moviepy 提取音频
#pip install MoviePy from moviepy.editor import * video = VideoFileClip('F://a.mp4') audio = video.audio audio.write_audiofile('F://dsa.mp3')
# 从本地载入视频myHolidays.mp4并截取00:00:50 - 00:00:60部分
clip = VideoFileClip("D://a.mp4").subclip(50, 60)
# 调低音频音量 (volume x 0.8)
clip = clip.volumex(0.8)
# 把最后生成的视频导出到文件内
clip.write_videofile("D://myHolidays_edited.webm")
合并音频和视频以及插入文字和图片

这里面会遇到问题:
你得下载安装ImageMagick
安装的时候,安装过程注意勾选Install development headers and libraries for C and C++ 。
修改moviepy包(\Lib\site-packages\moviepy\)中的config_defaults.py文件,修改为
FFMPEG_BINARY = os.getenv('FFMPEG_BINARY', 'ffmpeg-imageio')
IMAGEMAGICK_BINARY = os.getenv('IMAGEMAGICK_BINARY', 'auto-detect')
IMAGEMAGICK_BINARY = r"G:\ImageMagick-7.0.9-Q16\magick.exe"
安装包我已经存在百度云了 ImageMagick-7.0.9-22-Q16-x64-dll.exe
