Introduction :

RTMPS is an alternative to RTMP that uses extra security encryption to ensure that the stream is not intercepted by an unauthorized entity. The extra layer for security in RTMPS was either TSL or SSL encryption. RTMPS can be used with RTMP, as long as it is supported by your chosen broadcasting tools. It is useful for broadcasting on a public network. This protocol is more popular in streaming from a mobile device. Because of the added security which RTMPS provides, broadcasters prefer it in many situations.

The History of Real-Time Messaging Protocol :

This protocol was created by Macromedia, before to Adobe, to deliver content from RTMP hosting service to the Flash video player. This function of the protocol is called “RTMP delivery” or RTMP streaming. RTMP had a place in live streaming systems that used HLS delivery. RTMP and the protocol were used to transport video files from the encoder to the online video platform. RTMP is valuable for broadcasters because it supports low-latency streaming and it is made possible by low-cost RTMP encoders.

RTMPS working :

RTMP maintains a connection between the player client and server, which allows the protocol to act as a pipe and quickly moves video data to the viewer. As RTMP sits on top of the Transmission Control Protocol (TCP), it uses a three-way when transferring data. The client asks the server to start a connection, the server responds, then the client acknowledges the response and maintains a session between either end. Thus, RTMP is quite dependable.

RTMPS Mobile Streaming :

RTMPS is very important for mobile streaming for people who often stream on public internet networks. As the public, networks expose devices to other users who could hack them and create issues with security.

Facebook live is one of the most important streaming platforms which switches from using RTMP proper to the RTMPS protocol for live streaming. To avoid infiltration and external threads, they have noticed the trend in the use of public networks. Many experts in broadcasting have found that other major social streaming platforms are not yet using the RTMPS protocol even though their users are generally using mobile streaming. Since security breaches become more common they predict that heightened security may be applied to the content delivery network. If you are looking for a mobile live-streaming app to broadcast from your mobile, we highly recommend choosing one that supports RTMPS.

Securing the contribution stream with RTMPS :

Streaming software and hardware encoders use a data transfer protocol called RTMP. It’s reliable but it is not that secure. RTMP is prone to spoofing and other man-in-the-middle attacks. The threat of someone disrupts important live streaming . Using an RTMPS is the easiest way to keep live streaming content safe from spoofing and spying. The secure version of RTMP is RTMPS. The RTMPS streaming protocol allows you to stream securely by encrypting the stream between the encoder and the CDN, but also it protects against domain impersonation. A handshake is used between the sender and the receiver to authenticate that you’re sending your content to the right destination. But to use secure live streaming with RTMPS, both the video encoder that’s streaming the content and the CDN location you’re streaming to must support it.

Other RTMP Protocol Variations :

• RTMPS is not the only online video streaming RTMP-based solution. Let's see other variations
• RTMFP which is also known as Real-Time Media Flow Protocol that targets P2P resources, which needs a live video streaming feature too. It deals with the video communication of users in various chats.
• RTMPE (Real-Time Messaging Protocol Encryption) is reminiscent of the RTMPS protocol. As the name implies, this RTMP variation which also has higher security.
• RT MPT is attention-worthy, its main task is to bypass firewalls.

Multiplexing & Marketization :

Once the installation of RTMP has been completed and a proper connection has been established, the streaming content can be transmitted. RTMP’s standards for packetizing and multiplexing audio and video data which is critical in delivering a smooth media streaming experience. The terms are very complicated, but the concepts behind them are too straightforward. Multiplexing merges and separates audio and video data into a single audio-video stream that can be transmitted at the same time. If you have worked with a video or audio editing software system, you can think of this process as analogous to mixing down and exporting a multi-track project to one media file On receipting, interleaved data must be disassembled, or demultiplexed, to the original audio and video data.

Advantages of RTMP streaming:

• It is used for low latency streaming.
• It creates a quick streaming experience by maintaining constant contact between the video player and the server.
• It provides secure, cloud-based streaming through RTMPS.

Disadvantages of RTMP streaming :

• It doesn’t support high-resolution videos and video compressions.
• If any network issues occur, it can quickly lose data over a few seconds, which can disrupt the stream.

### Summary:

RTMPS is a most valuable protocol for broadcasters who want to keep their streams protected and secure. It works as exactly as RTMP, but it has an added layer of security. This protocol is useful for streaming from mobile devices as it provides the external security needed for protected streaming on public networks.
