标题: demo 推理耗时长

参考上面的 demo 把USB 摄像头改成本地 h264码流。平均每帧耗时70ms 请问这个效率正常吗?

cost_time=3 ms
rga ok
detect_time = 6954ms

detect_time 推理计算的代码没有改动

      start_time = get_time();
      ret = rknn_api.inference(rgbImg.data,
                                       img_width *
                                       img_height *
                                       img_channels,
                                       out_data->out);
      if (ret < 0) {
            printf("inference fail! ret=%d\n", ret);
            goto Error;
      }

      end_time = get_time();

      detect_count++;
      detect_time += (end_time - start_time);

      if (detect_count > 100) {
            printf("detect_time = %dms\n", detect_time);
            detect_count = 0;
            detect_time = 0;
      }
