Stream error: unknown error - for remote audio stream (azuracast, aac)

[shtefane]

Hi, thank you for your work. I have tried to play some remote radio urls (Azuracast, icecast v2.4, aac - format) and getting this error:

"Audio file stream error'd: An unknown error occurred"

I reproduced the issue on your demo app AudioPlayer, added new URL (https://stream-eurodance90.fr:8000/64.aac) and have got the error on play.

The error is coming from assignMagicCookieToConverterIfNeeded(). First time the audioConverter is nil, after pressing stop and again play it works with no issues, but sometimes it returns error from the second breakpoint.

Can you try removing the fileStreanCallback?.raiseError.audioSystenError(.fileStreanError(.unknownError)))) and let me know if the audio plays?

We might have to treat this failure as non fatal.

[shtefane]

Yes, the audio plays if I comment error line, however the metadata is not processed. The problem is audioConverter is not yet created when the assignMagicCookieToConverterIfNeeded() is called. The order functions are called is: assignMagicCookieToConverterIfNeeded() processFormatList(entry: entry, fileStream: fileStream) processDataFormat(entry: entry, fileStream: fileStream) calls -> createAudioConverter() but audioConverter is still nil.

What do you mean by "the metadata is not processed."

I'm on holidays so I'll take a look at this next week.

[shtefane]

Metadata(now playing) text is not coming, the delegate method is not called. If I stop and play again or switch to a different stream, somehow videoConverter is created and the stream plays with nowPlaying text.

Can you give a try on the latest release 1.2.5 and let me know if it fixes this issue? thanks

[shtefane]

The playback works without any error from the first time, but the Now Playing appears only when I stop the stream and start it again. The same behaviour is with Enlefko station from demo (you can try it).

[dimitris-c]

So That's a different issue - not related with the fatal error you reported

[shtefane]

Yes it's different. Thanks for fixing playbacks

[dimitris-c]

btw the metadata issue is a bug on the example project, the library parse the metadata correctly

[shtefane]

Yes, the bug is in demo example. Metadata is processed well but it comes before the stream start playing and in AudioPlayerControls the isLiveAudioStreaming var is false and Text is just not displayed.

 if let audioMetadata = model.liveAudioMetadata, model.isLiveAudioStreaming {
                Text("Now Playing: \(audioMetadata)")
