Correct AudioMessage template

How to create a correct to fill fields AudioMessage protocol ?
It showing in Web Wa but doesn't appear on Mobile App.

Here's my code :

Show code

func NewAudio(data []byte, seconds int, ctx *waProto.ContextInfo, client *whatsmeow.Client) (*waProto.AudioMessage, error) {

  var mimetype = http.DetectContentType(data)
  log.Println(mimetype)

  var ptt = strings.Contains(mimetype, "ogg")
  if ptt {
    mimetype = "audio/ogg"
  }

  if up, err := client.Upload(context.Background(), data, whatsmeow.MediaAudio); err != nil {
    return nil, err
  } else {
    var message = &waProto.AudioMessage{
      Url:               &up.URL,
      Mimetype:          &mimetype,
      FileSha256:        up.FileSHA256,
      FileLength:        &up.FileLength,
      Seconds:           proto.Uint32(uint32(seconds)),
      Ptt:               &ptt,
      MediaKey:          up.MediaKey,
      FileEncSha256:     up.FileEncSHA256,
      DirectPath:        &up.DirectPath,
      ContextInfo:       ctx,
      StreamingSidecar:  []byte{}, // Didn't know what is this
      Waveform:          []byte{}, // I can't provide this because so many task should to do to create waveform of audio format
    }

    switch mimetype {
    case "audio/mpeg":
      {
        var decoder = mp3.NewDecoder(bytes.NewReader(data))
        var frame mp3.Frame
        var total_sec float64
        for {
          if err := decoder.Decode(&frame, nil); err != nil {
            if err == io.EOF {
              break
            }
            log.Println(err)
          } else {

            total_sec += frame.Duration().Seconds()
          }
        }

        if total_sec > 0 {
          message.Seconds = proto.Uint32(uint32(total_sec))
        }
      }
    case "audio/wave":
      {
        var decoder = wav.NewDecoder(bytes.NewReader(data))
        if total_sec, err := decoder.Duration(); err == nil {
          message.Seconds = proto.Uint32(uint32(total_sec))
        }
      }

    }

    return message, err
  }

}

Correctly shows in web and on mobile

Whats kind of your audio type is ?
Opus/ogg or mpeg/mp3 ?

mpeg/mp3

[mamur-rezeki]

Yes, I'm also have no problem with mp3 file. Bc that always working with the mimetype just only audio/mpeg.

But for ogg file maybe that didn't enough just with mimetype audio/ogg. That i thought need to fullfil the fields of audio message protocol.

Recently I've been testing to change the mimetype of ogg file to audio/ogg; codecs=opus for opus codecs it's working so far.

[mamur-rezeki]

On Web App, they're show correctly.

On mobile, the audio/ogg didn't showing until i add specific codec name audio/ogg; codecs=opus.

Btw, http.DetectContentType always return application/ogg, I'd change it directly to the correct acceptable mimetype. 😅
