This is for remembering the last selected audio or subtitle track for IPTV services.
I know there is a plugin for AutoAudioSelection but it relies on rules only and can not remember the actual user selection.
Where is needed that? Well for IPTV services that are DVB compliant and have multiple audio or subtitle tracks. Now it can not behave like the real DVB service regarding audio and subtitle user selections.
This change fix/add that functionality.
