I installed ffmpeg and pydub successfully on my linux server.
And test with python environment ok.
But when i running my code on nginx + gunicorn + django, its alert with error /home/www/env/lib64/python3.8/site-packages/pydub/utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
Someone can help me ?
