unit8_t *data

[YJCCreateAHistory]

Hello, I have a problem now. When I use the following code, I will define a callback function for on_rgba_frame_data. Normally, this data will be a pointer reference. But the data in C++ is normal, and I get a null pointer. Is it the data structure I defined

exports.rtspRgbaCallback = cb => {
  const on_rgba_frame_data = koffi.proto('void on_rgba_frame_data(uint8_t *data, int width, int height)');

  const func = koffi.register((data, width, height) => {
    console.log('decodeData5=================rgba', data, width, height)
    const decodeData5 = new Uint8Array(data.buffer);
    cb({
      data: decodeData5,
      width: width,
      height: width === 1920 ? 1080 : 2160,
    });
  }, koffi.pointer(on_rgba_frame_data))
  try {
    rtsp_player_set_on_rgba_frame_data(rtspPlayer, func);
  } catch(err) {
    console.log(err, '----------------------------------------------------')
  }
};
