Complete System Validation Script for Video Processor v0.4.0
|
|
|
|
This script validates that all four phases of the video processor are working correctly:
|
|
- Phase 1: AI-Powered Content Analysis
|
|
- Phase 2: Next-Generation Codecs & HDR
|
|
- Phase 3: Adaptive Streaming
|
|
- Phase 4: Complete 360° Video Processing
|
|
|
|
Run this to verify the complete system is operational.
