Buffering not possible?

[devnull69]

I use your ESP32-Web-Radio, with an ESP8266, but it still works fine

Now, I wanted to add a buffer so that internet lag will not directly lead to a jumping MP3 stream. I did this by changing mp3buff to bufferptr with a length of 320, which I wanted to fill up with chunks of 32 bytes to be played by the player later.

I noticed the following:

// This works
void loop() {
      ...
      if (client.available() > 0)
      {
        uint8_t bytesread = client.read(bufferptr, 32);
        player.playChunk(bufferptr, bytesread);
      }
      ...
}

// This doesn't work
bool written = false;
void loop() {
      ...
      if (client.available() > 0 && !written)
      {
        uint8_t bytesread = client.read(bufferptr, 32);
        written = true;
      }
      if(written) {
        player.playChunk(bufferptr, 32);
        written = false;
      }
      ...
}

It should be the same, right? In both cases I let client.read fill up 32 bytes of the buffer at bufferptr before I play the chunk. In case 2 there is an Exception (9) though ...

Can you help me with this?
