一.環境配置
https://ffmpeg.org/download.html#build-windows
#選擇對於系統
如果是windows直接訪問一下連接
https://github.com/BtbN/FFmpeg-Builds/releases
選擇xxx-shared.zip
https://github.com/BtbN/FFmpeg-Builds/releases/download/autobuild-2020-09-27-12-31/ffmpeg-N-99395-ga3a6b56200-win64-gpl-shared.zip
#再解壓把ffmpeg.exe所在路徑配置環境變量中
二.命令行執行代碼
ffmpeg -i 1.mp3 -f s16be -ar 16000 -ac 1 -acodec pcm_s16be 1.pcm
三.python執行代碼
from ffmpy import FFmpeg
#將mp3轉化沒pcm
ff = FFmpeg(inputs={r'd:\test\1.mp3':"-i"},
outputs={r'd:\test\1.pcm':"-f s16be -ar 16000 -ac 1 -acodec pcm_s16be"})
print(ff.cmd)
ff.run()
#將pcm轉化為mp3
ff1 = FFmpeg(inputs={r'd:\test\1.pcm':"-f s16be -ar 16000 -ac 1 -acodec pcm_s16be"},
outputs={r'd:\test\1.mp3':None})
print(ff1.cmd)
ff1.run()
四.參考文檔
