Few important releases related to OBS Spout and OBS NDI that you may need to update if you have recently upgraded to OBS 28.x
Spout2 Plugin for OBS Studio (64bit)
This plugin enables the import and export of shared textures at high resolution to and from SPOUT2 compatible programs.
Download Latest version : https://github.com/Off-World-Live/obs-spout2-plugin/releases/tag/v1.6-beta
Previously the only way to import shared textures from SPOUT was via the DirectShow SpoutCam interface or by screen-capturing the full-screen output of the SpoutReceiver program.
The SpoutCam is limited to standard webcam resolutions and capped at 1920x1080 and capturing the SpoutReceiver is both inefficient and limited by your current screen resolution.
Previously, there was no way of outputting Spout video textures from OBS.
This plugin implements the SPOUT2 SDK, creates an OBS Source from the SPOUT shared texture and a Spout output which sends the content of the OBS canvas to Spout.

OBS NDI plugin
