Python语法如何实现MP4与GIF格式互转（附代码）

如何利用Python语法实现MP4与GIF格式互转，下面web建站小编给大家简单介绍一下具体实现代码！

代码如下：

import glob
import cv2
from PIL import Image

def convert_mp4_to_jpgs(input_file):
# 先将mp4文件的所有帧读取出保存为图片
video_capture = cv2.VideoCapture(input_file)
still_reading, image = video_capture.read()
frame_count = 0
while still_reading:
cv2.imwrite(f"output/frame_{frame_count:03d}.jpg", image)
# read next image
still_reading, image = video_capture.read()
frame_count += 1

def convert_images_to_gif(output_file):
# 读取目录下图片，用Pillow模块的Image和所有图片合并
# 成一张gif
images = glob.glob(f"output/*.jpg")
images.sort()
frames = [Image.open(image) for image in images]
frame_one = frames[0]
frame_one.save(output_file, format="GIF", append_images=frames[1:],
save_all=True, duration=40, loop=0)

def convert_mp4_to_gif(input_file, output_file):
convert_mp4_to_jpgs(input_file)
convert_images_to_gif(output_file)

if __name__ == "__main__":
convert_mp4_to_gif("demo.mp4", "output.gif")
