Hi,
I am having some trouble in my windows 10 pc to compile this code .Whenever i am doing make , i am getting below result .Which i have no clue .How can i resolve it . Thank you in advance .

make[1]: *** No rule to make target 'C:/msys32/home/ravi_/esp/esp-idf/examples/get-started/ESP32_MP3_Decoder/components/MerusAudio/MerusAudio.c', needed by 'MerusAudio.o'. Stop.

Hi MrBuddyCasino,
Would it be possible to read broadcasted mp3 data from UDP port?
I have 80 devices with ESP32 modules in single wifi network, I would like to setup a Linux server that will stream 16 channels to broadcast address on different port and I would like ESP modules to connect to one of 16 channels. The idea is to have lower wifi usage (16 UDP streams) instead of 80 TCP/IP simultaneous connections.
Best Regards
Marek

is it not possible to use both?
switch bluetooth on/off with an gpio toogle or web command?

is there any way to use this with the arduino ide?

Hi,
I want to read the mp3 file from sd card, decode it and output throuhg built-in DAC, but it occured an error(MAD_ERROR_LOSTSYNC ).
following is my code that calling funcion:
static void play_mp3_file(void *vparameter)
{
web_radio_t *radio_conf = vparameter;

char mp3_data[1024];//[4096];


player_t *player_config = radio_conf->player_config;

int ret;
int i;

ESP_LOGI(TAG,"play_mp3_file task\r\n");
FILE* f = fopen("/sdcard/ghsy.mp3","r");
if (f == NULL) {
ESP_LOGI(TAG,"Failed to open file for reading.\r\n");
vTaskDelete(NULL);
}

player_config->media_stream->content_type = AUDIO_MPEG;
player_config->media_stream->eof = false;

player_config->command = CMD_START;
player_config->buffer_pref = BUF_PREF_FAST;//BUF_PREF_SAFE;//

audio_player_start(player_config); 
while(1)
{
	ret=fread(mp3_data,1,sizeof(mp3_data),f);
	
	if(ret <= 0)
	{
		ESP_LOGI(TAG,"play mp3 read file error.\r\n");
		break;
	}

ESP_LOGI(TAG,"play_mp3_file read data succ\r\n");
while( audio_stream_consumer(mp3_data, sizeof(mp3_data), player_config) != 0)
{
vTaskDelay(500/ portTICK_PERIOD_MS);
ESP_LOGI(TAG,"play_mp3_file vTaskDelay ing\r\n");
}
vTaskDelay(3000/ portTICK_PERIOD_MS);
}
fclose(f);
printf("delete play_mp3_file_task.\r\n");
vTaskDelete(NULL);
}

void web_radio_start(web_radio_t *config)
{
// start reader task
//xTaskCreatePinnedToCore(&http_get_task, "http_get_task", 2560, config, 20,
//NULL, 0);
ESP_LOGI(TAG,"web_radio_start\r\n");
xTaskCreate(&play_mp3_file, "play_mp3_file", 4096+4096, config, 5, NULL);

}

and the debug log is:

Is there any hint or solution for solving this problem?
thank you in advance.

Very cool project!

I was able to build the project and flash it onto the sparkfun esp32 thing board. I can play an MP3 stream with the built in DAC, but I can't enable the bluetooth in the menuconfig. Any idea why the bluetooth is not an option?

Bluetooth has been successfully connected, and the serial port has been read music information. Pin has also been confirmed, but not the slightest sound.

After getting it to work(note: cmd is not gnd...), I was playing around with it and I can't get it to play over bluetooth when the audio mode is set to pdm. It gives the error below:

and just sounds like it repeats the same sample over and over.
It doesn't have this issue when streaming over wifi.

Constantly getting buffer underflow.... Im using ESP Wroom 32 module. Do i need Wrover with PSram to run this app?

(164423) mad_decoder: Buffer underflow, need 2471 bytes

Hello,
Can you give any hints on what circuit I need to amplify the PDM output?
Thanks!

I have the code running on a ESP-WROOM-32 with a PCM5102A connected as follows:

ESP32        <------->    PCM5102A

GPIO 22                   DIN
GPIO 25                   LCK
GPIO 26                   BCK

FLT, DMP, SCL, FMT on the PCM5102A are on GND
XMT to VCC or other positive voltage, see below.

