FileNotFoundError: [Errno 2] No such file or directory: 'ffmpeg'

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

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)

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

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

Help would be appreciated!

Like the warning says:

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

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

sudo apt-get install ffmpeg

Note: Tested on Ubuntu 18.04

Seems like you need ffmpeg, but

sudo apt-get install ffmpeg

does not work anymore. You can get ffmpeg by:

sudo add-apt-repository ppa:jon-severinsson/ffmpeg
sudo apt-get update
sudo apt-get install ffmpeg

If it won't let you install using sudo apt-get install libav-tools You can download the .deb from here:

wget http://launchpadlibrarian.net/339874908/libav-tools_3.3.4-2_all.deb

Then run sudo apt install ./libav-tools_3.3.4.2_all.deb

I've faced the same problem on my Ubuntu Ubuntu 18.04.3 LTS.

The issue is being solved by simply installing ffmpeg using:

sudo apt-get install ffmpeg

Instead of the popular Git-thread (https://github.com/lengstrom/fast-style-transfer/issues/129) suggestion of:

brew install ffmpeg

But you can always try both if the one doesn't work.
