How to manage delayed playbacks
Audio DJ Studio for .NET allows setting up a list of sound files whose playback can be programmed to start after a given delay through a set of methods of the DelayedPlaybackMan class.
Each sound file (item) can be added to the list of delayed playbacks through the DelayedPlayback.ListAddItem method which will return back a unique identifier that will be then used in order to access the item itself.
The number of items inside the list can be enumerated through the DelayedPlayback.ListGetCount method.
If time positioning and duration of a certain item should overlap with the time positioning and duration of an existing item, you could decide if accepting or denying its insertion inside the list through the DelayedPlayback.AllowOverlapping property: if overlapping shouldn't be allowed, an ERR_DELAYED_PLAYBACK_OVERLAP error would be generated in case of overlapping. Note that, in case of overlapping, the playing song would be immediately stopped without any kind of fade-out when an overlapped song should be started.
As already mentioned, each item is identified through its unique identifier: this identifier is passed as a parameter for accessing the following item's related features:
Delayed playbacks are mainly intended for usage with regular audio files so encrypted audio files and video clips are not supported directly. A possible trick for using encrypted audio files and video clips with delayed playback would be the following:
As you may understand, with this trick there would be no possibility to add more than one single file to the list of delayed playbacks for the involved player.
