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)
