Important

We recommend running CasparCG 2.5 on CPUs which support AVX2. Officially Chrome claims to require AVX2, and it is required for some of our in-progress HDR support.
Intel CPUs based on Haswell or later support this, which were first released to consumers in 2013, or 2014 for servers.

Starting with CasparCG 2.6, this will become a requirement.

Make sure to install the latest MSVC runtime, the compiler update requires a newer version than 2.4 https://aka.ms/vc14/vc_redist.x64.exe

Core

Improvements

• Initial support for HDR. This is limited to a subset of producers and consumers at this stage.
• Build for Windows with VS2022
• Rework linux builds to produce ubuntu deb files
• Update ffmpeg to 7.0
• Reimplement mixer transforms, to handle routes correctly
• Support more pixel formats from ffmpeg, to preserve colour accuracy better
• Support running on headless linux
• Transitions: Additional behaviours

Fixes

• Build with boost 1.85/1.86/1.87/1.88
• Build with ffmpeg 7.1
• Only produce mixed frames on channels which have consumers
• Routed channels not compositing correctly when channel used a MIXER KEY
• Handle audio for fractional framerates properly
• Gracefully exit on SIGINT and SIGTERM

Producers

Improvements

• FFmpeg: Support loading with a scaling-mode, to configure how clips get fit into the channel
• FFmpeg: Support more pixel formats without cpu conversion
• FFmpeg: Enable alpha for webm videos
• Image: Support loading with a scaling-mode, to configure how images get fit into the channel
• Image: Replace freeimage with ffmpeg
• HTML: Update CEF to 142
• HTML: Support audio

Fixes

• Route: Use full field rate when performing i->p channel route
• HTML: Gracefully handle page load errors
• HTML: Always set cache path

Consumers

Improvements

• Screen: Set size and position from AMCP
• Screen: Improve performance
• Image: Propagate AMCP parameters from PRINT command
• FFmpeg: Remove unnecessary forced conversion to YUVA422
• Decklink: Support explicit yuv output (requires AVX2)
• Decklink: Allow selecting device by hardware persistent id

Fixes

• FFmpeg: Correctly handle PTS on frame drop

Companion v4.2.0 - Release Notes

This is a slightly smaller release than usual, focussing more on smaller improvements.

End of support for macOS 11

This version of Companion requires macOS 12 or later

Rebuilt Documentation

The Companion User Guide has been rewritten to use a new rendering system.

This allows us to host a new publicly available version of the documentation online which is versioned per release, as well as building it in a simplified form within Companion

The new tools allow us to do more with the documentation and will make it easier for us to keep up to date too!

Improved Expression Editor

The expression editor input field has been rebuilt, making it easier to use with functionality you would expect from a code editor. This includes functions and keyword suggestions, and better handling of multi-line expressions.
