Add build_executables.py script and requirements.txt

- Introduced a new script `build_executables.py` for building platform-specific executables using PyInstaller. - Implemented functions for cleaning build directories, handling retries on directory removal, and determining executable names based on the operating system. - Added `requirements.txt` to specify dependencies: PyInstaller, tk, pillow, and packaging. - Updated README.md to reflect recent changes and improvements in the application. new featues: ## Recent Updates: Multi-File Processing Support The GUI application has been enhanced with batch processing capabilities. Here are the key improvements: ### New Features 1. **Multiple File Selection** - Users can now select multiple files simultaneously - First selected file is displayed in the UI for reference 2. **Simplified Output Handling** - Single output directory selection for all files - Automatic file naming with "_injected" suffix 3. **Batch Processing** - Sequential processing of all selected files - Robust error handling: individual failures don't stop the batch - Progress tracking with status messages ### Technical Implementation The changes were implemented in `spatialmedia/gui.py`: ```python # Enable multiple file selection self.open_options["multiple"] = True # Process multiple files for input_file in self.all_files: output_file = os.path.join( os.path.dirname(self.save_file), f"{split_filename[0]}_injected{split_filename[1]}" ) metadata_utils.inject_metadata(input_file, output_file, metadata, console.append) ``` These updates significantly improve workflow efficiency when processing multiple videos.
