Buffer underflow with Icy-MetaData: 1 with Dac-Audio

[unkown12345]

Hi, Icy-MetaData works: http.c
if(asprintf(&request, "%s%s%s%s%s%s", "GET ", url->path, " HTTP/1.0\r\nHost: ", url->host, "\r\n","Icy-MetaData: 1\r\n\r\n") < 0)

but http://st01.dlf.de/dlf/01/128/mp3/stream.mp3 works only in Audio Output Mode -PDM . Other Audio Output Modes (no PDM ) gets error after 1 Minute "audio_player: Buffer fill " goes down from 98% and after 2 Minutes to 1-5% stable .....mad_decoder: Buffer underflow, need ...

The same with MrBuddyCasino/ESP32_MP3_Decoder. You dont need connect oled or Dac-Device to test it.

I hope other Users can reproduce it and give solutions.

I have tried a lot, example When I stop the decoder-Output for 100millisecondes the audio_player: Buffer fill 98% and goes down after 1 Minutes .....

I have understand Input-Raw-Data-http-frames are visible in parser , frame.c find mp3-Data stream.c sream out Data to i2s

but I dont understand where I have to search.

The Input-Data makes trouble only when Audio Output Modes is no PDM , lookes like i2s problem ? Input-Raw-Data needs more time fill fifo, is this right ? But why Problems after exactly 1 Minute sudently , looks like overrun error ?

I hope some body have time are interestet or have a link how it works the decoding process from Raw-Data-http-frames to i2s and which files in mad serve it .

I have tested with http://st01.dlf.de/dlf/01/128/mp3/stream.mp3 buffer goes down after 1 Minute with http://st01.dlf.de/dlf/01/64/mp3/stream.mp3 buffer goes down after 2 Minute

Thx Reini

Hi again, I solved problems with Icy-MetaData. I write a http-Icy-MetaData-Parser to show StreamTitle in Oled-SSD1306_6432.

I will share it with kodera2t for next update. Please contact me to send files: ritaripp@gmx.de Thx Reini
