Master's explanation: Why is the 35-year-old C ++ still dominant in the development field? Bjarne Stroustrup designed the C ++ language in 1979, and this general-purpose language for system programming has become one of the preferred solutions for developers around the world. Despite the frequent impact from Java, JavaScript, Python, Go, and the Swift language just announced by Apple, C ++ remains stable and lofty.As a technical expert at Morgan Stanley investment and a professor at

RTSP protocol analysis1. Overview:RTSP (Real Time Streaming Protocol) is an application layer Protocol in the TCP/IP Protocol system. It is an ietf rfc standard submitted by Columbia University, Netscape and RealNetworks. This Protocol defines how one-to-multiple applications can effectively transmit multimedia data over an IP network. It is similar to the HTTP traffic control protocol. Both use plain text to send information, and the rtsp protocol sy

It is a multimedia description protocol from a client to a server.RTSP is an application layer protocol that is very similar to HTTP. Each release and media file is also defined as RTSP upl. The publishing information of a media file is written into a file called a media publishing file, which will be described later.
