#8782 Video file selection required

This is because no video/audio file was actually added to the list before clicking Start, so the program detected that the input queue is empty and aborted.

Solution:

1. Click Select Video/Audio in the upper-left corner, browse to the video file in the file dialog, and double-click it to confirm (not just highlight it).
2. After selecting the file, check whether the file name appears in the list box in the upper-left corner; only then click Start Execution.
3. If you need to batch-process an entire folder, first check Folder, then click the select button and choose the folder that contains the videos.
4. If you just dragged the file in and the list is still empty, it means the drag-and-drop failed: use the button to select the file again. Also make sure the video name is short and has no emoji or special symbols, and that it is located in a shallow path (for example, D:/video1.mp4).
