Skin.arctic.horizon: [Question]

Doesn't that do the same thing as "Update Library" which is already in the menu?

It’s a bit hard to explain but I’ll try my best.

The problem with update library it will perform a full scan(tv shows & movies) This can take a while if you have a large library.

tv shows library: Scan for new content only scans the individual tvshow.

Video source has the option to “scan for new content” for tv shows or movies etc. this is very fast because it only detects newly added tv shows or episodes.

Ah, of course! You only want to scan the specific source to cut down on the update time. Sadly, I don't think it is possible from the skin side of things.

The "Scan for new content" is the same command as UpdateLibrary(video,sourcepath) -- It just specifies the folder location for update library so that it only scans that one particular folder.

The problem is that TVShows section of the library can be made up of multiple sources split into different folders but all those sources can be shown mixed together in the one tvshow library node, so you would need a separate command for each source: e.g.
UpdateLibrary(video,/storage/videos/tvshows/)
UpdateLibrary(video,/storage/videos/documentaries/)
UpdateLibrary(video,/storage/videos/cartoons/)
etc.

There's not really any way for the skin to get thesesources that make up the library node - the skin only sees the virtual path to the node e.g. videodb://tvshows/titles and that won't work because it doesn't map to a specific folder location on the hard-drive.

It's almost unbelievable someone never thought of this feature.
I'll have to rely on the watchdog add-on for now. it's very good and fully automated but has not been updated for years. It puts a very heavy load on the cpu and causes Kodi to crash when existing Kodi. Are you familiar with this add-on?

Update:
I don't know when it was updated. Kodi can now scan for new content in the default library 😀
