preface

I haven't updated it for a long time. One is that I don't have time. The other is that I may pay more attention to an opportunity. I'm afraid to write wrong in semi familiar fields, and I dare not write in too familiar fields. Only things I just touch dare to write indiscriminately.

Well, it's just the sentence that newborn calves are not afraid of tigers. To get back to business, this article mainly records the initial use process and some problems encountered during WVP + zlmedia kit.

1, WVP

WEB VIDEO PLATFORM It is an out of the box network video platform based on GB28181-2016 standard. It is responsible for realizing the background part of core signaling and equipment management, supporting NAT penetration, and supporting IPC, NVR and DVR access of Haikang, Dahua, Yushi and other brands. Support national standard cascading, forward video streams such as rtsp/rtmp to the national standard platform, and push streams such as rtsp/rtmp to the national standard platform.

1.1. WVP operation

Installing the Java development environment
Install Redis( windows installation package point I download，centos installation tutorial point I open)
Clone and import the project (it is recommended to clone the project directly from git clone instead of downloading the zip file directly from the web page)
Modify the configuration file (application dev.yml)

spring:
    # REDIS database configuration
    redis:
        # [must be modified] Redis server IP, REDIS is installed on the local computer, and 127.0.0.1 is used

Run the test (Note: install the zlmedia kit and run it first)
WVP2.0 has integrated the web interface. The first time you run npm Install and build, and then run WVP project, you can directly access the web page.
Problems encountered
When adding an agent device, an error is reported. Check the console output as follows.

Troubleshooting reason: the parameter name should be the same as the sql condition name in the mapped file. At the same time, add notes, modify it as follows and run it again.

2, Zlmedia Kit

ZLMediaKit Based on C++11 development, avoid the use of bare pointers, the code is stable and reliable, and the performance is superior.
Support multiple protocols (RTSP/RTMP/HLS/HTTP-FLV/WebSocket-FLV/GB28181/HTTP-TS/WebSocket-TS/HTTP-fMP4/WebSocket-fMP4/MP4/WebRTC), and support protocol exchange.
Developed with multiplexing / multithreading / asynchronous network IO mode, it has superior concurrency performance and supports massive client connections.
After a large number of long-term stability and performance tests, the code has been commercially verified online for a long time. Support linux, macos, ios, android and windows platforms.
It supports the second opening of the picture and very low delay (within 500 milliseconds, up to 100 milliseconds at least). Provide perfect standard C API, which can be used as SDK or called by other languages.
Provide a complete MediaServer server, which can be directly deployed as a commercial server without development. Provide complete restful api and web
hook, which supports rich business logic. Through the video monitoring protocol stack and live broadcast protocol stack, the RTSP/RTMP support is perfect.
Fully support H265/H264/AAC/G711/OPUS.

2.1. Run zlmedia Kit

You can download it directly My installation package (centos) , unzip and run.

./MediaServer -d &

Of course, you can compile it yourself and check the details given by the boss wiki document , the screenshot of the operation is as follows (404 is returned when you don't have any content, which is successful).
