Android YUV Image format

Question

In our application, we need to transfer video, we are using Camera class to capture the buffer and send to destination, I have set format is YV12 as a Camera parameter to receive the buffer, for the 500X300 buffer, we receive buffer of 230400 bytes, i want to know , is this expected buffer size ? I believe the size would be Y Plane = width * height = 500X300 = 150000 U Plane = width/2 * height/2 = = 37500 V Plane = width/2 * height/2 = = 37500 ======== 225000 ======== Can anyone explain me, if i need to get stride values of each component, how can i get that Is there any way to get it ?

Answer 1

I can show you how you can get int rgb[] from this: public int[] decodeYUV420SP(byte[] yuv420sp, int width, int height) { final int frameSize = width * height; int rgb[] = new int[width * height]; for (int j = 0, yp = 0; j < height; j++) { int uvp = frameSize + (j >> 1) * width, u = 0, v = 0; for (int i = 0; i < width; i++, yp++) { int y = (0xff & ((int) yuv420sp[yp])) - 16; if (y < 0) y = 0; if ((i & 1) == 0) { v = (0xff & yuv420sp[uvp++]) - 128; u = (0xff & yuv420sp[uvp++]) - 128; } int y1192 = 1192 * y; int r = (y1192 + 1634 * v); int g = (y1192 - 833 * v - 400 * u); int b = (y1192 + 2066 * u); if (r < 0) r = 0; else if (r > 262143) r = 262143; if (g < 0) g = 0; else if (g > 262143) g = 262143; if (b < 0) b = 0; else if (b > 262143) b = 262143; rgb[yp] = 0xff000000 | ((r << 6) & 0xff0000) | ((g >> 2) & 0xff00) | ((b >> 10) & 0xff); } } return rgb; }
