Can I play mp4 audio?

[ahmadfathan]

Thank you for writing this awesome library. It's really useful for my project. So I develop a device using ESP32-S2. I stream mp4 file then play it using this library.

Currently, here is my implementation

  file_http = new AudioFileSourceHTTPStream();
  file_http->RegisterMetadataCB(MDCallback, (void *)"HTTP");
  if (file_http->open(URL)) {
    buff = new AudioFileSourceBuffer(file_http, preallocateBuffer, preallocateBufferSize);
    buff->RegisterStatusCB(StatusCallback, (void *)"buffer");
    aac = new AudioGeneratorAAC();
    out = new AudioOutputI2S();

    out->SetPinout(AMP_BCLK, AMP_WCLK, AMP_DOUT);
    aac->begin(buff, out);
  }

Unfortunately, I hear no output from my speaker. Is this library available for mp4? or was I doing wrong with the implementation?

Thank you
