Remarks
YuvImage contains YUV data and provides a method that compresses a region of the YUV data to a Jpeg. The YUV data should be provided as a single byte array irrespective of the number of image planes in it. Currently only ImageFormat.NV21 and ImageFormat.YUY2 are supported.
To compress a rectangle region in the YUV data, users have to specify the region by left, top, width and height.
