FFMPEG - [WinError 2] The system cannot find the file specified

I'm having an issue using the FFmpeg package.

Here's my code :

import ffmpeg_streaming

from ffmpeg_streaming import Formats, Bitrate, Representation, Size

_360p  = Representation(Size(640, 360), Bitrate(276 * 1024, 128 * 1024))
_480p  = Representation(Size(854, 480), Bitrate(750 * 1024, 192 * 1024))
_720p  = Representation(Size(1280, 720), Bitrate(2048 * 1024, 320 * 1024))

hls = video.hls(Formats.h264())
hls.representations(_360p, _480p, _720p)
hls.output('C:/Users/juled/Videos/testStreaming')

Quite simple as you can see, found it on the web.

And here's the error message I have:

Traceback (most recent call last):

FileNotFoundError: [WinError 2] The system cannot find the file specified

I've been checking every file quoted in the error message, but only one of them is "my" code, the others are FFmpeg and Python libraries codes.

I'm using IDLEX for Python 3.7.6 on Windows by the way.

I've tried to change some of the FFmpeg library code, especially where subprocess.Popen appears, by putting a shell=True in the parameters. New Error Message, different this time.

I've added FFmpeg to the PATH, no change.

I've reinstalled FFmpeg to be sure, but no change. I'm using this version: python-ffmpeg-video-streaming-0.1.14.

Do any of you have a solution I could try ?

Oh and a friend has the same issue on MAC.

This is a PATH environment variable issue. Based on this link, you could try:

import os
path = 'the path you want'
os.environ['PATH'] += ';'+path

to add the path to ffmpeg.exe to your system path (and also to check if your python instance is really looking at the correct path), and you can also change pythonpath,

import sys
sys.path.insert(0,'path/to/ffmpeg')

Note how these two are totally different. However, I find that the easiest way with programs like ffmpeg, which are self-contained executables, that you can just copy them to the working directory of your script and then run it, which is what solved your problem.
