Fourwaves vs SRS: at a glance
What is Fourwaves?
Fourwaves doubles Free plan submissions to 50 and reworks reviewer assignment.
Fourwaves ships small dated updates most days. November 11 raised the Free plan from 25 to 50 submissions, and November 12 added a four-step Assign reviewers window. Earlier in November it brought offline mobile check-in for Pro organizers and saved email templates for Advanced and Pro.
What is SRS?
SRS now runs three release lines at once and publishes A/B CPU benchmarks with each build.
SRS, the open-source media streaming server, cut v6.0-r3, v7.0-a4 and v8.0-d3 within two minutes on 31 October. Each release now carries an A/B CPU benchmark across 16 delivery scenarios: 6.0-r3 trims 4-6% CPU on RTMP, HTTP-FLV and HTTP-TS, while both 7.0-a4 and 8.0-d3 show RTSP delivery using about 30% more CPU than the prior build. Release commits are co-authored with Claude.
Fourwaves vs SRS: editorial side-by-side
Fourwaves
5.0MEETINGS
Fourwaves doubles Free plan submissions to 50 and reworks reviewer assignment.
◆ Current state
Fourwaves ships small dated updates most days. November 11 raised the Free plan from 25 to 50 submissions, and November 12 added a four-step Assign reviewers window. Earlier in November it brought offline mobile check-in for Pro organizers and saved email templates for Advanced and Pro.
◆ Where it's heading
Most releases go to organizer tools for running the event and the review process, with features gated to paid plans. The Free plan increase is the first move in this run that widens the entry tier rather than adding to paid ones.
◆ Prediction
Expect more steps in the submission and review workflow to follow the new reviewer window; whether the Free plan change is part of a wider pricing revision is unclear from the entries.
SRS
5.0MEETINGS
SRS now runs three release lines at once and publishes A/B CPU benchmarks with each build.
◆ Current state
SRS, the open-source media streaming server, cut v6.0-r3, v7.0-a4 and v8.0-d3 within two minutes on 31 October. Each release now carries an A/B CPU benchmark across 16 delivery scenarios: 6.0-r3 trims 4-6% CPU on RTMP, HTTP-FLV and HTTP-TS, while both 7.0-a4 and 8.0-d3 show RTSP delivery using about 30% more CPU than the prior build. Release commits are co-authored with Claude.
◆ Where it's heading
Release engineering is becoming the product's visible discipline: stable, alpha and dev lines ship together with measured performance deltas rather than feature notes. The 7.0 line has moved from dev snapshots into alphas, and 8.0 now takes the dev-snapshot slot.
◆ Prediction
The shared RTSP regression in 7.0-a4 and 8.0-d3 is the obvious thing for the next alpha and dev builds to address, given the benchmarks now flag it on every release.
