After few tracks, browser says "media could not be decoded" (streaming mp3's with ezstream and icecast2)

[vicmortelmans]

Hi,

I have a very basic setup with icecast2 and ezstream to stream a set of mp3 files (24/7 in random order).

When playing the stream in a browser, it will play a few tracks and then, appearantly random, stop on this error.

Media resource http://radio.jezus-hart.be/play could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_DECODE_ERR (0x806e0004)
Details: virtual MediaResult __thiscall mozilla::FFmpegAudioDecoder<46465650>::DoDecode(MediaRawData *, uint8_t *, int, bool *, DecodedData &): FFmpeg audio error

It plays a few tracks and then stops when starting a new track.

I've tested opening the stream in multiple browsers and VLC and they stop at the same time.

The streaming server keeps running, so refreshing the page continues playback.

I thought perhaps some of the mp3's were faulty, but I've re-encoded all of them with constant bitrate, and that didn't change the problem.

re-encoding didn't work:
ffmpeg -i xxxx.mp3 -codec:a libmp3lame -b:a 128k xxxx.cbr.mp3

So I suspect the problem is with ezstream or with icecast2?

This is from the icecast2 error.log at the point where the playback stops in the browser, but these messages appear each time a new track is strated, also when playback continues correctly:

The output of ezstream just says Streaming ... with the name of the file.
