GB28181监控系统

一、部署示意图/架构图/框图

1) 2D

3D)

二、gb28181设备接入gb28181服务器总览

1、下载Hikvision Tools（含SADP、录像容量计算等工具）

https://www.hikvision.com/cn/download_more_393.html?_blank

扫描摄像头，更改ip，与电脑在同一网段。

2、摄像头gb28181协议配置

1#摄像头

2#摄像头

3#摄像头

3、gb28181下级平台服务器接入摄像头

gb28181服务器调试工具下载，50个积分，这tm在打劫呀，也可以用公安部的spvmn，就是太难用了，IE控件也播不了rtp的ps流。

4、也可以用公安部的SPVMN(1.0.0.1版软件包里有应用手册，其他版本好像没有)

三、gb28181系统sip信令通道

1. Resources used

sip server + sip user agent

sip server: freeswitch / freepbx

sip user agent: libexosip2-5.1.0/tools/sip_reg.c

2. Install freeswitch

1) FreeSWITCH Explained

https://freeswitch.org/confluence/

https://freeswitch.org/confluence/display/FREESWITCH/CentOS+7+and+RHEL+7

https://freeswitch.org/confluence/display/FREESWITCH/CentOS+7

2) step by step:

Install FreeSWITCH 1.6.0 on CentOS 7 (fresh installation):

Note: Everything below is run inside CentOS 7 terminal as "root" user (via "su -" command)

1) Make sure yum update is run and CentOS is up-to-date
2) {optional} inside Terminal window select Edit Profile Preferences and select "Use custom default terminal size" and make it 160 x 60.  Close terminal and re-open for the change to take affect.
3) yum -y install git
4) yum -y install epel-release
5) rpm -Uvh http://files.freeswitch.org/freeswitch-release-1-6.noarch.rpm
6) yum -y install git gcc-c++ autoconf automake libtool wget python ncurses-devel zlib-devel libjpeg-devel openssl-devel e2fsprogs-devel sqlite-devel libcurl-devel pcre-devel speex-devel ldns-devel libedit-devel libxml2-devel
7) yum -y install libyuv-devel opus-devel libvpx-devel libvpx2* libdb4* libidn-devel unbound-devel libuuid-devel lua-devel libsndfile-devel
8) cd /usr/local/src
9) git clone -b v1.6 https://freeswitch.org/stash/scm/fs/freeswitch.git
10) cd /usr/local/src/freeswitch
11) ./bootstrap.sh
12) ./configure
13) make
14) make install
15) make cd-sounds-install
16) make cd-moh-install
17) cd /usr/local/freeswitch/conf
18) vi vars.xml
    Change:  <X-PRE-PROCESS cmd="set" data="default_password=1234"/> {!!set it to something different!!}
    Save and close (<Esc> :wq!)
19) cd /usr/local/freeswitch/conf/sip_profiles
20) mv internal-ipv6.xml internal-ipv6.xml.removed   {disables ipv6 support}
21) mv external-ipv6.xml external-ipv6.xml.removed  {disables ipv6 support}
22) cd /usr/local/freeswitch/bin
23) ./freeswitch -nonat -nonatmap
24) ... to exit from FreeSWITCH console

3) Quickly install

yum install -y http://files.freeswitch.org/freeswitch-release-1-6.noarch.rpm epel-release
yum install -y freeswitch-config-vanilla freeswitch-lang-* freeswitch-sounds-* systemctl enable freeswitch freeswitch

4) source install

3. Build libexosip2-5.1.0.tar.gz + libosip2-5.1.0.tar.gz

四、gb28181系统媒体数据通道

1、ps流封包

有人整理了而且经验证是靠谱的，我就不干重复劳动了。

https://github.com/shenshuyu/es2ps

测试demo，填EsFrame , 回调函数出ps

void PsMuxerCb(char* psData, unsigned long dataLen, unsigned int lastPackMark){

}

int main(int argc, char **argv) { EsFrame *frame = (EsFrame *)malloc(sizeof(EsFrame)); MuxerHandle m = create_ps_muxer(PsMuxerCb, NULL); input_es_frame(m, frame); release_ps_muxer(m); free(frame); return 0; }

