# Wild Dragon Playout sidecar — CasparCG Server + Node AMCP control shim.
#
# NDI + DeckLink SDKs are NOT redistributable. They are fetched at build time
# from URLs supplied as build args; the build still succeeds without them.

# CasparCG 2.4.0 ubuntu22 zip — last release with a generic x86-64 tarball.
# 2.4.1+ and 2.5.x ship as .deb compiled with AVX2 which crash on Sandy Bridge
# (AVX only, no AVX2). The ubuntu22 zip ships its own bundled libs under lib/.
