obs-ndi - NewTek NDI™ integration into OBS Studio 4.10

This release is for OBS 28.0.0 or above. It is not a feature release, it simply provides updated binaries to support the changes made in OBS 28

The Ubuntu binaries are for OBS 28, but are compiled for Qt5 on Ubuntu 20.04. Binaries for 22.04 and Qt6 are not currently available.

The macOS binaries are for OBS 28 and Qt6, but you will likely not be able to use this version on ARM machines due to libndi 4 not providing support for ARM.

Windows​

• Using the installer (recommended) : download it, launch it and follow the instructions.
• Using the obs-ndi-4.10.0-Qt6-Windows.ziparchive:
  1. Copy the contents of the archive to the root of your OBS Studio installation folder
  2. Install the NDI 4.5 Windows runtime using the installer provided here: https://ndi.palakis.fr/runtime/ndi-runtime-4.5.1-Windows.exe

On Windows, you must reboot your computer to make a new or updated NDI Runtime installation effective

Ubuntu/Debian (Qt5)​

Download libndi4_4.5.1-1_amd64.deb and obs-ndi-4.10.0-Ubuntu64.deb (both are provided below), and install them on your system.

macOS​

1. Download and run obs-ndi-4.10.0-Qt6-macOS.pkg (provided below)
2. Install the NDI 4.5.1 macOS runtime using the installer provided here: https://ndi.palakis.fr/runtime/ndi-runtime-4.5.1-macOS.pkg

(P.S. Thanks to @DDRBoxman for the binaries here and getting us by for the time being while 5.x is in development!)

Windows, Linux and macOS Install instructions: see the release page on GitHub.

This release fixes an issue targeting the Debian/Ubuntu package. For the latest Windows and macOS release, see obs-ndi 4.9.0.

Only use this release with OBS Studio v25 or above!

Changes since 4.9.0

• Ubuntu Bugfix: plugin installed in the wrong location (is supposed to be in /usr/lib/obs-plugins instead of /usr/lib/$multiarch/obs-plugins)

Windows, Linux and macOS Install instructions: see the release page on GitHub.

Only use this release with OBS Studio v25 or above!

Changes since 4.8.0

• Improvements to the NDI Source (#459):
  • The "Sync" setting now defaults to "Source Timing"
    • This is the best option to keep audio and video synced together, and it has been tested against OBS and vMix with successful results.
  • Among the options of the "Sync" source parameter, the "Internal" sync option has been removed
    • This mode never actually worked and is fundamentally flawed.
• All platforms now target OBS v25 or above (including you, macOS users!)
• Feature: Russian translation (#443)
• Bugfix: the Ubuntu/Debian package now only installs the plugin into /usr/lib/x86_64-linux-gnu/obs-plugins (#460)

Windows, Linux and macOS Install instructions: see the release page on GitHub.

Only use this release with OBS Studio v25 (v24 on macOS) or above!

Changes since 4.7.1

Features & Improvements

• NDI 4.5 support (#416)
  • On macOS, you need to install the NDI 4.5 runtime manually! (runtime download links are provided on the Download page linked below)
• Spanish localization (thanks @COOLIGUAY in #357)

Bug fixes

• Bugfix: The NDI Output Settings dialog wasn't always showing text input fields for the Program & Preview output names (#373)
• Bugfix: NDI runtime download issues on Windows. The obs-ndi installer now downloads the runtime from a mirror I manage to prevent download errors that cause failed installs (#140)
• A myriad of macOS bugfixes:
  • The plugin wasn't loading because of a problem with how macOS looks for plugin dependencies (#409)
  • With NDI 4.5 installed on the system, obs-ndi 4.7.1 would crash. This is now fixed with the addition of NDI 4.5 support.
  • The obs-ndi installer could fail to download the NDI runtime because of download server issues, or could fail to install it because it is not digitally signed. This step has been removed. macOS users now have to download & install the NDI 4.5 runtime separately (links provided on the Download page).
  • In addition to being digitally signed, the obs-ndi installer is now also notarized by Apple. This should eliminate "malicious software" errors on Catalina.

Windows, Linux and macOS Install instructions: see the release page on GitHub.

Only use this release with OBS 22 or above!

Changes since 4.7.0

• Windows installer: the NDI runtime installation is now a separate component that can be disabled if you don't want the runtime automatically installed
• macOS: fixes for OBS Studio 24.0.3 and Catalina compatibility

Windows, Linux and macOS Install instructions: see the release page on GitHub.

Only use this release with OBS 22 or above!

Changes since 4.6.2

• Plugin updated to NDI 4.0. Fixes an issue where previous versions of the plugin were not compatible with the NDI 4.0 Runtime. If the installer doesn't do it for you (on Windows & macOS), download the NDI Runtime using the link in the install instructions, then reinstall it and reboot. Linux users must install the new libndi manually.

Windows, Linux and macOS Install instructions: see the release page on GitHub.

Changes since 4.5.3

• Fix for microstutter issues encountered by several users (courtesy of @loopy750)
• Bugfix: the Dedicated Output filter used to output nothing if a Color Correction filter was placed on first position of a filter chain
• Source: new "Latency" option.
  • Be careful: setting this to "Low" can cause microstutters. Use with caution!
• Source and Output: native support for NV12 and I420 YUV pixel formats.
  • Previous versions of the plugin used to perform the conversion to NDI's native UYVY format, but now the NDI SDK supports these two formats natively, removing the need for any conversion performed by the plugin.
• Linux + macOS bugfix: NDI Name text inputs for program and output were not visible
• macOS enhancement: try to prevent App Nap from suspending background tasks
• NDI SDK support updated to version 3.8
• Catalan localization
• NDI runtime version now shown at the bottom of the settings dialog (and printed in the current log)
