RTMP (Real-Time Messaging Protocol) is a TCP-based protocol developed by Adobe Systems for efficient transmission of audio, video, and data over the internet. It is commonly used for streaming multimedia content, particularly in live streaming applications.

RTMP operates on a client-server model, where the client establishes a connection with a server using the RTMP protocol. It supports low-latency communication and enables real-time interaction between the client and server.

RTMP is widely used in various streaming platforms and services, including video sharing websites, online gaming, and live event broadcasting. It offers reliable and scalable streaming capabilities, making it a popular choice for delivering high-quality multimedia content over the internet.
