hi3615dv500 sensor：os04a10 测量从 VPSS（视频处理子系统）获取一帧 YUV 数据的耗时

我把咱们示例的smple_vio裁剪了一下，变成了单摄像头 VI → VPSS → VENC/VO 链路。可以正常运行，可以查看到相关信息和摄像头画面。
我后边想要测量从 VPSS（视频处理子系统）获取一帧 YUV 数据的耗时：
使用了一个性能测试线程函数
将其放在sample_vio_start_route中
static td_s32 sample_vio_start_route(sample_vi_cfg vi_cfg, sample_vpss_cfg vpss_cfg, td_s32 route_num)
{
td_s32 i, j, ret;
ot_vpss_grp vpss_grp[SAMPLE_VIO_MAX_ROUTE_NUM] = {0, 1, 2, 3};

sample_comm_vi_get_size_by_sns_type(SENSOR0_TYPE, &g_vb_param.vb_size);
if (sample_vio_sys_init() != TD_SUCCESS) {
    return TD_FAILURE;
}

// 启动VI
for (i = 0; i < route_num; i++) {
    ret = sample_comm_vi_start_vi(&vi_cfg[i]);
    if (ret != TD_SUCCESS) {
        goto start_vi_failed;
    }
}

// 绑定VI和VPSS并使能通道
for (i = 0; i < route_num; i++) {
    sample_comm_vi_bind_vpss(i, 0, vpss_grp[i], 0);
    if (ss_mpi_vi_enable_chn(i, 0) != TD_SUCCESS) {
        goto start_vi_failed;
    }
}

// 启动VPSS
for (i = 0; i < route_num; i++) {
    ret = sample_vio_start_vpss(vpss_grp[i], vpss_cfg);
    if (ret != TD_SUCCESS) {
        goto start_vpss_failed;
    }
    if (ss_mpi_vpss_enable_chn(vpss_grp[i], 0) != TD_SUCCESS) {
        goto start_vpss_failed;
    }
}

// 启动VENC和VO（链路完全建立）
ret = sample_vio_start_venc_and_vo(vpss_grp, SAMPLE_VIO_MAX_ROUTE_NUM, route_num);
if (ret != TD_SUCCESS) {
    goto start_venc_and_vo_failed;
}

// 链路启动成功后，启动计时线程
pthread_t tid;
if (pthread_create(&tid, NULL, perf_thread, (void*)&vpss_grp[0]) != 0) {
    printf("创建计时线程失败!\n");
} else {
    pthread_detach(tid); // 分离线程，独立运行
}

return TD_SUCCESS;

// 错误处理部分（保持不变）

start_venc_and_vo_failed:
start_vpss_failed:
for (j = i - 1; j >= 0; j—) {
sample_vio_stop_vpss(vpss_grp[j]);
}
for (i = 0; i < route_num; i++) {
sample_comm_vi_un_bind_vpss(i, 0, vpss_grp[i], 0);
}
start_vi_failed:
for (j = i - 1; j >= 0; j—) {
sample_comm_vi_stop_vi(&vi_cfg[j]);
}
sample_comm_sys_exit();
return TD_FAILURE;
}
这是线程函数的代码:
static void perf_thread(void arg)
{
ot_vpss_grp grp = (ot_vpss_grp)arg;
ot_vpss_chn chn = 0;
int cnt = 0;
double total = 0, min = 1e9, max = 0;

printf("\n=== VI->VPSS->VENC/VO 链路性能计时开始 ===\n");
printf("从 VPSS GRP%d CH%d 拿 YUV 帧（链路出口）\n", grp, chn);

while (cnt < 100 && !g_sig_flag) {
    ot_video_frame_info frame= {0};
    double t0 = now_ms();
    td_s32 ret = ss_mpi_vpss_get_chn_frame(grp, chn, &frame, 100);

    if (ret != TD_SUCCESS) {
        // 修正：使用OT_ERR_TIMEOUT替代TD_TIMEOUT
        if (ret == OT_ERR_TIMEOUT) {
            printf("获取帧超时（%d次）\n", cnt);
        } else {
            printf("获取帧失败（错误码:0x%x）\n", ret);
        }
        usleep(10000);
        continue;
    }


    double t1 = now_ms();
    double delta = t1 - t0;
    total += delta;
    min = (delta < min) ? delta : min;
    max = (delta > max) ? delta : max;
    cnt++;

    ss_mpi_vpss_release_chn_frame(grp, chn, &frame);

    if (cnt % 10 == 0) {
        printf("已获取 %03d 帧，当前帧耗时: %.2f ms\n", cnt, delta);
    }
}


if (cnt > 0) {
    printf("=== 计时结束 ===\n");
    printf("总帧数: %d\n", cnt);
    printf("平均耗时: %.2f ms\n", total / cnt);
    printf("最小耗时: %.2f ms\n", min);
    printf("最大耗时: %.2f ms\n", max);
} else {
    printf("=== 计时结束：未获取到有效帧 ===\n");
}
return NULL;

}
```
