Dan*_*son 7 media android record cordova
我希望录制一些音频,然后才能播放它.能够自定义记录界面对我来说很重要.
在录制后的下面示例中,我得到-1的持续时间并且没有播放音频.
步骤1. 添加媒体插件
cordova plugin add org.apache.cordova.media
第2步.我的代码
注意src是文档中请求的"amr".
Android设备以自适应多速率格式录制音频.指定的文件应以.amr扩展名结尾.
但是,我的文件结构中不存在"myrecording.amr",因为我希望它会被创建.
使用Javascript
var data = {
rec: ""
};
$scope.record = function(){
console.log('record');
var src = "myrecording.amr";
data.rec = new Media(src,
function() {
console.log("recordAudio():Audio Success");
},
function(err) {
console.log("recordAudio():Audio Error: "+ err.code);
});
data.rec.startRecord();
}
$scope.stopRecording = function(){
console.log('stop');
data.rec.stopRecord();
}
$scope.playRecording = function(){
console.log('play');
data.rec.play();
}
$scope.logDuration = function(){
console.log(data.rec.getDuration());
}
HTML
<button ng-click="record()">Record</button>
<button ng-click="stopRecording()">Stop Record</button>
<button ng-click="playRecording()">Play Record</button>
<button ng-click="logDuration()">Log Duration</button>
从上面输出
点击播放时没有播放音频.
0 999846 log record
1 001845 log stop
2 002000 log recordAudio():Audio Success
3 004657 log play
4 008989 log -1
任何帮助将不胜感激.如果我能回答任何问题,请告诉我.
以下是我的工作步骤.
ionic start RecordTest blank
ionic platform add ios
cordova plugin add org.apache.cordova.media

ionic emulate ios以上应该有效.
