Examples with AudioSink androidx.media3.exoplayer.audio.AudioSink used on opensource projects

Example 1 with AudioSink

use of androidx.media3.exoplayer.audio.AudioSink in project media by androidx.

the class DefaultRenderersFactory method buildAudioRenderers.

/**
 * Builds audio renderers for use by the player.
 *
 * @param context The {@link Context} associated with the player.
 * @param extensionRendererMode The extension renderer mode.
 * @param mediaCodecSelector A decoder selector.
 * @param enableDecoderFallback Whether to enable fallback to lower-priority decoders if decoder
 *     initialization fails. This may result in using a decoder that is slower/less efficient than
 *     the primary decoder.
 * @param audioSink A sink to which the renderers will output.
 * @param eventHandler A handler to use when invoking event listeners and outputs.
 * @param eventListener An event listener.
 * @param out An array to which the built renderers should be appended.
