• Why does OpenAI Whisper return "None" ?

  29 septembre 2024, par SHDDSFFDSDSAF

  I'm trying to transcribe an MP3 file using OpenAI’s Whisper model, but the transcriptions.create() method consistently returns None. I’ve tried different MP3 files, converted them to WAV, updated the OpenAI library, and added error handling, but I still can’t figure out the issue.

  


  Here’s my code :

  


  from openai import OpenAI

client = OpenAI(
    api_key="MYAPIKEY"
)

audio_file = open("speech.mp3", "rb")
transcript = client.audio.transcriptions.create(
    file=audio_file,
    model="whisper-1",
    response_format="verbose_json",
    timestamp_granularities=["segment"]
)

print(transcript)


  


  I’ve confirmed that :

  


  

  • The API key is valid.

  


  • I’m using OpenAI Python library version X.X.X.

  


  • I’ve tested both MP3 and WAV formats.

  


  • The MP3 file is valid (checked using ffmpeg).

  


  


  The response always returns None without any exceptions. Any ideas on what could be going wrong ?

  


• What does it mean for avcodec_find_decoder() to return 0 ? [duplicate]

  11 février 2019, par Lucas Zanella

  This question already has an answer here :

  • ffmpeg compilation problem : avcodec_find_decoder always returns null

  This part of my code

  m_pAVCodec = avcodec_find_decoder(AV_CODEC_ID_H264);

  is returning 0, which means it failed to find the codec.

  What does it mean for ffmpeg to not find a codec ? Is it something related with my system ? I need somehow to install the h264 codec ?

  I’m using Ubuntu

  UPDATE :

  By doing
  avcodec_register_all() ;

  before, it works. It’s kinda strange because av_register_all() was deprecated long ago and won’t even compile.

  What more needs to be registered ?

• PHP exec or shell_exec not returning process id (PID) on Windows Wamp

  17 mai 2013, par HoplaYann

  I am on windows 7, using a WampServer, and trying to use FFMPEG.

  The encoding works, but I can't get a process id back from either the exec()
  method nor the shell_exec() methods.

  This is my code :

  $cmd = C:\ffmpeg\bin\ffmpeg.exe -i "C:\...\4ch.wav"  -ar 44100 -ab 48000 -f mp3 -y "C:\...\enc_4ch.mp3"

  This what I was trying to do with shell_exec :

  shell_exec("nohup $cmd > /dev/null & echo $!");

  And with exec :

  exec("nohup " . $this->_command . " > /dev/null 2>/dev/null &") ; // returns null
  
  exec("nohup " . $this->_command . " > /dev/null 2>&1 &"); // also returns null 

  Please let me know what I do wrong, as I'd like later to use the following method to check if my process is still running :

  private function is_process_running($proccess_id) 
  
      { 
  
          exec("ps $proccess_id", $process_state);
  
          return (count($process_state) >= 2);
  
      }

  thank you in advace
