Esp32 web radio, transmit to bluetooth speaker / Compilation errors

[PowerTcX]

Hi, first thank U for a great audio library for esp32.
I'm trying to make an esp32 web radio player, so esp32 transmit url audio to a bluetooth speaker.
I Tried make it from examples, but always got compilation errors.
I found that WiFi and Bluetooth coexistence is problematic, so just play .mp3 files from SD card will be fine.
To solve WiFi/Bluetooth coexistence i planning to use external BT like this -
Bluetooth Module Audio Transmitter

#define USE_HELIX 
#define USE_A2DP

#include "AudioTools.h"
#include "BluetoothA2DPSource.h"
#include "AudioCodecs/CodecMP3Helix.h"

using namespace audio_tools;
BluetoothA2DPSource a2dp_source;  

const char *urls[] = {
  "http://centralcharts.ice.infomaniak.ch/centralcharts-128.mp3",
  "http://centraljazz.ice.infomaniak.ch/centraljazz-128.mp3",
  "http://centralrock.ice.infomaniak.ch/centralrock-128.mp3",
  "http://centralcountry.ice.infomaniak.ch/centralcountry-128.mp3",
  "http://centralfunk.ice.infomaniak.ch/centralfunk-128.mp3"
};
const char *wifi = "Wifi";
const char *password = "PassWord";

URLStream urlStream(wifi, password);
AudioSourceURL source(urlStream, urls, "audio/mp3");
//A2DPStream out = A2DPStream::instance();  // A2DP output - A2DPStream is a singleton!
MP3DecoderHelix decoder;
AudioPlayer player(source, AudioSourceURL, decoder);


void setup() {
  Serial.begin(115200);
  AudioLogger::instance().begin(Serial, AudioLogger::Warning);

  // setup output - We send the output via A2DP to a "LEXON MINO L" Bluetooth Speaker
  a2dp_source.start("ATH-M50xBT", AudioPlayer);  
  a2dp_source.set_volume(30);

}

void loop() {
  player.copy();
}

But I think you should not get any compilation errors. Are you sure that you have installed all necessary libraries ?

[PowerTcX]

All necessary libraries in correct place.

Still get a errors -

  out.begin(cfg);

  // setup player
  player.setVolume(0.1);
  player.begin();

}

  player.copy();
}

Where did you get this example from ? It uses old style obsolete syntax:

• remove the USE statements
• add the missing include files

Please use the examples from the examples directory only...
The audio sources can be found in AudioLibs

[PowerTcX]

Example from -
https://www.pschatzmann.ch/home/2021/11/02/streaming-mp3-files-to-a-bluetooth-speaker/

[pschatzmann]

Blogs are using the syntax that was valid when the blog was written.
Please use the updated example from Github

Thank U, i found a correct example.

I converted mp3 music to 128kbps, music is playing but sound is not continous, like - 0.5s play, 0.5s silence.
