SRS vs Element Call: at a glance
What is SRS?
SRS 6.0 went stable by making H.265 work everywhere, not just in one protocol.
SRS shipped 6.0 release 0 in December 2025, promoting the 6.0 line to stable in place of 5.0 at roughly 170,000 lines of code. The headline is H.265/HEVC carried across RTMP, HTTP-FLV, HLS, HTTP-TS and SRT, with DVR recording to both MP4 and FLV. WebRTC gained WHEP for playback, stereo Opus over SDP and a configurable AAC-to-Opus bitrate; SRT moved to libsrt 1.5.3 with round-trip latency reported down to 200ms.
What is Element Call?
Matrix's calling app stopped negotiating which server hosts a call and let federation do it
Element Call spent June switching its default to a multi-SFU model: every participant connects to the media server attached to their own homeserver, and streams from other homeservers are pulled in subscribe-only. That removes the negotiation step that used to decide which single SFU a whole call would run on. July since then has been surface work — a default gradient background, retiring the last colors from the old design system, and mobile layout fixes for landscape one-on-one and grid modes.

SRS 6.0 went stable by making H.265 work everywhere, not just in one protocol.
◆ Current state
SRS shipped 6.0 release 0 in December 2025, promoting the 6.0 line to stable in place of 5.0 at roughly 170,000 lines of code. The headline is H.265/HEVC carried across RTMP, HTTP-FLV, HLS, HTTP-TS and SRT, with DVR recording to both MP4 and FLV. WebRTC gained WHEP for playback, stereo Opus over SDP and a configurable AAC-to-Opus bitrate; SRT moved to libsrt 1.5.3 with round-trip latency reported down to 200ms.
◆ Where it's heading
The eighteen months of alpha and beta tags before release 0 were overwhelmingly crash, leak and iterator fixes — smart-pointer conversions, use-after-free repairs in the HLS and bridge paths, RTC-to-RTMP stability. That is the signature of a project stabilizing an existing engine rather than extending it, with the codec work landing at the end. SRS is positioning as the self-hosted streaming server that speaks every ingest and egress protocol in one binary.
◆ Prediction
With 6.0 now the stable line, the pattern from the 5.0 era points to a run of 6.0 patch releases carrying fixes rather than features. The entries give no indication of what the next major line targets.

Matrix's calling app stopped negotiating which server hosts a call and let federation do it
◆ Current state
Element Call spent June switching its default to a multi-SFU model: every participant connects to the media server attached to their own homeserver, and streams from other homeservers are pulled in subscribe-only. That removes the negotiation step that used to decide which single SFU a whole call would run on. July since then has been surface work — a default gradient background, retiring the last colors from the old design system, and mobile layout fixes for landscape one-on-one and grid modes.
◆ Where it's heading
The multi-SFU switch is the project finishing what federated calling implies: no participant's call quality should depend on which homeserver happened to win a negotiation. It was compatible for six months before becoming the default, and legacy single-SFU mode is still reachable in developer settings, which is how infrastructure changes get made in an ecosystem of independent operators. With that settled, attention has visibly moved to mobile presentation and design-system consolidation.
◆ Prediction
Expect the legacy single-SFU path to be retired once operators have migrated, and the mobile layout work to continue through the 0.23 line. Note that every entry here is a release candidate, so these tags mark what is being tested rather than what operators are running.
