Question

我正在使用此库进行视频共享应用程序项目，我正在使用CameraDemo_layout，我将com.commonsware.cwac.camera.CameraView尺寸设置为320dip，高度和宽度。但是，录制的视频似乎具有电话屏幕尺寸的录制，这使得它看起来很错误。您能否指导我完成设置视频录制的过程，以遵循相机视图组布局的尺寸。谢谢。

我的活动：

public class RecordingActivity extends Activity implements

CameraHostProvider { private DemoCameraFragment current = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_recording);

    current=new DemoCameraFragment();

    getFragmentManager().beginTransaction()
    .replace(R.id.container, current).commit();


}

@Override
public CameraHost getCameraHost() {
    return(new SimpleCameraHost(this));
}

我的片段：

public class DemoCameraFragment extends CameraFragment {
android.hardware.Camera camera;

@Override
public View onCreateView(LayoutInflater inflater,
        ViewGroup container,
        Bundle savedInstanceState) {
    View content=inflater.inflate(R.layout.camera, container, false);
    CameraView cameraView=(CameraView)content.findViewById(R.id.camera);
    Log.d("daba", "the cameraview attrs: " + cameraView.getHeight() + " -- " + cameraView.getWidth());
    setCameraView(cameraView);


    //      SimpleCameraHost.Builder builder = new SimpleCameraHost.Builder(getActivity());
    //      builder.useFullBleedPreview(false);
    //      
    //      setHost(builder.build());

    final ImageButton record = (ImageButton) content.findViewById(R.id.record);
    final ImageButton next = (ImageButton) content.findViewById(R.id.next);
    next.setEnabled(false);
    record.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            if(record.getTag().toString().equals("Hi!")){
                try {
                    record();
                    record.setTag("By!");
                    record.setBackgroundColor(Color.DKGRAY);
                    next.setEnabled(true);
                } catch (Exception e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
            else{
                try {
                    stopRecording();
                    record.setTag("Hi!");
                    record.setBackgroundColor(Color.TRANSPARENT);
                } catch (Exception e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

            }

        }
    });


    next.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            if(isRecording())
                Toast.makeText(getActivity(), "Finish recording first", Toast.LENGTH_SHORT).show();
            else{
                Intent i = new Intent(getActivity(), VideoSetData.class);
                getActivity().startActivity(i);
            }
        }
    });

    if(isRecording()){


    }



    return(content);
}

}

我的Camera.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<com.commonsware.cwac.camera.CameraView
    android:id="@+id/camera"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
     />

<ImageButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:src="@drawable/cancel" />

<ImageButton
    android:id="@+id/next"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:src="@drawable/right" />

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:gravity="center"
    android:orientation="horizontal" >

    <ImageButton
        android:id="@+id/record"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/record"
        android:tag="Hi!" >
    </ImageButton>
</LinearLayout>

然而，录制的视频似乎有电话屏幕尺寸的录音，这看起来很错误

录音的分辨率应与CameraView的尺寸无关。录制的分辨率应来自the MediaRecorder使用setProfile()的配置。

setProfile()用于CameraHost中的configureRecorderProfile()。 SimpleCameraHost使用自己的算法来选择配置文件;您需要继承SimpleCameraHost并覆盖configureRecorderProfile()以使用不同的算法来选择配置文件。

相机预览和录制尺寸
