ESP32 - SPIFFS was not declared in this scope

[ArkasDev]

I have already successfully played sounds on the esp8266. Now I wanted to develop the whole thing for the esp32, but the following error message occurs when compiling.

In file included from src/main.cpp:2:

I used a simple example:

main.cpp

#include <Arduino.h>
#include "AudioFileSourceSPIFFS.h"
#include "AudioGeneratorMP3.h"
#include "AudioOutputI2SNoDAC.h"

AudioGeneratorMP3 *mp3;
AudioFileSourceSPIFFS *file;
AudioOutputI2SNoDAC *out;
void setup()
{
  Serial.begin(115200);
  delay(1000);
  SPIFFS.begin();
  file = new AudioFileSourceSPIFFS("/jamonit.mp3");
  out = new AudioOutputI2SNoDAC();
  mp3 = new AudioGeneratorMP3();
  mp3->begin(file, out);
}

void loop()
{
  if (mp3->isRunning()) {
    if (!mp3->loop()) mp3->stop(); 
  } else {
    Serial.printf("MP3 done\n");
    delay(1000);
  }
}

With the follwing settings:

platformio.ini

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
monitor_speed = 115200

lib_deps = 
    ESP8266Audio

I have the same issue. Please help! Arduino Version 1.8.19 .

The error occurs since the SPIFFS library is missing. Please add the following at top of your code (below ):

include

Additionally, you may also need to add the "FS" dependency in the platformio.ini file:

lib_deps = FS

After adding #include to my main.cpp as @hizbi-github suggested, I still have the compile error. However after adding it to my AudioFileSourceSPIFFS.h file the problem solved!
