相关疑难解决方法(0)

我正在尝试使用OpenCV 3.2(来自menpo conda频道)读取.mov文件的帧.我在Ubuntu 16.04 64位设置上使用Python 3.5.3通过Anaconda.

问题是,当我遇到cap.read()调用时,我从OpenCV得到以下错误消息,并且循环立即中断并捕获if num == 0条件.

这是我正在运行的全部代码:

import cv2
import numpy as np
import sys

f = sys.argv[1]
cap = cv2.VideoCapture(f)

frames = []
num = 0
while cap.isOpened():
    ret, frame = cap.read()
    if not ret: break
    gframe = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    frames.append(gframe)
    num += 1
    if num % 100 == 0:
        frames.append(gframe)
    if num % 1000 == 0:
        print(num)

if num == 0:
    print("Something went wrong: no frames found.")
    exit(0) …
