AudioContext::create_media_element_source
§Usage
use web_audio_api::context::{AudioContext, BaseAudioContext};
use web_audio_api::MediaElement;
use web_audio_api::node::AudioNode;
let context = AudioContext::default();
let mut media = MediaElement::new("samples/major-scale.ogg").unwrap();
let mut 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§
Source§impl MediaElementAudioSourceNode
impl MediaElementAudioSourceNode
Sourcepub fn new<C: BaseAudioContext>(
context: &C,
options: MediaElementAudioSourceOptions<'_>,
) -> Self
pub fn new<C: BaseAudioContext>( context: &C, options: MediaElementAudioSourceOptions<'_>, ) -> Self
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!
