Slow, engineering-led cadence on an open-source video stack — every post is protocol-level work.

video-conferencingopen-sourcewebrtcav1-codecperformancesip-interop
◆Current state
Jitsi's blog publishes irregularly — the six recent posts span more than a year — but the entries themselves are protocol-level engineering: codec defaults, SSRC rewriting, SIP bridges, receiver-side bandwidth controls. The output reads as a stack maintained by people more interested in WebRTC internals than in marketing.
◆Where it's heading
Across the visible window the work converges on one problem: make large WebRTC calls perform on commodity infrastructure. AV1 by default, SSRC rewriting, and receiver audio subscriptions all push in that direction. Interop work (SIP, Flutter SDK, integrations) sits around the edges as community-driven additions.
◆Prediction
Expect more bandwidth-and-scale work and continued hardware-meeting-room interop through SIP. With GSoC plugged in again for 2025, the adjacent capability surface keeps getting filled in by contributors rather than by a directional product roadmap.

    Introducing Receiver Audio Subscriptions

    Extends the long-standing video ReceiverConstraints mechanism to audio, letting receivers request specific streams. Continues the bandwidth-and-scale work that has dominated the recent Jitsi engineering posts.

    AV1 and more … how does Jitsi Meet pick video codecs?

    ⚡ SPARK

    Switches the default video codec in Jitsi Meet to AV1, with a deeper post explaining how the codec picker works. Changing the default is a deliberate architectural step toward better compression at scale.

    Connecting anything to everything via SIP

    Documents SIP integration letting hardware phones, softphones, and conferencing systems join Jitsi meetings. Meaningful interop work but inside the long-established 'connect everything' arc.

    Improving performance on very large calls: introducing SSRC rewriting

    Introduces SSRC rewriting to reduce backend load on very large calls. Part of the same large-call-performance theme that runs through receiver audio subscriptions and the AV1 default.

    Jitsi + Moodle, with a dash of JaaS

    Integration tutorial for embedding Jitsi (via JaaS) inside Moodle courses, driven by a community contribution from UDIMA. Useful integration content; no protocol or product surface change.
