Real Time Messaging Protocol RTMP Flash Streaming Server

Real Time Messaging Protocol RTMP

Flash Streaming Server communicates with its clients using the Adobe patented RTMP over TCP, which manages a two-way connection, allowing the server to send and receive, video, audio, and data between client and server

Configuration of RTMP- Standard, unencrypted RTMP. The default port is 1935. RTMPT- RTMP “tunneled” over HTTP The default port is 80 RTMPS- RTMP sent over an SSL enables secure TCP/IP connections. The default port is 443 RTMPE- Enhanced and encrypted version of RTMPTE- Encrypts the communication channel, tunneling over HTTP

Benefits of streaming There are three methods for delivering video over the Internet using Adobe Flash Player: • Progressive download • Streaming

Progressive download video delivery progressive download has been supported for video delivery. This method allows developers to load external video files into a Flash and play them back during runtime. When the video is played, the video file first begins to download to the user’s hard drive, then playback starts. The video begins to play when enough

Streaming delivery Streaming video, each client opens a persistent connection to the streaming server, and the server streams the video bits to the client. Those bits are displayed by the viewer and then immediately discarded

Why streaming is better Progressive download is a simple method of video delivery with very little control—it’s basically a simple HTTP download call. Streaming is a method that allows the publisher to control every aspect of the video experience.

Why streaming is better • Fast start—Streaming video is the fastest way to start playing any video on the web. • Advanced video control—Features such as bandwidth detection, quality-of-service monitoring. • Minimal use of client resources—Resources such as memory and disk space are significantly reduced with streaming, because the clients do not need to download and store the entire file.

Why streaming is better • Full seek and navigation—Users can seek to any point in the video and have it start playing immediately from that point. • Live video—Streaming provides the ability to deliver live video and audio from any connected

When to choose streaming • Deliver files longer than 30 seconds or larger than 100 Kbps • Perform bandwidth detection, allowing you to deliver the best quality video for the available hardware • Monitor quality-of-service • Perform real-time tracking

When to choose streaming • Provide real-time data sharing and interactivity to your video experiences • Stream live video and audio • Serve more streams with less bandwidth
