# Déploiement Audio Classifier
|
||||||
|
|
||||||
|
## 🚀 Déploiement Autonome
|
||||||
|
|
||||||
|
Le système est **100% autonome** - aucune action manuelle requise ! Les modèles Essentia sont intégrés dans l'image Docker.
|
||||||
|
|
||||||
|
### Prérequis
|
||||||
|
|
||||||
|
- Docker + Docker Compose
|
||||||
|
- 2 GB RAM minimum
|
||||||
|
- Port 3000 (frontend) et 8001 (backend) disponibles
|
||||||
|
|
||||||
|
### Démarrage Rapide
|
||||||
|
|
||||||
|
1. **Cloner le projet** :
|
||||||
|
```bash
|
||||||
|
git clone <votre-repo>
|
||||||
|
cd Audio-Classifier
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Configurer le chemin audio** (optionnel) :
|
||||||
|
```bash
|
||||||
|
# Créer un fichier .env
|
||||||
|
echo "AUDIO_LIBRARY_PATH=/chemin/vers/votre/musique" > .env
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Démarrer** :
|
||||||
|
```bash
|
||||||
|
docker-compose up -d
|
||||||
|
```
|
||||||
|
|
||||||

## ❓ Troubleshooting
|
||||||
|
|
||||||
|
### Les modèles ne se chargent pas
|
||||||
|
```bash
|
||||||
|
# Vérifier que les modèles sont dans l'image
|
||||||
|
docker-compose exec backend ls -lh /app/models
|
||||||
|
|
||||||
|
# Devrait afficher 28 MB de modèles
|
||||||
|
```
|
||||||
|
|
||||||
|
### Le scan ne démarre pas
|
||||||
|
```bash
|
||||||
|
# Vérifier les permissions du dossier audio
|
||||||
|
docker-compose exec backend ls -la /audio
|
||||||
|
|
||||||
|
# Devrait être accessible en écriture
|
||||||
|
```
|
||||||
|
|
||||||
|
### Erreur de mémoire
|
||||||
|
```bash
|
||||||
|

|
||||||
|
# Docker Desktop > Settings > Resources > Memory : 4 GB minimum
|
||||||
|
```
|
||||||
|
|
||||||
|
### Port déjà utilisé
|
||||||
|
```bash
|
||||||
|
# Changer le port dans docker-compose.yml
|
||||||
|
services:
|
||||||
|
backend:
|
||||||
|
ports:
|
||||||
|
- "8002:8000" # Au lieu de 8001
|
||||||
|
```

|
# Tout en une commande !
|
||||||
|
git clone <repo> && \
|
||||||
|
cd Audio-Classifier && \
|
||||||
|
echo "AUDIO_LIBRARY_PATH=/mnt/musique" > .env && \
|
||||||
|
docker-compose up -d
|
||||||
|
|
||||||
|
# Attendre 30 secondes puis ouvrir http://serveur:3000
|
||||||
|
# Cliquer sur "Rescan" et c'est parti ! 🚀

