Struct AudioPlayer 

pub struct AudioPlayer { /* private fields */ }

Rust wrapper for Android audio player

Implementations

impl AudioPlayer

pub fn new( env: JNIEnv<'_>, context: &GlobalRef, sample_rate: SampleRate, channel_config: ChannelOutConfig, audio_format: AudioEncoding, mode: PlayerMode, ) -> Result<Self, PlayerError>

Create a new AudioPlayer instance

Arguments

• env - JNI environment
• context - GlobalRef to context object (used to get the correct ClassLoader)
• sample_rate - Sample rate (e.g., SampleRate::Rate16000)
• channel_config - Channel configuration (ChannelOutConfig::Mono or ChannelOutConfig::Stereo)
• audio_format - Audio encoding format (AudioEncoding::Pcm8bit, AudioEncoding::Pcm16bit, or AudioEncoding::PcmFloat)
• mode - Playback mode (PlayerMode::Static or PlayerMode::Stream)

Returns

Returns initialized AudioPlayer instance

Examples

See the README.md for complete usage examples.

pub fn play(&self) -> Result<(), PlayerError>
