obs-ndi - NewTek NDI™ integration into OBS Studio 4.5.2

Only use this release with OBS 22 or above!

Changes since 4.5.1
  • Source: remove the "Default" value for the YUV range and colorspace fields. Default values for these fields are now Partial range with BT.709 colorspace
  • Source: the "Source name" field is now an Editable Combo field (current value can be selected from the list of available NDI sources as usual, or typed manually). This prevents the currently selected source name from disappearing from the list whenever the source becomes unavailable.
  • Preview Output: use the same YUV settings as the Main Output
  • Bugfix: Qt version mismatch on macOS
  • Preview Output Improvement: fix handling of scene preview change events to properly keep track of the current preview scene
Windows, Linux and macOS Install instructions: see the release page on GitHub.

Changes since 4.1.3
  • macOS releases now use the NDI runtime installed from the redistributable.
