Unable to seek on certain files

I recently added a book with separate mp3 files for each chapter.

Some chapters report a length of zero in Prologue and, while they play fine, I am unable to seek around within the chapter. If I try to jump to a point within the chapter it just goes back to the beginning.

I am able to play the impacted chapters directly within Plex and seek around without any issues.

Is this something I could fix by doing something to the impacted file or is this a bug with Prologue?

There are some issues with VBR MP3 files in the current release version.
But the newest beta version should have fixed some of those IIRC.

Thanks. I just tested the most recent beta and it shows a length for the files now, but I still can’t seek within the file.

I’ll try to re-mux the file as mentioned in the release notes to see if that helps.

Maybe send a bug report via email to u/PrismDev, I'm sure he's interested in further fixing VBR MP3s.

Posting an update in case anyone else runs into this.

The problem was due to an incorrect timing header on the impacted files. I installed mp3val on Linux and ran mp3val -f *.mp3 and now the files work correctly without issue.

This is listed as a know issue on the most recent beta version, so this fix probably won’t be necessary in the near future.
