Steps to Reproduce the Problem

be me and try to run from moviepy.video.io.ffmpeg_tools import ffmpeg_extract_subclip

ffmpeg is installed with apt and i can confirm its location in /usr/bin/. additionally ive also executed pip install imageio-ffmpeg in the python virtual environment and it is installed. ive logged platform.python_version() to confirm i was in the 3.8.0 venv. executing a plain interpreter terminal in the venv and trying to import it manually does not resault in an error. only during execution. the execution is in a flask application deployed with gunicorn and nginx.

Ok, try this before importing moviepy:

import os
os.environ["IMAGEIO_FFMPEG_EXE"] = "/usr/bin/ffmpeg"

For those on MAC, if you install ffmpeg with Homebrew, then the path is different, so the code become :

import os

os.environ["IMAGEIO_FFMPEG_EXE"] = "/opt/homebrew/Cellar/ffmpeg/5.1/bin/ffmpeg"
