Sync DB

[geoffishere 0]

Hi

 

I had an issue with my library db (playback of files had stopped) i fixed this by deleting the library db and letting it rebuild.

 

I am now getting this error when trying to run the convert media task.

 

Convert media failed.

Object reference not set to an instance of an object

 

 I am guessing that there is something in the sync db that emby doesn't like. The log is showing

I was thinking of just deleting the sync db but i am guessing this will have a knock on affect on the currently synced media.

 

Can i delete the db to fix the error and if so will i need to manually delete the already synced media

 

Many thanks

The sync.db is probably now pointing to a media uuid that doesn't exist anymore in library.db.

I will add a null check in that method, thanks.
