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 Restream?

Restream's chat now keeps the full history and shows Super Chats and other stream alerts.

Restream's recent releases are about what happens around a stream rather than the encode itself. The November 8 update keeps every chat message, even when chat is opened late or gets thousands of messages, and shows stream alerts such as YouTube Super Chats and memberships, X follows and Kick subscriptions in the same panel. It follows Instagram Live by account connection with chat, and the Claude connector.

CasparCG Server vs Restream: editorial side-by-side

C0.0

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.

5.0

Restream's chat now keeps the full history and shows Super Chats and other stream alerts.

◆ Current state

Restream's recent releases are about what happens around a stream rather than the encode itself. The November 8 update keeps every chat message, even when chat is opened late or gets thousands of messages, and shows stream alerts such as YouTube Super Chats and memberships, X follows and Kick subscriptions in the same panel. It follows Instagram Live by account connection with chat, and the Claude connector.

◆ Where it's heading

The product is moving from a relay that forwards a video feed to a hub that owns the account connections, the audience data and the follow-up. Each release removes a manual step: stream keys, attendee lists, clip posting, and now opening the dashboard at all.

◆ Prediction

Expect more destinations to move from stream-key relay to direct account connections with chat, following the X and Instagram pattern. Whether the Claude connector grows into scheduled or automated stream workflows is not yet visible in the entries.
