MediaStreamRecorder.js / Demo

A cross-browser implementation to record audio/video streams:

1. MediaStreamRecorder can record both audio and video in single WebM file on Firefox.
2. MediaStreamRecorder can record audio as WAV and video as either WebM or animated gif on Chrome.

Record audio+video on Firefox in single WebM

<script src="//www.webrtc-experiment.com/MediaStreamRecorder.js"> </script>

var mediaConstraints = {
    audio: true, // don't forget audio!
    video: true  // don't forget video!
};

navigator.mozGetUserMedia(mediaConstraints, onMediaSuccess, onMediaError);

function onMediaSuccess(stream) {
    var mediaRecorder = new MediaStreamRecorder(stream);
    mediaRecorder.mimeType = 'video/webm';
    mediaRecorder.ondataavailable = function (blob) {
        // POST/PUT "Blob" using FormData/XHR2
        window.open(URL.createObjectURL(blob));
    };
    mediaRecorder.start(3000);
}

function onMediaError(e) {
    console.error('media error', e);
}

Record only audio on chrome

<script src="//www.webrtc-experiment.com/MediaStreamRecorder.js"> </script>

var mediaConstraints = {
    audio: true
};

navigator.mozGetUserMedia(mediaConstraints, onMediaSuccess, onMediaError);

function onMediaSuccess(stream) {
    var mediaRecorder = new MediaStreamRecorder(stream);
    mediaRecorder.mimeType = 'audio/ogg';
    mediaRecorder.ondataavailable = function (blob) {
        // POST/PUT "Blob" using FormData/XHR2
        window.open(URL.createObjectURL(blob));
    };
    mediaRecorder.start(3000);
}

function onMediaError(e) {
    console.error('media error', e);
}

Record video/gif on chrome

<script src="//www.webrtc-experiment.com/MediaStreamRecorder.js"> </script>

var mediaConstraints = {
    video: true
};

navigator.mozGetUserMedia(mediaConstraints, onMediaSuccess, onMediaError);

function onMediaSuccess(stream) {
    var mediaRecorder = new MediaStreamRecorder(stream);
    mediaRecorder.mimeType = 'video/webm';
	
    // for gif recording
    // mediaRecorder.mimeType = 'image/gif';
	
    mediaRecorder.videoWidth = 320;
    mediaRecorder.videoHeight = 240;
	
    mediaRecorder.ondataavailable = function (blob) {
        // POST/PUT "Blob" using FormData/XHR2
        window.open(URL.createObjectURL(blob));
    };
    mediaRecorder.start(3000);
}

function onMediaError(e) {

How to upload record files using PHP?

PHP code:

<?php
foreach(array('video', 'audio') as $type) {
    if (isset($_FILES["${type}-blob"])) {
        
		$fileName = $_POST["${type}-filename"];
        $uploadDirectory = "uploads/$fileName";
        
        if (!move_uploaded_file($_FILES["${type}-blob"]["tmp_name"], $uploadDirectory)) {
            echo("problem moving uploaded file");
        }
		
		echo($uploadDirectory);
    }
}
?>

JavaScript Code:

var fileType = 'video'; // or "audio"
var fileName = 'ABCDEF.webm';  // or "wav" or "ogg"

var formData = new FormData();
formData.append(fileType + '-filename', fileName);
formData.append(fileType + '-blob', blob);

xhr('save.php', formData, function (fileURL) {
    window.open(fileURL);
});

function xhr(url, data, callback) {
    var request = new XMLHttpRequest();
    request.onreadystatechange = function () {
        if (request.readyState == 4 && request.status == 200) {
            callback(location.href + request.responseText);
        }
    };
    request.open('POST', url);
    request.send(data);
}
