The Real-Time Messaging Protocol (RTMP) is a communication protocol developed by Adobe for streaming audio, video, and data over the internet. It is primarily used for delivering content from a server to a client in real-time, making it ideal for live broadcasts and interactive applications. RTMP supports low-latency streaming, which is crucial for activities like online gaming and live events. RTMP operates over a persistent connection, allowing for continuous data transfer. It can transmit various types of media, including Flash video and H.264 video formats. Although its popularity has declined with the rise of newer protocols like HTTP Live Streaming (HLS), RTMP remains relevant in specific use cases, particularly in live streaming scenarios.
