@Deprecated public interface AudioSink
Deprecated.com.google.android.exoplayer2 is deprecated. Please migrate to androidx.media3 (which contains the same ExoPlayer code). See the migration guide for more details, including a script to help with the migration.A sink that consumes audio data.Before starting playback, specify the input audio format by calling
configure(Format, int, int[])
.Call
handleBuffer(ByteBuffer, long, int)
to write data, andhandleDiscontinuity()
when the data being fed is discontinuous. Callplay()
to start playing the written data.Call
configure(Format, int, int[])
whenever the input format changes. The sink will be reinitialized on the next call tohandleBuffer(ByteBuffer, long, int)
.Call
flush()
to prepare the sink to receive audio data from a new playback position.Call
playToEndOfStream()
repeatedly to play out all data when no more input buffers will be provided viahandleBuffer(ByteBuffer, long, int)
until the nextflush()
. Callreset()
when the instance is no longer required.The implementation may be backed by a platform
AudioTrack
. In this case,setAudioSessionId(int)
,setAudioAttributes(AudioAttributes)
,enableTunnelingV21()
anddisableTunneling()
may be called before writing data to the sink. These methods may also be called after writing data to the sink, in which case it will be reinitialized as required. For implementations that are not based on platformAudioTrack
s, calling methods relating to audio sessions, audio attributes, and tunneling may have no effect.

to leave the input unchanged. Otherwise, the element at indexi
specifies index of the input channel to map to output channeli
when preprocessing input buffers. After the map is applied the audio data will haveoutputChannels.length
channels.- Throws:

handleBuffer
boolean handleBuffer(ByteBuffer buffer, long presentationTimeUs, int encodedAccessUnitCount) throws AudioSink.InitializationException, AudioSink.WriteException
Deprecated.Attempts to process data from aByteBuffer
, starting from its current position and ending at its limit (exclusive). The position of theByteBuffer
is advanced by the number of bytes that were handled.AudioSink.Listener.onPositionDiscontinuity()
will be called ifpresentationTimeUs
is discontinuous with the last buffer handled since the last reset.Returns whether the data was handled in full. If the data was not handled in full then the same
ByteBuffer
must be provided to subsequent calls until it has been fully consumed, except in the case of an intervening call toflush()
(or toconfigure(Format, int, int[])
that causes the sink to be flushed).- Parameters:
