m4a files cause myth music lock-up

Reported by: markdavidoff@… Owned by: stuartm
Priority: minor Milestone: 0.22
Component: Plugin - MythMusic Version: 0.21

Cc: Ticket locked: no


I was importing music files using mythmusic, and it kept locking-up when it came to updating the database

I opened mythtv in verbose mode, and found that it was locking up on m4a files while trying to read the metadata.

I can attach the music file if the developers need it for debugging

I can't reproduce with trunk.

A backtrace would initially be more useful than the file -

Ok I can reproduce the problem, I just don't see an easy solution without disabling tag reading for m4a/aac. It's not a MythTV bug, it gets stuck in the mp4ff metadata library.

As a workaround you might uncheck the tag scanning option in the mythmusic settings. This will fall back to establishing artist/album/track metadata from the file path.

For trunk I'm looking at the forthcoming mp4 support in taglib, a 1.6 release isn't far away but we may also opt to keep our own copy of the library.
