AV-Playout — Install requirements
=================================

Needed on each PC:

  Node.js        required   — runs AV-Playout
  ffmpeg         recommended — video thumbnails
  NDI Runtime 6  required   — CasparCG 2.5 needs this DLL even if NDI output is OFF
  CasparCG       required   — install separately


Easiest
-------
1. Double-click:  Install Requirements.bat
   (downloads Node.js + ffmpeg + NDI Runtime — no winget needed)
2. Double-click:  START.bat
3. Setup → Caspar folder → Save & Launch


If Caspar quits immediately with code 3221225781 / 0xC0000135
-------------------------------------------------------------
That means Processing.NDI.Lib.x64.dll is missing.

Fix:
  - Run Install Requirements.bat again, OR
  - Install “NDI Runtime” from https://ndi.video/tools/
  - Or download: https://downloads.ndi.tv/SDK/NDI_SDK/NDI%206%20Runtime.exe
  - Then Launch Caspar again

AV-Playout will also try to download NDI Runtime automatically the first time
you click Save & Launch if the DLL is missing.


PowerShell (manual)
-------------------
  powershell -NoProfile -ExecutionPolicy Bypass -File .\tools\install-requirements.ps1
