在做人脸识别的时候,发现内存一直增加,但是该释放的资源已经释放,经过跟厂家一起排查,是在compressToJpeg转换的时候导致的
原代码::YuvImage yuvImage = new YuvImage(data, ImageFormat.NV21, size.width, size.height, null);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
yuvImage.compressToJpeg(new Rect(0, 0, size.width, size.height), 100, baos);
byte[] byteArray = baos.toByteArray();
后改成直接转成bitmap。
Bitmap yuv2Bitmap = BitmapUtils.yuv2Bitmap(data, size.width, size.height);
public static Bitmap yuv2Bitmap(byte[] data, int width, int height) {
int frameSize = width * height;
int[] rgba = new int[frameSize];
for (int i = 0; i < height; i++) {
for (int j = 0; j < width; j++) {
int y = (0xff & ((int) data[i * width + j]));
int u = (0xff & ((int) data[frameSize + (i >> 1) * width + (j & ~1) + 0]));
int v = (0xff & ((int) data[frameSize + (i >> 1) * width + (j & ~1) + 1]));
y = y < 16 ? 16 : y;
int r = Math.round(1.164f * (y - 16) + 1.596f * (v - 128));
int g = Math.round(1.164f * (y - 16) - 0.813f * (v - 128) - 0.391f * (u - 128));
int b = Math.round(1.164f * (y - 16) + 2.018f * (u - 128));
r = r < 0 ? 0 : (r > 255 ? 255 : r);
g = g < 0 ? 0 : (g > 255 ? 255 : g);
b = b < 0 ? 0 : (b > 255 ? 255 : b);
rgba[i * width + j] = 0xff000000 + (b << 16) + (g << 8) + r;
}
}
Bitmap bmp = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
bmp.setPixels(rgba, 0, width, 0, 0, width, height);
return bmp;
}
观察了几天,并不会出现
