```python
# New format options in ProcessorConfig
output_formats=["av1_mp4", "av1_webm"]
# Advanced AV1 settings
enable_av1_encoding=True
prefer_two_pass_av1=True
av1_cpu_used=6 # Speed vs quality (0=slowest/best, 8=fastest)
```
**Advanced Features**
- Row-based multithreading for parallel processing
- Tile-based encoding (2x2) for better parallelization
- Automatic encoder availability detection
- Quality-optimized CRF values per preset

| AV1 | MP4/WebM | ~30% smaller | Same | Future-proof streaming |
### Performance Optimizations
**AV1 Encoding**
- Configurable CPU usage (0-8 scale)
- Two-pass encoding for 15-20% better efficiency
- Tile-based parallelization for multi-core systems
**HEVC Acceleration**
- Hardware NVENC encoding when available
- Automatic software fallback ensures reliability
- Preset-based quality/speed optimization
## 🎛️ Configuration Options
### New ProcessorConfig Settings
```python
# Advanced codec control
enable_av1_encoding: bool = False
enable_hevc_encoding: bool = False
enable_hardware_acceleration: bool = True
# AV1-specific tuning
av1_cpu_used: int = 6 # 0-8 range (speed vs quality)
prefer_two_pass_av1: bool = True
# HDR processing
enable_hdr_processing: bool = False
# New output format options
output_formats: ["mp4", "webm", "ogv", "av1_mp4", "av1_webm", "hevc"]
```
### Usage Examples
```python
# AV1 for streaming
config = ProcessorConfig(
output_formats=["av1_webm", "mp4"], # AV1 + H.264 fallback
enable_av1_encoding=True,
quality_preset="high"
)
# HEVC for mobile
config = ProcessorConfig(
output_formats=["hevc"],
enable_hardware_acceleration=True,
quality_preset="medium"
)
# HDR content
config = ProcessorConfig(
output_formats=["hevc"],
enable_hdr_processing=True,
quality_preset="ultra"
)
```
## 🔧 Production Deployment
### Dependency Requirements
- **FFmpeg with AV1**: Requires libaom-av1 encoder
- **HEVC Support**: libx265 (software) + hardware encoders (optional)

s3_bucket="video-processing-bucket",
enable_lambda_processing=True
)
# Automatic scaling based on queue depth
processor = VideoProcessor(config)
```
### **📈 API Monetization**
```python
# REST API for video processing service
@app.post("/api/v1/process-video")
async def process_video_api(
file: UploadFile,
config: ProcessorConfig = Body(...)
):
result = await processor.process_video(file.path, output_dir)
return {
"video_id": result.video_id,
"processing_time": result.processing_time,
"formats_generated": list(result.encoded_files.keys()),
"is_360_video": result.is_360_video,
"quality_score": result.quality_analysis.overall_quality
}
```
