• 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.

  


• Encoding AV1 to h264 error : Assertion pkt failed at D :/code/ffmpeg/src/fftools/ffmpeg_dec.c:518 [closed]

  1er mars 2024, par KyonGiang

  I used below code to convert from AV1 to x264 mp4, and I got error message : "Assertion pkt failed at D :/code/ffmpeg/src/fftools/ffmpeg_dec.c:518"

  


  ffmpeg -i input.mp4 -c:v h264_nvenc -c:a copy output.mp4 


  


  

  • I'm using Windows 10 64b, Command Prompt, ffmpeg version 2024-01-20-git-6c4388b468-full_build-www.gyan.dev

  


  


  I removed h264_nvenc, Run as Administrator but the result is same.

  


  ffmpeg -i input.mp4 -c:v -c:a copy output.mp4

  


• FFmpeg : Specify pixel format for STD_IN input

  27 février 2024, par ShadowMagic896

  This is the current command :

  


  ffmpeg -i pipe:0 -pix_fmt yuv420p -f mp4 -vf "transpose=1" -f matroska pipe:1

  


  Essentially, it takes an MP4 file, rotates it 90 degrees, and converts it back to mtk and outputs it to STD_OUT.

  


  This is the error :

  I am running this via Python, this is the script :

  


      async def send_proc_pipe(self) -> bytes:

        command = f"ffmpeg -hide_banner -loglevel error -i pipe:0 -pix_fmt yuv420p -f mp4 -vf \"transpose=1\" -f matroska pipe:1"

        proc = await asyncio.create_subprocess_shell(
            cmd=command,
            stdin=asyncio.subprocess.PIPE,
            stdout=asyncio.subprocess.PIPE,
            stderr=asyncio.subprocess.PIPE
        )
        
        std_in = self.blob

        c_out, c_err = await proc.communicate(std_in)
        if c_err:
            logging.warning(c_err.decode("utf-8"))

        return c_out


  


  I'm not really use what else to try here. I've re-ordered the parameters and tried different pixel formats with no success.
