Restream vs rtpengine: at a glance
What is Restream?
Restream's webinars get a registration page and a CSV of leads, turning broadcasts into a pipeline
Restream ships about one user-facing change a week across three surfaces: the live Studio (free element positioning, live edit mode, per-scene screen shares), destinations (X chat replies and analytics, Rumble clip publishing), and Clips, which now ingests public YouTube links. The newest release gives webinars a single registration-to-replay link and exports attendee names, emails, roles and registration details to CSV.
What is rtpengine?
rtpengine backports the same DTLS and socket fixes across four maintenance branches at once.
Sipwise's rtpengine media proxy is maintaining several release lines in parallel (mr13.5, mr14.1, mr26.0, mr26.1, mr26.2), and most recent entries are coordinated backports. The September 16 batch fixes hash-table updates, nested string lookups and stop_forwarding mixups across four branches, and adds DTLS negotiation corrections (setup=actpass logic, ignoring incorrect DTLS=passive, keeping TLS IDs on answer role changes) to the mr26.0 and mr26.1 lines.

◆ Current state
Restream ships about one user-facing change a week across three surfaces: the live Studio (free element positioning, live edit mode, per-scene screen shares), destinations (X chat replies and analytics, Rumble clip publishing), and Clips, which now ingests public YouTube links. The newest release gives webinars a single registration-to-replay link and exports attendee names, emails, roles and registration details to CSV.
◆ Where it's heading
The webinar line that launched in July inside Slack has its first follow-up, and it points at marketing use: capturing who registered, not just streaming to them. Alongside Clips taking outside sources, Restream is building around the broadcast on both sides, collecting audiences before it and repurposing footage after it. Studio work stays incremental polish for producers running multi-scene shows.
◆ Prediction
Expect webinar lead data to move beyond CSV export, likely into direct CRM or marketing-tool handoffs, plus more Clips sources and destinations. How far the webinar product goes into registration forms and attendee follow-up is not yet visible.
rtpengine
5.0MEETINGS
rtpengine backports the same DTLS and socket fixes across four maintenance branches at once.
◆ Current state
Sipwise's rtpengine media proxy is maintaining several release lines in parallel (mr13.5, mr14.1, mr26.0, mr26.1, mr26.2), and most recent entries are coordinated backports. The September 16 batch fixes hash-table updates, nested string lookups and stop_forwarding mixups across four branches, and adds DTLS negotiation corrections (setup=actpass logic, ignoring incorrect DTLS=passive, keeping TLS IDs on answer role changes) to the mr26.0 and mr26.1 lines.
◆ Where it's heading
The work is focused on correctness in media negotiation, especially DTLS role handling and ICE on closed sockets, rather than new features. The newest branch, mr26.2, also brought AMR fmtp defaults, mirroring of generated RTCP sender reports to Homer, and recording cleanup hardening, which points to better interop and observability for carrier deployments.
◆ Prediction
More synchronized backport releases across the mr13.5 through mr26.2 lines are the clear pattern; feature work will most likely keep landing on mr26.2 first.
