Visual Studio Code – Pyinstaller Hidden import 'ffmpeg-python' not found

Trying to convert Python scripts to exe with PyInstaller.

In my code, I use ffmpeg-python:

import ffmpeg
....
def ffmpeg_save_clip(self,output_video: str, clip_start: str, clip_end: str): 
  (ffmpeg 
   .input(self.file.get_videopath(), ) 
   .output(output_video, vcodec='copy', ss=clip_start, to=clip_end, acodec='copy') 
   .global_args('-y') 
   .run())

So Ii call PyInstaller from terminal with related flag:

pyinstaller --windowed --hidden-import "ffmpeg-python" --noconsole --icon=app.ico --name "app" main.py 

I checked also:

pip install ffmpeg-python 
Requirement already satisfied: ffmpeg-python in c:python38libsite-packages (0.2.0) 
Requirement already satisfied: future in c:python38libsite-packages (from ffmpeg-python) (0.18.3)

But I get from PyInstaller:

Hidden import 'ffmpeg-python' not found

App works in visual-studio, but when I run pyinstaller exe and try to save clip, it freeze without response.

Note: I also:

1. try to add ffmpeg.exe into root folder of pyinstaller app.

2. try to use .spec file with:

   binaries=[('C:\ffmpeg\bin\ffmpeg.exe', 'ffmpeg/),('C:\ffmpeg\bin\ffplay.exe','ffplay/'), ('C:\ffmpeg\bin\ffprobe.exe', 'ffprobe/')],

Nothing changes

UPDATE
Tank you @happy_code_egg, you explained me such a things.
I tried what you said and I don’t have error any more.

But I can’t make work ffmpeg anywhere on Pyinstaller exe.
I added a try/except block to isolate problem
(when I launch app on Visualstudio it works, but not when use exe).

block is (very symilar to past def):

def ffmpeg_save_clip(self,output_video: str, clip_start: str, clip_end: str):
    input = 'C:UsersxDesktopinput.mp4'
    output = 'C:UsersxDesktopoutput.mp4'
    try:
        (ffmpeg
        .input(input)
        .output(output, vcodec='copy', ss=clip_start, to=clip_end, acodec='copy')
        .global_args('-y')
        .run(capture_stdout=True))
    except Exception as e:
        self.logger.error('Video window -> ffmpeg_save_clip -> error ' + str(e))
        self.logger.error('Video window -> ffmpeg_save_clip -> input file: ' + input)
        self.logger.error('Video window -> ffmpeg_save_clip -> output file ' + output)
        raise ValueError(str(e))

Note: (input and output fixed are only as simple path examples)

When I open log I have:

2024-08-09 11:28:50,293 - ERROR - Video window -> ffmpeg_save_clip -> error [WinError 2] File not found error
2024-08-09 11:28:50,293 - ERROR - Video window -> ffmpeg_save_clip -> input file: C:UsersxDesktopinput.mp4
2024-08-09 11:28:50,293 - ERROR - Video window -> ffmpeg_save_clip -> output file C:UsersxDesktopouput.mp4

(I tried with ‘/’ and also ” to create path)
File paths are correct and, on Visualstudio, they can be processed by ffmpeg (no error), but the exe seems to not find (input or output)

I tried solution described here:
Python ffmpeg won’t accept path
(without effects)

I found also these discussions:

github ffmpeg-python issue1

github ffmpeg-python issue2

in both discussions seems to be a problem with ffmpeg + ffmpeg-python libs cohexistence.

I tried (as said) to uninstal both and reinstall ffmpeg-python,
but nothing change.

Note:
I’ve also three other warning during Pyinstaller:
(I write them only to complete context, but i think they have no repercussions on this problem.)

57283 ERROR: Hidden import 'fiona._shim' not found
57298 WARNING: Hidden import "fiona._shim" not found!
57392 WARNING: Hidden import "importlib_resources.trees" not found!

tried with:

--hidden-import fiona._shim --hidden-import fiona.schema

tried also with:

--add-data="fiona/*;fiona”

but warnings still remains.
