Webcasting is an emerging social networking method that is popular because of its convenience, interactivity, and real-time. The public participation is extremely high.
From the technical principle, the realization of webcasting mainly includes video capture, video capture, video encoding, and video streaming. That is, at the same time of video shooting, video encoding technology is used to encode and compress the video source. Converted to IP stream), and then transmitted to the Internet live broadcast platform through the network, the viewer can watch in real time on the network side or the WeChat side. The live webcast completely broke the limitations of live TV broadcasts, and truly realized the lifestyle that everyone can broadcast live and can be broadcast live anytime, anywhere.
The most direct function of RTMP push-stream encoder: most commercial live broadcasts, the need to use multiple cameras and guides on site, then you need high-definition encoder to push, the signal is stable and high-definition, can guarantee the smooth flow of live broadcast .
When you are in live broadcast, you often need to set an RTMP server address in the network video encoder to facilitate RTMP push, which will push the encoded video information to the specified RTMP-enabled server, and then the viewer can access this address in real time. Watch the live stream. The RTMP server push address is usually obtained from the webcast service platform, such as betta. This part requires you to register the relevant live platform account yourself, and then open the corresponding live broadcast service to get the RTMP push stream address, in fact, it is also a live broadcast space. It starts with rtmp:// and consists of three parts: upload service address, upload directory name (APP) and upload node (stream).
RTMP is a network protocol for video streaming. A network protocol encoder is a signal that converts an SDI or HDMI source into a network stream. Qianshi Electronics has powerful streaming media service functions. In addition to supporting common protocols such as RTSP/RTMP, it also supports security Onvif protocol, SIP protocol, NDI protocol (customizable), GB/T28181 (customizable) and other RTP/RTSP/ RTMP/HLS/TS/Onvif/SIP/ NDI (customizable) / GB/T28181 (customizable) and other international streaming service protocols; support dual stream output, main stream supports up to 4K 30 Hz video Encoding, sub-stream support 720 p 60Hz video encoding, output resolution can be customized.
