Play specific file with setPath

[luke2023]

Hello,I tested the player-sd-a2dp example with files: /baby.mp3 /rickroll.mp3 /sun.mp3 But no mater I use source.setPath(“/rickroll.mp3”);or player.setPath (“/rickroll.mp3”); it plays baby first and than rickroll And neither I use source.nextStream(); source.selectSream(): It shows error What commend should I use for playing rickroll? Thank you very much Lin Che

What is the error message ? Probably you see better what the player is doing if you set the log level to Debug

Maybe just calling player.setIndex(1) instead is doing what you need.

@pschatzmann Thank you!But after I read the description ,"setIndex"is "moves to selected file " Seems it's what I want ,but how do I select what filename or file path I want to play,thanks LinChe

[pschatzmann]

You were writing it plays baby first and than rickroll So baby is 0 and rickroll is 1

@pschatzmann Thank you very much! It does play what I want ! But is it possible to play mp3 by path?or I can only order all of them in alphabet order and give them 0,1,2？Thank you

[pschatzmann]

You did not provide me the error messages yet...

@pschatzmann Oh,here it is: Code ` #define USE_SDFAT #include "AudioTools.h" #include "AudioLibs/AudioA2DP.h" #include "AudioCodecs/CodecMP3Helix.h"

const char startFilePath="/"; const char ext="mp3"; const char* na="m"; AudioSourceSdFat source(startFilePath, ext); A2DPStream out = A2DPStream::instance(); // A2DP input - A2DPStream is a singleton! MP3DecoderHelix decoder; AudioPlayer player(source, out, decoder);

void setup() { Serial.begin(115200); //source.setPath("/mu"); // player.setPath("/mu.mp3"); AudioLogger::instance().begin(Serial, AudioLogger::Warning);

// setup output - We send the test signal via A2DP - so we conect to the "LEXON MINO L" Bluetooth Speaker auto cfg = out.defaultConfig(TX_MODE); cfg.name = "BT-SPEAKER"; //cfg.auto_reconnect = true; // if this is use we just quickly connect to the last device ignoring cfg.name out.begin(cfg);

// setup player

player.setVolume(0.05); player.begin(); player.setIndex(1);

}

void loop() { player.copy(); Serial.print(player.toStr()); Serial.print(player.nextStream()); Serial.println(player.selectStream()); } ` Error(can't find any of Serial.print....):

Just made a test and for me both setPath() and setIndex() are working as expected.

Are you sure that you used the correct path ? Maybe it makes a difference if you move the files into a subdirectory ?

[luke2023]

@pschatzmann Well I don't know why if I use setIndex,it does work,but setpath doesn't ,and it output very little noise (Player-sd-a2dp)esp32s Thank you (By the way ,audiokid can't work on esp32)

[pschatzmann]

The AudioKit is a audio board with an ESP32 and an ES8388 audio chip. You can use all the examples: just replace the AudioKitStream with e.g. an I2SStream

Did you try to move the audio files into a subdirectory ?

[luke2023]

@pschatzmann Bingo! It works!Thank you for helping,after set it to /ex/rickroll.mp3,it did it's job! LinChe

[pschatzmann]

Cool, I will double check why it's not working for files in the root...

[luke2023]

@pschatzmann Thank you for helping!Good luck!

[pschatzmann]

I just did some tests with some files in the root and for me this is working as well: In the setup I used

  // setup player
  player.setVolume(0.7);
  player.begin();

  // select file with setPath() or setIndex()
  player.setPath("/002.mp3");

[luke2023]

@pschatzmann Thank you!But I can only use sub file

[pschatzmann]

In the meantime I have added the support for other SD implementations. In all my tests the following was working:

 player.setPath("/ZZ Top/Unknown Album/Lowrider.mp3");

I am therefore closing this issue.
