long elapsedRealtimeMs

elapsedRealtime when the load attempts to start.
long loadDurationMs

The duration in milliseconds of the load since startLoading was called.
int retryCount

The number of failed attempts since startLoading was called (this is zero for the first load attempt).

releasePeriod

public void releasePeriod(MediaPeriod mediaPeriod)

Releases the period.

Should not be called directly from application code.

This method must be called on the playback thread.

Parameters
MediaPeriod mediaPeriod

Protected methods

prepareSourceInternal

protected void prepareSourceInternal(@Nullable TransferListener mediaTransferListener)

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

This method is called on the playback thread.

Parameters
@Nullable TransferListener mediaTransferListener

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.
