The technology behind live streaming<\/a> has evolved significantly in recent years. Adobe\u2019s Flash, a popular video player for decades, is now obsolete. Broadcasters<\/a> now use the ultra-compatible HTML5 video player<\/a> to deliver content to viewers.<\/p>

Real-Time Messaging Protocol (RTMP)<\/a> is a protocol that has remained important in the live streaming process throughout its evolution. There is one variation of this video streaming<\/a> protocol that is becoming more and more popular.<\/p>

RTMPS<\/a> is a variation of RTMP<\/a> that has an added layer of security in the form of TLS or SSL encryption, which is important since piracy and cybersecurity threats are on the rise. RTMPS<\/a> has evolved to help keep video streams<\/a> secure.<\/p>

This post will cover everything you need to know about RTMPS and its role in live streaming<\/a>. We will start by discussing the history and uses of RTMP<\/a> properly before discussing the ins and outs of RTMPS.<\/p>

From there, we will take a special look at RTMPS for mobile streaming<\/a> before we wrap things up by reviewing a few other RTMP variations and additional tools for protected streaming.<\/p>

RTMP: The History of the Real-Time Messaging Protocol<\/strong><\/p>

RTMP<\/a> has served several purposes in the live streaming<\/a> process over the years.<\/p>

Live streaming has evolved so much in recent years, and Real-Time Messaging Protocol (RTMP)<\/a> has played several roles in this transformation.<\/p>

Macromedia created this protocol back in 2002, the predecessor to Adobe, to deliver content from RTMP hosting servers<\/a> to the Flash video player. That function of the protocol is called \u201cRTMP delivery\u201d or \u201cRTMP streaming<\/a>.\u201d<\/p>

For many years, RTMP streaming<\/a> was the most popular live streaming<\/a> system. It delivered video content directly to the Adobe Flash player.<\/p>

However, the Adobe Flash player was not compatible with mobile streaming<\/a>, which meant people on a mobile device, such as a smartphone, couldn\u2019t access content that used Adobe\u2019s Flash player.<\/p>

But over the years, mobile users grew by leaps and bounds. Additionally, affordable data made it easy for people to browse the internet or watch videos<\/a> via their smartphones or tablets. In fact, more people now surf the internet using smartphones than other devices like laptops. Over 58.5% of global internet traffic now comes through phones.<\/p>

So naturally, as mobile viewing eclipsed computer viewing, this became a big problem, as more and more viewers couldn\u2019t access content that used Adobe\u2019s Flash player.<\/p>

Apple created a solution to this mobile video viewing issue by developing the HLS protocol<\/a>, which would work with the universal HTML5 video player<\/a>. HLS gradually replaced RTMP for live stream<\/a> delivery as Flash player phased out.<\/p>

However, RTMP still had a place in live streaming<\/a> systems that used HLS delivery<\/a>. RTMP ingest<\/a> was born, and the protocol was then used to transport video files from the encoder to the online video platform<\/a>. RTMP ingest allowed RTMP technology to live on with streaming video<\/a> content.<\/p>

RTMP ingest<\/a> is still the standard use of RTMP in live streaming. RTMP ingest<\/a> is valuable for broadcasters because it supports low-latency streaming and is made possible by low-cost RTMP encoders. In fact, it\u2019s one of the best protocols for low-latency streaming<\/a> even today.<\/p>

The Basics of How RTMP Streaming Works<\/strong><\/p>

RTMP<\/a> is a TCP-based communication protocol for two-way data, audio, and video<\/a> communication. It works by creating a communication pathway between the RTMP client and an RTMP server<\/a>; this allows data to be quickly transmitted.<\/p>

RTMP breaks video<\/a> content into smaller fragments to make it easier to transmit the data. Audio is generally split into 64 bytes and video into 128 bytes. The exact size of the fragments can vary.<\/p>

Breaking the content into small fragments allows the data to be quickly and effectively transmitted during a single connection, increasing the overall quality of your content.<\/p>

How the RTMP Connection Works<\/strong><\/p>

With RTMP<\/a>, a communication pathway is established between the client and the server<\/a>, called the connection set-up. The connection set-up consists of three different parts:<\/p>
