Some Shoutcast MP3 radio streams fail to play (Radio eM Katowice and Kielce)

[michalkasperczak]

Summary

FastPlay 0.6.6 fails to play two working Polish Radio Browser entries:

• Radio eM (Katowice): http://194.181.177.253:8000/
• Radio eM Kielce: http://emkielce.pl:8000/;

Both endpoints are currently reachable and advertise a 128 kbps audio/mpeg stream, but playback does not start in FastPlay.

Steps to reproduce

1. Open Internet Radio.
2. Choose the Radio Browser search.
3. Search for Radio eM.
4. Try to play either Radio eM (homepage: radioem.pl; Katowice) or Radio eM Kielce.

Expected result

The selected station starts playing, like other MP3 radio streams.

Actual result

Playback fails for both stations.

Protocol details

The two streams expose useful edge cases:

Radio eM Katowice

The server returns the legacy Shoutcast status line:

ICY 200 OK
content-type: audio/mpeg
icy-br: 128
icy-metaint: 4096

It identifies itself as Shoutcast DNAS 1.9.4.

Radio eM Kielce

The direct URL intentionally ends in a semicolon. The server returns:

HTTP/1.0 200 OK
content-type: audio/mpeg
icy-br: 128
icy-sr: 44100
icy-metaint: 16384

It identifies itself as Shoutcast DNAS 2.6.1. The trailing ; should be preserved when resolving or normalizing the URL.

Suggested direction

Could FastPlay preserve unusual but valid Radio Browser stream URLs and add a tolerant fallback for legacy ICY/Shoutcast responses when the normal BASS URL open fails? It may also help to expose/log the exact BASS_ErrorGetCode() value after each failed attempt, so it is clear whether the failure happens during URL resolution or stream creation.

This should preferably be a general compatibility fix rather than a station-specific exception.

Additional compatibility/regression candidates

These have also caused intermittent compatibility problems in other players. They are not yet confirmed as the same FastPlay failure, but would be useful regression cases for the general radio-stream handling:

• Radio Emaus (OGG): http://stream.radioemaus.pl:8000/oggstream — Icecast 2.4.4, audio/ogg, 128 kbps, 48 kHz stereo.
• Radio Emaus (MP3): http://stream.radioemaus.pl:8000/mp3stream — Icecast 2.4.4, audio/mpeg, 128 kbps, ICY metadata.
• TyfloRadio playlist: http://radio.tyflopodcast.net:8000/listen.pls — PLS containing http://radio.tyflopodcast.net/.
• TyfloRadio direct stream: https://radio.tyflopodcast.net/ — audio/mpeg, 192 kbps. The HTTP address redirects to HTTPS.

Together these cover legacy ICY status lines, HTTP/1.0 Icecast responses, OGG and MP3 streams, PLS resolution, redirects, unusual URL endings, and ICY metadata.
