What is RTMP?

RTMP denotes Real Time Messaging Protocol which initially was a protocol owned and designed by Macromedia for audio streams has also gained a lot of popularity due to its flawless video streaming. With the introduction of HTTP video streaming, RTMP video streaming nearly went obsolete at a point. But RTMP has several advantages which still make it the most used protocol to date.

What is RTMP streaming?

If one had to define RTMP, it can be easily stated that RTMP is an Adobe owned protocol who had taken the rights from Macromedia. RTMP can be used for streaming videos is FLV as well as MP4 formats. It also has the capability of streaming audio in MP3 and AAC formats. Live streaming as well as on-demand streaming is also supported by RTMP. RTMP servers include Wowza and Adobe Flash Media.

How does RTMP streaming work?

RTMP is basically based on TCP (Transmission Control Protocol).

In a specific situation, the correspondence is set up between the Adobe Flash Media Server (FMS) and the Client Flash Player.

What is RTMP protocol?

RTMP protocol is adaptable and can deliver Video and Audio (and TEXT! Keep in mind it takes into consideration a different text track to send along) in various configurations and to different Devices like Mobiles (except for iDevices which don’t “comprehend” Flash) and Web Applications. The upside of RTMP is that all Video and Audio documents are sent to a swf (small web format) file which can be played in a Flash Player, which reversely can be implanted in a Web Page or even Mobile Devices.

In a simple setup for the budding visionary, the Adobe Flash Media Server must be implanted first to encourage the transmission of Video or Audio information. At the point when a Flash Player installed towards the End User side makes a call to the FMS, it (the Flash Media Server) sends a swf file, which lives on the Server, back to the Player.

The Video and Audio files are all embedded in this swf file format and along these lines you can send Video or Audio in any possible format and still playback in a similar Flash Player.

RTMP Streaming, in any event in a homely setup, can be accomplished without the loss of sweat. The way toward installing and setting up a Flash Media Server is quite easy and the technology is brilliant since it has been around for a long time now. You can transmit Video and Audio in different formats and interpretations, and additionally apply Security Features, for example, Player Verification.

Adding to that, a standout feature amongst the most critical points of interest of RTMP, with regards to Live Broadcasts, is the low latency that is achieved while broadcasting a video. HTTP based Technologies present high latencies like 10+ seconds more and that just can’t work with outrageous live transmissions, for example, sport events, betting events, trading related Applications.

There’s a whole other world to the bundle of RTMP’s advantages over HTTP. Well it might sound bad but it is a fact that not all devices on earth today are front line Technology.

We should talk Set Top Boxes for instance without the mention of a couple of astounding exemptions, we are discussing obsolete boxes pressed with Stone Age old Hardware and Software. These do “comprehend” RTMP streaming and includes every feature that is required.

Still RTMP is used worldwide to date and has not gone obsolete. This is because of a few reasons.

  • Most streaming devices support RTMP so that they can deliver to CDN providers and servers which stream video content. In order to deliver a live video shot with a mobile camera, some native cellular applications use RTMP archives.
  • One of the most notable advantages of RTMP streaming is that it has the capability to commence an advanced search. With a real-time streaming protocol, the player can look for a lesser latency than HTTP enabled video streams. A Flash Player is required to relish this feature.
  • RTMP can encourage different levels of content insurance, from falsified to genuine DRM (Digital Rights Management). For PC browser playback, the program does not store RTMP streams in their cache.
  • One of the favored talents of RTMP is versatile streaming playback, wherein numerous bitrates and resolutions of content are given to a video player, empowering the best resolution to play in the given current system speeds. Certain HTTP streaming innovations, for example, HLS and MPEG-DASH help in a similar delivery system, yet RTMP can be more responsive when it comes to changing with one bit-rate then onto the next. Sadly, there is no standard for HTTP versatile streaming across browsers that would support HTML5 video.
  • While live streams don’t need to be versatile, a similar rule of bundled video section applies to any live stream playback. Almost all live streaming occasions for in-browser PC playback require a video player that backs Flash-based rendering and RTMP playback.
  • The browser for Apple i.e. Safari on iOS locally supports HLS, and luckily, all cutting edge streaming servers, including Wowza Streaming Engine, support RTMP and HLS packetizing. The urgent need for Flash Player with live streaming will just change when MPEG-DASH moves toward becoming as influential as Flash is today. In the event that Internet Explorer 8, 9, and 10 supports are required for your live streaming arrangement, RTMP streaming will remain at the top. Additionally, on the off chance that you require close to zero latency on a live stream, HTTP streaming will most probably not address your issues while RTMP can. HTTP tools require more bundles to collect on the server before sending them to the video player.

RTMP is basically an old and foolproof streaming technology that has been used for years now. The Flash Player which helps in viewing video streams through RTMP protocol is quite famous and used all over the planet. There are certain drawbacks of RTMP that has been found out, however, it still remains a platform favored by most.

In conclusion, it must be noted that if your focus lies entirely upon 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.
