Icecast - Jul 2021 - Streaming OGG/Vorbis files dies on track change

Hi.

I'm having issues with streaming OGG/Vorbis files to Icecast. I am using 
Ezsteam to stream a playlist of Ogg files from the command line, but 
when there is a track change the stream stops in clients like Clementine 
and Windows Media Player. MPV client reports a discontinuity but carries 
on playing.

I have also test using Mixxx to stream as Ogg to the same icecast server 
but it has the same issue. Only B.U.T.T. seems to handle track changes well.

This is my mount details from the icecast XML file.

 ??? <mount type="normal">
 ??????? <mount-name>/stream8001</mount-name>
 ??????? <username>s8001</username>
 ??????? <password>redacted</password>
 ???? </mount>

There are no issues with streaming MP3 at all as far as I can see. But 
since I need to use EZstream OGG format is my only option.

I'm looking at MPD+ncmpcpp as an alternative (more reading) but I would 
like to stick with Ezstream at this point since I have it running.

This track change issue with ogg files seems to be a known issue. But 
reading the docs a bit more I wonder if the use of a fallback-mount 
setting using an ogg file of 5 secs of silence would fix things?

Help,

Chris.

Good afternoon,

That is a strange name for a mount.
Please also keep in mind that some broken players expect Ogg/Vorbis
streams to have an URI ending with ".ogg". This is NOT a problem of
Icecast, but of some players. So consider to change this.

It depends on what the actual problem is. But I suspect it is not that
the source client drops the connection. A fallback would only help in
that case.

You can check this by having a look at your access.log. If it lists one
SOURCE, or PUT request per track, than this is the problem (and the
source client is having some issue). If you see only one SOURCE, or PUT
request for each runtime of the source client, then it does at least
this correctly.


Is there a public URI to your stream so we can have a look?


With best regards,
