android平台jpeg数据流转换成rgb直接显示的so库 使用方式： byte[] jpegRaw = V4L2Camera.decode(dataBuf, ret); rgb2Buffer(jpegRaw, WIDTH, HEIGHT, rgbBuffer); ByteBuffer jpegBuffer = ByteBuffer.wrap(rgbBuffer); bmp.copyPixelsFromBuffer(jpegBuffer); canvas.drawBitmap(bmp, null, rect, null); // draw camera bitmap native接口如下 package lzt.drv; public class V4L2Camera { static { System.loadLibrary("jpeg"); } public native static byte[] decode(byte[] jpegData, int length); public native static void release(); }
