This PR includes a major cleanup and refactor of app_sadtalker.py, enhancing code readability, robustness, and UI interaction. Key changes:
✅ Logging and Error Handling:
Added structured logging (logging module) for better runtime traceability.
Clear error messages for missing files, invalid inputs, and failed initialization.
Validates presence of required checkpoints before running.
🎛️ Gradio UI Improvements:
Reorganized layout using gr.Blocks, Row, Column, and Tabs.
Real-time file upload feedback for image and audio inputs.
Integrated input validation before video generation.
Clear labeling and help text on settings.
🧠 Initialization Updates:
Defers SadTalker initialization until checkpoints and configs are verified.
Avoids crashing on invalid file paths.
🧹 General Cleanup:
Removed duplicate function definitions.
Restructured sadtalker_demo() for clarity and flow.
This refactor sets the stage for better extensibility and easier debugging in both standalone and webUI environments.
