MP3 time measurement function

[hash6iron]

Hi @pschatzmann.

I don´t achieve to measure time of the MP3 playing file with PLAYER. Could you help me? The value always is zero.
Thanks in advance.

File* pFile = nullptr;
AudioSourceIdxSDMMC source("/","mp3",true);
...
pFile = (File*)source.selectStream("/test.mp3"); 
...
MP3DecoderHelix decoderMP3;
MetaDataFilterDecoder metadatafilter(decoderMP3);
MeasuringStream measureMP3(decoderMP3);
...
measureMP3.begin();
decoderMP3.begin();
player.setDecoder(metadatafilter);
player.begin();
...
while (playing)
{
        sMP3_begin = measureMP3.estimatedTotalTimeFor(pFile->size());
        Serial.println(sMP3_begin);
        player.copy();
}

You don't write any data to MeasuringStream!
You can use the setCallbackOnWrite() from the StreamCopy in the player, to feed it with data
