# Phase 2: Next-Generation Codecs Implementation
|
||||
|
||||
## 🎯 Overview
|
||||
|
||||
Successfully implemented comprehensive next-generation codec support (AV1, HEVC/H.265, HDR) that seamlessly integrates with the existing production-grade video processing infrastructure.
|
||||
|
||||
## 🚀 New Codec Capabilities
|
||||
|
||||
### AV1 Codec Support
|
||||
**Industry-Leading Compression**
|
||||
- **30% better compression** than H.264 at same quality
|
||||
- Two-pass encoding for optimal quality/size ratio
|
||||
- Single-pass mode for faster processing
|
||||
- Support for both MP4 and WebM containers
|
||||
|
||||
**Technical Implementation**
|
||||
```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
|
||||
|
||||
### HEVC/H.265 Support
|
||||
**Enhanced Compression**
|
||||
- **25% better compression** than H.264 at same quality
|
||||
- Hardware acceleration with NVIDIA NVENC
|
||||
- Automatic fallback to software encoding (libx265)
|
||||
- Production-ready performance optimizations
|
||||
|
||||
**Smart Hardware Detection**
|
||||
```python
|
||||
# Automatic hardware/software selection
|
||||
enable_hardware_acceleration=True
|
||||
# Uses hevc_nvenc when available, falls back to libx265
|
||||
```
|
||||
|
||||
### HDR Video Processing
|
||||
**High Dynamic Range Pipeline**
|
||||
- HDR10 standard support with metadata preservation
|
||||
- 10-bit encoding (yuv420p10le) for extended color range
|
||||
- BT.2020 color space and SMPTE 2084 transfer characteristics
|
||||
- Automatic HDR content detection and analysis
|
||||
|
||||
**HDR Capabilities**
|
||||
```python
|
||||
# HDR content analysis
|
||||
hdr_analysis = hdr_processor.analyze_hdr_content(video_path)
|
||||
# Returns: is_hdr, color_primaries, color_transfer, color_space
|
||||
|
||||
# HDR encoding with metadata
|
||||
hdr_processor.encode_hdr_hevc(video_path, output_dir, video_id, "hdr10")
|
||||
```
|
||||
|
||||
## 🏗️ Architecture Excellence
|
||||
|
||||
### Seamless Integration Pattern
|
||||
**Zero Breaking Changes**
|
||||
- Existing `VideoProcessor` API unchanged
|
||||
- All existing functionality preserved
|
||||
- New codecs added as optional formats
|
||||
- Backward compatibility maintained 100%
|
||||
|
||||
**Extension Points**
|
||||
```python
|
||||
# VideoEncoder class extended with new methods
|
||||
def _encode_av1_mp4(self, input_path, output_dir, video_id) -> Path
|
||||
def _encode_av1_webm(self, input_path, output_dir, video_id) -> Path
|
||||
def _encode_hevc_mp4(self, input_path, output_dir, video_id) -> Path
|
||||
```
|
||||
|
||||
### Advanced Encoder Architecture
|
||||
**Modular Design**
|
||||
- `AdvancedVideoEncoder` class for next-gen codecs
|
||||
- `HDRProcessor` class for HDR-specific operations
|
||||
- Clean separation from legacy encoder code
|
||||
- Shared quality preset system
|
||||
|
||||
**Quality Preset Integration**
|
||||
```python
|
||||
# Enhanced presets for advanced codecs
|
||||
presets = {
|
||||
"low": {"av1_crf": "35", "av1_cpu_used": "8", "bitrate_multiplier": "0.7"},
|
||||
"medium": {"av1_crf": "28", "av1_cpu_used": "6", "bitrate_multiplier": "0.8"},
|
||||
"high": {"av1_crf": "22", "av1_cpu_used": "4", "bitrate_multiplier": "0.9"},
|
||||
"ultra": {"av1_crf": "18", "av1_cpu_used": "2", "bitrate_multiplier": "1.0"},
|
||||
}
|
||||
```
|
||||

## 📊 Real-World Benefits
|
||||
|
||||
### Compression Efficiency
|
||||
| Codec | Container | Compression vs H.264 | Quality | Use Case |
|
||||
|-------|-----------|----------------------|---------|----------|
|
||||
| H.264 | MP4 | Baseline (100%) | Good | Universal compatibility |
|
||||
| HEVC | MP4 | ~25% smaller | Same | Modern devices |
|
||||
| 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)
|
||||
- **HDR Processing**: Recent FFmpeg with HDR metadata support
|
||||
|
||||
### Installation Verification
|
||||
```python
|
||||
from video_processor import HAS_ADVANCED_CODECS
|
||||
from video_processor.core.advanced_encoders import AdvancedVideoEncoder
|
||||
|
||||
# Check codec availability
|
||||
encoder = AdvancedVideoEncoder(config)
|
||||
av1_available = encoder._check_av1_support()
|
||||
hardware_hevc = encoder._check_hardware_hevc_support()
|
||||
```
|
||||
|
||||
## 📈 Performance Impact
|
||||
|
||||
### Encoding Speed
|
||||
- **AV1**: 3-5x slower than H.264 (configurable with av1_cpu_used)
|
||||
- **HEVC**: 1.5-2x slower than H.264 (hardware acceleration available)
|
||||
- **HDR**: Minimal overhead over standard HEVC
|
||||
|
||||
### File Size Benefits
|
||||
- **Storage savings**: 25-30% reduction in file sizes
|
||||
- **Bandwidth efficiency**: Significant streaming cost reduction
|
||||
- **Quality preservation**: Same or better visual quality
|
||||
|
||||
## 🚀 Future Extensions Ready
|
||||
|
||||
The advanced codec implementation provides excellent foundation for:
|
||||
- **Phase 3**: Streaming & Real-Time Processing
|
||||
- **AV1 SVT encoder**: Intel's faster AV1 implementation
|
||||
- **VP10/AV2**: Next-generation codecs
|
||||
- **Hardware AV1**: NVIDIA/Intel AV1 encoders
|
||||
|
||||
## 💡 Key Innovations
|
||||
|
||||
1. **Progressive Enhancement**: Advanced codecs enhance without breaking existing workflows
|
||||
2. **Quality-Aware Processing**: Intelligent preset selection based on codec characteristics
|
||||
3. **Hardware Optimization**: Automatic detection and utilization of hardware acceleration
|
||||
4. **Future-Proof Architecture**: Ready for emerging codec standards and streaming requirements
|
||||
|
||||
This implementation demonstrates how to **enhance production infrastructure** with cutting-edge codec technology while maintaining reliability, compatibility, and ease of use.
