Python读取视频的两种方法（imageio和cv2）

import pylab
import imageio
#视频的绝对路径
filename = '/path/to/your/video.mp4'
#可以选择解码工具
vid = imageio.get_reader(filename, 'ffmpeg')
for im in enumerate(vid):
 #image的类型是mageio.core.util.Image可用下面这一注释行转换为arrary
 #image = skimage.img_as_float(im).astype(np.float32)
 fig = pylab.figure()
 fig.suptitle('image #{}'.format(num), fontsize=20)
 pylab.imshow(image)
pylab.show()

import numpy as np
import matplotlib.pyplot as plt
import pylab
import imageio
import skimage.io
import numpy as np 
import cv2 

cap = cv2.VideoCapture('/path/to/your/video.mp4') 

while(cap.isOpened()): 
 ret, frame = cap.read() 
 cv2.imshow('image', frame) 
 k = cv2.waitKey(20) 
 #q键退出
 if (k & 0xff == ord('q')): 
  break 

cap.release() 
cv2.destroyAllWindows()
