It's unclear how to use srt

It looks like there should be an udp provider that srt-live-transmit hooks up to. but then how to enable the udp source 🤔

I have downloaded all the resources + toolchains+sdk on the board. How can i compile them on dv300 board?

https://github.com/openhisilicon/HIVIEW/tree/master/mod/mpp/3516a/lib/hisisdk/libsns_imx335_2l.so
When running this driver on 3516dv300, an error occurred. I had set the corresponding parameters in sample_comm_vi.c of 3516av300, using 10 bits, 0 and 2 lane, as well as LANE.DIVIDE-MODE_1.
The following is the error message:
[Func]:IMX335_exit [Line]:208 [Info]:i2c exit failed!
linear mode
[Func]:HI_ISP_Init [Line]:498 [Info]:ISP[0] DngInfo not initialized in Cmos.c!

Good morning,

Would it be possible to have the code added to the repo to be able to compile the libraries/binaries?

svp 模块中 VpssCapture 成员函数 int VpssCapture::YUV2Mat(VIDEO_FRAME_S* pVBuf, cv::Mat& img) ，有调用 HI_MPI_SYS_MmzAlloc_Cached。 如果连续使用空 img 做参数，导致持续分配，最终 mmz 耗尽失败 orz...

改进建议：在 HI_MPI_SYS_MmzAlloc_Cached分配前若非空则调用 HI_MPI_SYS_MmzFree 释放。

3516DV300用020sdk移植遇到的错误

您好，我目前使用的板载平台为您公司产品Hi3516DV300，目前出现海康IPC对接HIVIEW后，输出VO的第二屏一直是IPC摄像头采集数据的一个回放情况【几分钟前到当前时间】，而且速度非常快，请问这个需要如何解决？

onvif module depends on libgsoap.a and the current version was pushed May 24, 2020 Since then there were a couple of major vulnerability disclosures about the library, including TALOS-2021-1245

Also the code snippet from the report :

soap_decode(char *buf, size_t len, const char *val, const char *sep)
{
  const char *s;
  char *t = buf;
  size_t i = len;
  if (!buf || !val || !sep || len == 0)
    return val;
  for (s = val; *s; s++)
    if (*s != ' ' && *s != '\t' && !strchr(sep, *s))
      break;
  if (len > 0)
  {
    if (*s == '"')
    {
      s++;
      while (*s && *s != '"' && i-- > 1)
        *t++ = *s++;
    }
    else
    {
      while (*s && !strchr(sep, *s) && i-- > 1)
      {
        if (*s == '%' && s[1] && s[2])
        {
          *t++ = ((s[1] >= 'A' ? (s[1] & 0x7) + 9 : s[1] - '0') << 4)
                + (s[2] >= 'A' ? (s[2] & 0x7) + 9 : s[2] - '0');
          s += 3;
        }
        else
          *t++ = *s++;
      }
    }
    buf[len - 1] = '\0'; /* appease static checkers that get confused */
  }
  *t = '\0';
  while (*s && !strchr(sep, *s))
    s++;
  return s;
}

looks very similar ( after translation back into C ) to what you provide in this repo:

byte * soap_decode(byte *param_1,int param_2,byte *param_3,undefined4 param_4)

{
  char cVar1;
  int iVar2;
  char cVar3;
  int iStack24;
  byte *pbStack16;
  byte *pbStack12;
  
  pbStack16 = param_3;
  while ((*pbStack16 != 0 &&
         (((*pbStack16 == 0x20 || (*pbStack16 == 9)) ||
          (iVar2 = strchr(param_4,*pbStack16), iVar2 != 0))))) {
    pbStack16 = pbStack16 + 1;
  }
  iStack24 = param_2;
  pbStack12 = param_1;
  if (*pbStack16 == 0x22) {
    while (((pbStack16 = pbStack16 + 1, *pbStack16 != 0 && (*pbStack16 != 0x22)) &&
           (iStack24 = iStack24 + -1, iStack24 != 0))) {
      *pbStack12 = *pbStack16;
      pbStack12 = pbStack12 + 1;
    }
  }
  else {
    while ((((*pbStack16 != 0 && ((*pbStack16 == 0xffffffff || (0x20 < *pbStack16)))) &&
            (iVar2 = strchr(param_4,*pbStack16), iVar2 == 0)) &&
           (iStack24 = iStack24 + -1, iStack24 != 0))) {
      if (*pbStack16 == 0x25) {
        if (pbStack16[1] < 0x41) {
          cVar1 = (char)((pbStack16[1] - 0x30 & 0xff) << 4);
        }
        else {
          cVar1 = ((pbStack16[1] & 7) + 9) * '\x10';
        }
        if (pbStack16[2] < 0x41) {
          cVar3 = pbStack16[2] - 0x30;
        }
        else {
          cVar3 = (pbStack16[2] & 7) + 9;
        }
        *pbStack12 = cVar1 + cVar3;
        pbStack16 = pbStack16 + 3;
        pbStack12 = pbStack12 + 1;
      }
      else {
        *pbStack12 = *pbStack16;
        pbStack16 = pbStack16 + 1;
        pbStack12 = pbStack12 + 1;
      }
    }
  }
  *pbStack12 = 0;
  while ((*pbStack16 != 0 && (iVar2 = strchr(param_4,*pbStack16), iVar2 == 0))) {
    pbStack16 = pbStack16 + 1;
  }
  return pbStack16;
}

but it's even older version without len check at all 🤔

你好，在使用webrtc的功能，需要到点问题，请教一下
我将 https://glitch.com/~openhisilicon 下载下来再局域网搭建，比如局域网ip 192.168.1.100,端口设置为8888

