5秒后录制停止在mozilla但在chrome

Question

HTML5麦克风捕获在Firefox中停止5秒后停止。它在Chrome中运行良好。我从Github那里获取了这段代码。

var audio_context;
var recorder;
var localStream; // line added by me

function startUserMedia(stream) {
    localStream = stream; // line added by me
    var input = audio_context.createMediaStreamSource(stream);

Answer 1

var audio_context;
var recorder;

function startUserMedia(stream) {
var input = audio_context.createMediaStreamSource(stream);

将上述行更改为：

var audio_context;
var recorder;
var localStream; // line added by me

function startUserMedia(stream)  {
localStream = stream; // line added by me
var input = audio_context.createMediaStreamSource(stream);
