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<Surface> 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);

@Override
onImageAvailable(ImageReader reader) {
    Image image = reader.acquireLatestImage();
    // Process the image
    image.close();
}
