BigBlueButton vs Wowza: at a glance
What is BigBlueButton?
BigBlueButton 4.0 enters release candidate with LiveKit fully replacing the legacy audio stack.
BigBlueButton is in its final stretch to 4.0 GA, with three release candidates shipping in September 2026. The 4.0 release is a near-complete architectural rebuild: LiveKit has replaced SIP.js and mediasoup as the default media transport, BlockNote replaced the old shared notes engine, and the mobile layout was overhauled. RC2 shipped security fixes for a cross-meeting presentation injection vulnerability, urging immediate admin updates.
What is Wowza?
Wowza is rebuilding around one idea: run computer vision inside the streaming pipeline.
Wowza's feed is a marketing blog, not a changelog — every entry is a short teaser ending in an ellipsis, with the substance behind the link. Read for direction rather than scope, it is almost entirely about the Video Intelligence Framework: object detection, scene analysis, vision-language models, synthetic video detection, and custom model support, all running on the same media server that ingests and delivers the stream. The one release-shaped item in this window remains NVIDIA's Synthetic Video Detector shipping as a VIF module; the newest post is a customer story rather than a capability.

BigBlueButton 4.0 enters release candidate with LiveKit fully replacing the legacy audio stack.
◆ Current state
BigBlueButton is in its final stretch to 4.0 GA, with three release candidates shipping in September 2026. The 4.0 release is a near-complete architectural rebuild: LiveKit has replaced SIP.js and mediasoup as the default media transport, BlockNote replaced the old shared notes engine, and the mobile layout was overhauled. RC2 shipped security fixes for a cross-meeting presentation injection vulnerability, urging immediate admin updates.
◆ Where it's heading
The LiveKit migration that began in 3.x security patches has culminated in rc.1's 'LiveKit as audio state source' refactor — the legacy audio path is gone. Multi-room sessions with membership-based tokens and automatic token refresh enable scenarios (breakout listen-in, large conferences) that the old bridge couldn't cleanly support. A 4.0 GA release is imminent given the RC cadence.
◆ Prediction
4.0 GA will ship within 2-3 weeks based on the RC pace. Post-GA focus will shift to hardening the LiveKit multi-room session model and expanding BlockNote capabilities (Markdown export landed in beta.4; more collaborative editing features likely next). The successful migration may influence other open-source video conferencing projects still running legacy SFU stacks.
Wowza
6.3MEETINGS
Wowza is rebuilding around one idea: run computer vision inside the streaming pipeline.
◆ Current state
Wowza's feed is a marketing blog, not a changelog — every entry is a short teaser ending in an ellipsis, with the substance behind the link. Read for direction rather than scope, it is almost entirely about the Video Intelligence Framework: object detection, scene analysis, vision-language models, synthetic video detection, and custom model support, all running on the same media server that ingests and delivers the stream. The one release-shaped item in this window remains NVIDIA's Synthetic Video Detector shipping as a VIF module; the newest post is a customer story rather than a capability.
◆ Where it's heading
Wowza is repositioning from media server to inference point, and the marketing has shifted from explaining the idea to proving it. The earlier posts argued that analysis belongs inside the pipeline rather than in a second system downstream; the recent ones supply a named deployment — Oceaneering running VIF on live subsea ROV video — and press the installed base still on Streaming Engine 4.8 to upgrade. A reference account and upgrade pressure arriving together is what a vendor does when it is converting an existing base rather than chasing new ones.
◆ Prediction
With a named customer now published and upgrade pressure already applied, expect more vertical case studies in industrial and infrastructure monitoring rather than new VIF capability announcements. The teaser-only feed will not reveal VIF pricing or packaging.
