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;
}
