我正在使用getUserMedia()功能从麦克风捕获音频输入，在chrome中工作正常，但是在5秒钟之后，firefox声音就会消失。如果我再次发送麦克风请求(不重新加载页面)同样的事情发生。这是代码(我用
http://updates.html5rocks.com/2012/09/Live-Web-Audio-Input-Enabled作为指导)：
//getting the function depending on browser
navigator.getMedia = ( navigator.getUserMedia ||
navigator.webkitGetUserMedia ||
navigator.mozGetUserMedia ||
navigator.msGetUserMedia);
// success callback when requesting audio input stream
function gotAudioStream(stream) {
window.AudioContext = window.AudioContext || window.webkitAudioContext;
var audioContext = new AudioContext();
// Create an AudioNode from the stream.
var mediaStreamSource = audioContext.createMediaStreamSource( stream );
// Connect it to the destination to hear yourself (or any other node for processing!)
mediaStreamSource.connect( audioContext.destination );
}
function gotError(err) {
alert("An error occured! " + err);
}
//when button clicked,browser asks a permission to access microphone
jQuery("#sound_on").click(function()
{
navigator.getMedia({audio: true},gotAudioStream,gotError);
});@H_502_3@
有任何想法吗？
编辑/ UPDATE
谢谢你，csch，供参考。解决方案Karoun Kasraie工作！
context = new AudioContext();
navigator.getUserMedia({ audio: true },function(stream) {
// the important thing is to save a reference to the MediaStreamAudioSourceNode
// thus,*window*.source or any other object reference will do
window.source = context.createMediaStreamSource(stream);
source.connect(context.destination);
},alert);@H_502_3@
