问题描述

我使用了链接(此处)中的信息并获得了以下代码,这有助于我使用网络摄像头录制视频.该代码允许我录制视频并使其可供下载.但是,我想将录制的视频自动保存到本地文件夹.我怎样才能做到这一点?

解决方案

您必须使用 recorder.getBlob() 方法来获取视频文件的实际 blob,然后将其发送到您的服务器然后将其保存到文件中:

javascript:

stopRecordingVideo.onclick = function() {this.disabled = true;recordVideo.disabled = false;如果(录音机)recorder.stopRecording(function(url) {video.src = url;视频播放();var RecordedBlob = recorder.getBlob();var formData = new FormData();formData.append("videofile", RecordedBlob);var xhr = new XMLHttpRequest();xhr.open("POST", "savevideofile.php");xhr.send(formData);document.getElementById('video-url-preview').innerHTML = '<a href="' + url + '>录制的视频网址</a>';});};

savevideofile.php:

I used the the information from the link (here) and got the following code, which helps me to record a video with my webcam. The code allows me to record a video and makes it available to download. However, I want to save the recorded video automatically to a local folder. How can I do that?

解决方案

You will have to use the recorder.getBlob() method to get the actual blob of the video file, then send it to your server which will then save it to a file :

javascript:

stopRecordingVideo.onclick = function() {
    this.disabled = true;
    recordVideo.disabled = false;

    if (recorder)
        recorder.stopRecording(function(url) {
            video.src = url;
            video.play();
            var recordedBlob = recorder.getBlob();
            var formData = new FormData();
            formData.append("videofile", recordedBlob);
            var xhr = new XMLHttpRequest();
            xhr.open("POST", "savevideofile.php");
            xhr.send(formData);
            document.getElementById('video-url-preview').innerHTML = '<a href="' + url + '>Recorded Video URL</a>';
        });
};

savevideofile.php:

<?php
if($_FILES['videofile']){
    $my_file = $_FILES['videofile'];
    $my_blob = file_get_contents($my_file['tmp_name']);
    file_put_contents('/path/to/your/file.webm', $my_blob);
    }
?>
