1、直接上干货！
import cv2
import numpy as np
#视频的路径
INPUT_FILE1 = 'E:/Download/BUG/Video/32.mp4'
INPUT_FILE2 = 'E:/Download/BUG/Video/33.mp4'
OUTPUT_FILE = 'E:/Download/BUG/Video/32_33.mp4'reader1 = cv2.VideoCapture(INPUT_FILE1)
reader2 = cv2.VideoCapture(INPUT_FILE2)
width = int(reader1.get(cv2.CAP_PROP_FRAME_WIDTH))
height = int(reader1.get(cv2.CAP_PROP_FRAME_HEIGHT))
#视频的输出格式
fourcc = cv2.VideoWriter_fourcc('m', 'p', '4', 'v')
print(width)
print(height)
writer = cv2.VideoWriter(OUTPUT_FILE,fourcc,30, # fps(width*2, height)) print(reader1.isOpened())
print(reader2.isOpened())
have_more_frame = Truewhile have_more_frame:have_more_frame, frame1 = reader1.read()_, frame2 = reader2.read()#frame1 = cv2.resize(frame1, (width, height))#frame2 = cv2.resize(frame2, (width, height))img = np.hstack((frame1, frame2))cv2.waitKey(1)writer.write(img)#释放所有的资源
writer.release()
reader1.release()
reader2.release()
cv2.destroyAllWindows()效果如下：
