What is RTMP-In and RTMP-Out?

Real-Time Messaging Protocol (RTMP) is a specialized communication protocol that enables the low-latency transmission of live video and audio data across the internet. Developed by Macromedia, RTMP was designed to interact with Adobe Flash Player and became the de facto standard for sending live video content. Today, it serves as a link between encoder software and streaming platforms or media servers. The protocol's primary qualities of low latency and stability make it an important tool in live streaming. Understanding RTMP In (ingest) and RTMP Out (output) is crucial for setting up live streams. Encoders employ RTMP to transfer encoded video data to the platform for distribution and playing on viewers' devices.
