【Python音视频技术】用moviepy实现图文成片功能

今天上班的时候看到有人群里问图文成片怎么实现。临时给我提供一点写作的灵感，趁着下班写一篇。这里用到 python的moviepy库，之前文章介绍过。

大体思路：假定有4张图片，每张图片将在视频中展示2秒钟，并且图片会按照顺序循环播放，直到音频结束。

from moviepy.efrom moviepy.editor import ImageClip, AudioFileClip, concatenate_videoclips, CompositeVideoClip
from moviepy.audio.fx.all import audio_loop
from PIL import Image
import osdef resize_images(image_files, desired_size):resized_images = []for image_file in image_files:# 打开一张图片文件with Image.open(image_file) as img:# 调整图片大小到目标尺寸img = img.resize(desired_size, Image.ANTIALIAS)# 将调整后的图片保存到临时文件temp_file = f"temp_{os.path.basename(image_file)}"img.save(temp_file)resized_images.append(temp_file)return resized_imagesdef create_video_from_images(image_files, audio_file, output_file, fps=24, desired_size=(1280, 720)):# 将图片调整到目标尺寸resized_images = resize_images(image_files, desired_size)# 加载音频文件audio = AudioFileClip(audio_file)# 设置图片展示时长为2秒image_duration = 2# 创建单独的图片剪辑并设置展示时长clips = [ImageClip(img).set_duration(image_duration).set_fps(fps) for img in resized_images]# 将所有图片剪辑拼接成循环播放的一个视频剪辑video_clip = concatenate_videoclips(clips, method="compose").loop(duration=audio.duration)# 给视频剪辑设置音频final_video = video_clip.set_audio(audio)# 将结果写入输出文件final_video.write_videofile(output_file, codec="libx264", audio_codec="aac", fps=fps)# 清理临时文件for temp_file in resized_images:os.remove(temp_file)# demo：
image_files = ['image1.jpg', 'image2.jpg', 'image3.jpg', 'image4.jpg']  # 图片文件列表
audio_file = 'background_music.mp3'  # 音频文件
output_file = 'output_video.mp4'  # 输出视频文件create_video_from_images(image_files, audio_file, output_file)ditor import ImageClip, AudioFileClip, concatenate_videoclips, CompositeVideoClip
