#6957 Video file selection required

The error "Video file selection required" appears because you clicked Start Execution without first selecting a video or audio file in the main interface.

Solution:

1. At the top-left of the main interface, click the 「Select audio or video」 button.
2. Choose the file(s) you want to process. Supported formats include mp4/mkv/avi/mov/wav/mp3.
3. After the file appears in the list, click Start Execution again.

Additional checks:

• Make sure the file actually exists at the path you selected and is not corrupted.
• Ensure the file path contains no special characters (spaces are acceptable in the parent folder, but if the error persists, try moving the video to a simple path like D:/video.mp4).
• If you are trying to process a folder, make sure the 「文件夹」 checkbox is correctly toggled and the folder contains valid media files.

If the error still occurs after selecting a valid file, please provide the latest log from the logs/ folder (copy about 30 lines of error details) for further analysis.
