Question

下面的代码在许多设备上成功运行（即使在三星Galaxy Note3上），但它不能在三星Galaxy Note 4上运行，我开始预览然后如果用户按下方法运行下面的保存按钮。如果我删除setVideSize line eveything在Note 4中正常工作，但如果我添加它，屏幕堆栈。

感谢您的关注。

try {
        mCamera.setDisplayOrientation(90);
    } catch (Exception e1) {
        e1.printStackTrace();
    }

    List<Camera.Size> sizes = mCamera.getParameters().getSupportedVideoSizes();
    mCamera.unlock();
    if(mediaRecorder == null)
        mediaRecorder = new MediaRecorder();
    mediaRecorder.setPreviewDisplay(this.getHolder().getSurface());
    if (mCameraId != CameraInfo.CAMERA_FACING_FRONT) {
        mediaRecorder.setOrientationHint(90);

    }

    mediaRecorder.setCamera(mCamera);

    mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
    Log.e("W = ",""+sizes.get(0).width);
    Log.e("H = ",""+sizes.get(0).height);
    mediaRecorder.setVideoSize(sizes.get(0).width, sizes.get(0).height);
    mediaRecorder.setOutputFile(fileName);

    mediaRecorder.setVideoFrameRate(20);
    mediaRecorder.setVideoEncodingBitRate(2000000);

    mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);

    try {
        mediaRecorder.prepare();
        mediaRecorder.start();
    } catch (Exception e) {
        e.printStackTrace();
        releaseMediaRecorder();
        relaseCamera();
        return false;

    }
    return true;

解

try {
        mCamera.setDisplayOrientation(90);
    } catch (Exception e1) {
        e1.printStackTrace();
    }


    mCamera.unlock();
    mediaRecorder = new MediaRecorder();    
    mediaRecorder.setCamera(mCamera);
    mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
    mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);

    mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
    mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
    mediaRecorder.setOutputFile(fileName);
    mediaRecorder.setVideoSize(1280,720);
    mediaRecorder.setVideoFrameRate(20);
    mediaRecorder.setVideoEncodingBitRate(2000000);
    if(mediaRecorder == null)
        mediaRecorder = new MediaRecorder();
    mediaRecorder.setPreviewDisplay(this.getHolder().getSurface());
    if (mCameraId != CameraInfo.CAMERA_FACING_FRONT) {
        mediaRecorder.setOrientationHint(90);

    }


    try {

        mediaRecorder.prepare();
        mediaRecorder.start();
    } catch (Exception e) {
        e.printStackTrace();
        releaseMediaRecorder();
        relaseCamera();
        return false;

    }
    return true;