XMT hooked up to VCC as well I tried with a 4k/1k voltage divder to roughly 2.7V as I've seen in this schematic
Also tried powering the entire audio module with eighter 3.3V or 5V and adding a capacitor for voltage stabilisation, but with no effect in the errorneuos behavior.

Problem is, that after streaming via bluetooth fine for roughly 30s-2min, the ESP32 is crashing:

Tasks currently running:
CPU 0: BtcMediaT

CPU 1: IDLE
ASSERT_ERR((EM_BT_RXDESC_OFFSET + ld_env.curr_rxdesc_index * REG_EM_BT_RXDESC_SIZE) == bt_et_currentrxdescptr_currentrxdescptr_getf()), in ld_acl.c at line 1900ets Jun  8 2016 00:22:57

Steaming has done from an iphone as well as from a mac with showing the same behaviour.

ld_acl.c seems to be part of the espressif BT implementation, but I couldn't the code to get an idea whats going wrong. I am pretty clueless what might be the issue. Any suggestions?
I am aware, that this issue is obviously not in the ESP32_MP3_Decoder code but I hope that someone here has an idea in what direction to look.

Any help is much appreciated! :-D

not issue, nice project!

can be this code somehow "translated" to esp32?

I update the latest version and find that there is something wrong.It shows that image overflows.

It would be nice if it was possible to use ESP32 as bluetooth/wifi speaker. So i can stream audio to it not only using bt, but also over wifi. From my Linux box, using pulseaudio.

I use the I2S mode， but only left channel works， right channel outputs nothing.

My DAC is es9018K2M chip.

Hi Michael,

I reviewed the history, and think it should work for Built-In DAC case, but when I tried to run the latest code with latest ESP-IDF, I failed.

It seems that it's the version of ESP-IDF that does not match with this code. To be more specific, it's the version of I2S driver of ESP-IDF that does not match. In the latest I2S driver, it does not support the 8 bit width per sample.

I don't know why and how, could you tell me which version of ESP-IDF you are using? Or could you have a check at the latest ESP-IDF?

The version of ESP-IDF I'm using is 07b61d5 (2017-04-28)

Thanks & Best Regards,
Tidy Jiang.

Hello guys,
i just flashed my esp32 with this great Software, but I want to use it with Hifiberry Digi (WM 8804 SPDIF IC). The I2S transmission seems to work as far as I can See with my oscilloscope, but I don't get SPDIF Signals. The WM8804 board work quite good with my Raspberry Pi, but not with the ESP. Do you know if i need to configure something else? Please help me...

Maybe this is just me being stupid, but where does ini.h come from?
When I try to build I got this error:
ESP32_MP3_Decoder/components/playlist/./playlist.c:19:17: fatal error: ini.h: No such file or directory
And I have tried: "git submodule init && git submodule update", in the esp-idf directory
Any suggestion is much appreciated! Thanks in advance.

I've replicated this excellent project using an ESP32 Dev Board and Adafruit MAX98357A Breakout #3006 such that continuous music streamed from my Android phone to ESP_SPEAKER sounds fine.

My issue, however, is that short, intermittent sound clips from the phone are initially somewhat truncated e.g. "Welcome to Android" might be heard "come to Android." The same audio thru the phone's native speaker is not truncated.

So, judging wake up lag to be at fault, I might prime the Bluetooth audio path by sending brief silence before each sound clip. This seems kludgy though and I'm hoping for deeper understanding and perhaps a better solution. Any thoughts?

Thanks!

Note: not an actual issue.

It would be nice to have a wiki showing up various compatible hardwares and project derived from your code.

Right now I am building a breakout for the TAS5733L because the MAX chip is very limited. Will it work with this code? I have no idea. Theoretically it should, but having a clear wiki that says "YES" would be a great resource.

Cheers,
Tony

ESP32_MP3_Decoder can play mp3 and acc files on my ESP32.

I want to run ESP32_MP3_Decoder in mongoose-os for ESP32.

I do some code migration, Codes can be copmlied and linked with no errors.

Mp3/MAD part works well.

But AAC/fdk-aac part always reports E (5264) fdkaac_decoder: malloc failed 90 when running.

In the code

        /* create decoder instance */
        handle = aacDecoder_Open(TT_MP4_ADTS, /* num layers */1);
        if (handle == NULL) {
            ESP_LOGE(TAG, "malloc failed %d", __LINE__);
            goto cleanup;
        }

aacDecoder_Open always return NULL.

