• 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.

  


• using mediamtx to stream video to browser [closed]

  18 octobre 2024, par Maximilian

  I am using rtsp to feed a video stream to mediamtx.

  


  I want to display the feed in a browser but always get some errors.

  


  I use the following to start mediamtx

  


  podman run --rm -it -e MTX_PROTOCOLS=tcp -e MTX_WEBRTCADDITIONALHOSTS=192.168.x.x -p 8554:8554 -p 1935:1935 -p 8888:8888 -p 8889:8889 -p 8890:8890/udp -p 8189:8189/udp docker.io/bluenviron/mediamtx


  


  I use this ffmpeg line to feed mediamtx :

  


  ffmpeg -i "rtsp://127.0.0.1:10000/test" -f rtsp rtsp://127.0.0.1:8554/feed


  


  I can view the feed with

  


  ffplay  rtsp://localhost:8554/feed


  


  ffplay says some things about my stream

  


  the mediamtx stream

  


  Input #0, rtsp, from 'rtsp://localhost:8554/feed':
  Metadata:
    title           : Session streamed with GStreamer

  Stream #0:0: Video: mpeg4 (Simple Profile), yuv420p, 320x240 [SAR 1:1 DAR 4:3], 30 tbr, 90k tbn, 30 tbc


  


  the source stream

  I use this html code try to display the video :

  


  
    



  


  mediamtx gives the following output when the browser tries to connect :

  


  2024/10/18 07:52:51 INF [RTSP] [session 7fe6a91a] created by 10.0.2.100:57542

  The stream is clearly h264... why is it complaining ?
