What is the primary purpose of RTMP?

The primary purpose of RTMP, or Real-Time Messaging Protocol, is to facilitate live streaming. This protocol was originally developed by Macromedia (now owned by Adobe) to enable high-performance transmission of audio, video, and data over the internet, particularly for live streaming applications.

RTMP works by establishing a persistent connection that allows for low-latency transmission of media, which is essential for real-time communication scenarios such as live broadcasts, online gaming, and video conferences. It supports the streaming of live video content in a way that ensures viewers receive the stream with minimal delay, which is crucial for interactive sessions where viewer engagement is immediate.

While securing data transmission, optimizing database queries, and compressing video files are vital areas in computer science and media processing, they do not align with the core functionality of RTMP, which focuses specifically on delivering live audio and video content efficiently.