In file accdecoder.cpp

LINKSPEC_CPP HANDLE_AACDECODER CAacDecoder_Open(TRANSPORT_TYPE bsFormat)    /*!< bitstream format (adif,adts,loas,...). */
{
  HANDLE_AACDECODER self;

  self = GetAacDecoder();
  if (self == NULL) {
    ESP_LOGE(TAG, "GetAacDecoder failed");
    goto bail;
  }
.....
}

self = GetAacDecoder() is always NULL.

Can you give me some help?

I can connect but when I start streaming the speaker just makes white noise as if I'm just playing a blank audio file. Tried on both android and iphone with same result.

I am using WROOM32 with an I2S speaker. I've had it working before but I'm on a different computer and won't be back to that one for a couple days.

Any idea what is going on?

Hi BuddyCasino,
I was wondering you could point-out where would be the right place to start for displaying playing song when in Bluetooth Speaker mode.

Thank you

When pressing the IO0 in the mode of the web radio,the chip will reboot.

I am using this project as bluetooth speaker. After connect my phone to ESP32, when I am making a call, the player keep repeating same sound until I stop calling.

The solution is call renderer_stop on a2dp receiving status 0.

Right now there is another problem. When renderer_start called, there's some noise before playing the audio. I am looking for a way to deal with that.

Thanks for making this available!
When testing, I had to make the following changes:

• In playerconfig.h, each of the port numbers should be specified as strings (adding the double quotes before and after)
• Modify the pin numbers for the i2s module in app_main.c line 269~271, making sure you use an output pin for data out (gpio<33)

I don't know why the esp32 bluetooth speaker must be in crash when the module get audio data over 15500 .The ESP32 break down .Can you show me your menuconfig about ESP32-specific and Bluetooth ?

The setting options for bluetooth are missing.

minicom shows the audio data in transit, but there is no volume. My din gain pin is not connected, and my module is max98357A

In aacdecoder.cpp in fdk-aac lib,

CAacDecoder_Open() call GetAacDecoder() function.

GetAacDecoder() is not declared and defined, but can execute well.

Where is GetAacDecoder() declared and defined?

WebRadio doesn't play in DAC and PDM modes when apll_use=1 (in PDM mode it is very slow, in DAC mode - some cracks). When set apll_use=0 radio works. Nothing changed except apll_use.

Sir I can not run your demo
ERROR：/ESP32_MP3_Decoder/components/playlist/./playlist.c:19:17: fatal error: ini.h: No such file or directory
And I want decode MP3 file in SD card but the stack overflow ，I'd appreciate for your help
Here is part of my code ：
static enum mad_flow input(void *data, struct mad_stream *stream)
{
printf("input data \n");
mp3_file *mp3fp;
int ret_code;
int unproc_data_size; /the unprocessed data's size/
int copy_size;
mp3fp = (mp3_file *)data;
if(mp3fp->fpos < mp3fp->flen){
unproc_data_size = stream->bufend - stream->next_frame;
memcpy(mp3fp->fbuf, mp3fp->fbuf + mp3fp->fbsize - unproc_data_size, unproc_data_size);
copy_size = BUFSIZE - unproc_data_size;
if(mp3fp->fpos + copy_size > mp3fp->flen){
copy_size = mp3fp->flen - mp3fp->fpos;
}
printf("copy_size=%d \n",copy_size);
fread(mp3fp->fbuf+unproc_data_size, 1, copy_size, mp3fp->fp);
mp3fp->fbsize = unproc_data_size + copy_size;
mp3fp->fpos += copy_size;
mad_stream_buffer(stream, mp3fp->fbuf, mp3fp->fbsize);
ret_code = MAD_FLOW_CONTINUE;
}else{
ret_code = MAD_FLOW_STOP;
}
return (mad_flow)ret_code;
}

static int decode(mp3_file mp3fp)
{
struct mad_decoder decoder;
int result;
/ configure input, output, and error functions /
mad_decoder_init(&decoder, mp3fp,
input, 0 / header /, 0 / filter /, output,
error, 0 / message */);

/* start decoding */
result = mad_decoder_run(&decoder, MAD_DECODER_MODE_SYNC);

/* release the decoder */
mad_decoder_finish(&decoder);

return result;

}

Everything works as expected in master mode,
but if I try to set up Slave mode, in audio_render.c:
i2s_mode_t mode = I2S_MODE_SLAVE | I2S_MODE_TX;

Esp32 is correctly not generating clock but waiting for it and replying with data,
hovewer the generated data is full of noise even if it's correctly synchronized.

