如何以纵向将 YUV_420_888 保存为 JPEG？

如何解决如何以纵向将 YUV_420_888 保存为 JPEG？

嗨，我是开发和编写相机应用程序的新手。我想以纵向将图像保存到我的设备。但是我的代码让它们保持横向！并且图像被拉伸。

我已阅读有关此主题的所有问题，但仍然找不到所需的答案。

要转换我使用：

 public static byte[] NV21toJPEG(byte[] nv21,int width,int height,int quality) {
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        YuvImage yuv = new YuvImage(nv21,ImageFormat.NV21,width,height,null);
        yuv.compresstoJpeg(new Rect(0,height),quality,out);
        return out.toByteArray();
    }

    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    public static byte[] YUV420toNV21(Image image) {
        Rect crop = image.getCropRect();
        int format = image.getFormat();
        int width = crop.width();
        int height = crop.height();
        Image.Plane[] planes = image.getPlanes();
        byte[] data = new byte[width * height * ImageFormat.getBitsPerPixel(format) / 8];
        byte[] rowData = new byte[planes[0].getRowStride()];

        int channelOffset = 0;
        int outputStride = 1;
        for (int i = 0; i < planes.length; i++) {
            switch (i) {
                case 0:
                    channelOffset = 0;
                    outputStride = 1;
                    break;
                case 1:
                    channelOffset = width * height + 1;
                    outputStride = 2;
                    break;
                case 2:
                    channelOffset = width * height;
                    outputStride = 2;
                    break;
            }
            ByteBuffer buffer = planes[i].getBuffer();
            int rowStride = planes[i].getRowStride();
            int pixelStride = planes[i].getPixelStride();

            int shift = (i == 0) ? 0 : 1;
            int w = width >> shift;
            int h = height >> shift;
            buffer.position(rowStride * (crop.top >> shift) + pixelStride * (crop.left >> shift));
            for (int row = 0; row < h; row++) {
                int length;
                if (pixelStride == 1 && outputStride == 1) {
                    length = w;
                    buffer.get(data,channelOffset,length);
                    channelOffset += length;
                } else {
                    length = (w - 1) * pixelStride + 1;
                    buffer.get(rowData,length);
                    for (int col = 0; col < w; coL++) {
                        data[channelOffset] = rowData[col * pixelStride];
                        channelOffset += outputStride;
                    }
                }
                if (row < h - 1) {
                    buffer.position(buffer.position() + rowStride - length);
                }
            }
        }
        return data;
    }

请帮帮我！