# Configuration Transcodage & Optimisation
|
||||||
|
|
||||||
|
## 📋 Vue d'ensemble
|
||||||
|
|
||||||
|
Ce système implémente un transcodage automatique **MP3 128kbps** pour optimiser le streaming, tout en conservant les fichiers originaux pour le téléchargement.
|
||||||
|
|
||||||
|
## 🎯 Fonctionnalités
|
||||||
|
|
||||||
|
### 1. **Transcodage automatique**
|
||||||
|
- Tous les fichiers audio sont transcodés en **MP3 128kbps** lors du scan
|
||||||
|
- Fichiers optimisés stockés dans un dossier `transcoded/` à côté des originaux
|
||||||
|
- Compression ~70-90% selon le format source
|
||||||
|
|
||||||
|
### 2. **Pré-calcul des waveforms**
|
||||||
|
- Waveforms générées lors du scan (800 points)
|
||||||
|
- Stockées en JSON dans un dossier `waveforms/`
|
||||||
|
- Chargement instantané dans le player
|
||||||
|
|
||||||
|
### 3. **Double chemin en BDD**
|
||||||
|
- `filepath` : Fichier original (pour téléchargement)
|
||||||
|
- `stream_filepath` : MP3 128kbps (pour streaming)
|
||||||
|
- `waveform_filepath` : JSON pré-calculé
|
||||||
|
|
||||||
|
### 4. **Bouton Rescan dans l'UI**
|
||||||
|
- Header : bouton "Rescan" avec icône
|
||||||
|
- Statut en temps réel du scan
|
||||||
|
- Reload automatique après scan
|
||||||
|
|
||||||

```bash
|
||||||
|
docker-compose exec backend python -m src.cli.scanner /music
|
||||||
|
```
|
||||||
|
|
||||||
|
### Rescan via API
|
||||||
|
```bash
|
||||||
|
curl -X POST http://localhost:8000/api/library/scan
|
||||||
|
```
|
||||||
|
|
||||||
|
### Vérifier le statut
|
||||||
|
```bash
|
||||||
|
curl http://localhost:8000/api/library/scan/status
|
||||||
|
```
|
||||||
|
|
||||||
|
## 📊 Bénéfices
|
||||||
|
|
||||||
|
### Streaming
|
||||||
|
- **Temps de chargement réduit de 70-90%**
|
||||||
|
- Bande passante économisée
|
||||||
|
- Démarrage instantané de la lecture
|
||||||
|
|
||||||
|
### Waveform
|
||||||
|
- **Chargement instantané** (pas de génération à la volée)
|
||||||
|
- Pas de latence perceptible
|
||||||
|
|
||||||
|
### Espace disque
|
||||||
|
- MP3 128kbps : ~1 MB/min
|
||||||
|
- FLAC original : ~5-8 MB/min
|
||||||
|
- **Ratio: ~15-20% de l'original**
|
||||||
|
|
||||||
|
## 🛠️ Configuration
|
||||||
|
|
||||||
|
### Dépendances
|
||||||
|
- **FFmpeg** : Obligatoire pour le transcodage
|
||||||
|
- Déjà installé dans le Dockerfile
|
||||||
|
|
||||||
|
### Variables
|
||||||
|
Pas de configuration nécessaire. Les dossiers sont créés automatiquement :
|
||||||
|
- `transcoded/` : MP3 128kbps
|
||||||
|
- `waveforms/` : JSON
|
||||||
|
|
||||||
|
## 📝 Migration BDD
|
||||||
|
|
||||||
|
Migration appliquée : `003_add_stream_waveform_paths`
|
||||||
|
|
||||||
|
Nouveaux champs :
|
||||||
|
```sql
|
||||||
|
ALTER TABLE audio_tracks ADD COLUMN stream_filepath VARCHAR;
|
||||||
|
ALTER TABLE audio_tracks ADD COLUMN waveform_filepath VARCHAR;
|
||||||
|
CREATE INDEX idx_stream_filepath ON audio_tracks (stream_filepath);
|
||||||
|
```
|
||||||
|
|
||||||
|
## 🔍 Fallback
|
||||||
|
|
||||||
|
Si le fichier transcodé n'existe pas :
|
||||||
|
1. L'API stream utilise le fichier original
|
||||||
|
2. Aucune erreur pour l'utilisateur
|
||||||
|
3. Log warning côté serveur
|
||||||
|
|
||||||
|
## 🎵 Formats supportés
|
||||||
|
|
||||||
|
### Entrée
|
||||||
|
- MP3, WAV, FLAC, M4A, AAC, OGG, WMA
|
||||||
|
|
||||||
|
### Sortie streaming
|
||||||
|
- **MP3 128kbps** (toujours)
|
||||||
|
- Stéréo, 44.1kHz
|
||||||
|
- Codec: libmp3lame
|
||||||
|
|
||||||
|
## 📈 Performance
|
||||||
|
|
||||||
|
### Temps de traitement (par fichier)
|
||||||
|
- Analyse audio : ~5-10s
|
||||||
|
- Transcodage : ~2-5s (selon durée)
|
||||||
|
- Waveform : ~1-2s
|
||||||
|
- **Total : ~8-17s par fichier**
|
||||||
|
|
||||||
|
### Parallélisation future
|
||||||
|
Le code est prêt pour une parallélisation :
|
||||||
|
- `--workers` paramètre déjà prévu
|
||||||
|
- Nécessite refactoring du classifier (1 instance par worker)
|
||||||
|
|
||||||
|
## ✅ Checklist déploiement
|
||||||
|
|
||||||
|
- [x] Migration BDD appliquée
|
||||||
|
- [x] FFmpeg installé dans le container
|
||||||
|
- [x] Endpoint `/api/library/scan` fonctionnel
|
||||||
|
- [x] Bouton rescan dans l'UI
|
||||||
|
- [x] Streaming utilise MP3 transcodé
|
||||||
|
- [x] Waveform pré-calculée
|
||||||
|
- [ ] Tester avec de vrais fichiers
|
||||||
|
- [ ] Configurer cron/scheduler pour scan nocturne (optionnel)
|
||||||
|
|
||||||
|
## 🐛 Troubleshooting
|
||||||
|
|
||||||
|
### FFmpeg not found
|
||||||
|
```bash
|
||||||
|
# Dans le container
|
||||||
|
docker-compose exec backend ffmpeg -version
|
||||||
|
```
|
||||||
|
|
||||||
|
### Permissions
|
||||||
|
Les dossiers `transcoded/` et `waveforms/` doivent avoir les mêmes permissions que le dossier parent.
|
||||||
|
|
||||||
|
### Scan bloqué
|
||||||
|
```bash
|
||||||
|
# Vérifier le statut
|
||||||
|
curl http://localhost:8000/api/library/scan/status
|
||||||
|
|
||||||
|
