What is SRS?

SRS now runs three release lines at once and publishes A/B CPU benchmarks with each build.

SRS, the open-source media streaming server, cut v6.0-r3, v7.0-a4 and v8.0-d3 within two minutes on 31 October. Each release now carries an A/B CPU benchmark across 16 delivery scenarios: 6.0-r3 trims 4-6% CPU on RTMP, HTTP-FLV and HTTP-TS, while both 7.0-a4 and 8.0-d3 show RTSP delivery using about 30% more CPU than the prior build. Release commits are co-authored with Claude.

What is Red5?

Red5 2.2.0 makes JDK 25 the minimum after a run of thinly documented patches.

Red5 is a Java media server built around RTMP. Red5 Server 2.2.0 made JDK 25 the baseline, cleaned removed JVM flags out of the launch scripts and fixed service setup, after 2.0.49 made the AMF0 and AMF3 codecs spec-compliant. Tags such as 2.0.53 continue alongside it with no notes beyond a changelog link.

SRS vs Red5: editorial side-by-side

SRS
MEETINGS
5.0

SRS now runs three release lines at once and publishes A/B CPU benchmarks with each build.

◆ Current state

SRS, the open-source media streaming server, cut v6.0-r3, v7.0-a4 and v8.0-d3 within two minutes on 31 October. Each release now carries an A/B CPU benchmark across 16 delivery scenarios: 6.0-r3 trims 4-6% CPU on RTMP, HTTP-FLV and HTTP-TS, while both 7.0-a4 and 8.0-d3 show RTSP delivery using about 30% more CPU than the prior build. Release commits are co-authored with Claude.

◆ Where it's heading

Release engineering is becoming the product's visible discipline: stable, alpha and dev lines ship together with measured performance deltas rather than feature notes. The 7.0 line has moved from dev snapshots into alphas, and 8.0 now takes the dev-snapshot slot.

◆ Prediction

The shared RTSP regression in 7.0-a4 and 8.0-d3 is the obvious thing for the next alpha and dev builds to address, given the benchmarks now flag it on every release.

Red5
MEETINGS
5.0

Red5 2.2.0 makes JDK 25 the minimum after a run of thinly documented patches.

◆ Current state

Red5 is a Java media server built around RTMP. Red5 Server 2.2.0 made JDK 25 the baseline, cleaned removed JVM flags out of the launch scripts and fixed service setup, after 2.0.49 made the AMF0 and AMF3 codecs spec-compliant. Tags such as 2.0.53 continue alongside it with no notes beyond a changelog link.

◆ Where it's heading

After the patch run, Red5 is modernizing its runtime and packaging rather than adding media features. The servlet module is back in the build but not yet shipped, so finishing that packaging is the visible open item.

◆ Prediction

A 2.2.x follow-up that packages the servlet module (restoring RTMPT) and fixes service installs on JDK 25 is likely, since the 2.2.0 notes name both as known issues.
