python如何播放视频_python怎样播放视频？
python播放视频的方法：
1、使用OpenCV播放视频import numpy as np
import cv2 as cv
cap = cv.VideoCapture(vtest.avi)
while cap.isOpened():
ret, frame = cap.read()
# if frame is read correctly ret is True
if not ret:
print("Cant receive frame (stream end?). Exiting ...")
break
gray = cv.cvtColor(frame, cv.COLOR_BGR2GRAY)
cv.imshow(frame, gray)
if cv.waitKey(1) == ord(q):
break
cap.release()
cv.destroyAllWindows()
2、使用imageio库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()
