Array of Track trackIds that should be active. If the array is not
provided, the default tracks will be active.
If two incompatible trackIds are provided (for example two active audio
tracks) the command will fail with INVALID_PARAMETER.
autoplay
boolean
Whether the media will automatically play.
customData
nullable Object
Custom data set by the receiver application.
itemId
nullable number
Unique identifier of the item in the queue. If used in
chrome.cast.media.QueueLoad or chrome.cast.media.QueueInsert it must be
null (as it will be assigned by the receiver when an item is first
created/inserted). For other operations it is mandatory.
Playback duration of the item in seconds. If it is larger than the actual
duration - startTime it will be limited to the actual duration -
startTime. It can be negative, in such case the duration will be the
actual item duration minus the duration provided. A duration of value
zero effectively means that the item will not be played.
preloadTime
number
This parameter is a hint for the receiver to preload this media item
before it is played. It allows for a smooth transition between items
played from the queue.
The time is expressed in seconds, relative to
the beginning of this item playback (usually the end of the previous item
playback). Only positive values are valid. For example, if the value is
10 seconds, this item will be preloaded 10 seconds before the previous
item has finished. The receiver will try to honor this value but will not
guarantee it, for example if the value is larger than the previous item
duration the receiver may just preload this item shortly after the
previous item has started playing (there will never be two items being
preloaded in parallel). Also, if an item is inserted in the queue just
after the currentItem and the time to preload is higher than the time
left on the currentItem, the preload will just happen as soon as
possible.
startTime
number
Seconds from the beginning of the media to start playback.
