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 ?
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;
}
