opencv------图片转化为视频

图片转化为视频：

步骤：
1.读取该路径下的图片
2.循环遍历，读取该图片
3.保存到视频里面（videocapture）

import cv2
import numpy as np
import glob
import os

file_path=glob.glob(os.path.join(r"E:\deeplearning\cv4_1\day05\traffic_lights_dataset\receive_img","*.jpg"))
print(file_path)

video_path="traffic_lights1.mp4"
fps=1
# frame = cv2.imdecode(np.fromfile(file_path[0]), -1)
frame=cv2.imread(file_path[0])
video_writer=cv2.VideoWriter(video_path,cv2.VideoWriter_fourcc(*"mp4v"),fps,(frame.shape[0],frame.shape[1]))

for file in file_path:
    img=cv2.imdecode(buf=np.fromfile(file,dtype=np.int8),flags=cv2.IMREAD_COLOR)
    cv2.imshow("img",img)
    video_writer.write(img)
    if cv2.waitKey(1) & 0xff==ord("q"):
        break

video_writer.release()
