getBufferSizeInBytes

int getBufferSizeInBytes​(int minBufferSizeInBytes,
                         @com.google.android.exoplayer2.C.Encoding int encoding,
                         @com.google.android.exoplayer2.audio.DefaultAudioSink.OutputMode int outputMode,
                         int pcmFrameSize,
                         int sampleRate,
                         int bitrate,
                         double maxAudioTrackPlaybackSpeed)

Returns the buffer size to use when creating an AudioTrack for a specific format and output mode. Parameters:minBufferSizeInBytes - The minimum buffer size in bytes required to play this format. See AudioTrack.getMinBufferSize(int, int, int).encoding - The C.Encoding of the format.outputMode - How the audio will be played. One of the output modes.pcmFrameSize - The size of the PCM frames if the encoding is PCM, 1 otherwise, in bytes.sampleRate - The sample rate of the format, in Hz.bitrate - The bitrate of the audio stream if the stream is compressed, or Format.NO_VALUE if encoding is PCM or the bitrate is not known.maxAudioTrackPlaybackSpeed - The maximum speed the content will be played using AudioTrack.setPlaybackParams(android.media.PlaybackParams). 0.5 is 2x slow motion, 1 is real time, 2 is 2x fast forward, etc. This will be 1 unless DefaultAudioSink.Builder.setEnableAudioTrackPlaybackParams(boolean) is enabled.Returns:The computed buffer size in bytes. It should always be >= minBufferSizeInBytes. The computed buffer size must contain an integer number of frames: bufferSizeInBytes % pcmFrameSize == 0.
