--save-crop from youtube error

🐛 Bug

Trying to save detection crops from youtube URL results in error.

To Reproduce (REQUIRED)

Input:

!python yolov5/detect.py --source https://www.youtube.com/watch?v=hZulqoCj6wM --save-crop --nosave

Output:

Traceback (most recent call last):
  File "yolov5/detect.py", line 181, in <module>
    detect(opt=opt)
  File "yolov5/detect.py", line 112, in detect
    save_one_box(xyxy, im0s, file=save_dir / 'crops' / names[c] / f'{p.stem}.jpg', BGR=True)
  File "E:\YOLOV5_Tests\yolov5\utils\general.py", line 669, in save_one_box
    clip_coords(xyxy, im.shape)
AttributeError: 'list' object has no attribute 'shape'

Expected behavior

Detection should crop from youtube.

Additional context

im0s is a list, im0s does not get processed in #Process Detections section in dectect.py. Using im0 instead, which is the ith element in im0s, crops the frame with b-box included. Passing im0s[i] instead of im0s in save_one_box seems to select the original image instance and avoids the error.
