    The audio class that manage sounds contain a codec detector which say that the codec CODEC_ID_AAC is found for the two input :

    audioStreamBasicDesc_.mFormatFlags = 0;
    
switch (_audioCodecContext->codec_id) {
    
    case CODEC_ID_MP3:
    
         audioStreamBasicDesc_.mFormatID = kAudioFormatMPEGLayer3;
    
        break;
    
    case CODEC_ID_AAC:
    
         audioStreamBasicDesc_.mFormatID = kAudioFormatMPEG4AAC;
    
         audioStreamBasicDesc_.mFormatFlags = kMPEG4Object_AAC_Main;
    
        NSLog(@"audio format aac %s (%d) is  supported",  _audioCodecContext->codec_name, _audioCodecContext->codec_id);
    
        break;
    
}

    I see data going into the buffer but i hear nothing. It's maybe audioStreamBasicDesc_ which has wrong settings but i can't find what.

    Is it possible that it's not the same AAC codec ?

    Has someone experienced the same issue ?

    Any help are welcome, i'm on this problem since some days now.

    Edit :
    I have found a error that i had not before, i don't know how to resolve it. If i change audioStreamBasicDesc.mFramesPerPacket to 0 or divided by 2, the error message dissapear.

    AudioConverterNew returned 'fmt?'
    
Prime failed ('fmt?'); will stop (72000/0 frames)

  • Rails : Encoder error when converting video using FFMPEG on Heroku

    2 janvier 2013, par andmcgregor

    I'm trying to upload a video and convert the file to mp4 and reduce the file size using the paperclip-ffmpeg and paperclip gems. Everything works fine running a local server and I'm only getting this problem on heroku. I have ffmpeg installed in vendor/ffmpeg/ (I followed these steps : https://gist.github.com/3963576). Here is the code I've got and the error I'm getting :

    models/video.rb :

  has_attached_file :video , :styles => {

        :convert_options => { :output => { :vcodec => 'libx264',
    
        :b => '1000k', :bt => '200k',

  }, :processors => [:ffmpeg]

end

    when I run heroku logs :
