无法播放使用Android版Chrome一个blob的URL视频 [英] Can't play a blob-url video using Chrome for Android
问题描述
我现在面临一个不寻常的问题，而试图记录和Chrome中播放的视频为Android。 （同code正常工作在Chrome桌面）。
I'm facing an unusual issue while trying to record and play a video in Chrome for Android. (Same code works fine on Chrome for Desktop).
首先，一些信息：
- 是Android 4.4.2
- Android版Chrome 40.0.2214.89
- 它适用于Chrome浏览器的桌面40.0.2214.94米
- 在本地文件存储BLOB后，它的正确的媒体播放器应用程序内再现。
- 必需RecordRTC.js
我的目标是，记录来自平板电脑的摄像头的视频，比播放录制的视频。
这里有一个例子code：
My goal is that to record a video from tablet's camera and than play the recorded video. Here's an example code:
<!DOCTYPE html>
<html>
<head>
<title>Camera Test</title>
<script type="text/javascript" src="//cdn.WebRTC-Experiment.com/RecordRTC.js"></script>
</head>
<body>
<script>
var cameraStream;
var cameraEl;
var cameraRecorder;
var cameraBlobURL;
window.URL = window.URL || window.webkitURL;
navigator.getUserMedia = ( navigator.getUserMedia ||
navigator.webkitGetUserMedia ||
navigator.mozGetUserMedia ||
navigator.msGetUserMedia);
function askForCamera(){
navigator.getUserMedia(
{
video : true
},
function(stream) {
cameraStream = stream;
cameraEl = document.getElementById("vidCamera");
cameraEl.src = window.URL.createObjectURL(stream);
},
function(){
alert('fail camera');
}
);
}
function playCamera(){
cameraEl.play();
}
function startRec(){
cameraRecorder = RecordRTC(
cameraStream,
{
type: 'video',
disableLogs : true
}
);
cameraRecorder.startRecording();
}
function stopRec(){
cameraRecorder.stopRecording(function(blobURL){
cameraBlobURL = blobURL;
console.log(cameraBlobURL);
alert(cameraRecorder.getBlob().type + ' ' +cameraRecorder.getBlob().size);
});
}
function setBlob(){
cameraEl.src = cameraBlobURL;
}
</script>
<p>Buttons:</p>
<button type="button" onclick="askForCamera()">Ask for camera</button>
<button type="button" onclick="playCamera()">Play camera</button>
<button type="button" onclick="startRec()">Start Rec</button>
<button type="button" onclick="stopRec()">Stop Rec</button>
<button type="button" onclick="setBlob()">Set blob to camera</button>
<button type="button" onclick="playCamera()">Play camera</button>
<br/>
<p>Camera:</p>
<video id="vidCamera" width="200" height="200">
</video>
</body>
</html>
我应该如何进行，以确保它适用于Android版Chrome？
希望有人能帮助我。
感谢所有！
