DefaultAudioTrackBufferSizeProvider

Provide the buffer size to use when creating an AudioTrack.

Provides the buffer size to use when creating an AudioTrack.

Summary

Constants
`const DefaultAudioSink.AudioTrackBufferSizeProvider!`	`DEFAULT` Default instance.

Public functions
`Int`	`getBufferSizeInBytes( minBufferSizeInBytes: Int, @C.Encoding encoding: Int, @DefaultAudioSink.OutputMode outputMode: Int, pcmFrameSize: Int, sampleRate: Int, bitrate: Int, maxAudioTrackPlaybackSpeed: Double )` Returns the buffer size to use when creating an `AudioTrack` for a specific format and output mode.

Constants

DEFAULT

const val DEFAULT: DefaultAudioSink.AudioTrackBufferSizeProvider!

Default instance.

Public functions

getBufferSizeInBytes

fun getBufferSizeInBytes(
    minBufferSizeInBytes: Int,
    @C.Encoding encoding: Int,
    @DefaultAudioSink.OutputMode outputMode: Int,
    pcmFrameSize: Int,
    sampleRate: Int,
    bitrate: Int,
    maxAudioTrackPlaybackSpeed: Double
): Int

Returns the buffer size to use when creating an AudioTrack for a specific format and output mode.

Parameters
`minBufferSizeInBytes: Int`	The minimum buffer size in bytes required to play this format. See `getMinBufferSize`.
`@C.Encoding encoding: Int`	The `C.Encoding` of the format.
`@DefaultAudioSink.OutputMode outputMode: Int`	How the audio will be played. One of the `output modes`.
`pcmFrameSize: Int`	The size of the PCM frames if the `encoding` is PCM, 1 otherwise, in bytes.
`sampleRate: Int`	The sample rate of the format, in Hz.
`bitrate: Int`	The bitrate of the audio stream if the stream is compressed, or `NO_VALUE` if `encoding` is PCM or the bitrate is not known.
`maxAudioTrackPlaybackSpeed: Double`	The maximum speed the content will be played using `setPlaybackParams`. 0.5 is 2x slow motion, 1 is real time, 2 is 2x fast forward, etc. This will be `1` unless `setEnableAudioTrackPlaybackParams` is enabled.

Returns
`Int`	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`.
