Hi, I try to find out how to update the meta data on a flac or opus stream. Look like its not support this formats. And update interface do not work. Is there a solution to make this work?

However for every non-legacy formats such as all Ogg-based, all Matroska-based, and FLAC metadata is supported by the format itself. Icecast will happily relay any metadata updates send by the encoder.> Is there a solution to make this work?Yes. Set the metadata in your encoder. See it's documentation on how to do that.

(Yes, it's annoying that there is this inconsistency.) In addition, many clients are not able to accept metadata updates as part of the Ogg (FLAC, Vorbis, Opus) stream, expecting ICY metadata only. Also, some buggy clients consider a change of metadata in an Ogg stream (which is usually accompanied by a change in stream serial number) as being the end of streaming, and will stop playback on a metadata change. -- Paul Martin <pm at nowster.me.uk>
Hi Paul Martin, Thank you for the information. I send it to the developer of Playout software of ProppFrexx on air.
