HTML 怎么实时获取摄像头视频流推送到流媒体服务器

下列代码可以调用摄像头，可是怎么把视频流推送到rtmp流媒体服务器？

var video = document.getElementById("video");
var errocb = function() {
console.log('sth wrong!');
}
if(navigator.getUserMedia) { // 标准的API
navigator.getUserMedia({
"video": true
}, function(stream) {
video.src = stream;
video.play();
}, errocb);
}
