前言

本文主要分享一个可以将图片或者视频模糊化的工具代码。技术路线主要是使用FFmpeg滤镜。

环境依赖

ffmpeg环境部署，依赖包下载，给大家介绍一个调用ffmpeg比较好的库ffmpy。安装命令：


pip install ffmpy -i https://pypi.douban.com/simple

代码

不废话上代码。

import os
import uuid
from ffmpy import FFmpeg
 
 
def blur_image(image_path: str, output_dir: str, level=10):
    ext = os.path.basename(image_path).strip().split('.')[-1]
    if ext not in ['png', 'jpg']:
        raise Exception('fORMat error')
    ff = FFmpeg(
        inputs={
            '{}'.format(image_path): None}, outputs={
            os.path.join(
                output_dir, '{}.{}'.format(
                    uuid.uuid4(), ext)): '-filter_complex "boxblur={}:1:cr=0:ar=0"'.format(level)})
    print(ff.cmd)
    ff.run()
    return os.path.join(output_dir, '{}.{}'.format(uuid.uuid4(), ext))
 
 
def blur_video(video_path: str, output_dir: str, level=10):
    ext = os.path.basename(video_path).strip().split('.')[-1]
    if ext not in ['mp4', 'avi', 'flv']:
        raise Exception('format error')
    ff = FFmpeg(
        inputs={
            '{}'.format(video_path): None}, outputs={
            os.path.join(
                output_dir, '{}.{}'.format(
                    uuid.uuid4(), ext)): '-filter_complex "boxblur={}:1:cr=0:ar=0"'.format(level)})
    print(ff.cmd)
    ff.run()
    return os.path.join(output_dir, '{}.{}'.format(uuid.uuid4(), ext))

代码说明

1、blur_image和blur_video两个方法参数都是：图片/视频路径、输出文件夹目录、模糊等级。

2、模糊等级越高，模糊效果越大，默认10。

3、后缀校验按照需要加，我只是随便写了几种。

4、为了输出文件名不重复，用uuid作为文件名。

校验一下

下面是我准备的图片以及视频截图：

验证代码


if __name__ == '__main__':
    print(
        blur_image(
            'C:\\Users\\yi\\Desktop\\1.jpg',
            'C:\\Users\\yi\\Desktop\\'))
    print(
        blur_video(
            'C:\\Users\\yi\\Desktop\\2.mp4',
            'C:\\Users\\yi\\Desktop\\'))

执行结果
