Usage

Basic Example

from meeting_detection import init, is_meeting_active, get_last_detection_details

# Initialize the engine (starts background polling every 2 seconds)
init()

# Check current status
active = is_meeting_active()
print(f"Meeting active: {active}")

# Get detailed detection information
details = get_last_detection_details()
if details:
    print(f"App: {details.app_name}")
    print(f"Reason: {details.reason}")
    if details.meeting_url:
        print(f"URL: {details.meeting_url}")

Event-Based Monitoring

import time
from meeting_detection import init, on_meeting_start, on_meeting_end

# Initialize the engine
init()

# Register callbacks
def handle_meeting_start(details):
    print(f"🎥 Meeting started!")
    print(f"  App: {details.app_name}")
    print(f"  Reason: {details.reason}")
    if details.meeting_url:
        print(f"  URL: {details.meeting_url}")

def handle_meeting_end(details):
    print(f"👋 Meeting ended!")
    print(f"  App: {details.app_name}")

on_meeting_start(handle_meeting_start)
on_meeting_end(handle_meeting_end)

# Keep the script running
print("Monitoring for meetings... (Press Ctrl+C to stop)")
try:
    while True:
        time.sleep(1)
except KeyboardInterrupt:
    print("Stopped monitoring.")

Command-Line Tool Example

#!/usr/bin/env python3
"""Simple CLI tool to check meeting status."""

import sys
from meeting_detection import init, is_meeting_active

def main():
    init()

    # Wait for first detection cycle
    import time
    time.sleep(3)

    if is_meeting_active():
        print("In a meeting")
        sys.exit(0)
    else:
        print("Not in a meeting")
        sys.exit(1)

if __name__ == '__main__':
    main()

• callback: Function that receives DetectionDetails when a meeting starts

on_meeting_end(callback: Callable[[DetectionDetails], None])

Register a callback for when a meeting ends.

def handle_end(details):
    print(f"Meeting ended: {details.app_name}")

on_meeting_end(handle_end)

Parameters:

• callback: Function that receives DetectionDetails when a meeting ends

get_last_detection_details() -> Optional[DetectionDetails]

Get details about the last detection cycle.

details = get_last_detection_details()
if details:
    print(f"App: {details.app_name}")
    print(f"Active: {details.active}")

Returns: DetectionDetails or None if no detection has occurred yet

Data Classes

DetectionDetails

Contains detailed information about meeting detection.

Attributes:

• active (bool): Whether a meeting is currently active
• score (int): Detection score (for backward compatibility)
• app_name (str | None): Name of the meeting application
• reason (str): Detection reason (e.g., "NativeAppWithNetwork(Zoom)")
• meeting_url (str | None): Meeting URL (for browser-based meetings)
• signals (SignalsBreakdown): Breakdown of detection signals

SignalsBreakdown

Breakdown of all detection signals.

Attributes:

• meeting_app (SignalDetails): Meeting app detection signal
• meeting_window (SignalDetails): Meeting window detection signal
• microphone (SignalDetails): Microphone active signal
• camera (SignalDetails): Camera active signal

SignalDetails

Information about a specific detection signal.

Attributes:

• active (bool): Whether this signal is active
• weight (int): Weight of this signal in the overall score

How It Works

Two-Tier Detection Algorithm

The library uses a two-tier detection algorithm to accurately identify active meetings:

Tier 1: Native Meeting Apps

For native apps (Zoom desktop, Teams desktop, Webex desktop), network connections are the primary signal:

• Zoom: UDP port 8801 is a strong indicator (works with IP addresses)
• Teams/Webex: STUN ports (3478-3481) or meeting domains with ESTABLISHED connections
• Decision: If network connections active → MEETING ACTIVE

Tier 2: Browser-Based Meetings

For browser-based meetings (Google Meet, Teams web, Webex web), browser tab URLs are definitive:

• Google Meet: Validates meeting code format (xxx-yyyy-zzz), excludes landing pages
• Teams/Webex web: Pattern matching on meeting URLs
• Decision: If meeting URL detected → MEETING ACTIVE

Google Meet Code Validation

Google Meet URLs require special validation to avoid false positives:

• Format: xxx-yyyy-zzz (3 segments separated by hyphens)
• Each segment: 2-5 lowercase letters only
• Total: 8-15 characters (excluding hyphens)
• Excludes: /landing, /new, /join, empty paths

Example valid codes:

• abc-def-ghi ✅
• cih-fjjf-pfd ✅

Example invalid:

• abc-def ❌ (only 2 segments)
• ABC-def-ghi ❌ (uppercase)
• abc-d3f-ghi ❌ (contains digit)

Accuracy Parity with Rust Implementation

This Python implementation is designed to maintain 100% accuracy parity with the original Rust implementation. Critical components that ensure this:

1. Google Meet Validation (config.py:is_valid_google_meet_code)

   • Exact port of Rust logic for meeting code validation
   • Prevents false positives from landing pages

2. Network Detection (network.py:detect_meeting_network_activity)

   • Zoom UDP port 8801 detection (works without domain matching)
   • Teams STUN ports (3478-3481)
   • Proper handling of connection states (ESTABLISHED, CLOSED, UNKNOWN)

3. Two-Tier Algorithm (detector.py:detect)

   • Native apps checked before browsers
   • Browsers skipped in Tier 1, handled in Tier 2
   • State transitions tracked correctly

Troubleshooting

Permissions

The library requires certain macOS permissions:

• Terminal/Python: May need accessibility permissions for osascript
• Network Access: Uses lsof to check network connections (no special permissions required)

Debugging

Enable debug logging:

import logging
logging.basicConfig(level=logging.DEBUG)

Get detailed detection information:

details = get_last_detection_details()
if details:
    print(f"Active: {details.active}")
    print(f"Reason: {details.reason}")
    print(f"Score: {details.score}")
    print(f"Signals: {details.signals}")
