Hi Philipp, I was concerned about the mountpoint name as well afterwards so now in my tests I used stream8001.ogg. But this did not change anything in the behaviour as I still had the same issues. Testing was re-done in a virtual machine and examined the access.log as suggested. I can confirm that there is only 1 SOURCE entry for the source client at runtime. EZSTREAM with ogg metadata sent 1/27.0.0.1 - - [06/Jul/2021:12:05:41 +0800] "SOURCE /stream8001.ogg HTTP/1.0" 401 331 "-" "libshout/2.4.5" 0// //10.1.1.20 - - [06/Jul/2021:12:12:34 +0800] "GET /stream8001.ogg HTTP/1.1" 200 5648489 "-" "Clementine 1.3.1" 405 <--------Clementine dies about 3 minutes after track change.

MPD+ncmpcpp work nicely last night on a test rig streaming MP3 so I am rebuilding my server with those. But I would still be curious about this issue as to what happened. Thanks, Chris.

[Icecast] Streaming OGG/Vorbis files dies on track change
Hi Kit,
My guess is that it's 1 of 2 things:
1) Your Ogg/Vorbis files are not encoded uniformly (i.e. differing
smaplerates/quality/num. of channels/etc.)
2) Your files need a trim :) Try this bash script on a sample of problem
files and see if it helps:
---
#!/bin/bash
#
# Fixes end-of-stream bug with ogg vorbis files so they don't
# cause some players to crash when moving to a new song in the
# stream.
#
for FILE in $(find /path/to/oggfiles -name '*.ogg'); do
cat /dev/null | vorbiscomment -a $FILE;
done
---
Cheers,
