【问题描述】:
import numpy as np
import cv2
cap = cv2.VideoCapture(0)
count = 0
fourcc = cv2.VideoWriter_fourcc("drop.avi")
out = cv2.VideoWriter('drop.avi',fourcc, 20.0, (640,480))
while True:
# Capture frame-by-frame
ret, frame = cap.read()
# Our operations on the frame come here
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
name = "frame%d.jpg"%count # save frame as JPEG file
cv2.imwrite(name,frame)
# Display the resulting frame
cv2.imshow('frame',gray)
if cv2.waitKey(10):
break

我收到 TypeError: required argument 'c2' (pos 2) not found 运行代码时。我想运行一个视频文件,然后从视频帧中捕获图片。

你的fourcc错了。应该是:
cv2.VideoWriter_fourcc(*'XVID') -
