I was looking for a method to hide 4k video in a shared MySQL library on clients that did not support that format. I was hoping that there was a tag based way to accomplish this, but I could not find one. The method I did find was to use Kodi’s Media source locking in the Parental controls. The way this works is that you have a separate source for each media type you want to hide, and when you lock a source, all of the media in that source is hidden from everywhere in the library. This works an individual profile basis so what you do on one machine or user profile does not affect any others. This can also be used for other applications such as hiding certain movies from a child’s user profile or similar applications. The hidden state of the media can also be easily turned on or off from the power menu so there may be applications even for a single profile, single machine application.
