A MediaSource for server-side inserted ad breaks.

The media source publishes a Timeline for the wrapped MediaSource with the server-side inserted ad breaks and ensures that playback continues seamlessly with the wrapped media across all transitions.

The ad breaks need to be specified using setAdPlaybackStates and can be updated during playback.

Called when a load is canceled.

Parameters
`windowIndex: Int`	The window index in the timeline of the media source this load belongs to.

    error: IOException!,
    wasCanceled: Boolean
): Unit

Called when a load error occurs.

The error may or may not have resulted in the load being canceled, as indicated by the wasCanceled parameter. If the load was canceled, onLoadCanceled will not be called in addition to this method.

This method being called does not indicate that playback has failed, or that it will fail. The player may be able to recover from the error. Hence applications should not implement this method to display a user visible error or initiate an application level retry. onPlayerError is the appropriate place to implement such behavior. This method is called to provide the application with an opportunity to log the error if it wishes to do so.

Parameters
`windowIndex: Int`	The window index in the timeline of the media source this load belongs to.
`mediaPeriodId: MediaSource.MediaPeriodId?`	The `MediaPeriodId` this load belongs to. Null if the load does not belong to a specific media period.

Each period has an AdPlaybackState that tells where in the period the ad groups start and end. Must only contain server-side inserted ad groups. The number of ad groups and the number of ads within an ad group may only increase. The durations of ads may change and the positions of future ad groups may change. Post-roll ad groups with TIME_END_OF_SOURCE must be empty and can be used as a placeholder for a future ad group.

Protected functions

disableInternal

protected fun disableInternal(): Unit

Disables the source, see disable.

enableInternal

protected fun enableInternal(): Unit

Enables the source, see enable.

prepareSourceInternal

protected fun prepareSourceInternal(mediaTransferListener: TransferListener?): Unit

Starts source preparation and enables the source, see prepareSource. This method is called at most once until the next call to releaseSourceInternal.

Parameters
`mediaTransferListener: TransferListener?`	The transfer listener which should be informed of any media data transfers. May be null if no listener is available. Note that this listener should usually be only informed of transfers related to the media loads and not of auxiliary loads for manifests and other data.
