What is RTMP Streaming?
RTMP streaming is the process of transmitting video, audio, and data over the internet with latencies from sub-250ms to 3 seconds. Real-Time Messaging Protocol (RTMP) is a streaming protocol originally developed by Macromedia (later acquired by Adobe). Red5 was the first in the industry to reverse engineer RTMP, creating an open-source RTMP server alternative to Adobe’s Flash Communication server. Today RTMP streams continue to be one of the most common streaming video protocols both for RTMP servers and RTMP clients. Learn more in our “What is RTMP?” blog.

/
How is RTMP different from ERTMP?
Real-Time Messaging Protocol (RTMP) and Enhanced RTMP (ERTMP) are TCP-based protocols for streaming audio, video, and data. ERTMP, introduced in Red5 Pro v14.0, adds features like H.265 support, advanced codecs, and ultra-low latency while remaining backward compatible. Learn more in our ERTMP documentation.

What is an RTMP server?
An RTMP server receives video streams from an encoder and delivers them to viewers or other platforms for live broadcasting.
/
Does Red5 support single bitrate RTMP?
While the open-source Red5 RTMP server supports single-bitrate delivery, it does not include server-side transcoding. This capability is available in Red5 Pro and Red5 Cloud which enables adaptive bitrate (ABR) streaming for RTMP.
