• Cannot find installation of real FFmpeg (which comes with ffprobe)

  29 mars 2023, par Asm Goni

  I was trying to fit a generator into a model and I got this error : 
AssertionError: Cannot find installation of real FFmpeg (which comes with ffprobe).

  



  I have looked over many of the solutions on GitHub and other questions on Stack Overflow but none of them worked for me.

  



  Here is one of the commands I ran :

  



  sudo add-apt-repository ppa:mc3man/trusty-media  
sudo apt-get update  
sudo apt-get install ffmpeg  
sudo apt-get install frei0r-plugins  


  



  pip list also indicates the presence of ffmpeg-1.4

  



  In addition, I tried force reinstalling and updating ffmpeg just in case any dependencies were not installed properly.

  



  I also set the skvideo's path for ffmpeg manually :

  



  skvideo.setFFmpegPath('/usr/local/lib/python3.6/dist-packages/ffmpeg/')


  



  This returns : /usr/local/lib/python3.6/dist-packages/skvideo/__init__.py:306: UserWarning: ffmpeg/ffprobe not found in path: /usr/local/lib/python3.6/dist-packages/ffmpeg/
  warnings.warn("ffmpeg/ffprobe not found in path: " + str(path), UserWarning)

  



  By the way, when I try installing, it also returns this error, I don't know what to do about this :

  



  Get:127 http://archive.ubuntu.com/ubuntu bionic/main amd64 vdpau-driver-all amd64 1.1.1-3ubuntu1 [4,674 B]
Fetched 60.4 MB in 7s (8,769 kB/s)
E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/w/wavpack/libwavpack1_5.1.0-2ubuntu1.1_amd64.deb  404  Not Found [IP: 91.189.88.149 80]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?


  



  I ran apt-get update --fix-missing and that didn't make anything better.

  



  Is there a solution to this ?

  


• Pydub installation and ffmpeg

  6 août 2021, par Lone Lunatic

  I was trying to get raw sound data out of a .mp3 file. Therefor I used the pydub module as stated here. I created a venv for this project and installed all necessary modules. But for some reason, pydub decided to give me an FileNotFoundError :

  



  (venv) Python-IT:LightsDev pythonit$ which python
/Users/pythonit/Documents/Programmieren/Python/LightsDev/venv/bin/python
(venv) Python-IT:LightsDev pythonit$ which pip3
/Users/pythonit/Documents/Programmieren/Python/LightsDev/venv/bin/pip3
(venv) Python-IT:LightsDev pythonit$ pip3 list 
------------- -------
ffmpeg        1.4
pip           18.1
pydub         0.23.0
pyee          5.0.0
python-ffmpeg 1.0.5
setuptools    39.0.1


  



  My exact code looks like that :

  



  from pydub import AudioSegment
sound = AudioSegment.from_mp3('test.mp3')
raw_data = sound._data
print(raw_data)


  



  and I get this error :

  



  FileNotFoundError: [Errno 2] No such file or directory: 'ffprobe': 'ffprobe'


  



  alongside this runtime warning :

  



  RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)


  



  I don't know if it is me, but some similar questions stating I should install ffmpeg or python-ffmpeg won't work. I can even import the ffmpeg module but nothing happens. I can work with ffmpeg and load files but using it with pydub won't work.

  



  EDIT : Today I changed to my windows machine and looked at the error in-depth. However I didn't manage to get it working, even with the solution provided in the comments (thank you though). I installed the ffmpeg binary as stated and i was able to get ffmpeg running in the shell, however not with pydub... I have no clue what is going on. I guess my mistake is very obvious and I am just not able to get it. Even not subprocess was able to solve this problem despite the fact, that I am able to use ffmpeg in shell. I even was able to convert the file using ffmpeg in shell...

  



   ffmpeg -i test.mp3 test.wav 
 > Output #0, wav, to 'test.wav':


  



  I think I am close to solve the problem myself anyways, but thank you anyways.

  


• ffmpeg installation : pkg-config can't find package (using Homebrew)

  21 septembre 2018, par Rico Picone

  I’m trying to install ffmpeg with Homebrew using the command

  brew install ffmpeg --with-freetype

  but get

  ERROR: freetype2 not found using pkg-config

  If I check /usr/local/lib/pkgconfig, the file freetype2.pc exists. In fact,

  pkg-config --list-all

  includes freetype2.

  I’ve tried reinstalling pkg-config and freetype with Homebrew, reinstalling git, updating Homebrew, upgrading Homebrew, uninstalling and reinstalling all Homebrew packages, etc.

  brew doctor gives mostly a bunch of warnings about dylibs, config scripts, and header files, probably from recently moving to a new machine and copying files. I thought the config scripts might be related, but they’re all pyenv shims.

  I’m ok with a nuclear fix, but I feel like I’ve tried every nuclear option I know other than creating an entirely new user account.
