• Cannot seem to work with mp3 files in pydub

  14 janvier 2023, par NegativePotato

  I have been trying to open mp3 files on pydub, I have ffmpeg in path and whatnot, but I get errors whenever I attempt to use pydub with mp3 files. Wav files work fine of course.
This is my code for testing purposes (copied directly from online) :

  


  from os import path
from pydub import AudioSegment

# files                                                                         
src = "Meet.mp3"
dst = "test.wav"

# convert wav to mp3                                                            
sound = AudioSegment.from_mp3(src)
sound.export(dst, format="wav")


  


  And this is my output for that code :

  Sorry if this ends up being obvious, I am new to using python. Thank you for the help !

  


• ffmpeg is not running from php exec() function, work from command line

  6 mars 2016, par Thanigaivelan

  When i run the ffmpeg command it is working from command line. but when i try from php exec(). it returns 127 error.

  my ffmpeg

  root@w1 [/]# which ffmpeg
  
  /root/bin/ffmpeg

  this is my code

  ffmpeg-y -i /home/castbox/public_html/IGVideo/upload/tamil/videos/testing/test_ig.mp4 -acodec libfdk_aac -ab 24k -ar 44100 -c:v libx264 -pix_fmt yuv420p -profile:v baseline -level 31 -b:v 200k -g 72 -f hls -hls_time 3 -hls_list_size 999 -s 426x240 /home/castbox/public_html/IGVideo/upload/tamil/videos/testing/test_ig-240-index.m3u8
  
  
  
  when i run this code in from command line it work fine. but when try to run from php exec i am getting failed, it returns 127.

  i had tried like this also

  /path/to/ffmpeg-y -i /home/castbox/public_html/IGVideo/upload/tamil/videos/testing/test_ig.mp4 -acodec libfdk_aac -ab 24k -ar 44100 -c:v libx264 -pix_fmt yuv420p -profile:v baseline -level 31 -b:v 200k -g 72 -f hls -hls_time 3 -hls_list_size 999 -s 426x240 /home/castbox/public_html/IGVideo/upload/tamil/videos/testing/test_ig-240-index.m3u8

  Where is my mistake ?
