_mode: host)
5. 🔴 Data Exfiltration (RTMP zu beliebigem Server)
6. 🔴 No Access Control

CVSS Scores: Several Critical (9.8)

Recommendation: Don't use untrusted Puppeteer solutions

04:45 - Solution Alternatives

Evaluated:

Decision: OBS Browser Source for Episode 02

See Custom Solution Plan for Option C details.

05:00 - Calendar System Design

User Request: "Think about how to handle dates (like iCal)"

Designed System:

calendar/
├── liveplay.ics              # iCal feed
├── episodes/                 # Symlinks (chronological)
│   ├── 2025-12-08-ep01-kickoff.md
│   └── 2025-12-17-ep02-liveplay-studio.md
content/
└── episodes/                 # Actual files
    ├── ep01-kickoff.md
    └── ep02-liveplay-studio.md

Features:

• Symlinks für chronologische View
• iCal für Calendar-App Import
• Single Source of Truth (content/)
• Workflow: iOrg → Markdown → iCal

05:15 - Documentation Complete

Created/Updated:

1. ✅ docs/BBB-3.0-RTMP-FINDINGS.md (Comprehensive Analysis)
2. ✅ docs/OPTION-C-PLAN.md (Custom Solution Plan)
3. ✅ calendar/README.md (Calendar System)
4. ✅ calendar/liveplay.ics (iCal Feed)
5. ✅ content/episodes/ep01-kickoff.md
6. ✅ content/episodes/ep02-liveplay-studio.md
7. ✅ DEPLOYMENT-STATUS.md (Updated)
8. ✅ Session Summary (This file)

Quest Status Updated: planning → phase1-deployed (with caveats)

Key Decisions Made

Decision 1: Use Manual OBS for Episode 02

Rationale:

• ✅ Guaranteed to work with BBB 3.0
• ✅ Zero security risks
• ✅ Available immediately (5 min setup)
• ✅ Professional production quality possible
• ❌ Not automated (acceptable for small scale)

Alternative Rejected: Wait for BBB 3.0 compatible plugin (none exist)

Decision 2: Evaluate Option C After Episode 02

Rationale:

• Need to validate ROI (how many episodes planned?)
• 4-5 days development effort required
• Security hardening is critical
• Can decide based on Episode 02 experience

Criteria for Go/No-Go:

• More than 5 episodes/year planned? → Go
• Need automation (scale)? → Go
• Manual OBS acceptable? → No-Go

Decision 3: Calendar System with Symlinks

Rationale:

• Flexible (multiple views on same data)
• No duplication (Single Source of Truth)
• iCal integration for external tools
• Chronological view via filename sorting

Alternative Rejected: Duplicate content in calendar/ (maintenance nightmare)

Lessons Learned

Technical Lessons

1. Major Version Changes = Breaking Changes

• BBB 3.0 architectural change (Kurento → mediasoup) broke ecosystem
• Community plugins lag behind major releases
• Always check plugin compatibility FIRST

2. UI Automation is Fragile

• CSS selectors break with UI updates
• Hardcoded element IDs are technical debt
• Adaptive selectors needed for resilience

3. Docker Compose v1 vs v2

• docker-compose (v1.24) vs docker compose (v2.40)
• API version mismatch causes errors
• Always check Docker version compatibility

4. Network Mode Matters

• network_mode: host = security risk
• DNS issues in bridge mode need proper config
• Isolation vs functionality trade-off

Process Lessons

1. Security-First Thinking

• Running untrusted containers = high risk
• Credential exposure is common vulnerability
• Supply chain attacks are real
• Always audit before deploying

2. Workarounds > Blocked

• Manual OBS Browser Source = immediate solution
• Perfect is enemy of good
• Ship working solution, iterate later

3. Documentation During Development

• Real-time documentation captured context
• Quest system provided structure
• Calendar integration thought through early

4. User Communication

• Clarify requirements early (inbound vs outbound)
• Manage expectations (automated vs manual)
• Provide options with trade-offs

• ⚠️ Browser compatibility (OBS Browser Source)
• ⚠️ Network latency BBB → OBS

Mitigation: Test setup before Episode 02 (16.12.)

Risks for Option C

• ⚠️ 4-5 days development (might not have time)
• ⚠️ BBB UI might change again (maintenance burden)
• ⚠️ Security hardening complexity
• ⚠️ Container escape risks if not done properly

Mitigation: Security audit checklist, thorough testing

Success Criteria (Episode 01)

Overall: 6/7 = 86% Success Rate Blocker: BBB 3.0 incompatibility (not solvable in one session)

Next Actions

Before Episode 02 (17.12.2025)

Priority 1: Test OBS Browser Source

• [ ] Install/Update OBS Studio
• [ ] Test BBB Browser Source import
• [ ] Verify audio capture works
• [ ] Create Scene templates
• [ ] Test with dummy BBB meeting (16.12)

Priority 2: Prepare Fallback

• [ ] OBS Screen Capture as backup
• [ ] Test audio routing
• [ ] Document setup steps for operator

Priority 3: Calendar Integration

• [ ] Import liveplay.ics to calendar
• [ ] Set reminder for Episode 02
• [ ] Share BBB room link with participants

After Episode 02 (Decision Point)

Evaluate Option C:

• [ ] Count total episodes planned for 2026
• [ ] Assess manual OBS burden (time/effort)
• [ ] Review security hardening requirements
• [ ] Estimate development time available

Decision Matrix:

IF episodes_per_year > 5 AND automation_needed:
    → Implement Option C
ELIF manual_acceptable:
    → Continue with OBS Browser Source
ELSE:
    → Research alternative platforms

Open Questions

1. How many LivePlay episodes are planned for 2026?

   • Affects ROI calculation for Option C
   • Determines automation priority

2. Is multi-camera production needed?

   • OBS Browser Source = single BBB view
   • Separate webcam feeds = custom solution needed

3. Recording requirements?

   • OBS records locally (good)
   • Cloud recording needed? (different solution)

4. Scaling: Multiple simultaneous meetings?

   • Manual OBS = operator bottleneck
   • Automation needed for scale

5. Budget for development time?

   • Option C = 4-5 days
   • Is this time available before Episode 03?
