| This parameter is only used for prelisten channels. You can specify the GUI numbers (as a comma-separated list) of GUIs which uses this channel for prelistening. See the chapter about prelistening and PFL in the TurboPlayer technical manual. Warning: if you do not specify a GUI parameter at all, all known GUIs are automatically assigned to the first prelisten channel. If you have at least one GUI parameter, every GUI which wants to use the engine prelisten must be listed, otherwise the GUI cannot start an engine prelisten. |
