That message means your code is trying to run an executable at /root/bin/ffmpeg, but that file doesn’t exist (FileNotFoundError).

What you should do:

• Check whether FFmpeg is installed and where it is

  • Run: which ffmpeg
  • Or in Python: import shutil; print(shutil.which("ffmpeg"))
  • If nothing prints, FFmpeg isn’t installed or isn’t in your PATH.

• Install FFmpeg (pick the command for your system)

  • Debian/Ubuntu: sudo apt-get update && sudo apt-get install -y ffmpeg
  • Red Hat/CentOS: sudo yum install -y ffmpeg
  • macOS: brew install ffmpeg
  • Windows: install from ffmpeg.org and add the bin folder to PATH

• If your app must use a specific path (/root/bin/ffmpeg), point it to the actual FFmpeg binary

  • Find the real path, e.g. /usr/bin/ffmpeg or /usr/local/bin/ffmpeg
  • Update your code or config to that path
  • Or set FFMPEG_BINARY in your environment to the real path:
    • export FFMPEG_BINARY=$(which ffmpeg)
  • Or create a symlink (if you really want /root/bin/ffmpeg to exist):
    • sudo mkdir -p /root/bin
    • sudo ln -s $(which ffmpeg) /root/bin/ffmpeg
  • Ensure it’s executable: sudo chmod +x /root/bin/ffmpeg

• If you’re in a container or CI environment

  • Ensure Dockerfile/CI image installs FFmpeg and that the path is in PATH or that you set the absolute path in your app

• Quick debugging snippet (in Python)

  • import shutil, subprocess
  • ffmpeg = shutil.which("ffmpeg")
  • if not ffmpeg: raise FileNotFoundError("FFmpeg not found. Install FFmpeg or fix PATH.")
  • subprocess.run([ffmpeg, "-version"], check=True)

If you can share a bit more context (the language/app you’re using, the stack, and where /root/bin/ffmpeg is coming from), I can give you more targeted steps.
