- 这是一个基于海康威视EHome SDK(v4.0)的实时推流工具，它能够对支持EHome SDK(v4.0)平台的IPC设备或者NVR设备的原始RTP流（海康私有RTP协议）进行协议转化，变为RTMP协议流，并推送到RTMP流媒体服务器，而后使用基于Flash插件的播放器进行网页端实时播放，从而最终实现Web端实时视频监控。
- 参考了CSDN上@雷霄骅的部分博客，在此向雷神致敬！
- 这也是我硕士课题的一部分，目前已经测试通过投入正式运行的环境是：
- IPC型号: DS-2CD2T25FD-I3W/R
- 云服务器规格: 阿里云ECS(Ubuntu 16.04 LTS 64位)
- Web端播放器: JW Player
- RTMP流媒体服务器: nginx-rtmp-module
- Web服务器: Nginx
- 部分型号的NVR已经通过测试，能否稳定运行还需要进一步测试。
- 部署和预览请求协议注意点已经在下面deploy tips和REQ_SRV protocol列出。
- 附上本人硕士毕业拙文作为参考
- 基于实时推流工具的风机叶片测试过程视频监控[J]
- 风机叶片测试远程监控系统[D]
- 由于本人水平有限，也希望大家指出我的不足，多提提意见，一起来完善这个项目，实现大家想要的功能。>_<
A push kit of RTMP based on HikVision's EHome SDK(v4.0) that can accept the registration of HIK's IPCs and push streaming to RTMP server. Once there is a preview request, this kit can collect the streaming and transform the private RTP into RTMP, and then push it to any RTMP server, such as Red5 or nginx-rtmp module. Hence the real time monitoring.

It very strange that the link tool--ldd still can't find the libhpr.so dynamic library even if I use -L(hik_ehomelib_path) and -l(hik_ehomelib_name) in makefile. So you need to add hik_ehomelib_path into /etc/profile to make the executable program can be created successfully.
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:(your_path)/HIKPusher/HIK_EHome/eh_lib/
The request from web in the form of socket is now following the format:
"start:IPCS00000x0x"
so you need to set the EHome account of HikVision IPC with the format of "IPCS00000x0x", and the first 'x' refers to location, the second one refers to number in this location in order to distinguish every IPC.
The settings above is mine, and you can also set your own protocol, which must change the function IPCS_GetInt_Devid() in ipc/ipcs.c so as to parse out correct IPC dev_id(EHome account).
- Finish the decoding of private RTP to H264 streaming.
- Finish the encoding of H264 streaming to RTMP.
- Combine the dec-enc and HIK's EHome SDK.
- Add a server that used to listen and accept the preview requests. Use heart beat packet to collect the requests.
- Add "ipcs.c", use the global array variable "IPCs[]" to storage every ipc's infos: login_id, dev_id, push rtmp handle, etc.
- Add the signal handler function of signal "ctrl + c", hence the release of all memory resources such as req_srv buf and ipc's push buf when use "ctrl + c" to exit the main function. As a result, some variables has changed to global ones due to the reference in signal handler function.
- Change every ipc's rtmp url, the end of url is dev_id.
- Change the rtmp ip macro to two: "0.0.0.0" and public net ip.
- Fix the bug when free ipc's push resources.
- Change the project name(from "eh_rtmp_demo" to "HIKPusher").
- Add each ipc's info: metadata, send flag, tick, etc. when send h264, so as to distinguish different ipcs. And modify each ipc's push_free function.
- Because of the loop contains between h264-rtmp.h and ipcs.h, move the definition of RTMPMetadata to ipcs.h.
- Change the directions of the project.
- Add the record module(./record) of the project, hence the log files which can record the problems when running.
- Change the macro name of ipc's states.
- Fix some bugs about the judgements of ipc's states.
- Change the file name of ps/h264 parser and some function name in 'conv' to look more clear.
- Change the struct _ipc, remove 'm_pFileBuf' because its duplication with 'full_h264pack'.
- Change some functions in parser_h264.c, especially H264_SendToRtmp, to make it more simple.
- Change the return value of functions in parser_ps.c.
- Simplify many functions and data structures in the whole project.
- Change log.c, divide logs into different types--INFO, WARN, ERROR, DEBUG.
- Change the format of record: [INFO/WARN/ERROR/DEBUG time]([error_num]) <line_num><func_name> content
- Fix some mutex bugs when save log files.
- Due to the truncation of PS packs during transmission, use two parse buffer: pespack_buf and h264pack_buf in struct _ipc to storage a complete pes pack or h264 pack for the following parse.
- Clarify the parse process into two parser: PS_Parser and H264_Parser, and make them a chain.
- May be used in different kinds of HIK devices...
