FileNotFoundError:[错误2]没有这样的文件或目录:'ffmpeg' [英] FileNotFoundError: [Errno 2] No such file or directory: 'ffmpeg'

问题描述

我是python的新手，我正在使用pydub模块播放mp3曲目.

I'm new in python and i'm using pydub modules to play mp3 track.

这是我播放mp3的简单代码:

Here is my simple code to play mp3:

#Let's play some mp3 files using python!

from pydub import AudioSegment
from pydub.playback import play

song = AudioSegment.from_mp3("/media/rajendra/0C86E11786E10256/05_I_Like_It_Rough.mp3")
play(song)

当我运行该程序时，它说:

When i run this program, it says:

*/usr/bin/python3.4 /home/rajendra/PycharmProjects/pythonProject5/myProgram.py
/usr/local/lib/python3.4/dist-packages/pydub/utils.py:161: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work

请帮助我！我已经检查了所有路径，但无法正常工作.我目前正在使用Ubuntu.

Please help me! I've checked everything path but it's not working. I'm currently using Ubuntu.

我们将不胜感激！

推荐答案

就像警告说的那样:

Couldn't find ffplay or avplay - defaulting to ffplay, but may not work

您需要拥有ffplay或avplay；但是ffplay指的是ffmpeg，它在最新版本中无法在Ubuntu中安装.用apt-get安装libav-tools软件包:

You need to have either ffplay or avplay; however ffplay refers to ffmpeg which is not installable in Ubuntu in recent versions. Install the libav-tools package with apt-get:

sudo apt-get install libav-tools
