HarmonyOS 使用ohcamera/camera.h在Native层获取摄像头采集的视频YUV数据？

Question

本地摄像头采集的视频，除了使用下面的ImageReceiver方式获取到，在Native层，使用 \#include "ohcamera/camera.h"中是否也可以同样获取到本地摄像头采集的视频数据？需要获取到摄像头采集的YUV数据，然后编码发送，请给出使用ohcamera/camera.h获取视频数据的方案，最好有代码示例。

private mReceiver: image.ImageReceiver;
this.mReceiver = image.createImageReceiver(this.cameraSize, 2000, 8);
this.mReceiver.on('imageArrival', () => {
  if (this.mReceiver) {
    this.mReceiver.readNextImage((err, image) => {
      if (err || image === undefined) {
        return;
      }
      image.getComponent(4, (errMsg, img) => {
        if (errMsg || img === undefined) {
          return;
        }
        let buffer = new ArrayBuffer(2048);
        if (img.byteBuffer) {
          buffer = img.byteBuffer;
        }
        else {
          Logger.error(this.tag, 'img.byteBuffer is undefined');
        }
        this.savePicture(buffer, image);
      })
    })
  }
})

Answer 1

Native侧也提供了imageReceiver。
