[Android Apps and Games] Snowknight26:
BubbleUPnP Server definitely has an issue. When viewing a foobar2000 autoplaylist of recently-added tracks via foo_upnp -> BubbleUPnP Server, BubbleUPnP Server creates an image for each track, not for each album. If I recently added an album that happens to have 50 tracks but only one album art (the underlying filesystem file is the exact same image), BubbleUPnP Server will transcode the artwork once for every track.

Notice the duplicate MD5s in the first column. 03894d90a7fcaae87ff250acdd67f4d2 is listed 6 times because it's an album with 6 tracks. BubbleUPnP's transcoded images are identical.

This shouldn't be the case and BubbleUPnPServer.exe consumes far more CPU time than it should.
