BUG? Issues with HTTPS Radio Streams on ESP32 (v1.1.3) - Not all work.

[phploader]

I'm currently using the latest version of the library: v1.1.3
https://github.com/pschatzmann/arduino-audio-tools#v1.1.3

While testing online radio stations via HTTPS, I encountered some issues.

I’m aware that v1.1.3 introduced improvements regarding HTTPS and port handling. However, I’m still experiencing problems with certain streams that play fine in a web browser but fail to work on the ESP32.

Important: The issue does not occur with all stations I’ve tested, which suggests that my code is generally working as expected.

Code snippet:

source = "https://radio-url";
url.begin(source);
Decoder.setOutput(*kit);
Decoder.setInput(url);
Decoder.setMimeSource(url);
Decoder.begin();

Example streams that fail to play:
https://superrtl.streamabc.net/srtl-sporthits-mp3-128-9063651
https://radio.toggo.de/sporthits/mp3-128
https://superrtl.streamabc.net/srtl-kinderzimmer-mp3-128-7566112

I’d appreciate any insights on whether additional configuration is needed or if this might be a bug.

I can't reproduce your issues. Here is the log for the first of your mentioned url:

So,

• make sure that you use an actual ESP32 core version: the current version is 3.3.0!
• to rule out that it is failing due to missing RAM: use a version with PSRAM and activate PSRAM or use a test sketch w/o mp3 decoder.
• make sure that you have good connection to your router: client can get stuck (hang) when the Wi-Fi connection is weak or unreliable
• set the core debug level to verbose to get detailed output from the underlying libraries
