The current live broadcast of the mess, the various capitals desperately broke into, making the live broadcast industry smoke, all kinds of network red emerges endlessly, in order to publicize, Bo eyeball out of position, the platform even let the anchor use a variety of vulgar performances to attract the audience, in fact The live broadcast platform does not really make much money, and the live broadcast has a lot of pressure. The main reason is that live broadcasts take up a lot of traffic, and the live content is mostly the same, there is not much creativity, and relying on money to pull popularity can not find reasonable and legal for a long time. When it comes to profitability, it will be difficult to continue.
Here we talk about the technology used in live webcasting, namely streaming media technology. The development of streaming media technology has experienced nearly 20 years. With the increase of bandwidth and the improvement of compression technology, it brings more imagination to people. In fact, we can use streaming media technology to achieve applications such as teleconferencing, telemedicine, distance education, and kindergarten video surveillance live broadcast.
Early kindergarten monitoring live broadcast due to the high bandwidth cost, the technology is not mature, although it is good, but it is not a seat, although parents are willing to see the children at any time to pay, but because of the more complex technology, high network bandwidth costs, expensive equipment, making the operation successful Less.
The author has been engaged in the streaming media industry for more than ten years, witnessing the development of the industry and the development of various applications. We believe that it is currently possible to monitor the live broadcast of this project through technical means and low-cost operation of the kindergarten. The live broadcast of 1000 roads is not difficult, which provides the necessary technical support for the development of the kindergarten monitoring live broadcast project.
Recently, the Aoku Media Server that the author participated in was successfully used in the kindergarten monitoring live broadcast project operated by a company. There is no pressure on the single server to provide 206 live broadcasts at the same time. The 206 live broadcast also starts the rtmp, rtsp protocol, and also opens hls. Slice, the CPU is almost not occupied when the system is running stably, as shown below:
The 206 live spot is the rtsp stream of the NVR output distributed in different cities, or the rtsp stream output by the webcam. Through the cool streaming media service system software, these rtsp streams can be obtained, and rtmp forwarding is provided, rtsp Forwarding, as well as hls slicing, these streams are then embedded in various APPs or WeChat applications to meet the needs of watching live broadcasts on computers, TVs, and mobile phones at any time.
The cool streaming media service system is a high-performance streaming media software independently developed by Polar Star. The latest version is 5.0. The following is the function introduction:
1. Powerful:
Support all TCP/IP-based networks for broadcast, support IPV4 and IPV6 networks, support broadband Internet, mobile Internet and two-way TV networks to provide smooth video and audio broadcast to all types of terminals such as Windows terminals, ios terminals, Android terminals, TV boxes, etc. Out of service, providing broadcast services under HLS, HTTP, FLV_OVER_HTTP, TS_OVER_HTTP, TS, RTMP, RTSP, HTML5 and other specifications.
2. Easy to install:
AMS supports deployment in Windows, Linux, and arm-linux environments. It supports pure green installation-free operation. It does not need to be installed and deployed. It can be copied to the hard disk directory to run.
3. Wide range of applications:
With live TV, live broadcast, time-shifted TV, instant review and video on demand, it is suitable for classroom live broadcast, live broadcast, mobile TV, OTT TV, IPTV, Internet education, video chat, live broadcast and VOD.
4. Strong performance:
All adopt C development, IOCP is adopted under Windows, and EPOLL is adopted under Linux, which realizes that the ordinary server easily supports more than 3000 unicast concurrent streams.
5. The perfect combination of P2P HTTP:
AMS supports P2P live broadcast, and the independent acceleration plug-in provides more live broadcast receiving users. The original P2P and HTTP seamless switching technology ensures better network utilization and more concurrent user support.
6. Rich live mode:
AMS supports the establishment of multiple modes of live broadcast, including playback, normal live, insert, carousel, and broadcast modes. It is convenient for customers to establish multiple live applications. AMS playback uses original RTMP or HTTP playback technology to ensure The live broadcast supports playback back at low latency.
7. The program recording is powerful:
AMS supports powerful program recording functions and supports multiple forms of recording: streaming video (automatic segmentation), task recording, instant recording, etc., support for recording files in FLV and MP4 formats, AMS original technology to ensure the interruption of the recording process, Broken network and power off will not destroy the recorded files, and ensure the recording is complete.
8. Independent video control module:
AMS provides a separate recording control module that can record recorded channels to other platforms via FTP or HTTP according to pre-configuration, and can also analyze video tasks and rules sent by other platforms. Record and perform tasks according to the rules.
9. Strong scalability:
The system can be deployed in a single machine or in a cluster. The hardware and network facilities can be configured according to the application scale. The application can be scaled from thousands of concurrent to one million concurrent, from enterprise-level operation scale to carrier-class operation scale. The right is entirely in the hands of the customer.
10. Content Re-release Engine:
A powerful live stream re-release engine for distributing live streams and on-demand streams to other hosts in the service network to quickly synchronize content distribution in CDN networks and load balancing systems.
11. Powerful pull stream plugin:
Provide powerful pull stream and live broadcast release, which can broadcast live broadcast of rtsp streams of various webcams and NVRs, and support live broadcast of TS streams of satellite TVs, and output live streams of other streaming media service systems. Release, release can support secondary transcoding, adding watermarks and other operations.
12. Flexible transcoding engine:
The transcoding server can run independently or as a plug-in for streaming media services. It can be integrated with the streaming media server or deployed separately, providing online transcoding services, transcoding live streams and files, transcoding and streaming media. The server seamlessly connects, that is, broadcasts and broadcasts, supports cluster deployment of transcoding services, and provides manual transcoding and remote scheduling transcoding modes. Provide cover function when transcoding, can automatically extract cover of various specifications to meet various applications
13.HLS automatic slicing and packaging:
Automatically slice and package multimedia files and live streams in multiple formats, generate m3u8 index files, and output HLS broadcast streams. Time-shift playback and quick review can be achieved while outputting HLS live streams without additional development.
14. Secure broadcast and anti-theft chain capabilities:
Strict user authentication and playback authorization policies can provide content playback authorization only through authenticated users, encrypt sensitive content, and effectively resist theft and illegal access.
