Hello, I’d like to write a quick plugin to do something for myself and a friend (it will be released eventually for the peanut gallery but for now it’s internal).
In the MyVideo’s DB and in the table ‘movie’ I’m trying to figure out what’s stored in columns c13, c16, c17, and c19.
I’d also like to know where Plex stores the ‘resume from’ numbers?
I’m not sure if you’re aware of this (since you’re fairly new here :P) but the library is undergoing a major redesign. The old databases inherited from XBMC definitely won’t survive the transition to the new system.
Sorry I can’t be more helpful - I don’t really know how the XBMC databases are structured 
I’m aware just myself and the friend who inspired this are in need of something now. As this should be rather trivial for me to create I’m not concerned about having it all ‘undone’ by library changes.
The big thing I want to know is where the position markers are stored (resume from).
VideoDatabase.h
I think the column you’re looking for is VIDEODB_ID_EPISODE_BOOKMARK
I haven’t verified this.