Some mp3 file will make the decoder crash.

I have an error like below when I start aac decoder.

I (47596) audio_player: created decoder task: fdkaac_decoder_task
E (47596) fdkaac_decoder: malloc failed 88
I (47606) fdkaac_decoder: aac decoder finished

I think it is better to add some lines like these:
void audio_player_start()
{
renderer_start();
//added--------------
player_instance->media_stream->eof = false;
//----------------------
player_instance->command = CMD_START;
player_status = RUNNING;
}

void audio_player_stop()
{
renderer_stop();
player_instance->command = CMD_STOP;
//added---------------
player_instance->media_stream->eof = true;
//------------------------------------
player_status = STOPPED;
}

Otherwise the decoder is not halted if media_stream->eof is not set .
I don't use web_radio.c. (that's why;-)

I want to use this with my esp8266. It has onboard wifi, but no bluetooth. I just want to stream music to a wired speaker. Is that possible?

Hi there,
Would very appreciate if you could render some help there. I compiled the code successfully, however, when I tried to connect/pair it. It failed. Any idea why? Here are the message.

i was trying to play http://lr1mp1.latvijasradio.lv:8012 but it seems it requires "Icy-MetaData:1" header in GET. Stream plays ok in vlc and another players.
Codec: MPEG Audio layer 1/2 (mpga)
Sample rate: 44100 Hz

content type is not returned as audio/mpeg type so there must be another way to catch stream

Most notably deprecated functions:

But also a tons of other things: https://pastebin.com/HJuW5efB

Maybe this is just me being stupid, but where does ini.h come from?

Compiling the latest checkout in master gives me:
ESP32_MP3_Decoder/components/playlist/./playlist.c:19:17: fatal error: ini.h: No such file or directory

Any suggestion is much appreciated!

hi
Can i use this library to play MP3 file from SD card?
is possible ?
my sdcard already connected to ESP32.

So I've been playing with the code mostly using web radio. Today I wanted to try the bluetooth speaker. I downloaded a fresh copy of the code and got this message:

ESP32_MP3_Decoder_clean/components/bt_speaker/bt_speaker.c:93:9: error: implicit declaration of function 'esp_a2d_sink_register_data_callback' [-Werror=implicit-function-declaration]
         esp_a2d_sink_register_data_callback(bt_app_a2d_data_cb);
         ^
cc1.exe: some warnings being treated as errors

make: *** [C:/msys32/home/tony/esp/esp-idf-v3.0/make/project.mk:450: component-bt_speaker-build] Error 2

Seems like you can't compile the code anymore with just "make" you have to change the default esp-idf config (under make/project.mk) and set the following gcc flag:

-Wno-error=implicit-function-declaration

And this is a pretty scary flag to include!

Experiencing the error and used the command grep -rnw '.' -e 'mdns_server_t' to find the definition but not found. Very strange! Any advice? please

Per https://cast.readme.io/v1.0/docs/icy if header contains Icy-MetaData: 1 server can send back some metadata which typically includes song title.
After adding Icy-MetaData: 1 to headers ESP32 player plays ok and then goes mad and starts to blame with decoder errors:
Buffer underflow
lost synchronization

Metadata feature could be great to show played track title on oled display.
Stream with metadata: http://live.pieci.lv/live19-hq.mp3

Running without the I2S codec can be activated by uncommenting "#define USE_DAC", but this does not currently work.

If anyone has experience using I2S_MODE_DAC_BUILT_IN, please have a look!

Sir, hello. Because my pin is not a lot, my GPIO 22 used other functions, so DATA can not be connected. I really wanted to implement Bluetooth music, but I did not find a way to change the pin's code. I hope to get your help, thank you very much. Wish you a Happy New Year!

in main/wifi.c on line 34, 38, 42, 46, 50 and 54 there seems to be missing the trailing ;
when I added them, the compile ran successful.

Hi Michael,

I am in the translation of the following error.
D:/path/to/ESP32_MP3/esp-idf-template/components/playlist/playlist.c: In function 'playlist_load_pls':
D:/path/to/ESP32_MP3/esp-idf-template/components/playlist/playlist.c:146:15: error: implicit declaration of function 'ini_parse_stream' [-Werror=implicit-function-declaration]
int res = ini_parse_stream(pls_ini_reader, &file_start_ptr, pls_ini_handler, playlist->entries_vec);

Is it because I am missing a library?

Thank you！
