Invalid FLAC bitstream and invalid image errors

[baasheep]

Hi, I am getting invalid FLAC bitstream and invalid image format errors in the system log when updating moode library from files on my NAS. The files play and images display fine, so this is not a significant problem. However, it does make it difficult to spot real file errors from studying the log. These errors appear with files tagged by different applications including xld, eac, kid3 and mp3tag. Can anyone explain why the errors display for files that work fine?

Several possibilities come to mind. You can read more than you wanted to know about FLAC at https://xiph.org/flac/index.html and there is always the flac -t command at your disposal. There are other diagnostic tools as well.

However, probably the quickest way forward is to zip up one or two of the track files known to throw these errors, upload the zip file to your Google Drive, dropbox.com, or similar, and send a private message containing a link to the file to me, @Nutul , and @Tim Curtis. One or more of us will get back to you with what we find.

Kent

Thanks Kent, I’ll read up first on the FLAC standard via the link you suggested and try and relate that to messages in my system log.
