问题描述

是否有可能记录在视频服务，即不设置一套previewDisplay？
我想它在HTC Desire的，但它是引发此信息在日志中，

Is it possible to record video in a service, that is without setting the setPreviewDisplay? I tried it on a HTC Desire, however it is throwing this info in the log,

MediaRecorder prepare失败：-1

MediaRecorder Prepare Failed: -1

CameraInput无面可用于显示

有一些额外的属性进行设置？

推荐答案

我发现这个片段的某个地方。不知道这是否适用于媒体的记录，但它的工作相当不错关于HTC的Andr​​oid英雄2.1 UPDATE1（和仿真）camera.takePicture。

I found this snippet somewhere. Not sure if it works for media recorder, but it was working reasonably well for camera.takePicture on HTC hero android 2.1-update1 (and simulator).

if (camera == null) {
    Log.i(TAG, "Opening camera");
    camera = Camera.open();
}

SurfaceView view = new SurfaceView(new DummyContext()); //You'll have to create your own class extending Context
camera.setPreviewDisplay(view.getHolder());
camera.startPreview();

//wait
Log.i(TAG, "Wait for cam");
    try {
    Thread.sleep(2000);
} catch (InterruptedException e) {
    Log.e(TAG, "Woken violently");
    e.printStackTrace();
}

//take pic
Log.i(TAG, "Take pic");
camera.takePicture(shutterCallback, rawCallback, jpegCallback);
