What is RTMP

• Introduction to RTMP Streaming

What is RTMP

• Real-Time Messaging Protocol (RTMP) was initially
  a proprietary protocol developed
  by Macromedia for streaming audio, video and data
  over the Internet, between a Flash player and a
  server. Macromedia is now owned by Adobe.

How does RTMP work?

• RTMP is based on TCP (Transmission Control
  Protocol). In a sample scenario, the
  communication is established between the Adobe
  Flash Media Server (FMS) and the Client Flash
  Player. RTMP protocol is versatile and can
  deliver Video and Audio (and TEXT! Dont forget
  it allows for a separate text track to send
  along) in numerous formats and to various Devices
  like Mobiles (but, generally, iDevices which
  dont understand Flash) and Web Applications.
  The advantage of RTMP is that all Video and Audio
  files are sent to a swf file which can be played
  in a Flash Player, which in turn can be embedded
  in a Web Page or even Mobile Devices.

Pros of the RTMP protocol

• RTMP delivers on-demand and live media to Adobe
  Flash applications such as audio and video
  streaming in addition to real-time communications
  platforms.
•  RTMP sets up an interaction between a client and
  a server. RTSP enables end users to control media
  session by means of simple commands such as play,
  pause, and stop. Moreover, it allows clients to
  watch video from any fragment without waiting for
  complete download.
• When it comes to Live Broadcasts, is the very low
  latency/delay from real time in transmission

Cons of the RTMP Streaming

• RTMP does support HTML5
• RTMP has broad DRM support
• RTMP protocol is that its vulnerable to
  bandwidth issues. Sometimes, low bandwidth may
  cause interruptions in media streaming or even
  stream may not start if Internet connection speed
  is not enough.
• RTMP is always more of a no-go when applying for
  Streaming CDN Services

Technical overview of RTMP Streaming

• The Adobe Flash Media Server has to be installed
  first to facilitate transmission of Video or
  Audio data. When a Flash Player installed at the
  End User end makes a call to the FMS, it (the
  FMS) sends a swf file, which resides on the
  Server, back to the Player. The Video and Audio
  files are inserted in this swf file and therefore
  you can send Video or Audio in any convenient
  format and still playback in the same Flash
  Player.

Alternatives to RTMP

• HLS HTTP Live Streaming (also known as HLS) is
  an HTTP-based media streaming communications
  protocol implemented by Apple Inc to deliver
  video to Apple devices like the iPad and iPhone.
• HDS HDS, or HTTP Dynamic Streaming is a
  futuristic streaming format created by Adobe,
  intended to be used along with Flash. It hasnt
  gained as much relative momentum, however.
• MPEG-DASH One of the most recently innovated
  protocols, MPEG-DASH presents many merits.
  Entirely HTTP-based, it allows broadcasters to
  implement its framework faster than ever before.

Conclusion

• It must be noted that if your focus lies entirely
  upon flash based live streaming then RTMP is
  surely the protocol which you give your venture a
  successful future. HTTP streaming has become
  quite widespread as well, but it can never
  include the features that RTMP streaming have
  implanted in it.
