mediasoup vs SRS: at a glance
What is mediasoup?
After weeks of one-line subchannel patches, mediasoup rebuilt its RTCP timing model.
The Rust line had been shipping single-PR point releases every few days, nearly all of them subchannel plumbing for DataConsumers over pipe transports plus the occasional crash fix. 0.26.0 breaks that pattern with a seven-PR reworking of how RTCP Sender Reports are generated, moving them off RTP packet arrival time and onto an estimate of when the media was actually captured. The 0.24.0 release earlier in the window also carried real security work — constant-time MAC comparison and fixes for an OOB write and an SCTP integer overflow.
What is SRS?
SRS opens a 7.0 line built on a Go proxy tier, and drops features it no longer wants to carry.
SRS shipped the stable 6.0 line's first release on 12 August and, three hours later, the first development build of 7.0. The 6.0 line is now in pure maintenance — the r1 changelog is seven merges of DVR, WebRTC and edge fixes. Everything new is in 7.0-d0: RTSP playback, RTMPS, IPv6 across every protocol, HEVC in both directions between RTMP and WebRTC, and HLS fMP4 segments for HEVC and LL-HLS.

6.3MEETINGS
After weeks of one-line subchannel patches, mediasoup rebuilt its RTCP timing model.
◆ Current state
The Rust line had been shipping single-PR point releases every few days, nearly all of them subchannel plumbing for DataConsumers over pipe transports plus the occasional crash fix. 0.26.0 breaks that pattern with a seven-PR reworking of how RTCP Sender Reports are generated, moving them off RTP packet arrival time and onto an estimate of when the media was actually captured. The 0.24.0 release earlier in the window also carried real security work — constant-time MAC comparison and fixes for an OOB write and an SCTP integer overflow.
◆ Where it's heading
Two threads run through this window: finishing the subchannel mechanism so pipe transports behave like direct ones, and tightening timing correctness in the media path. The new RemoteClockOffsetEstimator and RemoteCaptureTimeEstimator classes, plus abs-capture-time rewriting in the simulcast manager, are foundations rather than endpoints — they give the worker a notion of remote capture instants it did not previously have. Expect that foundation to be used by more than Sender Reports.
◆ Prediction
The capture-time estimators look like groundwork for synchronization and delay features beyond Sender Reports; the near-term releases will likely be fixes shaking out the new timing path across simulcast and pipe transports.
SRS
6.3MEETINGS
SRS opens a 7.0 line built on a Go proxy tier, and drops features it no longer wants to carry.
◆ Current state
SRS shipped the stable 6.0 line's first release on 12 August and, three hours later, the first development build of 7.0. The 6.0 line is now in pure maintenance — the r1 changelog is seven merges of DVR, WebRTC and edge fixes. Everything new is in 7.0-d0: RTSP playback, RTMPS, IPv6 across every protocol, HEVC in both directions between RTMP and WebRTC, and HLS fMP4 segments for HEVC and LL-HLS.
◆ Where it's heading
The project is trading breadth of legacy surface for a narrower, better-covered core. 7.0-d0 removes the embedded GB28181 SIP server, multi-threading, Cygwin, and most configuration hot reload, while introducing a Go proxy server and origin-cluster architecture alongside the C++ media core. Protocol coverage keeps generalizing — each release makes a codec or an address family a property of the server rather than of one delivery path.
◆ Prediction
Expect the 7.0 line to run a long alpha and beta train the way 6.0 did, with the Go proxy and origin clustering carrying most of the remaining work and 6.0 continuing to receive backported fixes in parallel.
