First, the introduction of the Darwin development document to introduce a section of the circulation of the pull mode and push mode:
Darwin supports two types of automatic transmissions: first pull and then push. To initiate an automatic broadcast, the RTSP customer sends a standard RTSP request to request a stream from the server, and the server relays the stream to one or more streaming media servers. Thi
number is the same, then by B to Ep-r Porta send the connection request, if ep-r have a response, then Ep-r no IP and port restrictions, belong to the Conenat type.
Step Fifth: If there is no response, Then Server B uses its new Port B ' to send a connection request to the Ep-r PORTB port, and if so, it indicates that the EP-R is restricted to IP only and is of a restrictive conenat type;
The above five steps can basically detect whether the ep-r is in the public net or behind some kind of Nat.

Onvif:
Onvif specifications describe network video models, interfaces, data types, and Data Interaction modes. And reuse some existing standards, such as the WS series standards. The onvif specification aims to implement a network video Framework Protocol, so that network video products (including video recording front-end and video equipment) produced by different manufacturers are completely interconnected.The interfaces defined in the device management and control section of the onvif spec
(i) Red5 Streaming Media Server IntroductionRed5 is an open source Flash streaming media server with Java development. It supports: Convert audio (MP3) and video (FLV) to play stream, record client stream (FLV only), share object, live stream release, Remote call. Red5 uses RSTP as the streaming media transport protocol, and in some of its own examples, it demonstrates some of the basic features of online recording, Flash streaming, live chat, video conferencing, and more.(ii) Introduction of th
When developing with the FFmpeg class library, the function that opens the streaming media (or local file) is Avformat_open_input ().If you open the network stream, you should precede the function avformat_network_init ().In general, you can just pass in the URL of the streaming media. However, when you open some streaming media, you may need to attach some parameters.For example, when playing a China National radio sound signal, its URL is "rtsp://mm

2. Use Haikang to preview the video with the ActiveX control itself.

Unlike HTTP streaming, Real-Time Streaming requires a dedicated Streaming Media Server and transmission protocol. Real-time stream transmission is always transmitted in real time, which is especially suitable for on-site events and supports random access. Users can fast forward or backward view content.
