android循环请求数据,android – Camera2 ImageReader冻结重复捕获请求

我正在尝试使用camera2 API从相机捕获图像数据.我主要使用的是从

android Capture2RAW示例中获取的代码.在完全停止之前,只有少数图像通过(即调用on

ImageAvailable).我尝试使用不同大小的RAW_SENSOR和JPEG格式捕获相同的结果.我究竟做错了什么？

this.mImageReader = ImageReader.newInstance(width, height, ImageFormat.RAW_SENSOR, /*maxImages*/ 1);

Surface surface = this.mImageReader.getSurface();

final List surfaces = Arrays.asList(surface);

this.mCamera.createCaptureSession(surfaces, new CameraCaptureSession.StateCallback() {

// Callback methods here

}, null);

CaptureRequest.Builder captureRequestBuilder;

captureRequestBuilder = this.mCamera.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW);

captureRequestBuilder.addTarget(surface);

this.mCaptureRequest = captureRequestBuilder.build();

this.mCaptureSession.setRepeatingRequest(mCaptureRequest, null, null);
