Trait web_audio_api::media::MediaStream

pub trait MediaStream: Iterator<Item = Result<AudioBuffer, Box<dyn Error + Send>>> + Send + 'static { }

Interface for media decoding.

This is a trait alias for an AudioBuffer Iterator that can run in a separate thread, for example the OggVorbisDecoder

Below is an example showing how to play the stream directly.

If you want to control the media playback (play/pause, offsets, loops), wrap the MediaStream in a MediaElement.

Example

use web_audio_api::SampleRate;
use web_audio_api::context::{AudioContext, AsBaseAudioContext};
use web_audio_api::buffer::AudioBuffer;

// create a new buffer: 512 samples of silence
let silence = AudioBuffer::new(1, 512, SampleRate(44_100));

// create a sequence of this buffer
let sequence = std::iter::repeat(silence).take(5);

// the sequence should actually yield `Result<AudioBuffer, _>`s
let media = sequence.map(|b| Ok(b));

// media is now a proper `MediaStream` and can be used in the audio graph
let context = AudioContext::new();
let node = context.create_media_stream_source(media);
