mediasoup vs Fourwaves: at a glance
What is mediasoup?
mediasoup is threading subchannels through pipe transports, one small Rust release at a time.
The Rust crate ships small, frequent releases carrying one or two commits each. A single thread runs through the current window: subchannel support over pipe transport, which started with encoding subchannels into SCTP messages in 0.23.0, continued with pipe DataConsumers handling them in 0.24.2, and reached the API surface in 0.25.0 with an ignored_subchannel argument on DirectDataProducer.send(). Alongside it, 0.24.0 was a security batch — constant-time comparison for SCTP cookie and STUN message-integrity MACs, an out-of-bounds write in RTP dependency descriptor parsing, an SCTP integer overflow — with an outside researcher credited on all three.
What is Fourwaves?
Fourwaves is turning the event site into a live wayfinding surface for attendees
Fourwaves runs the full lifecycle of academic and scientific conferences: submissions, registration, program, certificates and the event website itself. The current window is almost entirely attendee-side: the event home now surfaces which sessions are live and which are next, and presentations can be pushed onto a personal agenda straight from the session list. On the organizer side the theme is tolerance rather than capability - missing data in certificates and participant records now raises warnings instead of halting the job.

5.0MEETINGS
mediasoup is threading subchannels through pipe transports, one small Rust release at a time.
◆ Current state
The Rust crate ships small, frequent releases carrying one or two commits each. A single thread runs through the current window: subchannel support over pipe transport, which started with encoding subchannels into SCTP messages in 0.23.0, continued with pipe DataConsumers handling them in 0.24.2, and reached the API surface in 0.25.0 with an ignored_subchannel argument on DirectDataProducer.send(). Alongside it, 0.24.0 was a security batch — constant-time comparison for SCTP cookie and STUN message-integrity MACs, an out-of-bounds write in RTP dependency descriptor parsing, an SCTP integer overflow — with an outside researcher credited on all three.
◆ Where it's heading
The work is squarely on multi-worker and multi-host routing: subchannels let a single data stream be selectively delivered, and making that work across pipe transport is what lets it survive the hop between workers. That is scaling infrastructure for SFU operators running mediasoup across processes or machines rather than a feature end users see. The parallel security hardening suggests the library is getting outside scrutiny, and the SVC enablement for VP8 and H264 in 0.22.11 rounds out the same picture — media quality and routing capability for large deployments.
◆ Prediction
Expect the subchannel work to continue closing gaps in the pipe transport path, since each release in this sequence has handled one more place subchannels were dropped. The one-or-two-commit release habit means version numbers will keep climbing faster than the scope of any individual change.

Fourwaves is turning the event site into a live wayfinding surface for attendees
◆ Current state
Fourwaves runs the full lifecycle of academic and scientific conferences: submissions, registration, program, certificates and the event website itself. The current window is almost entirely attendee-side: the event home now surfaces which sessions are live and which are next, and presentations can be pushed onto a personal agenda straight from the session list. On the organizer side the theme is tolerance rather than capability - missing data in certificates and participant records now raises warnings instead of halting the job.
◆ Where it's heading
Two arcs run in parallel. The first is in-event orientation: after the direct-messaging rollout and the mobile app soft launch that opened this month, the live-and-upcoming panel and agenda shortcuts are the web-side half of keeping attendees moving during the event rather than before it. The second is unblocking organizers - the deliberate downgrade of missing-variable and missing-data errors from blockers to warnings shows a team removing hard stops from workflows that run under conference-day time pressure.
◆ Prediction
Expect the mobile app to move from soft launch toward general availability with the agenda and live-session views as its core screens, and the warning-instead-of-error treatment to spread to the remaining organizer workflows that still hard-fail on incomplete data.
