progressStream

[niuteam]

I2SStream i2s;
MP3DecoderHelix decoder;
URLStream urlStream(urlStream, "audio/mp3");
ProgressStream progressStream(i2s);
AudioPlayer player(source, progressStream, decoder);

player.begin();
const char * len = urlStream.getReplyHeader("Content-Length");
progressStream.setSize(atoi(len));

void Audio::loop()
{
player.copy();
Serial.printf("[Audio] progress：%d\n", progressStream.percentage);
vTaskDelay(pdMS_TO_TICKS(1));
}

Based on the code above, the actual situation is that the progress is completely incorrect?

Yes, the output for the AudioPlayer is decoded PCM data that you want to measure against the encoded mp3 data!

So build your own output chain instead of the AudioPlayer or use the setCallbackOnWrite() from the AudioPlayer's StreamCopy
