Error opening 'audio_data/test.mp3' : file containers data in an unknown format

Attempting to run demo02 but running into this error,

Error opening 'audio_data/test.mp3' : file containers data in an unknown format

"raise RuntimeError(prefix + _ffi.string(err_str).decode('urf-8), 'replace')

I have reinstalled and ensured librosa was up to date and install ffmpeg just in case. Still no luck? Is this me or a bug?

warnings.warn('PySoundFile failed. Trying audioread instead.')

Seems like I didn't install ffmpeg properly.

The following worked - Centos 7

sudo yum install epel-release
sudo rpm -v --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
sudo yum install ffmpeg ffmpeg-devel

• librosa can't read mp3 files directly so it tries to use the audioread package.
• Audioread tries to utilise a number of different packages that may or may not be installed. One of those is ffmpeg.

FIX by intalling ffmpeg.

Ubuntu:
sudo apt install ffmpeg
