• pydub cannot find ffprobe despite whatever solutions I tried

  18 avril 2020, par Wei

  This is a very similar question to this Pydub unable to locte ffprobe however after following the solution, it still doesn't work :|

  



  I have FFmpeg in path for environment variables as well.

  



  my current code is just a simple one to let myself familiarise with pydub.

  



  from pydub import AudioSegment
import os

directory = r"C:\Users\Wei's PC\Music\Files\Relaxing"

AudioSegment.converter = 'C:\\FFmpeg\\bin\\ffmpeg.exe'
AudioSegment.ffmpeg = "C:\\FFmpeg\\bin\\ffmpeg.exe"
AudioSegment.ffprobe = "C:\\FFmpeg\\bin\\ffprobe.exe"

os.chdir(directory)
file = AudioSegment.from_file(rf'{directory}\test.flac', 'flac')
file.export(f'River Flows in You.mp3', format = 'mp3')


  



  but I keep getting this error

• ffmpeg php installation - shared libraries not found [closed]

  7 juin 2012, par user1441923

  I have CENTOS 6.2 x86_64 standard on server57012

  Problem is I am stuck in installing the ffmpeg php extension for my video site. I have installed ffmpeg converter successfully but got stuck while installing the php extension. The output that I am getting when typing ./configure in the console is

  Its saying that ffmpeg shared libraries are missing. What steps are missing in my installation....??

• Why is this ffmpeg conversion turning up trash ?

  12 octobre 2015, par DigitalJedi805

  So, the company I work for still archives some of our data in Windows Media format.

  I’ve written a C# application that loops through all of our WMVs, and in the event that a corresponding MP4 doesn’t exist, it fires off ffmpeg to convert the file.

  What I’m running into, is a combination of problems.

  When I run the following into ffmpeg ( rough C# ) :

  "-i " + File.FullName + " -vf scale=720:480 -b:v 512k -bufsize 512k -vcodec libx264 -acodec aac -strict experimental " + OutputPath

  I end up with a file that cannot play in our browser based player ( JWPlayer ), and cannot play on my local system in Windows Media Player.

  Additionally, the file is larger than my WMV, and is larger than the file I output with [roughly] the same parameters in AVS Video Converter.

  Furthermore, the file details don’t show any values for the video properties - as in, when I right click and go to properties->details, under ’video’, there is a list of length, height, width, frame rate, and bitrate - they are all empty - when I would very much expect some data normally.

  Does anyone have any idea how I can make the conversion more straightforward, or what might be creating the problem in the first place ?

  I’ve tried running this without scaling or bitrate parameters, and added them as an attempt to resolve the more core problem - obviously to no avail.

  For everyone’s appeasement...
