Method Detail

• setListener

  @NonNull() TranscoderOptions.Builder setListener(@NonNull() TranscoderListener listener)

• setListenerHandler

  @NonNull() TranscoderOptions.Builder setListenerHandler(@Nullable() Handler listenerHandler)

  Sets an handler for TranscoderListener callbacks.If null, this will default to the thread that starts the transcoding, if ithas a looper, or the UI thread otherwise.

  Parameters:

  listenerHandler - the thread to receive callbacks

• setAudioTrackStrategy

  @NonNull() TranscoderOptions.Builder setAudioTrackStrategy(@Nullable() TrackStrategy trackStrategy)

  Sets the audio output strategy. If absent, this defaults to com.otaliastudios.transcoder.strategy.DefaultAudioStrategy.

  Parameters:

  trackStrategy - the desired strategy

• setVideoTrackStrategy

  @NonNull() TranscoderOptions.Builder setVideoTrackStrategy(@Nullable() TrackStrategy trackStrategy)

  Sets the video output strategy. If absent, this defaults to the 16:9strategy returned by for720x1280.

  Parameters:

  trackStrategy - the desired strategy

• setValidator

  @NonNull() TranscoderOptions.Builder setValidator(@Nullable() Validator validator)

  Sets a validator to understand whether the transcoding process shouldstop before being started, based on the tracks status. Will default to com.otaliastudios.transcoder.validator.DefaultValidator.

  Parameters:

  validator - the validator

• setVideoRotation

  @NonNull() TranscoderOptions.Builder setVideoRotation(int rotation)

  The clockwise rotation to be applied to the input video frames.Defaults to 0, which leaves the input rotation unchanged.

  Parameters:

  rotation - either 0, 90, 180 or 270

• setTimeInterpolator

  @NonNull() TranscoderOptions.Builder setTimeInterpolator(@NonNull() TimeInterpolator timeInterpolator)

  Sets a TimeInterpolator to change the frames timestamps - either video oraudio or both - before they are written into the output file.Defaults to com.otaliastudios.transcoder.time.DefaultTimeInterpolator.

  Parameters:

  timeInterpolator - a time interpolator

• setAudioStretcher

  @NonNull() TranscoderOptions.Builder setAudioStretcher(@NonNull() AudioStretcher audioStretcher)

  Sets an AudioStretcher to perform stretching of audio samplesas a consequence of speed and time interpolator changes.Defaults to DefaultAudioStretcher.

  Parameters:

  audioStretcher - an audio stretcher

• setAudioResampler

  @NonNull() TranscoderOptions.Builder setAudioResampler(@NonNull() AudioResampler audioResampler)

  Sets an AudioResampler to change the sample rate of audioframes when sample rate conversion is needed. Upsampling is discouraged.Defaults to DefaultAudioResampler.

  Parameters:

  audioResampler - an audio resampler

• setSpeed

  @NonNull() TranscoderOptions.Builder setSpeed(float speedFactor)

  Shorthand for calling setTimeInterpolator and passing a com.otaliastudios.transcoder.time.SpeedTimeInterpolator.This interpolator can modify the video speed by the given factor.

  Parameters:

  speedFactor - a factor, greather than 0

• build

  @NonNull() TranscoderOptions build()

• transcode

  @NonNull() Future<Void> transcode()
