What is Red5?

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

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.

CasparCG Server vs Red5: editorial side-by-side

C0.0

CasparCG 2.5.1 drops the AVX2 floor it set in 2.5.0 and moves to FFmpeg 8.1.

◆ Current state

CasparCG Server is an open-source broadcast playout server shipping one or two stable releases a year. 2.5.1 (September 16) removes the AVX2 requirement except for v210 Decklink output, updates FFmpeg to 8.1.2, and adds multi-device audio output, configurable audio and screen delays and an option to disable Decklink keying. 2.5.0 in December 2025 brought initial HDR, headless Linux and Ubuntu packaging.

◆ Where it's heading

After 2.5.0 set new baselines, 2.5.1 walks back the hardware one and spends the rest on stability: FFmpeg error handling, an AMCP BATCH race and Decklink av-sync recovery. The pattern is a feature-heavy .0 followed by fix-heavy point releases.

◆ Prediction

Expect further 2.5.x point releases before any 2.6 work appears; the entries show no 2.6 betas yet.

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.
