Bug description

I'm currently testing DLC on our HPC and noticed a strange behavior between add_new_videos(extract_frames=True) and extract_frames().

When I try to extract frames via add_new_videos(extract_frames=True) I always get Frame extraction failed. Video files must be corrupted. but extract_frames() still works.
Switching between copy_videos=False and copy_videos=True has no effect.

Operating System

Operating System: Red Hat Enterprise Linux 8.6 (Ootpa)
CPE OS Name: cpe:/o:redhat:enterprise_linux:8::baseos
Kernel: Linux 4.18.0-372.26.1.el8_6.x86_64

DeepLabCut version

2.3.8

DeepLabCut mode

single animal

Device type

gpu

Steps To Reproduce

This causes the error:

import deeplabcut

config_file_path = '/gpfs/projects/acad/behavior/DLC_model/primary_DeepLabCut_model/LassanceLab-main-model-2023-09-14/config.yaml'

video_file_path = ["/gpfs/projects/acad/behavior/videos/2023-11-13_conspecific_odor_videos/2023-09-15_test videos/cluster_test_vid.mp4"]

VideoType = 'mp4'

deeplabcut.add_new_videos(
    config_file_path,
    video_file_path,
    copy_videos=False,
    coords=None,
    extract_frames=True,
)

If you now run deeplabcut.extract_frames(config_file_path, mode='automatic', algo='kmeans', userfeedback=False, crop=False) the extraction suddently works.
