@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 platformAudioTracks, calling methods relating to audio sessions, audio attributes, and tunneling may have no effect.

static final int SINK_FORMAT_SUPPORTED_DIRECTLY
Deprecated.The sink supports the format directly, without the need for internal transcoding.- See Also:
- Constant Field Values
