🦀 CrabCamera: Professional Desktop Camera & Audio Plugin for Tauri 📷🎙️

🦀 CrabCamera will be free forever. 🦀 No asterisks. No "free for now." No pivot to paid.

🦀 What is CrabCamera?

🦀 CrabCamera is the first production-ready desktop camera + audio plugin for Tauri applications, engineered with professional software development practices. It provides unified camera and audio access across Windows, macOS, and Linux with enterprise-grade reliability, synchronized A/V recording, and zero-config setup. Built with memory safety, comprehensive testing, and performance optimization at its core.

🎯 Strategic Focus: Camera Capture Excellence

After extensive development and multiple attempts at implementing WebRTC streaming, we've made a strategic decision to focus CrabCamera exclusively on camera capture and recording excellence.

🛡️ Engineering Philosophy: The Invariant Superhighway

CrabCamera is built differently. We don't just "check for errors"; we enforce architectural guarantees through what we call Predictive Property-Based Testing (PPT) or the Invariant Superhighway.

Deterministic Reliability: Every critical data path (video encoding, audio sync, frame merging) is paved with "toll booths"—runtime invariant checks that enforce strict contracts about state validity.
Self-Verifying Architecture: The system monitors its own health. In debug builds, it panics immediately on logic violations. In production, it ensures data integrity before it ever reaches the user.
Contract-Driven Tests: Our test suite doesn't just check outputs; it checks that the safety mechanisms themselves were engaged. We verify that the guards are watching.

This methodology (adapted from high-reliability systems engineering) ensures that CrabCamera isn't just "working code"—it's a verifiable system.

Why We Removed WebRTC

The Challenge: WebRTC streaming represents a significant expansion beyond our core competency. While technically feasible, it introduced substantial complexity:

Real-time media server requirements
Network protocol implementation (ICE, STUN, TURN)
Hardware-accelerated encoding across platforms
Browser signaling and peer connection management

The Decision: Rather than dilute our focus, we've chosen to excel at what we do best: professional camera access and recording. This allows applications to choose their preferred streaming solutions while benefiting from CrabCamera's proven camera infrastructure.

The Result: A sharper value proposition - CrabCamera is now the definitive choice for camera capture in Tauri applications, with clear boundaries that ensure reliability and maintainability.

Streaming Integration Options

For applications needing streaming, we recommend:

Browser-Native WebRTC: Use CrabCamera for capture, then stream via standard browser WebRTC APIs
Specialized Libraries: Integrate dedicated streaming libraries alongside CrabCamera
Tauri Channels: For simple IPC-based streaming within your application

This approach gives you maximum flexibility while keeping CrabCamera focused and reliable.

🦀 Quick Start (30 seconds) 📷🎙️

Installation

[dependencies]
crabcamera = { version = "0.6", features = ["recording", "audio"] }
tauri = { version = "2.0", features = ["protocol-asset"] }

Tauri Integration

// src-tauri/src/main.rs
use crabcamera;

fn main() {
    tauri::Builder::default()
        .plugin(crabcamera::init())
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

Frontend Integration

To call CrabCamera commands from your frontend, use the plugin:crabcamera| prefix with the Tauri invoke function.

1. Using a Bundler (Vite, Webpack, etc.)

import { invoke } from '@tauri-apps/api/core';

// Initialize the camera system (Required)
try {
  await invoke('plugin:crabcamera|initialize_camera_system', {
    params: {
        camera_index: 0,
        resolution: "1920x1080",
        fps: 30,
        format: "MJPEG"
    }
  });
  console.log('Camera System Initialized');
} catch (e) {
  console.error('Init failed:', e);
}

// Capture a photo
async function takePhoto() {
  const path = await invoke('plugin:crabcamera|capture_single_photo', {
      path: "capture.jpg"
  });
  console.log('Saved to:', path);
}

2. Using Vanilla JS (No Bundler)

Enable withGlobalTauri: true in src-tauri/tauri.conf.json:

{
  "app": {
    "withGlobalTauri": true
  }
}

Then access via window.__TAURI__:

const { invoke } = window.__TAURI__.core;
await invoke('plugin:crabcamera|initialize_camera_system');

Important: All CrabCamera commands must be invoked with the plugin:crabcamera| prefix.

Frontend: Professional Photo Capture

import { invoke } from '@tauri-apps/api/core';

// Get cameras with quality analysis
const cameras = await invoke('plugin:crabcamera|get_available_cameras');
const format = await invoke('plugin:crabcamera|get_recommended_format');

// Capture with quality validation
const photo = await invoke('plugin:crabcamera|capture_single_photo', {
  deviceId: cameras[0].id,
  format: format,
  quality: { min_score: 0.8 }  // Professional quality threshold
});

Frontend: Synchronized A/V Recording

import { invoke } from '@tauri-apps/api/core';

// Professional A/V setup
await invoke('plugin:crabcamera|initialize_camera_system');
const audioDevices = await invoke('plugin:crabcamera|list_audio_devices');
const audioDevice = audioDevices.find(d => d.is_default);

// Enterprise-grade recording with perfect sync
await invoke('plugin:crabcamera|start_recording', {
  outputPath: 'professional_recording.mp4',
  videoConfig: {
    deviceId: cameras[0].id,
    codec: 'h264',
    width: 1920,
    height: 1080,
    fps: 30.0
  },
  audioConfig: {
    deviceId: audioDevice.id,
    codec: 'opus',
    sampleRate: 48000,
    channels: 2
  }
});

// Automatic PTS-based synchronization
await invoke('plugin:crabcamera|stop_recording');
console.log('🎬 Professional recording complete with perfect A/V sync');

🦀 Why CrabCamera Will Always Be Free 📷

I built CrabCamera because desktop applications deserve native camera access without the limitations of web APIs or mobile-only plugins.

This is my commitment: CrabCamera stays MIT licensed, forever. If you want to support development, sponsor it. If you don't, just build something incredible with it.

🦀 CrabCamera saves developers weeks of cross-platform camera integration. If it's useful, consider sponsoring for $5/month — less than a coffee, infinitely more valuable than web API limitations. 🦀

Future: Enhanced codecs and formats

🏗️ Architecture Excellence

Professional Pipeline:
  Camera/Microphone → Direct Hardware Access → Quality Validation
                        ↓
  Encoding Pipeline: H.264/Opus → MP4 Output
                        ↓
  Synchronization: PTS-based A/V sync with sub-frame accuracy

💻 Enterprise Platform Support

✅ Windows: WASAPI audio + MediaFoundation video + MP4 recording
✅ macOS: AVFoundation audio/video + MP4 recording
✅ Linux: ALSA audio + V4L2 video + WebRTC streaming

🔒 Security & Production Readiness

📈 Engineering Metrics

Test Coverage: 163 automated tests with property-based validation
Performance: 10-100x encoding improvement through intelligent caching
Code Quality: Clean compilation, single benign deprecation
Media Processing: Professional H.264/Opus encoding with A/V synchronization
Test Coverage: 80%+
Compilation Time: 45s (release), 15s (debug)
Binary Size: +2.1MB (audio libs) vs v0.4.1

🎉 v0.4.1: Bug Fixes, Performance & DX

Critical Fix: Mock camera was incorrectly used during cargo run
- Mock camera selection is now explicit via CRABCAMERA_USE_MOCK=1
PNG Save Fixed: save_frame_to_disk() now properly encodes PNG/JPEG
Performance: Camera warmup reduced from 10 frames to 5 frames
macOS Fixed: Objective-C block syntax and nokhwa API compatibility

🎉 v0.4.0: Quality Intelligence & Configuration

Quality Validation: Automatic blur/exposure detection with retry
TOML Configuration: Full runtime config with hot-reload
Focus Stacking: Computational photography for macro shots
Device Monitoring: Hot-plug detection for camera connect/disconnect

🎉 v0.3.0: Windows MediaFoundation Camera Controls

Professional Windows Controls: Full focus, exposure, white balance control
Hybrid Architecture: nokhwa capture + MediaFoundation controls
Thread-Safe COM: Proper Windows COM interface management

Forever maintainer: Michael A. Kuykendall
Promise: This will never become a paid product
Mission: Making desktop camera development effortless
