推荐答案

使用MediaRecorder用于这一目的。尽管这将需要更多的工作，但会给你更多的控制。按照此链接 HTTP：//android-er.blogspot。 TW / 2011/04 /启动录像-using.html 。既然你不reuire任何按钮点击记录，开始在镜头前保持延迟。像这样做

Use MediaRecorder for this purpose. Though it will require more work but will give you much more control. Follow this link http://android-er.blogspot.tw/2011/04/start-video-recording-using.html. Since you don't reuire any button click for recording, keep a delay before starting the camera. Do it like this

myButton.setPressed(true); //you won't click the button
myButton.invalidate();
myButton.postDelayed(new Runnable() {  
    public void run() {      
         myButton.setPressed(false); 
         myButton.invalidate();
         releaseCamera();   //release camera from preview before MediaRecorder starts
        if(!prepareMediaRecorder()){
            Toast.makeText(AndroidVideoCapture.this,"could not prepare MediaRecorder",Toast.LENGTH_LONG).show();
            finish();
        }
        mediaRecorder.start();
    }
},5000); //causes delay of 5 seconds befor recording starts
