codec: UNKNOWN library not start any stream since esp32 core 2.0.3

[Sentinel8000]

I got this messages from serial monitor:

0:18:00.977 -> Simple vs1053 Streaming example.
20:18:03.259 -> wifi connected - starting decoder
20:18:06.519 -> decoder running - starting stream
20:18:06.566 -> codec: UNKNOWN

I tryed several url:

http://mp3.hitradiort1.c.nmdn.net/rt1eurodancewl/livestream.mp3

http://89.39.189.52:8000/stream/1/

I have used expressif esp32 board with vs1053, set these pins:

#define VS1053_CS 5
#define VS1053_DCS 16
#define VS1053_DREQ 4

[CelliesProjects]

Hmm not really sure. All the stream urls above work ok for me.
I think you are trying the example with only changed pins?

[Sentinel8000]

I try my best give more detailed feedback. Here is the actual code, maybe something missing.

I have the newest esp32 firmware in arduino ide and this is the actual code what still giving this in serial monitor:

#define VS1053_CS     5
#define VS1053_DCS    16
#define VS1053_DREQ   4

ESP32_VS1053_Stream stream;

const char* SSID = "xxxx";
const char* PSK = "xxxx";

void setup() {
    Serial.begin(115200);

    WiFi.begin(SSID, PSK);

    Serial.println("\n\nSimple vs1053 Streaming example.");

    while (!WiFi.isConnected())
        delay(10);
    Serial.println("wifi connected - starting decoder");

    SPI.begin();  /* start SPI before starting decoder */

    stream.startDecoder(VS1053_CS, VS1053_DCS, VS1053_DREQ);

    Serial.println("decoder running - starting stream");

    stream.connecttohost("http://mp3.ffh.de/ffhchannels/hqeurodance.mp3");

    Serial.print("codec: ");
    Serial.println(stream.currentCodec());
}

void loop() {
    stream.loop();
}

void audio_showstation(const char* info) {
    Serial.printf("showstation: %s\n", info);
}

void audio_showstreamtitle(const char* info) {
    Serial.printf("streamtitle: %s\n", info);
}

void audio_eof_stream(const char* info) {
    Serial.printf("eof: %s\n", info);
}

And here is the original example, whats currently working well by me, i have used this example pins:

I just compiled with esp32 core version 2.0.3 and then I can reproduce your problem.

With 2.0.2 it works for me. Could you please try to compile and flash with 2.0.2?

[Sentinel8000]

You have right, thats was the problem, now working well:) You need notice this in description to prevent this issue or check what is the problem with the new core.

Thank you for investigation, have a nice day.

[Sentinel8000]

Just a question - this is not issue, because im not pro developer, how can i display on serial monitor just one function, not the full function loop? example if i want see just the audio_showstreamtitle?

[CelliesProjects]

Thanks for checking out the problem. Something has changed between 2.0.2 and 2.0.3 that does not agree with this lib.

For now just use 2.0.2, until I debug this issue.

About audio_showstreamtitle, audio_showstation and audio_eof_stream:

You can use these routines, but you don't have to, as they are weakly linked so optional.

[Sentinel8000]

I try simple make this, using your included example, but im unable to compile.

I dont know what a parameter i need give for audioshowstreamtitle:

#include <VS1053.h>            
#include <ESP32_VS1053_Stream.h>

#define VS1053_CS     5
#define VS1053_DCS    16
#define VS1053_DREQ   4

ESP32_VS1053_Stream stream;

const char* SSID = "xxxx";
const char* PSK = "xxxx";

void setup() {
    Serial.begin(115200);
    WiFi.begin(SSID, PSK);

    while (!WiFi.isConnected())
        delay(10);

    SPI.begin();  
    stream.startDecoder(VS1053_CS, VS1053_DCS, VS1053_DREQ);
    stream.connecttohost("http://mp3.ffh.de/ffhchannels/hqeurodance.mp3");

}

void loop() {

   audio_showstreamtitle();   //?

}

Possible to run in this form and/or impossible or i have forget something?

[CelliesProjects]

The three audio_xxx functions are called automatically when stream data becomes available. (And you have an instance of that particular function)

The data becomes available through const char* info.
If you want to use that data later on in your program you will have to save it.
In the example below the station name is saved as String currentStation and can be used throughout the rest of the code.

And to proccess the stream stream.loop() has to be called every couple of milliseconds.

#include <VS1053.h>            
#include <ESP32_VS1053_Stream.h>

#define VS1053_CS     5
#define VS1053_DCS    16
#define VS1053_DREQ   4

ESP32_VS1053_Stream stream;

const char* SSID = "xxxx";
const char* PSK = "xxxx";

String currentSong = "";

void setup() {
    Serial.begin(115200);
    WiFi.begin(SSID, PSK);

    while (!WiFi.isConnected())
        delay(10);

    SPI.begin();  
    stream.startDecoder(VS1053_CS, VS1053_DCS, VS1053_DREQ);
    stream.connecttohost("http://mp3.ffh.de/ffhchannels/hqeurodance.mp3");

}

void loop() {
    stream.loop();
}

void audio_showstreamtitle(const char* info) {
    currentSong = info;
    Serial.printf("currently playing: %s\n", currentSong.c_str());
}

[Sentinel8000]

This loop call method was for me new, never seen before.

Translate to my basic language this stream.loop(); call a collection of functions:

audio_showstation(const char* info)
audio_showstreamtitle(const char* info)
audio_eof_stream(const char* info)

and i can remove what i dont need.

Also this sream.loop() dont call any other functions what is not part of this library.

I have checked also the sound (ealier i have just want see the decoded url) and i need report, i dont have sound from the vs1053 jack decoder. Please check this too if you have time.

[CelliesProjects]

It looks like a bug in HTTPClient -or some underlying code- causes this issue.
The http.begin() call has some weird behaviour after setting http.setConnectTimeout() as in timing out before the set time has elapsed.
See https://gitter.im/espressif/arduino-esp32?at=6288f01367db9a59dbdde996

[CelliesProjects]

And should be fixed 26 days ago in master with espressif/arduino-esp32#6633

[Sentinel8000]

Ok thanks for the information, i will re check later.

[Sentinel8000]

If im good understand, after the fix, we can use your library with the new esp32 core too, but we still need wait for the fix.

Currently i have tested your library working well with esp32 core 2.0.2, i have just a question, and one notice/small issue

What if somebody try play a bad url? There is any error handling? Or normaly simple will not start the stream and i can catch this issue with stream.isRunning() and if i dont receive station name?

And i have noticed durint testing trouble with handling special characters - not typical use case, but can generate weird result if somebody try play not only english streams, example in my case hungarian. I dont know library can handle UTF8 characters, but currently if showstation or streamtitle have spacial characters like áéűúőöüóí and/or uppercase variants user will receive like this:

TOP FM r⸮di⸮ >> 90s, 00s what looks originaly TOP FM rádió >> 90s, 00s.

I dont know this need hard work to handle or do you want handle this, but i dont opened currenly new issue.

And realy just a update request, not issue, can we get the actual bitrate of the stream? or this can generate more touble example if have the stream variable bitrate?
