This error occurs because the "Start Execution" action was triggered without selecting a valid audio/video file in the main interface (or without providing the --name parameter in CLI mode).
Solutions:
Click the 选择音频或视频 (Select audio/video) button in the first row of the main interface and choose one or more valid files (mp4/mkv/avi/mov/wav/mp3).
If using CLI mode, ensure the --name argument is passed with an absolute path, e.g. uv run cli.py --task vtv --name "/path/to/video.mp4" ....
If the file path contains non-English characters, spaces, or special symbols, rename it to a simple ASCII path (e.g., /Users/trillionareharsh/video.mp4) to avoid parsing issues.
