First 2.5 build got past the deb install but the binary-discovery step produced an empty $BIN (test -n failed): the 2.5 deb names its executable casparcg-server-2.5, which the old case pattern (*/casparcg, */CasparCG Server) didn't match. Broaden the match to /usr/bin/*casparcg*server*, fall back to the known /usr/bin/casparcg-server-2.5, symlink it to /usr/local/bin/casparcg, and make /opt/casparcg a real dir for our config (no longer symlinked onto /usr/bin). Entrypoint launches `casparcg <config>` from PATH instead of ./casparcg in a cwd. Still NOT runtime-validated: 2.5 may reject the 2.3-era casparcg.config schema (a bad config shows up as "Configuration file --version was not found"); the deb ships a reference config at /usr/share/casparcg-server-2.5/casparcg.config to diff against at smoke time.

# Wild Dragon Playout sidecar — CasparCG Server + Node AMCP control shim.
|
|
#
|
|
# CasparCG's mixer needs an OpenGL context. On a node with a real GPU we'd pass
|
|
# the device + driver through; for the headless / no-GPU case we run a virtual
|
|
# framebuffer (Xvfb) so the GL context initialises. The container is launched
|
|
# --privileged by mam-api (same as capture) so DeckLink / NDI hardware is
|
|
# reachable when present.
|
|
#
|
|
# NDI + DeckLink SDKs are NOT redistributable. They are fetched at build time
|
|
# from URLs supplied as build args (mirror them into your own artifact store);
|
|
# the build still succeeds without them (NDI/DeckLink consumers simply won't be
|
|
# available — SRT/RTMP/test output still work).
|
|
|
|
# CasparCG 2.5.0 ships Linux builds as Ubuntu .deb packages (noble = 24.04), not
|
|
# a portable tarball, so the base is ubuntu:24.04 and Node is added on top. The
|
|
# server deb pulls its own GL/ffmpeg/openal runtime deps via apt; we add Xvfb +
|
|
# mesa SW-GL drivers for the headless GL context.
