customizedCloudStatusCallback

nullable function(non-null cast.receiver.media.CloudMediaStatus) returns (nullable cast.receiver.media.CloudMediaStatus or Promise containing nullable cast.receiver.media.CloudMediaStatus)

The application developer can provide a different media status for cloud sender. This hanlder will be called with a copy of the media status that is sent to all other senders, after the customizedStatusCallback handler is called. If the method returns null the media status message will not be sent

customizedStatusCallback

nullable function(non-null cast.receiver.media.MediaStatus) returns (nullable cast.receiver.media.MediaStatus or Promise containing nullable cast.receiver.media.MediaStatus)

The application developer can override this method to customize the media status that will be send to the senders (this method will be called before the media status is sent). By providing this method application developers can, for example, add custom data to the media status. The current media status will be provided as a parameter and the method should return the application-modified current status. The default behavior is to return the incoming media status. If the method returns null the media status message will not be sent (developers should be aware that if the media status is a response to a sender status request the sender will expect a response so this method should only return null it if the developer is also overriding onGetStatus).

onAbort

nullable function()

Called when the current media is terminated before reaching the end due to a sender request (for example, the current element of the queue is deleted). The default behavior is to call ResetMediaElement with idle reason. INTERRUPTED.

See also

cast.receiver.media.IdleReason

onCancelPreload

nullable function(non-null cast.receiver.MediaManager.Event) returns boolean

Called when there is a CANCEL_PRELOAD event. This can happen if the user has seek before the time that the preload is triggered or if the next item in the queue has changed and has a shorter preload time. By default is null. If implemented, the callee is supposed to return true if media will be cancelled its preloaded or false otherwise. This information will be used to send a media status message to the senders so they can update the second screen UI.

onLoad

nullable function(non-null cast.receiver.MediaManager.Event)

If provided, it processes the LOAD event. The default behavior is to set the src and autoplay properties of the media element and call its load method. If provided, the currentTime property will be modified when the 'loadedmetadata' event is fired (in onMetadataLoaded) as it can only be set when the media element duration property has been set. If this method is overriden, the application developer may need to handle sendLoadError, sendLoadComplete and onMetadataLoaded. Please read the documentation of those APIs.

It is the applications responsibility to deserialize the string.

onPreload

nullable function(non-null cast.receiver.MediaManager.Event) returns boolean

Called when there is a PRELOAD event. By default is null. If implemented, the callee is supposed to return true if media will be preloaded or false, otherwise. This information will be used to send a media status message to the senders so they can update the second screen UI.

cast.receiver.MediaManager.Event

cast.receiver.MediaManager.PreloadRequestData

onQueueEnded

nullable function(non-null cast.receiver.media.IdleReason, optional nullable number)

Called when the last item ends or is aborted (playback of the queue completes). Takes two params, the idleReason and optionally the requestId. The default behavior is to call ResetMediaElement with idle reason FINISHED. If the application wants to keep the media session alive after playback of the queue has been completed, the application should override this event callback with a function that modifies the queue so that there are more items to play (for example, by appending new items to the queue).

getSupportedMediaCommands

getSupportedMediaCommands() returns number

Get receiver supported media commands.

See also

cast.receiver.media.Command

Returns

number A bitmask of media commands supported by the application.

insertQueueItems

insertQueueItems(itemsToInsert, opt_insertBefore, opt_currentItemIndex, opt_currentItemId, opt_currentTime)

Insert items in the queue. This is an asynchronous request that will be scheduled and processed as it was requested by a sender. Typically this request will trigger a onLocalRequestError or onMediaStatus callback.

Parameter
itemsToInsert	Array of non-null cast.receiver.media.QueueItem The list of media items to insert. Must not be null or empty. The itemId of each item must not be set (as they will be assigned by the receiver). Value must not be null.
opt_insertBefore	Optional number ID of the item that will be located immediately after the inserted list. If it is not provided or it is not found, the list will be appended to the end of the queue. Value may be null.
opt_currentItemIndex	Optional number Index (relative to the items array, starting with 0) of the new currentmedia Item. Value may be null.
opt_currentItemId	Optional number ID of the current media Item after the insertion (if not provided, the currentItem value will be the same as before the insertion). Value may be null.

