Hi, Microntroller.

OK, that is a good explanation.
Thank you!

Nevertheless, we saw the number decrease -> increase > decrease. So probably is not that simple as a High Watermark.

Hi "Microcontroller".

The free number of bytes it what the function vTaskList() return in string relating to all tasks.
So task main() passes from 5248 free bytes to 4912 free bytes, loosing 336 bytes.
This is ONLY an example of much larger problem that we detected.

It is normal that the ...

We detected a stack leak in something that was not supposed.

It only occurs in the first call to a function, not in the following calls.

We reduced the problem to a simpler example that everyone can test:

Example 1:
Calling this function in task in task main

void test_main() {
char test ...

My code has several differences from the example "pipeline_sdcard_mp3_control":
- It reads USB pens instead of SD cards
- It reads mp3, aac and wav files, instead of only mp3 files
- It used a I2S DAC instead of a codec IC

The behavior is similar if I apply a mp3 decoder in a wav file. Error is ...

I am using a code altered by me from example pipeline_sdcard_mp3_control (https://github.com/espressif/esp-adf/tree/master/examples/player/pipeline_sdcard_mp3_control) and from example cli (https://github.com/espressif/esp-adf/tree/master/examples/cli) with changes to work with USB (form example msc ...

While playing music using pipeline of audio decoding of ESP-ADF I need to get information about the mp3 music that is paying.

Example of code: https://github.com/espressif/esp-adf/tree/master/examples/player/pipeline_http_select_decoder

It is not clear for me that ESP-ADP libraries can easily read ...

I invested my time with ADF examples I needed to try.
I retried to compile msc example from the master branch ESP-IDF v4.4.
Now the example compiles and runs correctly.

I have no explanation. Problem aparently solved.

I redeleted the git folder and copied the original v4.4 that I made a backup "just in case". My salvation!!!!

My ESP32 code now compiles again.
"msc" example became more condemned because now has new errors. Miss of files in v4.4 ... what an example.

I'll return to this problem again in a few ...

Hi ESP_Dazz.

I've had a lot of problems installing the IDE.
I started with VSCode + ESP-IDF for ESP32 (suggested on internet). The first uses were ok and I could develop for sometime, waiting the ESP-PROG arrival (12 days later).
I had difficulty putting ESP-PROG to debug and I went to the net and ...

Thank you again @ESP_Dazz

I've followed your suggestion. ESP-IDF now seems updated. I do not have yet experience with git, only svn.

Unfortunately, the msc example still does not compile because of a Python error:
