@LimJihu you can skip frames in the video dataloader here:

yolov5/utils/dataloaders.py

Lines 216 to 228 in 7cef03d

	if self.video_flag[self.count]:
	# Read video
	self.mode = 'video'
	ret_val, img0 = self.cap.read()
	while not ret_val:
	self.count += 1
	self.cap.release()
	if self.count == self.nf: # last video
	raise StopIteration
	path = self.files[self.count]
	self.new_video(path)
	ret_val, img0 = self.cap.read()

@glenn-jocher
thanks a lot, but i don't know how to operate this code.
i want detect 2000frames and left (not delete) 10000frames left.
my goal is detect 1 frame in every 6frames, and track left 5frames in every 6 frames.

any help?

@LimJihu I understand. You can achieve this by modifying the code in detect.py to skip frames in the video. You can use the frame index to determine when to skip frames. For example, you can modify your while loop to skip frames using the frame index. Additionally, for tracking the left frames, you can use a tracker like SORT or DeepSORT. For further assistance, you can refer to the Ultralytics Docs at https://docs.ultralytics.com/yolov5/ or ask for help in the YOLOv5 Discussions.