2、ps流解包

可以用ffmpeg解析ps流，源码包里有两个示例都可以将ps解析成h264

ffmpeg-4.1/doc/examples/remuxing.c

ffmpeg-4.1/doc/examples/transcoding.c

以上例子是解析文件，改成缓存可以参考

https://www.cnblogs.com/dong1/p/9575291.html

3、media-server太给力了，啥都做好了，rtp/flv/ps/ts/es/h264全都处理好了！

https://github.com/ireader/media-server

https://github.com/licaibiao

我需要的一部分整理出来

https://files.cnblogs.com/files/dong1/gb28181_test.zip

https://files.cnblogs.com/files/dong1/rtp_ts_send_recv.zip

从PS流获取H264

https://www.xilixili.net/2018/05/11/parse-hikvision-camera-ps-stream/

4、基于jrtplib的rtp收发

虽然ffmpeg也可以做rtp收发，但是jrtplib包里有现成的，有现成的，有现成的。

下面的例子注释掉h264过滤，可以收发任意格式的rtp包

https://files.cnblogs.com/files/dong1/jrtplib_send_recv_h264.zip

jrtplib在ubuntu下的编译安装

https://blog.csdn.net/wang3141128/article/details/80482849

5、ps解析g711

在mpeg-ps-dec-test.cpp示例(支持ps解析h264视频和aac音频)的基础上加了个g711音频的解析

#include "mpeg-ps.h"
#include "mpeg-ts-proto.h" #include <stdio.h> #include <assert.h> #include <stdlib.h> #include <string.h> static FILE* vfp; static FILE* afp; static FILE* gfp; inline const char* ftimestamp(int64_t t, char* buf) { if (PTS_NO_VALUE == t) { sprintf(buf, "(null)"); } else { t /= 90; sprintf(buf, "%d:%02d:%02d.%03d", (int)(t / 3600000), (int)((t / 60000) % 60), (int)((t / 1000) % 60), (int)(t % 1000)); } return buf; } static void onpacket(void* /*param*/, int /*stream*/, int avtype, int flags, int64_t pts, int64_t dts, const void* data, size_t bytes) { static char s_pts[64], s_dts[64]; if(PSI_STREAM_AAC == avtype) { static int64_t a_pts = 0, a_dts = 0; if (PTS_NO_VALUE == dts) dts = pts; //assert(0 == a_dts || dts >= a_dts); printf("[A] pts: %s(%ld), dts: %s(%ld), diff: %03d/%03d\n", ftimestamp(pts, s_pts), pts, ftimestamp(dts, s_dts), dts, (int)(pts - a_pts) / 90, (int)(dts - a_dts) / 90); a_pts = pts; a_dts = dts; fwrite(data, 1, bytes, afp); } else if(PSI_STREAM_AUDIO_G711 == avtype) { static int64_t a_pts = 0, a_dts = 0; if (PTS_NO_VALUE == dts) dts = pts; //assert(0 == a_dts || dts >= a_dts); printf("[A] pts: %s(%ld), dts: %s(%ld), diff: %03d/%03d\n", ftimestamp(pts, s_pts), pts, ftimestamp(dts, s_dts), dts, (int)(pts - a_pts) / 90, (int)(dts - a_dts) / 90); a_pts = pts; a_dts = dts; fwrite(data, 1, bytes, gfp); } else if (PSI_STREAM_H264 == avtype) { static int64_t v_pts = 0, v_dts = 0; assert(0 == v_dts || dts >= v_dts); printf("[V] pts: %s(%ld), dts: %s(%ld), diff: %03d/%03d\n", ftimestamp(pts, s_pts), pts, ftimestamp(dts, s_dts), dts, (int)(pts - v_pts) / 90, (int)(dts - v_dts) / 90); v_pts = pts; v_dts = dts; fwrite(data, 1, bytes, vfp); } else { //assert(0);  } } static uint8_t s_packet[2 * 1024 * 1024]; int main(int argc, char **argv) { FILE* fp = fopen("full.ps", "rb"); vfp = fopen("v.h264", "wb"); afp = fopen("a.aac", "wb"); gfp = fopen("a.g711", "wb"); size_t n, i= 0; ps_demuxer_t* ps = ps_demuxer_create(onpacket, NULL); while ((n = fread(s_packet + i, 1, sizeof(s_packet) - i, fp)) > 0) { size_t r = ps_demuxer_input(ps, s_packet, n + i); memmove(s_packet, s_packet + r, n + i - r); i = n + i - r; } ps_demuxer_destroy(ps); fclose(fp); fclose(vfp); fclose(afp); fclose(gfp); }

6、 rtmp推送

1）用的开源srs_librtmp，文档介绍

https://github.com/ossrs/srs/wiki/v2_CN_SrsLibrtmp#publish-h264-raw-data

2) 关于srs_rtmp_lib推流细节做了个笔记

https://www.cnblogs.com/dong1/p/5100792.html

3）这里边涉及到音视频组帧

SPS帧起始码 00 00 00 01 67

PPS帧起始码 00 00 00 01 68

I帧起始码 00 00 00 01 65

P帧分片码 00 00 00 01 41

if(FindStartCode(p))
{
    printf("h264 payload +++ %x %x %x %x %x\n",p[0],p[1],p[2],p[3],p[4]); ringput(buf, pos + bytes); pos = 0; memcpy(&(buf[pos]),p,bytes); pos = pos + bytes; } else { memcpy(&(buf[pos]),p,bytes); pos = pos + bytes; }
