|
||||

|
||||
VOD_CACHE_TTL=3600
|
||||

|
||||
|
||||
# API Keys (Optional)

|
||||
|
||||
# Redis Databases
|
||||
REDIS_VOD_DB=4
|
||||
REDIS_METADATA_DB=3
|
||||
```
|
||||
|
||||
## Installation Instructions
|
||||
|
||||
1. **Apply the fixes**:
|
||||
```bash
|
||||
# Copy fixed files to app directory
|
||||
cp app/vod_metadata_service_fixed.py app/vod_metadata_service.py
|
||||
cp app/vod_directory_service_fixed.py app/vod_directory_service.py
|
||||
cp app/vod_api_fixed.py app/vod_api.py
|
||||
```
|
||||
|
||||
2. **Update dependencies**:
|
||||
```bash
|
||||
pip install aioredis redis ffmpeg-python
|
||||
```
|
||||
|
||||
3. **Update environment configuration**:
|
||||
```bash
|
||||
# Add to config/iptv.env
|
||||
echo "VOD_ENABLED=true" >> config/iptv.env
|
||||
echo "VOD_STORAGE_PATH=/media/vod" >> config/iptv.env
|
||||
echo "REDIS_VOD_DB=4" >> config/iptv.env
|
||||
echo "REDIS_METADATA_DB=3" >> config/iptv.env
|
||||
```
|
||||
|
||||
4. **Restart services**:
|
||||
```bash
|
||||
docker-compose -f docker/docker-compose.iptv.yml --env-file config/iptv.env restart iptv-backend
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
1. **Check VOD health**:
|
||||
```bash
|
||||
curl http://localhost:8000/api/vod/health
|
||||
```
|
||||
|
||||
2. **List content**:
|
||||
```bash
|
||||
curl -H "Authorization: Bearer YOUR_TOKEN" http://localhost:8000/api/vod/content
|
||||
```
|
||||
|
||||
3. **Scan directory** (Admin only):
|
||||
```bash
|
||||
curl -X POST -H "Authorization: Bearer ADMIN_TOKEN" \
|
||||
http://localhost:8000/api/vod/directories/scan/1
|
||||
```
|
||||
|
||||
## Performance Improvements
