我可以在浏览器中使用getUserMedia()
录制视频。但是,我没有找到一种方便的方法从浏览器向服务器提交(录制)或流媒体(实时)视频。
我发现只有将视频渲染到画布然后提交或流式传输渲染图像,例如通过数据uri。 (这没有效果。)
有更好的方法吗? (例如,直接流式传输二进制数据或将它们存储在文件中,然后发送此文件。)
更新:我发现了类似的旧问题:Stream getUserMedia to an Icecast server?

MediaStreamRecorder是用于记录getUserMedia()流的WebRTC API。它允许Web应用程序通过实时音频/视频会话创建文件。
<video autoplay></video>
<script language="javascript" type="text/javascript">
function onVideoFail(e) {
console.log('webcam fail!', e);
};
function hasGetUserMedia() {
// Note: Opera is unprefixed.
return !!(navigator.getUserMedia || navigator.webkitGetUserMedia ||
navigator.mozGetUserMedia || navigator.msGetUserMedia);
}
if (hasGetUserMedia()) {
// Good to go!
} else {
alert('getUserMedia() is not supported in your browser');
}
window.URL = window.URL || window.webkitURL;
navigator.getUserMedia = navigator.getUserMedia ||
navigator.webkitGetUserMedia ||
navigator.mozGetUserMedia ||
navigator.msGetUserMedia;
var video = document.querySelector('video');
var streamRecorder;
var webcamstream;
if (navigator.getUserMedia) {
navigator.getUserMedia({audio: true, video: true}, function(stream) {
video.src = window.URL.createObjectURL(stream);
webcamstream = stream;
// streamrecorder = webcamstream.record();
}, onVideoFail);
} else {
alert ('failed');
}
function startRecording() {
streamRecorder = webcamstream.record();
setTimeout(stopRecording, 10000);
}
function stopRecording() {
streamRecorder.getRecordedData(postVideoToServer);
}
function postVideoToServer(videoblob) {
var data = {};
data.video = videoblob;
data.metadata = 'test metadata';
data.action = "upload_video";
jQuery.post("http://www.foundthru.co.uk/uploadvideo.php", data, onUploadSuccess);
}
function onUploadSuccess() {
alert ('video uploaded');
}
</script>
<div id="webcamcontrols">
<button class="recordbutton" onclick="startRecording();">RECORD</button>

您可以将录制的文件发送到服务器。

目前它不是任何浏览器的一部分,但至少会在Chrome中出现。查看http://code.google.com/p/chromium/issues/detail?id=113676
