• FFmpeg convert mp3 to pcm error "could not find codec parameters"

  20 février 2020, par Hanqing Wu

  When I am trying to convert a mp3 file to pcm using the following code, I repeatedly get the error message

  [mp3 @ 0x22cc420] Format mp3 detected only with low score of 1, misdetection possible!
  
  [mp3 @ 0x22cd260] Header missing
  
  [mp3 @ 0x22cc420] decoding for stream 0 failed
  
  [mp3 @ 0x22cc420] Could not find codec parameters for stream 0 (Audio: mp3, 0 channels, s16p): unspecified frame size
  
  Consider increasing the value for the 'analyzeduration' and 'probesize' options
  
  test.mp3: could not find codec parameters
  
  Input #0, mp3, from 'test.mp3':

  [abuffer @ 0x22cfaa0] Error setting option time_base to value 1/0.

  The mp3 file was converted from a video on Youtube.

• Pyinstaller "Failed to execute script pyi_rth_pkgres" and missing packages

  12 octobre 2023, par gurnben

  This is my first time posting a question here as most of my questions have already been answered by someone else ! I am working on a GUI application in python and am attempting to use pyinstaller to package it into a single folder and .exe for easier portability. Currently, I am using windows 10 and anaconda3 to manage my python packages. The application relies on tkinter, pillow, numpy, scikit-learn, opencv, ffmpeg, and matplotlib. The application is formatted with a main GUI.py file that creates objects of a number of other files (many of which are stored in a subfolder as this GUI is replacing a command line utility that served the same purpose). The issue I am running into (as you can see in the title) is that the .exe is throwing the error block :

  



  


  Traceback (most recent call last) :
 File "site-packages\PyInstaller\loader\rthooks\pyi_rth_pkgres.py", line 11, in 
 File "c :\users\gurnben\anaconda3\envs\opencv\lib\site-packages\PyInstaller\loader\pyimod03_importers.py", line 389, in load_module

 File "site-packages\setuptools-20.7.0-py3.5.egg\pkg_resources\extern__init__.py", line 60, in load_module
 ImportError : The 'packaging' package is required ; normally this is bundled with this package so if you get this warning, consult the packager of your distribution.
 Failed to execute script pyi_rth_pkgres

  


  



  When I look at the warn.txt it gives a massive list of missing packages including parts of some packages that are actually in the single folder package.
  
I have, however, successfully gotten it to recognize the dll files from opencv and it is not listed among the missing (nor is ffmpeg however I did not see any ffmpeg files in the folder). I had to pass in a custom path to get it to include the opencv files as they are not in anaconda at this time.

  



  Any hints or ideas for next troubleshooting steps ? I am overly greatful for all of the help you an offer and I can upload any code, files, etc. that would help you diagnose the issue. In the meantime I will continue searching for a solution myself !
