OptionaldeferredStart the playback after the current message has been handled instead of before the call returns. The playlist is looked up again by its GUID when the playback starts: moved meanwhile, the same playlist plays; removed meanwhile, or shorter than index by then, nothing plays.
OptionalexpectedExpected content version for optimistic concurrency control. When mismatched, mutations are aborted with STALE_TARGET (details.current carries current version). Omitted, no check is made.
OptionalindexRow to play.
OptionalmutedMute before starting, so a page that sets the volume right afterwards leaves no audible gap. The mute is not undone by this call.
OptionalplaylistIndex of the playlist; omitted, the active playlist. An index past the last playlist fails with INVALID_INDEX; with this omitted and no active playlist the call fails with NO_ACTIVE_ITEM.
OptionalplaylistPersistent unique identifier of a playlist (bracketed GUID, case-insensitive), used in place of a mutable index. Mutually exclusive with playlist; passing both or an invalid format fails with INVALID_PARAMS. Fails with NOT_FOUND if the playlist does not exist, never falling back. Invalid-format and not-found failures return the given GUID in details.playlistGuid.
Parameters for
playlist.playTrack. Play a row of a playlist, as double-clicking it does. A row past the last one fails withINVALID_INDEX. Withdeferred,expectedVersionis verified again before starting playback; if rows changed in between, playback is skipped.
