Download for Windows — v0.1.45 Windows release notes

Windows installer (.exe)Recommended. Installs the plugin into your existing OBS Studio installation. Portable ZIP (x64)Unpack into the OBS plugin directory yourself — for locked-down or portable OBS setups. Installer checksumSHA-256 for the installer, to verify the download before running it. ZIP checksumSHA-256 for the portable archive. Companion moduleThe Bitfocus Companion module (corevideo-obs) ships with each release. Requires Companion v5 or newer.

v0.1.45 is the current Windows release and adds the Zoom Talkback dock and the panelist loudness readiness board over v0.1.44. Existing installs are offered it by the in-plugin update check.

macOS — Apple Silicon beta v0.1.45-beta.3

Developer ID signed, notarized by Apple, and stapled. The macOS installer is built and notarized separately from the Windows release, so its version can trail Windows; it carries the same raw-media recovery, waiting-room and video-quality fixes and the panelist loudness readiness board.

Download macOS installer (.pkg) SHA-256 checksum macOS release notes

Requires an Apple Silicon Mac (M1 or later). The package is built against OBS Studio 32.2.1; use that version or newer for this beta. Intel Macs are not supported by this package.

Close OBS, then open the downloaded .pkg.
Install for your user account. No administrator password is needed.
Reopen OBS, sign in to Zoom through CoreVideo, and join a meeting. Allow the requested permissions; the host must grant recording permission for media capture.

For ISO recording, set a working FFmpeg executable in Zoom ISO Recorder and test it before recording. The macOS package does not bundle FFmpeg.

Talkback is Windows-only. For your own screen, use OBS's macOS Screen Capture source; CoreVideo receives other participants' shares.

To verify the download, save the installer and checksum in the same folder and run:

shasum -a 256 -c CoreVideo-Setup-v0.1.45-beta.3.pkg.sha256

Windows requirements

OBS Studio 30 or newer, 64-bit.
Windows 10 or Windows 11 (x64). For macOS, use the Apple Silicon beta installer above. Linux requires a source build.
A Zoom account you can sign in with. CoreVideo joins meetings through the Zoom Meeting SDK, so the video quality and number of simultaneous feeds you get follow your Zoom account entitlements.
Downstream bandwidth for the feeds you subscribe to — roughly 4-6 Mbps per 1080p participant. Standard accounts are typically capped around 30 Mbps incoming; Enhanced Media / HBM raises that to roughly 100 Mbps.

Install on Windows

Close OBS Studio.
Run the installer and point it at your OBS installation directory if it is not detected automatically.
Start OBS and open Tools -> Zoom Plugin Settings to sign in, then Docks -> Zoom Control to join a meeting.
Add a CoreVideo Participant source to any scene, then assign it to a participant, the active speaker, a spotlight slot, or the screen share.

The Windows installer is not code-signed yet, so Windows SmartScreen warns the first time you run it — "More info", then "Run anyway". Verify the SHA-256 below if you would rather check the file than trust the dialog.

The Core Plugin Guide walks through participant routing, isolated audio, and ISO recording in detail, and Support covers log collection and reporting a bug.

Verify your download

Each release ships a SHA-256 file alongside the binary. On Windows, compare the hashes with PowerShell:

Get-FileHash .\CoreVideo-Setup-v0.1.45.exe -Algorithm SHA256

Building from source

CoreVideo is MIT-licensed and builds from source on Windows, macOS, and Linux. See the repository for the toolchain requirements and CMake options, including hardware-accelerated colour conversion.
