CasparCG Server vs rtpengine: at a glance
What is CasparCG Server?
CasparCG 2.5.1 drops the AVX2 floor it set in 2.5.0 and moves to FFmpeg 8.1.
CasparCG Server is an open-source broadcast playout server shipping one or two stable releases a year. 2.5.1 (September 16) removes the AVX2 requirement except for v210 Decklink output, updates FFmpeg to 8.1.2, and adds multi-device audio output, configurable audio and screen delays and an option to disable Decklink keying. 2.5.0 in December 2025 brought initial HDR, headless Linux and Ubuntu packaging.
What is rtpengine?
rtpengine backports a DTMF header-extension fix to mr26.0 and mr26.3.
Sipwise's rtpengine shipped a batch of SRTP, ICE, Opus and Redis fixes to four branches on November 2. Two days later, mr26.0.1.28 and mr26.3.1.3 carry a single fix that leaves room for the RTP header extension when adding DTMF packets.

CasparCG 2.5.1 drops the AVX2 floor it set in 2.5.0 and moves to FFmpeg 8.1.
◆ Current state
CasparCG Server is an open-source broadcast playout server shipping one or two stable releases a year. 2.5.1 (September 16) removes the AVX2 requirement except for v210 Decklink output, updates FFmpeg to 8.1.2, and adds multi-device audio output, configurable audio and screen delays and an option to disable Decklink keying. 2.5.0 in December 2025 brought initial HDR, headless Linux and Ubuntu packaging.
◆ Where it's heading
After 2.5.0 set new baselines, 2.5.1 walks back the hardware one and spends the rest on stability: FFmpeg error handling, an AMCP BATCH race and Decklink av-sync recovery. The pattern is a feature-heavy .0 followed by fix-heavy point releases.
◆ Prediction
Expect further 2.5.x point releases before any 2.6 work appears; the entries show no 2.6 betas yet.
rtpengine
5.0MEETINGS
rtpengine backports a DTMF header-extension fix to mr26.0 and mr26.3.
◆ Current state
Sipwise's rtpengine shipped a batch of SRTP, ICE, Opus and Redis fixes to four branches on November 2. Two days later, mr26.0.1.28 and mr26.3.1.3 carry a single fix that leaves room for the RTP header extension when adding DTMF packets.
◆ Where it's heading
The project ships fixes in synchronized batches across every supported branch and reserves new behaviour for the newest line. Recent work clusters on encryption correctness, ICE negotiation edge cases and Redis-backed call recovery.
◆ Prediction
Follow-up builds on these branches within days are likely, as after the October 16 batch, along with further mr26.3 builds.
