使用 imageio.ffmpeg.download() 时出现弃用错误

Question

我正在尝试使用 python Opencv 合并预先录制的视频。但我在导入时遇到错误。

"Traceback (most recent call last):
  File "video.py", line 4, in <module>
    from moviepy. editor import VideoFileClip,concatenate_videoclips 
  File "/home/pi/.virtualenvs/cv/lib/python3.5/site-packages/moviepy/editor.py", line 26, in <module>
    imageio.plugins.ffmpeg.download()
  File "/home/pi/.virtualenvs/cv/lib/python3.5/site-packages/imageio/plugins/ffmpeg.py", line 40, in download
    "imageio.ffmpeg.download() has been deprecated. "
RuntimeError: imageio.ffmpeg.download() has been deprecated. Use 'pip install imageio-ffmpeg' instead.'"

有人可以帮忙解决这个问题吗

这是代码：

import cv2 
import os 
import time 
from moviepy.editor import VideoFileClip,concatenate_videoclips 
def vidcapt():
    a = time.strftime("%H,%M,%S")
    cap = cv2.VideoCapture(0)
    fourcc = cv2.VideoWriter_fourcc(*'XVID')
    out = cv2.VideoWriter(a+'.avi', fourcc, 24.0, (640,480))
    t1 = time.time()
    while(cap.isOpened()):
            ret, frame = cap.read() 
            if ret == True:
                    out.write(frame)
                    cv2.imshow('frame',frame)
                    t2 = time.time()
                    time_diff = t2-t1
                    if time_diff >= 5:
                            break
            else:
                    break
    cap.release()
    out.release()
    cv2.destroyAllWindows()

while True:
        vidcapt()


clip1 = VideoFileClip("11,05,42.avi")
clip2 = VideoFileClip("11,05,47.avi").subclip(50,60)
final_clip = concatenate_videoclips([clip1,clip2])
final_clip.write_videofile("merged.avi")

试试这个：

sudo pip3 install imageio==2.4.1

希望能解决您的问题。
