Method Detail

• prepareSourceInternal

  @CallSuper
  protected void prepareSourceInternal​(@Nullable
                                       TransferListener mediaTransferListener)

  Description copied from class: BaseMediaSource
  Starts source preparation and enables the source, see BaseMediaSource.prepareSource(MediaSourceCaller, TransferListener). This method is called at most once until the next call to BaseMediaSource.releaseSourceInternal().

  Specified by:

  prepareSourceInternal in class BaseMediaSource

  Parameters:

  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.

• maybeThrowSourceInfoRefreshError

  @CallSuper
  public void maybeThrowSourceInfoRefreshError()
                                        throws IOException

  Description copied from interface: MediaSource
  Throws any pending error encountered while loading or refreshing source information.

  Should not be called directly from application code.

  Must only be called after MediaSource.prepareSource(MediaSourceCaller, TransferListener).

  Throws:

  IOException

• enableInternal

  @CallSuper
  protected void enableInternal()

  Description copied from class: BaseMediaSource
  Enables the source, see BaseMediaSource.enable(MediaSourceCaller).

  Overrides:

  enableInternal in class BaseMediaSource

• disableInternal

  @CallSuper
  protected void disableInternal()

  Description copied from class: BaseMediaSource
  Disables the source, see BaseMediaSource.disable(MediaSourceCaller).

  Overrides:

  disableInternal in class BaseMediaSource

• releaseSourceInternal

  @CallSuper
  protected void releaseSourceInternal()

  Description copied from class: BaseMediaSource
  Releases the source, see BaseMediaSource.releaseSource(MediaSourceCaller). This method is called exactly once after each call to BaseMediaSource.prepareSourceInternal(TransferListener).

  Specified by:

  releaseSourceInternal in class BaseMediaSource

• onChildSourceInfoRefreshed

  protected abstract void onChildSourceInfoRefreshed​(T id,
                                                     MediaSource mediaSource,
                                                     Timeline timeline)

  Called when the source info of a child source has been refreshed.

  Parameters:

  id - The unique id used to prepare the child source.

  mediaSource - The child source whose source info has been refreshed.

  timeline - The timeline of the child source.

• prepareChildSource

  protected final void prepareChildSource​(T id,
                                          MediaSource mediaSource)

  Prepares a child source.

  onChildSourceInfoRefreshed(Object, MediaSource, Timeline) will be called when the child source updates its timeline with the same id passed to this method.

  Any child sources that aren't explicitly released with releaseChildSource(Object) will be released in releaseSourceInternal().

  Parameters:

  id - A unique id to identify the child source preparation. Null is allowed as an id.

  mediaSource - The child MediaSource.

• enableChildSource

  protected final void enableChildSource​(T id)

  Enables a child source.

  Parameters:

  id - The unique id used to prepare the child source.

• disableChildSource

  protected final void disableChildSource​(T id)

  Disables a child source.

  Parameters:

  id - The unique id used to prepare the child source.

• releaseChildSource

  protected final void releaseChildSource​(T id)

  Releases a child source.

  Parameters:

  id - The unique id used to prepare the child source.

• getWindowIndexForChildWindowIndex

  protected int getWindowIndexForChildWindowIndex​(T id,
                                                  int windowIndex)

  Returns the window index in the composite source corresponding to the specified window index in a child source. The default implementation does not change the window index.

  Parameters:

  id - The unique id used to prepare the child source.

  windowIndex - A window index of the child source.

  Returns:

  The corresponding window index in the composite source.

• getMediaPeriodIdForChildMediaPeriodId

  @Nullable
  protected MediaSource.MediaPeriodId getMediaPeriodIdForChildMediaPeriodId​(T id,
                                                                            MediaSource.MediaPeriodId mediaPeriodId)

  Returns the MediaSource.MediaPeriodId in the composite source corresponding to the specified MediaSource.MediaPeriodId in a child source. The default implementation does not change the media period id.

  Parameters:

  id - The unique id used to prepare the child source.

  mediaPeriodId - A MediaSource.MediaPeriodId of the child source.

  Returns:

  The corresponding MediaSource.MediaPeriodId in the composite source. Null if no corresponding media period id can be determined.

• getMediaTimeForChildMediaTime

  protected long getMediaTimeForChildMediaTime​(T id,
                                               long mediaTimeMs)

  Returns the media time in the composite source corresponding to the specified media time in a child source. The default implementation does not change the media time.

  Parameters:

  id - The unique id used to prepare the child source.

  mediaTimeMs - A media time of the child source, in milliseconds.

  Returns:

  The corresponding media time in the composite source, in milliseconds.
