How to stop I2S peripheral correctly

[accacca]

I am trying to create an RTSP server with video/audio streaming. When I close the client side and stop the I2S streaming, I get many error messages in the serial debug window.
What is the correct way to close the I2S peripheral?
My close function

Code: Select all

static esp_err_t app_audio_deinit()
{
  if (audio == NULL) return ESP_OK ;
  
  app_audio_g711_deinit() ; 
 ESP_LOGI (TAG, "esp_codec_dev_close start") ;
  esp_err_t ret = esp_codec_dev_close(audio->play_dev);
  //if (ret != ESP_OK) return ESP_FAIL ;
 ESP_LOGI (TAG, "esp_codec_dev_close end - play") ;
  ret = esp_codec_dev_close(audio->record_dev);
 // if (ret != ESP_OK) return ESP_FAIL ;
 ESP_LOGI (TAG, "esp_codec_dev_close end - rec") ;
 
  esp_codec_dev_delete(audio->play_dev);
  esp_codec_dev_delete(audio->record_dev);
  
  // Delete codec interface
  audio_codec_delete_codec_if(audio->in_codec_if);
  audio_codec_delete_codec_if(audio->out_codec_if);
  
  // Delete codec control interface
  audio_codec_delete_ctrl_if(audio->in_ctrl_if);
  audio_codec_delete_ctrl_if(audio->out_ctrl_if);
  audio_codec_delete_gpio_if(audio->gpio_if);
  
  // Delete codec data interface
  audio_codec_delete_data_if(audio->data_if);
  
  app_audio_i2s_deinit(I2S_NUM);
  app_audio_i2c_deinit(I2C_PORT);

  free(audio) ;
  audio = NULL ;

  return ESP_OK ;
}

I receive a lot of this errors:

You did NOT stop audio tasks before closing. You should stop RTSP audio reading / writing before shutting down I2S.
