The simplest example of Flash-based streaming media: RTMP push and receipt (ActionScript) and rtmpactionscriptThis article records some Flash-based streaming media processing examples.

This article records some examples of flash-based streaming media processing. The most common streaming media protocol for the Flash platform is rtmp. Some of the previously documented RTMP players/boosters are based on C + +, but no rtmp player/ejector based on ActionScript in Flash was recorded. In fact, the RTMP player/ejector based on Flash is a "regular" in rtmp technology. RTMP itself is designed to c

Real-time Streaming protocol RTSP (Realtimestreamingprotocol) is proposed by RealNetworks and Netscape, which defines how a one-to-many application can efficiently transfer multimedia data over an IP network. RTSP is located on the architecture of RTP (real-time transmission) and RTCP (real-time control), which uses TCP or RTP to complete the data transfer. HTTP transmits HTML compared to RTSP, while RTP transmits multimedia data. HTTP requests are se
