How to read a Mp3 file form URL and plays on I2S (streams-url_mp3_mad-i2s)

GoFuuu commented 8 months ago

Problem Description

Thank you for the wonderful library! I am currently trying out one of the example project: "streams-url_mp3_mad-i2s“.And I'm going to use the ESP32 to play the static mp3 on my server

The only changes done to the sketch are:

Pin-out for the i2S WIFI credentials URL which points to a static mp3 file on my web server.

I've already tested the url from the example("http://stream.srg-ssr.ch/m/rsj/mp3_128") .It works ,but when try to ues my own URL which points to a static mp3 file on my web server. It can't work and reboot again and again.

I guess it because run out of memory because the output of the serial monitor :

"Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled."

I'm wondering if it might be because I need streaming URL rather than URL that point to fixed mp3 files.

How can I play the static mp3 file on ESP32 successfully?

here is the full serial output info:

You should try to analyse where the issue is!

Decode the stack-trace: that will lead you to the line of code that is failing.
Set the log level to debug: that will also give you a hint how far the processing goes successfully

I am never using MAD myself and prefer LibHelix. You might also try that... Since you confirm that my sketch is working, the issue must be with your server or your mp3 file!

I found that it was my network error
