HTML5 solution to upload a webcam/camera video stream to server
提问by Vikas
Using getUserMediaI can capture video stream from client's webcam/camera. And using videotag I can show it on client's browser. Code:
使用getUserMedia我可以从客户端的网络摄像头/相机捕获视频流。并使用video标签我可以在客户端的浏览器上显示它。代码：
<video autoplay></video>
<script type="text/javascript">
window.URL = window.URL || window.webkitURL;
navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia;
var video = $('video')[0];
var failed = function(e) {
console.log('Denied!', e);
};
if( navigator.getUserMedia ) {
navigator.getUserMedia( {video: true, audio: true}, function( stream ) {
video.src = window.URL.createObjectURL(stream);
}, failed
)
} else {
console.log( 'Not supported!' );
}
</script>
Now is it possible to send this video stream, either as a realtime feed or after user has done recording and decided to upload, to a server?
现在是否可以将此视频流作为实时馈送或在用户完成录制并决定上传后发送到服务器？

MediaStreamRecorder is a WebRTC API for recording getUserMedia() streams . It allows web apps to create a file from a live audio/video session.

setTimeout(stopRecording, 10000);

function stopRecording() {

function postVideoToServer(videoblob) {
var data = {};
data.video = videoblob;
data.metadata = 'test metadata';
data.action = "upload_video";
jQuery.post("http://www.kongraju.in/uploadvideo.php", data, onUploadSuccess);

function onUploadSuccess() {

It shows a use of Webrtc:
它显示了Webrtc的使用：
These APIs should enable building applications that can be run inside a browser, requiring no extra downloads or plugins, that allow communication between parties using audio, video and supplementary real-time communication, without having to use intervening servers (unless needed for firewall traversal, or for providing intermediary services).
这些 API 应该能够构建可以在浏览器内运行的应用程序，不需要额外的下载或插件，允许使用音频、视频和补充实时通信的各方进行通信，而不必使用中间服务器（除非需要穿越防火墙，或提供中介服务）。
