Question

我创建了一个相机应用程序：

mCamera =Camera.open()
mCamera.setDisplayOrientation(90);

我捕捉图像和视频确定。但结果不是旋转90。摄像机的运行结果如何与相机视图相同？或者设置结果输出相同的setDisplayOrientation？

在捕获后使用Android中的EXIF界面旋转图像

    ExifInterface exif;
    try {
        exif = new ExifInterface(filePath);

        int orientation = exif.getAttributeInt(
                ExifInterface.TAG_ORIENTATION, 0);
        Log.d("EXIF", "Exif: " + orientation);
        Matrix matrix = new Matrix();
        if (orientation == 6) {
            matrix.postRotate(90);
            Log.d("EXIF", "Exif: " + orientation);
        } else if (orientation == 3) {
            matrix.postRotate(180);
            Log.d("EXIF", "Exif: " + orientation);
        } else if (orientation == 8) {
            matrix.postRotate(270);
            Log.d("EXIF", "Exif: " + orientation);
        }
        bmp = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(),
                bmp.getHeight(), matrix, true);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

setDisplayOrientation（90）时如何旋转结果图像（或视频）？
