  • 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 ?

    


  • ffmpeg + play video loop

    3 septembre 2013, par Javier Ramírez

    Does anyone know how to make a video using ffmpeg + Opengl play continuously ?. Because this is only played once

    tiempo = glfwGetTime();
    
duracion = 1.0/25.0; // 1 second / 25 fps
    

    
while(1){
    

    
...        
    

    
  if(glfwGetTime() > tiempo + duracion){
    
    if(av_read_frame(pFormatCtx,&packet) >= 0){
    
      if(packet.stream_index == 0){
    
        avcodec_decode_video2(pCodecCtx,pFrame,&frameFin,&packet);
    
        if(frameFin)sws_scale(img_convert_ctx,pFrame->data,pFrame->linesize,0,pCodecCtx->height,pFrameRGB->data,pFrameRGB->linesize);
    
      }
    
      av_free_packet(&packet);
    
    }
    
    tiempo += duracion;
    
  }
    

    
...
    

    
}

    I know av_read_frame function (...) returns 0 if the end of file. But how do I make the function again returns a value other than zero ? o How I can I make the video is constantly repeated ?

  • bytestream : Make get_bytes_left compatible with overread

    14 décembre 2019, par Andreas Rheinhardt
    bytestream : Make get_bytes_left compatible with overread

    bytestream2_get_bytes_left returns an unsigned int ; as a result,
    
it returns big positive numbers if an overread already happened,
    
making it unsuitable for scenarios where one wants to allow this
    
in a controlled way (because the buffer is actually padded so that
    
no segfaults can happen). So change it to return an ordinary int.
    

    Also, bytestream2_get_bytes_left_p has been modified in the same way.
