I want to stream multiple audio tracks to Icecast. Input is FLAC stream from the same server and outputs have different bitrates. The problem is that the first streams work if I remove 3 last streams. If not, I get error 403 for the second and probably for next streams.

ffmpeg -i http://localhost:8000/stream

-c:a libopus -b:a 128k -f ogg  -content_type application/ogg icecast://source:test@localhost:8000/opus

-c:a libopus -b:a 96k -f ogg  -content_type application/ogg icecast://source:test@localhost:8000/opus96

-c:a libopus -b:a 48k -f ogg  -content_type application/ogg icecast://source:test@localhost:8000/opus48

Is Icecast in its default configuration?

By default Icecast is set up to allow 2 source connections concurrently.
https://icecast.org/docs/icecast-2.4.1/config-file.html#limits

<limits>

    …

    <sources>2</sources>

    …

</limits>

After editing the Icecast configuration you must either restart it or send a SIGHUP to it.

You can also see details in the error.log for Icecast.
