• I can't play mp3 by iOS browser

  13 avril 2015, par SPnova

  I merge several files by ffmpeg :

  ffmpeg -i "concat:file1.mp3|file2.mp3" -acodec libmp3lame -metadata "title=Some Song"  c2.mp3

  But I can’t play this file by iOS browser (I use iPad 2 iOS 8). In my PC chrome this mp3 plays correctly.

  Where is the problem ?

• No such file or directory : 'ffprobe' : 'ffprobe'

  27 novembre 2023, par Jack McCumber

  I'm hoping someone can point me in the right direction. I'm currently trying to build a python GUI that plays clips of sounds from a specified file and allows the user to annotate it. All the research I've done has pointed my to using pydub. I'm using the following snippet :

  


  from pydub import AudioSegment
from pydub.playback import play

song = AudioSegment.from_wav("beepboop.mp3")
play(song)


  


  However, I'm currently getting the following error :

  I've downloaded both ffprobe and ffmpeg from the official website, extracted the files, and installed to usr/local/bin based on input I've read in other StackOverflow comments. When I run :

  


  print(os.environ['PATH'])


  


  I get :

  


  /usr/bin:/bin:/usr/sbin:/sbin


  


  Also, MacOSX won't let me manually drag the executable into /usr/bin or /usr/sbin. Nor will it let me copy it into the directory using :

  


  $ sudo cp ffmpeg /usr/bin


  


  When I use :

  


  pip3 install ffprobe-python


  


  I get :

  


  Requirement already satisfied: ffprobe-python in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (1.0.3)


  


  I'll add that when I try and use the "apt install" method, it barks at me and says my version of MacOSX isn't supported.

  


• Windows FFMPEG : Open Icecast Stream and output Metadata / "icy_metadata_packet" continuously

  6 octobre 2017, par Henry

  I managed to open a mp3 stream and save it to 6-second-files continuously.

  What I can’t find is a way to save the song titles to a file or output them.

  I came across "icy_metadata_packet" which should do exactly what I need but it is not well-documented as it seems. Can I use that option in the command line as an option or do I need a script of some sort to put this value somewhere ?
  If so, what’s the easiest way/language for a script like this ? (maybe a .bat file ?)

  Thanks in advance for your help !