Loads a media session on the receiver without involvement of a sender.

Parameter
loadRequestData	cast.receiver.MediaManager.LoadRequestData The load request data. Value must not be null.

loadTracksInfo

loadTracksInfo(tracksInfo) returns boolean

Allows to load tracks if load is still ongoing. This method is useful if the application wants to override onLoad but still wants to use the default behavior for tracks handling. For example, this can be useful if the application has to override onLoad to support HLS but it is using vtt closed captions. Note that if the mediaManager is no longer in the loading state the request will be ignored.

Parameter
tracksInfo	cast.receiver.media.TracksInfo The tracks info. Value must not be null.

Returns

boolean Whether the tracks are valid and the tracks load request was honored.

queueLoad

queueLoad(queueLoadRequestData)

Loads a queue on the receiver without involvement of a sender.

Parameter
queueLoadRequestData	cast.receiver.MediaManager.QueueLoadRequestData Queue load request data. Value must not be null.

removeQueueItems

removeQueueItems(itemIdsToRemove, opt_currentItemId, opt_currentTime)

Removes a list of items from the queue. If the remaining queue is empty, the media session will be terminated. This is an asynchronous request that will be scheduled and processed as it was requested by a sender. Typically this request will trigger a onLocalRequestError or onMediaStatus callback.

Parameter
itemIdsToRemove	Array of number The list of media item IDs to remove. Must not be null or empty. Value must not be null.
opt_currentItemId	Optional number ID of the current media Item after the deletion (if not provided, the currentItem value will be the same as before the deletion; if it does not exist because it has been deleted, the currentItem will point to the next logical item in the list). Value may be null.
opt_currentTime	Optional number Seconds since the beginning of content to start playback of the current item. If provided, this value will take precedence over the startTime value provided at the QueueItem level. Value may be null.

removeSupportedMediaCommands(supportedMediaCommands, broadcastStatus)

Remove commands from receiver supported media commands.

Parameter
supportedMediaCommands	number A bitmask of media commands supported by the application.
broadcastStatus	Optional boolean Whether the senders should be notified about the change (if not provided, the senders will be notified).

See also

cast.receiver.media.Command

resetMediaElement

resetMediaElement(opt_idleReason, opt_broadcast, opt_requestId, opt_broadcastStatusCustomData)

Resets Media Element to IDLE state. After this call the mediaElement properties will change, paused will be true, currentTime will be zero and the src attribute will be empty. This only needs to be manually called if the developer wants to override the default behavior of onError, onStop or onEnded, for example.

Parameter
opt_idleReason	Optional cast.receiver.media.IdleReason The reason to be IDLE. Value must not be null.
opt_broadcast	Optional boolean Whether the senders should be notified about the change (if not provided, the senders will be notified).
opt_requestId	Optional number If the status change is due to a sender request (for example, STOP), this is the ID of the sender request that will be added to the status message so the sender can identify it. Value may be null.
opt_broadcastStatusCustomData	Optional Object If the senders should be notified, this parameter allows to set the application-specific custom data in the status message. Value may be null.

Throws

Error If opt_broadcastStatusCustomData is provided but opt_broadcast is false.

sendError

sendError(senderId, requestId, type, reason, customData, detailedErrorCode, itemId)

Sends an error to a specific sender.

Parameter
senderId	string The sender ID.
requestId	(number or undefined) The ID of the incoming request that caused this error.
type	cast.receiver.media.ErrorType The error type. Value must not be null.
reason	Optional cast.receiver.media.ErrorReason The error reason. Value may be null.
customData	Optional Object The error message application-specific custom data. Value may be null.
detailedErrorCode	Optional number Optional detailed error code.
itemId	Optional number Optional queue item id that had the error.

sendLoadComplete

sendLoadComplete(opt_customData)

Sends the new status after a LOAD message has been completed successfully. Note: Applications do not normally need to call this API. When the application overrides onLoad, it may need to manually declare that the LOAD request was successful. The default implementaion will send the new status to the sender when the video/audio element raises the 'loadedmetadata' event. The default behavior may not be acceptable in a couple scenarios:

1. When the application does not want to declare LOAD successful until, for example, 'canPlay' is raised (instead of 'loadedmetadata').
2. When the application is not actually loading the media element (for example, if LOAD is used to load an image).

