Usage
use web_audio_api::context::{AudioContext, BaseAudioContext};
use web_audio_api::media::MediaElement;
use web_audio_api::node::AudioNode;
let context = AudioContext::default();
let mut media = MediaElement::new("samples/major-scale.ogg").unwrap();
let src = context.create_media_element_source(&mut media);
src.connect(&context.destination());
media.set_loop(true); // continuously loop
media.set_current_time(1.0); // seek to offset
media.play(); // start playing
loop {}
Examples
cargo run --release --example media_element
Implementations§

impl MediaElementAudioSourceNode
sourcepub fn new<C: BaseAudioContext>(
context: &C,
options: MediaElementAudioSourceOptions<'_>
) -> Self
pub fn new<C: BaseAudioContext>(

Create a new MediaElementAudioSourceNode
Panics
This method will panic when there already exists a source node for the given
MediaElement
. You can only set up a single source node per element!
