1. 第一种方法

电脑下载安装ffmpeg

然后代码如下

python 复制代码

from moviepy.editor import VideoFileClip
import os
import ffmpeg


def convert_video_to_mp4(input_video_path, output_video_path):
    '''
    速度慢, CPU狂飙
    :param input_video_path:
    :param output_video_path:
    :return:
    '''
    video_clip = VideoFileClip(input_video_path)
    video_clip.write_videofile(output_video_path, codec='libx264', audio_codec='aac')


# 速度快
def covert_mkv_to_mp4(input_video_path, output_video_path):
    '''
    速度快,
    :param input_video_path:
    :param output_video_path:
    :return:
    '''
    ffmpeg.input(input_file).output(output_file, vcodec='copy', acodec='copy').run()

2 第二种方法

直接改后缀,就可以播放了...

这种方法真的是太简单了...

python 复制代码

filepath = '文件目录'
files = os.listdir(filepath)
for file in files:
    if file.find("mkv") > 0:
        oldname = os.path.join(filepath,file)
        file = file.replace('mkv','mp4')
        newname = os.path.join(filepath,file)
        os.rename(oldname,newname)
