ENCODER sbc ERROR

[aqildad-create]

After some diagnose and trouble shooing i observe below line through exception ,
AudioInfo to(44100, 2, 16);
SBCEncoder encoder;
.
encoder.begin(to);
.
.
.
static uint8_t buffer[512];
encoder.write(buffer, 512); //.>>>>>>>>>>>>>>> THIS LINE GIVE EXCEPTION ERROR

BELOW IS COMPLETE CODE ,

#738

You should probably only use Encoders directly if you know what you are doing and if you are able to analyse errors in order to figure out what you are doing wrong. My first rough guess is that you just forgot to indicate the output.
So please stick with the examples using the EncodedAudioStream...

If you find any errors, please feel free to correct them and share the correction with a pull request.

File EncodedDataFile; SBCEncoder encoder(EncodedDataFile); In complete code I write encoded data to file , I think this is encoder out put .it also through same exemption which image I have uploaded . Further for this test I follow your other example which is without encoded stream .. I think this should also work ..

What are you talking about ? Look at the class documentation of the SBCEncoder!
The constructor is asking for SBC parameters!

[aqildad-create]

this is the minimal code which reproduce this issue
is any parameter still missing ?

#include "AudioTools.h"
#include "AudioCodecs/CodecSBC.h"
AudioInfo to(44100, 2, 16);
SBCEncoder encoder;
void setup(void) {
Serial.begin(115200);
AudioLogger::instance().begin(Serial, AudioLogger::Info);
encoder.begin(to);
static uint8_t buffer[512];
encoder.write(buffer, 512);
}
void loop() {

}

[pschatzmann]

You did not specify the output: Look at the class documentation how to do this!

[aqildad-create]

I am extremely apology for annoying question.

I am in class documentation but i cant figure out how to specify the out put in above minimal code please .

[pschatzmann]

Use the setOutputStream() method!

[aqildad-create]

ok some thing like this ? and see the out put 75 bytes have data its means 512 bytes of uncompressed data compressed to 75 bytes ?

#include "AudioTools.h"
#include "AudioCodecs/CodecSBC.h"
AudioInfo to(44100, 2, 16);
SBCEncoder encoder;
RingBufferStream outdata;
void setup(void) {
Serial.begin(115200);
AudioLogger::instance().begin(Serial, AudioLogger::Info);
encoder.begin(to);
encoder.setOutputStream(outdata);
static uint8_t buffer[512];
encoder.write(buffer, 512);
outdata.readBytes(buffer, 512);
for(int aa=0;aa<512;aa++) // view compressed data
Serial.println(String(aa)+":"+buffer[aa]);

}

void loop() {

}

It depends on the parameters. You can query the API for the input and output record size
