Question

我尝试了以下代码。我想在后台录制视频并存储在SD卡中。我不想手动开始录制和停止。是否可以在PhoneGap中录制带或不带API的视频。我想在后台录制视频

<title>Capture Video</title>
<script type="text/javascript" charset="utf-8" src="js/cordova.js"></script>

    // A button will call this function
    function captureVideo() {
        // Launch device video recording application, 
        // allowing user to capture up to 3 video clips
        alert("captureVideo");
        var options = {
            limit : 2,
            duration : 10
        };
        navigator.device.capture.captureVideo(captureSuccess, captureError,
                options);
    }
    // Called when capture operation is finished
    function captureSuccess(
    mediaFiles) {
        alert("captureSuccess   ");
        var i, len;
        alert(mediaFiles.length);
        for (i = 0, len = mediaFiles.length; i < len; i += 1) {
            uploadFile(mediaFiles[i]);
        }
    }
    // Called if something bad happens.
    function captureError(error) {
        var msg = 'An error occurred during capture: ' + error.code;
        navigator.notification.alert(msg, null, 'Uh oh!');

    }
    // Upload files to server
    function uploadFile(mediaFile) {
        alert("uploadFile");
        var ft = new FileTransfer(), path = mediaFile.fullPath, name = mediaFile.name;
        alert("path:" + path);
        alert("name:" + name);
        ft.upload(path, "http://my.domain.com/upload.php", function(result) {
            console.log('Upload success: ' + result.responseCode);
            console.log(result.bytesSent + ' bytes sent');
        }, function(error) {
            console.log('Error uploading file ' + path + ': ' + error.code);

Answer 1

document.addEventListener("deviceready", start_here, false);

function start_here(){captureVideo();}
在启动应用程序和自动录制视频时调用函数并在再次发送后开始录制...

    function uploadFile(mediaFile) {
           alert("uploadFile");
            var ft = new FileTransfer(), path = mediaFile.fullPath, name = mediaFile.name;
            alert("path:" + path);
            alert("name:" + name);
            ft.upload(path, "http://my.domain.com/upload.php", function(result) {
                console.log('Upload success: ' + result.responseCode);
                console.log(result.bytesSent + ' bytes sent');
            }, function(error) {
                console.log('Error uploading file ' + path + ': ' + error.code);
            }, {
                fileName : name
            });
start_here;   /*just call the instance. here is the change*/       
}

现在，您可以使用最小化的应用程序录制视频，甚至可以通过cordova\phonegap\ionic plugin

来关闭屏幕

它是一个分支，但主要的回购不能录制视频＆＃34;在后台＆＃34; （尽管名称）。

启动时，它会根据SD和内部磁盘上的可用空间大小自动选择存储视频的位置。

cordova plugin add cordova-backgroundvideo

var fileName = new Date().getTime() + '';
cordova.plugins.backgroundvideo.start(fileName, 'back', true, null, null);

cordova.plugins.backgroundvideo.stop(function (filePath) {
    alert(filePath);
  }, function (error) {
    alert('Error ' + JSON.stringify(error));
  }
);

Android中的视频捕获在phoneGap的背景中，最小化的录制屏幕