设置设备的webrtc_en:1, webrtc_url 为ws://192.168.1.100:8888/hiview-client,发现服务器有连接响应设备端一直提示

之后，一段时间之后

我想问一下，webrtc信令服务器必须搭建到公网吗?,搭建再局域网不行吗？
必须有ssl证书 使用wss://访问吗？
谢谢，期待回复

请问运行时的各模块的parm.json在哪里？有没有例子？

Can you please suggest me any tool where i could edit, debug and run this code.

If there is Hi3516dv300 imx335_2l.so driver or any code available?

在svp的VpssCapture类中，变量采用了static的定义方式，这样导致VpssCapture类会形成单例的功能。当我们希望多路算法切换不同的grp或者chn的时候，在任意一处修改VpssCapture中的参数，就会导致其它路算法使用的数据也被一起修改。
这里给出一个建议：
VpssCapture按照正常类的设计方式，去除所有的static定义。
在使用VpssCapture的是时候，采用类似static VpssCapture s_Vcap;这样的方式去避免不同算法引用VpssCapture的冲突问题。
以上修改在3516dv300的双sensor，多路算法中已验证可行。

ifconfig查看 发现dropped 和 overruns 两个数值不断增大

请问HIVIEW能够对接IPC的live stream么（比如海康的IPC）？因为后续需要送入mpp/svp进行处理，麻烦解答下，多谢！

Is there an example for how to use ae_piris_init, ae_piris_status_get functions?

It seems that they work with /dev/piris 🤔

Is there a way to make usb uart adapters work with something like HI3516DV300 ?

你好，我在使用onvif模块对接华为nvr时失败了；抓包显示onvif流程正常，在获取到rtsp播放地址之后播放失败(onplay之后客户端又发送了一个getparameter请求，然后就停下了)，请教一下有没有遇到过类似问题

由于没有arm-hisiv510-linux编译工具，将build中3536d对应交叉编译工具改为arm-hisiv400-linux
再使用

你好，我看到你的Mpp修改记录 有提到这个 < add imx415 60FPS for 3516DV300;> ，能提供一下这个驱动源码吗？
或者有什么方式 可以获得这个驱动代码

Very nice project!

But I only have one hi3516cv300 development board in my hand.

How to add support, thank you very much.

有在lvgl上测试过argb1555 吗？

b站上讲解webrtc signaling那块的视频是不是被删除了？找不到啦

如题，使用不同版本的编译器或者库去链接是否有兼容性问题，比如020和030的不同版本？

http.c 和signling.c都有调用webrtc_proc,http.c处理是本地的webrtc连接，signaling.c是处理https://openhisilicon.glitch.me/ 的webrtc连接吗？

你好，如图 运行codec.exe，当选择imx415 sony415驱动打印这个错误提示信息 。是不415 不支持dv300的60fps吗？
顺便问一下 ，imx415 能配置成5M吗？

官方和srs中的state_thread中epoll中对EPOLLET没有直接支持. 我尝试做了如下修改
ST_HIDDEN int _st_epoll_pollset_add(struct pollfd *pds, int npds) { ... if (events != old_events) { op = old_events ? EPOLL_CTL_MOD : EPOLL_CTL_ADD; ev.events = events | EPOLLET; ev.data.fd = fd; if (epoll_ctl(_st_epoll_data->epfd, op, fd, &ev) < 0 && (op != EPOLL_CTL_ADD || errno != EEXIST)) break; if (op == EPOLL_CTL_ADD) { _st_epoll_data->evtlist_cnt++; if (_st_epoll_data->evtlist_cnt > _st_epoll_data->evtlist_size) _st_epoll_evtlist_expand(); } } ... }
EPOLLET没有起效. 后来使用原生的接口调用时正常的. 请问一下, 这个是什么原因导致的?

使用开源的libst库交叉编译后, epoll监听端口处理连接请求会出现段错误.
初步分析 _x86_64 架构正常， __arm__架构编译会有问题
怀疑问题出在md.h中 _st_md_cxt_restore 和 _st_md_cxt_save这两个接口的问题
线程中上下文信息保存和还原 数据丢失了

海康大华需要下载工具才能支持web的rtsp流播放，HIVIEW是直接支持web播放还是也要安装软件才能播放？谢谢
