hi,

I use the BluetoothA2DPSink library to stream music via Bluetooth. that works so far.

I have track information such as title and artist displayed on a TFT display.
That works too.

Now I would like to display the album cover on the TFT. I've researched whether this information exists about the metadata callback, but I can't get any further with the implementation

Does anyone have a code example to read the data for the image file (for example jpeg) into an array via a decoder and display it on the TFT?

here is my previous code:

Code: Select all

void avrc_metadata_callback(uint8_t id, const uint8_t *text){
  
  Serial.printf("==> AVRC metadata rsp: attribute id 0x%x, %s\n", id, text);

  if (id == ESP_AVRC_MD_ATTR_PLAYING_TIME){
    uint32_t playtime = String((char *)text).toInt();
    Serial.printf("==> Playing time is %d ms (%d seconds)\n", playtime, (int)round(playtime / 1000.0));
    PlTi = (int)round(playtime / 1000.0);
  }
  if (id == 0x1){
    tTitel = String((char *)text);
  }

  if (id == 0x2){
    tArtist = String((char *)text);
  }
  TRA = TNAME + " - " + TART;
  pTrack(tTitel, tArtist, cPS);
}

and here i setup the callback

Code: Select all


a2dp_sink.set_avrc_metadata_attribute_mask(ESP_AVRC_MD_ATTR_TITLE | ESP_AVRC_MD_ATTR_ARTIST | ESP_AVRC_MD_ATTR_ALBUM | ESP_AVRC_MD_ATTR_PLAYING_TIME);
  a2dp_sink.set_avrc_metadata_callback(avrc_metadata_callback);

I am grateful for any help

many thanks in advance
