• Problem playing a sound with pydub Error : pydub.exceptions.CouldntDecodeError : Decoding failed. ffmpeg returned error code : 1

  28 mai 2020, par studioDKR

  I have a problem getting a file played in the browser with pydub. I think the function is working, but I just don't get the right file path to it, or something else is missing. Would love to get your help !

  



  I get the pydob error message : pydub.exceptions.CouldntDecodeError : Decoding failed. ffmpeg returned error code : 1

  



  Here is the error I get :

  This is the Flask route with the function I am writing.

  



  @app.route("/overview", methods=["GET", "POST"])
def overview():

    entries = []

    # Open a file
    path = app.config["FILE_UPLOADS"]

    with os.scandir(path) as dirs:
        for entry in dirs:
            entries.append(entry.name)

    if request.method == "POST":
        filename = request.form['filename']

        filepath = os.path.join(app.config["FILE_UPLOADS"], filename)

        # Play the sound
        sound = AudioSegment.from_file(filepath)
        play(sound)

        return render_template('overview.html', entries=entries)


  



  Here is the HTML template :

• Replace Special Characters In Batch-File Variable Feeding ffmpeg program

  14 janvier 2019, par whereswaller

  I am attempting to write a batch-file that leverages ffmpeg.exe to convert all files in a folder structure to mp3 format (specifically 128 KBps).

  My batch-file is presently unable to process filenames (constructed by concatenating the %_SOURCE% and %%~F variables) containing certain special characters generating the following errors :

  No such file or directory

  • … ellipsis sign
  • – en dash
  • — em dash
  • − minus sign

  Invalid argument

  • ‘ and ’ curved single quotation marks
  • “ and ” curved double quotation marks

  Invalid argument (yet sometimes passes depending on where symbol is in the filename, for example, seems to work if placed between the n and t of Dont in C:\Users\Test\Documents\Input\Peter Bjorn And John - I Know You Dont Love Me.mp3)

  • - hyphen
  • ! exclamation mark
  • ~ tilde
  • ' non-curved single quotation mark
  • = equals sign
  • + plus sign
  • % percentage sign
  • ( open bracket

  How can I modify my batch-file script so that the %%~F variable escapes these characters correctly ?

  Example current filename input : C:\Users\Test\Documents\Input\Peter Bjorn And John - I Know You Don't Love Me.mp3

  Example desired filename input : C:\Users\Test\Documents\Input\Peter Bjorn And John - I Know You Don"^'"t Love Me.mp3

  Script (see line beginning C:\ffmpeg\bin\ffmpeg.exe) :

  @echo off
  
  setlocal EnableExtensions DisableDelayedExpansion
  
  
  
  rem // Define constants here:
  
  set "_SOURCE=C:\Users\Test\Documents\Input" & rem // (absolute source path)
  
  set "_TARGET=C:\Users\Test\Documents\Output"  & rem // (absolute target path)
  
  set "_PATTERN=*.*" & rem // (pure file pattern for input files)
  
  set "_FILEEXT=.mp3"   & rem // (pure file extension of output files)
  
  
  
  pushd "%_TARGET%" || exit /B 1
  
  for /F "delims=" %%F in ('
  
      cd /D "%_SOURCE%" ^&^& ^(rem/ list but do not copy: ^
  
          ^& xcopy /L /S /Y /I ".\%_PATTERN%" "%_TARGET%" ^
  
          ^| find ".\" ^& rem/ remove summary line;
  
      ^)
  
  ') do (
  
      2> nul mkdir "%%~dpF."
  
  
  
      rem // Set up the correct `ffmpeg` command line here:
  
      set "FFREPORT=file=C\:\\Users\\Test\\Documents\\Output\\ffreport-%%~F.log:level=32"
  
      "C:\ffmpeg\bin\ffmpeg.exe" -report -n -i "%_SOURCE%\%%~F" -vn -c:a libmp3lame -b:a 128k "%%~dpnF%_FILEEXT%"
  
      if not errorlevel 1  if exist "%%~dpnF%_FILEEXT%" del /f /q "%_SOURCE%\%%~F"

• Projects from behind-the-scenes

  28 septembre 2018, par Jake Thornton

  Kia ora from the marketing team !

  Marketing team ? That’s right ! You haven’t heard from us in the past, but we’ve been working in the background to create a better experience for you, our dedicated Matomo community.

  Kia ora ? Well, that just means “hello” in Maori, we’re based in New Zealand you see.

  The Matomo marketing team has some really exciting projects in the works we wanted to share with you, but first, there’s someone I want to introduce :

  Meet Joselyn from the Matomo Marketing team

  Meet Joselyn, one half of the Matomo marketing team and our Digital Marketing and Communications Specialist. Joselyn has come on board to help us communicate more frequently and effectively as we continue our mission to be the #1 free open source analytics platform in the world. Please take it away, Joselyn !

  “Hi everyone ! The team here at Matomo have been doing an incredible job passionately driving the cause for user privacy and data ownership and uniting that with a love for digital analytics. It’s exciting being a part of a team unafraid to push on with their hearts on their sleeves and their values at the forefront of everything they do. I hope to bring to light all the fantastic things happening in our world of web analytics as well as across the globe.

  

  Our online world is fascinating when we think about what we can achieve with analytics, but there’s room to improve. We see newer technologies, but old ways of working which don’t take into account a person’s safety online. So we hope to champion a new future which looks set to be much more meaningful. Ensuring you get the best experience, but also feel protected with the knowledge that we get it. Your data and privacy isn’t for sale.

  I also hear you guys, the community, have followed Matomo since the beginning, which is wonderful ! I hope you’ll be able to join us as we grow and learn. We’ve got so many thrilling things to share with you. The highs, the lows and everything in between. Cheers !”

  Thanks Joselyn ! On top of working to engage the community and new users, Joselyn will also be keeping the rest of the Matomo team on our toes getting the inside scoop on what’s happening within the Development and Support teams ; as well as giving you behind-the-scenes access to what’s going on here at Matomo. We have a big vision and with so many things happening right now, we want to get you involved as much as possible.

  It may sound a bit clichéd but I’m saying it anyway – without your help, Matomo wouldn’t be here today.

  Help us choose a logo

  So first of all, we want you to say thank you and second we’d be delighted if you could help choose our new logo ! As you may already know, we changed our name from Piwik to Matomo at the start of the year. Though it was fun using a cool font (Aileron Heavy btw) as a quick fix for our name change, it was a temporary solution. The Matomo team has been involved in the direction of creating a new logo, but now we’re stumped ! We have three different concepts to choose from so please help us out !

  A new website for Matomo.org !

  Other exciting marketing projects include a new website design (yay !) – to everyone gasping nervously…don’t worry, nothing in what we offer is changing. We are and always will be a freely accessible open source analytics platform, just wanted to quickly clear the air on that one !

  We also have some video projects in the works to make the Matomo experience better for everyone and there are even rumours a brand video that tells the Matomo story is on the way ;)

  What next ? With Joselyn on board and loads of exciting projects happening, it won’t be long until you hear from us again, so keep an eye out for our next update as we reveal the winning Matomo logo.

  Be sure to follow us on Facebook, Twitter and Github – we promise to be more active than what we have been !
