CasparCG Server vs Restream: at a glance
What is CasparCG Server?
Broadcast playout server reaches for HDR and sets a hardware floor to get there
CasparCG Server ships stable releases roughly once or twice a year, with long RC and beta runs ahead of each major. The 2.4 line delivered resolution and control-surface breadth — 8K and 4K DCI frames, custom resolutions, an interlaced mixer pipeline for field accuracy, AMCP command batching. The current 2.5.0 stable turns to colour and deployment: initial HDR support, ffmpeg 7.0, headless Linux operation, and Ubuntu deb packaging.
What is Restream?
Restream is pushing past creator multistreaming into webinars and agent control.
The core multistreaming product is now surrounded by three distinct expansions: a clips pipeline that ingests public Drive, Dropbox, and OneDrive links and autoposts highlights above a chosen virality score; a public API exposing viewer and chat analytics per destination; and an MCP server that lets an AI assistant drive streams in plain language. Destination coverage keeps widening at the edges, with Patreon, Rumble, and embedded web players all promoted to first-class channels. Cadence is steady at roughly one substantive change a week.

Broadcast playout server reaches for HDR and sets a hardware floor to get there
◆ Current state
CasparCG Server ships stable releases roughly once or twice a year, with long RC and beta runs ahead of each major. The 2.4 line delivered resolution and control-surface breadth — 8K and 4K DCI frames, custom resolutions, an interlaced mixer pipeline for field accuracy, AMCP command batching. The current 2.5.0 stable turns to colour and deployment: initial HDR support, ffmpeg 7.0, headless Linux operation, and Ubuntu deb packaging.
◆ Where it's heading
The project is modernizing the parts of a playout server that determine whether it can sit in a current broadcast chain — colour pipeline, pixel format fidelity, and where it can run. That comes with an explicit hardware bargain: AVX2 is recommended now and becomes a requirement in 2.6, trading compatibility with pre-2013 CPUs for the instruction set HDR and the embedded Chrome renderer need. Alongside, Decklink and NDI integration keep absorbing steady fix work.
◆ Prediction
2.6 should complete the AVX2 transition and widen HDR beyond the current subset of producers and consumers, since the 2.5 notes describe HDR as deliberately partial.
Restream

Restream is pushing past creator multistreaming into webinars and agent control.
◆ Current state
The core multistreaming product is now surrounded by three distinct expansions: a clips pipeline that ingests public Drive, Dropbox, and OneDrive links and autoposts highlights above a chosen virality score; a public API exposing viewer and chat analytics per destination; and an MCP server that lets an AI assistant drive streams in plain language. Destination coverage keeps widening at the edges, with Patreon, Rumble, and embedded web players all promoted to first-class channels. Cadence is steady at roughly one substantive change a week.
◆ Where it's heading
Two moves stand out against the routine destination-adding. The Slack town hall and webinar release aims the existing Studio at internal and B2B video, a different buyer from the creators Restream was built for. The MCP server aims the opposite direction, making the product addressable by agents rather than through its own interface, with Studio, Clips, and upload tools named as next. Together with the public analytics API, the pattern is a product deciding it is infrastructure as much as an application.
◆ Prediction
The stated MCP roadmap covering Studio, Clips, and video uploads is the most concrete next step, likely arriving alongside the promised one-click connection apps.
