试试这个方法(-_-)
IFrameCallback iFrameCallback = new IFrameCallback() {
@Override
public void onFrame(ByteBuffer frame) {
//get nv12 data
byte[] b = new byte[frame.remaining()];
frame.get(b);
//nv12 data to nv21
NV12ToNV21(b, 1280, 720);
//send NV21 data
BVPU.InputVideoData(nv21, nv21.length,
System.currentTimeMillis() * 1000, 1280, 720);
}
};
byte[] nv21;
private void NV12ToNV21(byte[] data, int width, int height) {
nv21 = new byte[data.length];
int framesize = width * height;
int i = 0, j = 0;
System.arraycopy(data, 0, nv21, 0, framesize);
for (i = 0; i < framesize; i++) {
nv21[i] = data[i];
}
for (j = 0; j < framesize / 2; j += 2) {
nv21[framesize + j - 1] = data[j + framesize];
}
for (j = 0; j < framesize / 2; j += 2) {
nv21[framesize + j] = data[j + framesize - 1];
}
}
