What is Red5?

Red5 ships constantly and explains almost none of it.

Red5 is a Java media server built around RTMP ingest and delivery. Releases come every few days — nine tags between early May and early July — but most publish nothing beyond an auto-generated link to the commit range. Two version schemes run side by side, with v2.0.16.46 appearing in July while the v2.0.3x series was still incrementing through June, so the tag number alone does not tell you which line a build belongs to.

What is SRS?

SRS opens a 7.0 line built on a Go proxy tier, and drops features it no longer wants to carry.

SRS shipped the stable 6.0 line's first release on 12 August and, three hours later, the first development build of 7.0. The 6.0 line is now in pure maintenance — the r1 changelog is seven merges of DVR, WebRTC and edge fixes. Everything new is in 7.0-d0: RTSP playback, RTMPS, IPv6 across every protocol, HEVC in both directions between RTMP and WebRTC, and HLS fMP4 segments for HEVC and LL-HLS.

Red5 vs SRS: editorial side-by-side

2.5

Red5 ships constantly and explains almost none of it.

◆ Current state

Red5 is a Java media server built around RTMP ingest and delivery. Releases come every few days — nine tags between early May and early July — but most publish nothing beyond an auto-generated link to the commit range. Two version schemes run side by side, with v2.0.16.46 appearing in July while the v2.0.3x series was still incrementing through June, so the tag number alone does not tell you which line a build belongs to.

◆ Where it's heading

Where changelogs do exist, the work is concentrated in the RTMP hot path: cutting CPU waste and allocation churn on ingest, then addressing thread oversubscription three releases later. The one capability addition visible in this window is AV1 support. Everything else that is described is dependency maintenance — Spring, Bouncy Castle — and build plumbing like on-demand Docker image pushes. The pattern is a small maintainer group optimising a mature server rather than repositioning it.

◆ Prediction

Expect the RTMP performance thread to continue and AV1 handling to be refined in follow-up releases. The undocumented releases make anything beyond that guesswork — the changelogs would need to carry content before a direction could be read from them.

6.3

SRS opens a 7.0 line built on a Go proxy tier, and drops features it no longer wants to carry.

◆ Current state

SRS shipped the stable 6.0 line's first release on 12 August and, three hours later, the first development build of 7.0. The 6.0 line is now in pure maintenance — the r1 changelog is seven merges of DVR, WebRTC and edge fixes. Everything new is in 7.0-d0: RTSP playback, RTMPS, IPv6 across every protocol, HEVC in both directions between RTMP and WebRTC, and HLS fMP4 segments for HEVC and LL-HLS.

◆ Where it's heading

The project is trading breadth of legacy surface for a narrower, better-covered core. 7.0-d0 removes the embedded GB28181 SIP server, multi-threading, Cygwin, and most configuration hot reload, while introducing a Go proxy server and origin-cluster architecture alongside the C++ media core. Protocol coverage keeps generalizing — each release makes a codec or an address family a property of the server rather than of one delivery path.

◆ Prediction

Expect the 7.0 line to run a long alpha and beta train the way 6.0 did, with the Go proxy and origin clustering carrying most of the remaining work and 6.0 continuing to receive backported fixes in parallel.
