CasparCG Server vs Whereby: 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 Whereby?
Whereby ships monthly digests aimed squarely at the embedding developer, not the meeting host.
The feed is a run of monthly SDK and product round-ups, consistently framed around developer experience rather than end-user features. The specifics that do surface are embedding-side: session ratings for call quality feedback, session insights, stronger authentication options, and a native iOS SDK that left beta earlier in the year.

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.
Whereby
2.5MEETINGSCOLLAB
Whereby ships monthly digests aimed squarely at the embedding developer, not the meeting host.
◆ Current state
The feed is a run of monthly SDK and product round-ups, consistently framed around developer experience rather than end-user features. The specifics that do surface are embedding-side: session ratings for call quality feedback, session insights, stronger authentication options, and a native iOS SDK that left beta earlier in the year.
◆ Where it's heading
Whereby is a video product sold to developers who embed it, and the cadence reflects that: incremental SDK work, quality telemetry and authentication rather than the in-meeting AI features that dominate the conferencing category. The digest format itself is the notable pattern, since it bundles a month of changes behind a generic headline and makes individual releases hard to assess from the feed alone.
◆ Prediction
Expect continued monthly SDK round-ups with quality and telemetry themes; the entries carry too little detail to predict a specific capability with confidence.
