• 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.

  


• MoviePy Is Able To Print Video Duration But When Performing Edit It Cannot Find Duration ? | Python

  10 avril 2021, par PythonProgrammer

  I have been troubled by this issue when I am making a video downloader.
The Code Below :

  


      videoclip = VideoFileClip(fr'{directory}\audio\{yt.title}.mp4')

    duration = videoclip.duration

    print(duration)

    audioclip = videoclip.audio
    audioclip.write_audiofile(fr"{directory}\{yt.title}.mp3")
    audioclip.close()
    videoclip.close()


  


  Output :

  


  145
MoviePy error: failed to read the duration of file C:\Users\achut\Desktop\Movies\audio\Winning With Half A Heart | Minecraft Skywars.mp4.
Here are the file infos returned by ffmpeg:

  For some odd reason it is able to print the video duration but apparently cannot find it when I am trying to save the audio from the video as a separate file.

  


  Thanks for the help ! I am using latest version of moviepy and its dependencies, I just installed it today.

  


• Official Debian Package for Piwik now available

  15 avril 2014, par Matthieu Aubry — Community, Meta

  We are excited to announce the release of Piwik package for Debian based linux distributions !

  There are several ways to use Piwik :
  
   Download and upload to your server
  
   or use 1-click Piwik installers
  
   or use Microsoft web app gallery
  
   or buy Piwik Cloud
  
   or as of today, you may get Piwik using our Debian package

  What are the benefits of using Debian package over direct download ?

  For some system administrators, using Debian package is an easier alternative than directly downloading the code. It allows sysadmins to deploy Piwik within seconds using “apt-get install piwik -V”.

  How do I install Piwik using official debian package ?

  The package supports Apache and Nginx web servers. Read the documentation at debian.piwik.org.

  Do I have to use the Debian Package on my debian system ?

  No, you may still want to use Piwik using the direct download approach. You can keep Piwik upgraded quite easily using the popular 1-click automatic update.

  How do I report a bug or feedback ?

  Create a ticket on the Github project Issues page.

  Will the debian repository be maintained in the future ?

  Yes, Aurélien Requiem (github) along with the Piwik team are committed to maintain the Debian Piwik repository in the future.

  Thank you to Aurélien for his great work on preparing, testing, and maintaining the Debian repository for Piwik.
