Library views and Random mix preference interaction

[epoch1970]

Hi Michael ;)
I think there is an issue when setting a player to use a library view, and at the same time setting random mix to pick songs from another library view.
In this case 'playlist add randomplay://tracks' returns an empty playlist.

I had an install running fine for a long time when a single library view was defined. Then when a second one was added, empty random playlists started to crop up.
Bug or not? Anything can be done?

Cheers.

Ok, I can confirm there's some conflict: the random play plugin would extract the correct track ID, but when trying to play, the playlist addtracks command would apply the client's library, filtering out that track ID. I'm not sure yet whether this should be considered a bug in the addtracks routine, which, given a track ID, should just play that track. Or whether RandomPlay should always define what library to use...

Me again...
I think I have found another ramification of the initial problem, where random selection can be locked-down to a specific genre that doesn't exist in the library view of a player. That player will cease receiving new items for its playlist.
I have not verified the problem exists in the latest version of LMS.
I am able to work around the issue, poorly, by sending playerid randomplaygenreselectall 0 right before sending playerid playlist add randomplay://tracks. But that doesn't stick if someone uses the GUI and selects genres while the player is active.

EDIT. I looked at Mixer.pm and found I could easily unset $queryGenres in case getLibraryIdForClient() has given a value to $queryLibrary. That's enough for me.