Parameter
opt_customData	Optional Object The status message application-specific custom data. Value may be null.

sendLoadError

sendLoadError(errorType, customData, reason, detailedErrorCode)

When the application overrides onLoad, it should use this method to trigger an error response to the sender. This is typically due to application-specific verification issues.

Parameter
errorType	Optional cast.receiver.media.ErrorType The error type, by default is assumed to be cast.receiver.media.ErrorType.LOAD_FAILED, but the application can send an INVALID_REQUEST, for example, if there is customData that does not match some criteria. Value may be null.
customData	Optional Object The error message application-specific custom data. Value may be null.
reason	Optional cast.receiver.media.ErrorReason The error reason. Value must not be null.
detailedErrorCode	Optional number Detailed error code.

See also

cast.receiver.media.ErrorType

sendStatus

sendStatus(senderId, requestId, includeMedia, opt_customData, opt_includeQueueItems)

Sends a media status message to a specific sender.

Parameter
senderId	string The sender ID.
requestId	number The ID of the incoming request that caused this response.
includeMedia	boolean Whether to include media information.
opt_customData	Optional Object The status message application-specific custom data. Value may be null.
opt_includeQueueItems	Optional boolean Whether to include queue items in the status message. By default they are not included.

sendStoreSessionResponse

sendStoreSessionResponse(senderId, requestId, sessionState)

Send a StoreSessionResponseData

Parameter
senderId	string The sender ID.
requestId	number The ID of the incoming request that caused this response.
sessionState	cast.receiver.MediaManager.SessionState The state object you want to store. Value must not be null.

setIdleReason

setIdleReason(idleReason)

Sets the IDLE reason. This allows applications that want to force the IDLE state to indicate the reason that made the player going to IDLE state (a custom error, for example). The idle reason will be sent in the next status message. NOTE: Most applications do not need to set this value, it is only needed if they want to make the player go to IDLE in special circumstances and the default idleReason does not reflect their intended behavior.

Parameter
idleReason	cast.receiver.media.IdleReason The reason to be in the IDLE state. Value must not be null.

setMediaElement

setMediaElement(mediaElement)

Associates a new media element or Player to the media manager.

Parameter
mediaElement	(non-null HTMLMediaElement or non-null cast.receiver.media.Player) The DOM media element (video/audio) or a player that implements the cast.receiver.media.Player interface.

setMediaInformation

setMediaInformation(mediaInformation, opt_broadcast, opt_broadcastStatusCustomData)

Sets information about the media currently loaded. This information will be sent to the senders when they request media status.

Parameter
mediaInformation	cast.receiver.media.MediaInformation The new media information. Use resetMediaElement to reset its value. Value must not be null.
opt_broadcast	Optional boolean Whether the senders should be notified about the change (if not provided, the senders will be notified).
opt_broadcastStatusCustomData	Optional Object If the senders should be notified this parameter allows to set the application-specific custom data in the status message. Value must not be null.

See also

cast.receiver.media.MediaInformation

Throws

Error If opt_broadcastStatusCustomData is provided but opt_broadcast is false.

setSupportedMediaCommands

setSupportedMediaCommands(supportedMediaCommands, broadcastStatus)

Set receiver supported media commands.

Parameter
supportedMediaCommands	number A bitmask of media commands supported by the application.
broadcastStatus	Optional boolean Whether the senders should be notified about the change (if not provided, the senders will be notified).

See also

cast.receiver.media.Command

updatePlaybackRate

updatePlaybackRate(playbackRate)

Update the current playback rate. Media manager needs to know the current playback rate to check time drift so an overwriten onSetPlaybackRate or onLoad handlers should use this function to report back the playback rate.

Parameter
playbackRate	number The update playback rate.
