Empty output file on "detect_video" function

[alexandoikon13]

When running the "detect_video" function as given in the tutorial, I define the input and output file but the latter is empty.

Would you be able to share the code that causes this issue? So is the output file missing completely or generated but has no frames?

[alexandoikon13]

The code I use is the following:
visualize.detect_video(model, './videos/video1.mp4', './videos/output1.avi', score_filter=0.8)
It outputs an empty file.

Could you check to make sure all the paths to files are correct? If a file is being written but is empty, then that probably means there's an issue when it comes to reading in the original video file.
