Webcam stop working suddenly #6197
Description
YOLOv5 Component
Detection
Bug
after run python3 detect.py --source 0 --weights yolov5s.pt --conf 0.25
The webcam only capture ONE FRAME.

- Python 3.9
- Apple M1 Chip
Minimal Reproducible Example
After run python3 detect.py --source 0 --weights yolov5s.pt --conf 0.25
The webcam only capture ONE FRAME then stoped.
A 0 sec mp4 detect result can be generated in detect\exp* folder.
It also happens when I connect to an external camera via USB.
