• setVideoEffects

  @CanIgnoreReturnValue
  @Deprecated
  public Transformer.Builder setVideoEffects​(List<Effect> effects)

  Deprecated.

  Set the video effects in an EditedMediaItem, and pass it to Transformer.start(EditedMediaItem, String) instead.

• setRemoveAudio

  @CanIgnoreReturnValue
  @Deprecated
  public Transformer.Builder setRemoveAudio​(boolean removeAudio)

  Deprecated.

  Use EditedMediaItem.Builder.setRemoveAudio(boolean) to remove the audio from the EditedMediaItem passed to Transformer.start(EditedMediaItem, String) instead.

• setRemoveVideo

  @CanIgnoreReturnValue
  @Deprecated
  public Transformer.Builder setRemoveVideo​(boolean removeVideo)

  Use EditedMediaItem.Builder.setRemoveVideo(boolean) to remove the video from the EditedMediaItem passed to Transformer.start(EditedMediaItem, String) instead.

• setFlattenForSlowMotion

  @CanIgnoreReturnValue
  @Deprecated
  public Transformer.Builder setFlattenForSlowMotion​(boolean flattenForSlowMotion)

  Deprecated.

  Use EditedMediaItem.Builder.setFlattenForSlowMotion(boolean) to flatten the EditedMediaItem passed to Transformer.start(EditedMediaItem, String) instead.

• setListener

  @CanIgnoreReturnValue
  @Deprecated
  public Transformer.Builder setListener​(Transformer.Listener listener)

  Deprecated.

  Use addListener(Listener), removeListener(Listener) or removeAllListeners() instead.

• addListener

  @CanIgnoreReturnValue
  public Transformer.Builder addListener​(Transformer.Listener listener)

  Adds a Transformer.Listener to listen to the export events.

  This is equivalent to Transformer.addListener(Listener).

  Parameters:

  listener - A Transformer.Listener.

  Returns:

  This builder.

• removeListener

  @CanIgnoreReturnValue
  public Transformer.Builder removeListener​(Transformer.Listener listener)

  Removes a Transformer.Listener.

  This is equivalent to Transformer.removeListener(Listener).

  Parameters:

  listener - A Transformer.Listener.

  Returns:

  This builder.

• removeAllListeners

  @CanIgnoreReturnValue
  public Transformer.Builder removeAllListeners()

  Removes all listeners.

  This is equivalent to Transformer.removeAllListeners().

  Returns:

  This builder.

• setAssetLoaderFactory

  @CanIgnoreReturnValue
  public Transformer.Builder setAssetLoaderFactory​(AssetLoader.Factory assetLoaderFactory)

  Sets the AssetLoader.Factory to be used to retrieve the samples to export.

  The default value is a DefaultAssetLoaderFactory built with a DefaultMediaSourceFactory and a DefaultDecoderFactory.

  Parameters:

  assetLoaderFactory - An AssetLoader.Factory.

  Returns:

  This builder.

• setVideoFrameProcessorFactory

  @CanIgnoreReturnValue
  public Transformer.Builder setVideoFrameProcessorFactory​(VideoFrameProcessor.Factory videoFrameProcessorFactory)

  Sets the factory to be used to create VideoFrameProcessor instances.

  The default value is a DefaultVideoFrameProcessor.Factory built with default values.

  Parameters:

  videoFrameProcessorFactory - A VideoFrameProcessor.Factory.

  Returns:

  This builder.

• setEncoderFactory

  @CanIgnoreReturnValue
  public Transformer.Builder setEncoderFactory​(Codec.EncoderFactory encoderFactory)

  Sets the Codec.EncoderFactory that will be used by the transformer.

  The default value is a DefaultEncoderFactory instance.

  Parameters:

  encoderFactory - The Codec.EncoderFactory instance.

  Returns:

  This builder.

• setMuxerFactory

  @CanIgnoreReturnValue
  public Transformer.Builder setMuxerFactory​(Muxer.Factory muxerFactory)

  Sets the factory for muxers that write the media container.

  The default value is a DefaultMuxer.Factory.

  Parameters:

  muxerFactory - A Muxer.Factory.

  Returns:

  This builder.

• setLooper

  @CanIgnoreReturnValue
  public Transformer.Builder setLooper​(Looper looper)

  Sets the Looper that must be used for all calls to the transformer and that is used to call listeners on.

  The default value is the Looper of the thread that this builder was created on, or if that thread does not have a Looper, the Looper of the application's main thread.

  Parameters:

  looper - A Looper.

  Returns:

  This builder.

• setDebugViewProvider

  @CanIgnoreReturnValue
  public Transformer.Builder setDebugViewProvider​(DebugViewProvider debugViewProvider)

  Sets a provider for views to show diagnostic information (if available) during export.

  This is intended for debugging. The default value is DebugViewProvider.NONE, which doesn't show any debug info.

  Not all exports will result in debug views being populated.

  Parameters:

  debugViewProvider - Provider for debug views.

  Returns:

  This builder.

• build

  public Transformer build()

  Builds a Transformer instance.

  Throws:

  IllegalStateException - If both audio and video have been removed (otherwise the output would not contain any samples).

  IllegalStateException - If the muxer doesn't support the requested audio/video MIME type.
