An RTMP Server (Real-Time Messaging Protocol Server) is a software application that facilitates the streaming of audio, video, and data over the internet. It is commonly used for live broadcasting and allows content creators to send their media to the server, which then distributes it to viewers in real-time. This protocol is particularly popular for platforms like YouTube and Twitch. RTMP servers work by establishing a persistent connection between the client and the server, enabling low-latency streaming. They support various codecs and formats, making them versatile for different types of media content. Additionally, RTMP can be used in conjunction with other protocols, such as HLS (HTTP Live Streaming), to enhance streaming capabilities.
