• Pyinstaller Hidden import 'ffmpeg-python' not found

  13 août 2024, par petunia rose

  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:\python38\lib\site-packages (0.2.0) 
Requirement already satisfied: future in c:\python38\lib\site-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:\Users\x\Desktop\input.mp4'
    output = 'C:\Users\x\Desktop\output.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:\Users\x\Desktop\input.mp4
2024-08-09 11:28:50,293 - ERROR - Video window -> ffmpeg_save_clip -> output file C:\Users\x\Desktop\ouput.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.

  


• ffmpeg - convert MP4 to Panasonic Lumix playable MJPEG [closed]

  21 août 2024, par Maro Natts

  I'm new to ffmpeg and ffprobe, I started using it to convert videos to show on 3DS and DSi for an art project.

  


  Now I want to show my own videos on a Panasonic LUMIX digicam (DMC-FT2)(JPN), but have had trouble getting the device to play the video.

  


  The digi takes videos in AVCHD Lite and Motion JPEG.

  


  I've tried online converting mp4 to the respective formats + changing file name, but the device only recognises that it's there — refuses to/can't play it.

  


  I also tried using this code to convert to MJPEG :
ffmpeg -i input.mp4 -c:v mjpeg -q:v 2 -an output.mjpeg

  


  But no luck ! Changed the filename to match the others, the camera recognised the file is there, but can't play it.

  


  So I used this code to get the information of a MJPEG video taken on the digi :
/opt/ffmpeg/ffprobe file.mp4 -show_streams  -select_streams v  -print_format json

  


  and got the following, is it possible to convert my own video (mp4) to these settings ? So that it can play on the device ? If so how ?

  


  Thanks !

  21 octobre 2024, par Daniel Crough — Analytics Tips

  When marketing decisions rely on website analytics, accuracy matters.
  However, Google Analytics and other analytics platforms sample data to
  generate reports, which can sometimes misrepresent the true data trends.
