FAQ

• Using ultragrid, I want to send a Spout stream, but the receiver only gets a black texture.
  • Check the local Spout settings. The local machine needs to be able to share textures via GPU (a dedicated GFX-Card). In some instances it was enough to simply open the spout settings (located at C:\Program Files\SPOUT-2007\SPOUTSETTINGS) and confirm with 'OK'
• I am sending a stream, and one machine receives the stream and the other is not.
  • Check the firewall. Both Windows and OSX will request a confirmation if a network connection is started (usually only once for each channels).
    • Windows: Settings > Update & Security > Windows Security > Firewall and Network protection > Allow an app through the firewall
      • look for 'NatNetThree2OSC' and 'uv_tb0' .. 'uv_tb9'
    • OSX: System preferences > Security & Privacy > Firewall > Firewall Options
      • look for 'uv-qt'
• Sending also audio from an NDI stream via Ultragrid degrades the video quality
  • Route the audio via Blackhole
