I am migrating my Plex server from a QNAP NAS to a CentOS PC, and saw some missing music. The crux of the issue comes from the error (reproducible by triggering a metadata refresh on the music library):

ERROR - [FFMPEG] - Header processing failed: Invalid data found when processing input
ERROR - Match: Caught exception opening file: Could not parse /real/path/to/music.ogg (error=-1094995529): Invalid data found when processing input

I have verified that the file is accessible to the Plex server’s user ID, and that the file is actually OK (vorbiscomment command reports correct info., and a desktop player plays the files OK).

If I visit one of the files in question in Plex, the get info option still shows the path pre-migration, although I guess that is to be expected.

Maybe tellingly, the issue applies to all files in two related albums I would have ripped at the same time. I see one other (whole) album exhibiting that problem, but only those.

It does sort of feel like a permissions error, but I’ve definitely run vorbiscomment and file on the files as the Plex user.

I have been able to replicate this directly with ffmpeg, so it’s arguably not Plex’s issue (not sure why [if?[ is was OK on the NAS, maybe it wasn’t and had just kept the metadata from an older scanner).

I am unable to make ffmpeg work with them, even after deleting all comments. I may have to re-rip the buggers.
