ValueError: zero-size array to reduction operation maximum which has no identity

[Saya47]

Hello! This is my first time using this script, it seems like it didn't finish the process completely and it didn't give me an output file, and I got an error at the end, here's the command I ran on Windows 10's CMD:
A:\jumpcutter-master/jumpcutter.py --input_file "\"C:\Users\S\Videos\2020-09-20 09-47-41 S1.mkv\"" --sounded_speed 1 --silent_speed 999 --frame_margin 2 --sample_rate 48 --frame_rate 60 --output_file S1.mp4 --frame_quality 5
