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.

The image never built: CASPAR_URL pointed at a v2.3.3-stable Linux tarball
that CasparCG never published (2.3.x is Windows-only; Linux builds start at
2.4.0, and 2.4.1+ ship only as .deb). Rewrite to install the 2.5.0 noble
server + CEF debs on an ubuntu:24.04 base (Node 20 via nodesource), letting
apt resolve the GL/ffmpeg/openal runtime deps. Binary install dir is
discovered from the deb file list and symlinked to /opt/casparcg so the
entrypoint + config still run from there. Move CasparCG log/data dirs to
/media (writable mount) since the install dir may be read-only.
NOT runtime-validated: the 2.5 casparcg.config schema and the AMCP consumer
syntax (ADD <ch> STREAM/FILE) were authored against 2.3 and must be smoke-
tested against 2.5 before a channel start can be trusted.

Post-review fixes for the 8-commit playout-mcr drop:
- Scheduler self-calls (callSelf -> /recorders, /playout) carried no auth, so
under AUTH_ENABLED=true requireUiHeader 403'd every mutating POST. This broke
playout failover AND scheduled recordings. Add a per-boot in-process service
token (x-internal-token) the scheduler attaches; requireAuth/requireUiHeader
treat it as the seeded admin. No env/compose config needed.
- Failover deadlocked: restartChannel set status='starting' then the scheduler
called the guarded /start route, which 409s on 'starting'. Extract the spawn
body into spawnChannelSidecar() shared by /start and restartChannel; failover
now spawns directly with no self-call.
- Phase A playlist stalled after 2 clips: _scheduleAdvance cued the next clip
via LOADBG AUTO but never advanced the pointer. Pass asset_duration_ms in the
/play payload and arm a duration-based timer that advances currentIndex and
cues subsequent clips, keeping as-run in sync for arbitrary-length playlists.
- CasparCG consumer syntax was invalid: "ADD <ch> FFMPEG" is the producer name,
not a consumer keyword, and old -vcodec/-acodec short args are rejected. Use
STREAM/FILE with -codec:v / -codec:a / -preset:v / -tune:v and a format=yuv420p
filter ahead of libx264 (channel output is RGBA).

One container per channel. Built like capture/build-with-decklink: NDI +
DeckLink SDKs fetched at build, runs --privileged with Xvfb for the GL
context where no real display is present.
Components:
- entrypoint.sh: Xvfb + CasparCG launch, creates /media/live/<CHANNEL_ID>
- src/amcp.js: TCP AMCP client
- src/playout-manager.js: channel lifecycle, playlist walk via LOADBG AUTO
for gapless transitions; primary consumer (decklink/ndi/srt/rtmp) plus a
second FFMPEG HLS consumer (~600 kbps, 2s segments) for the UI preview
- src/index.js: HTTP shim — /channel/start, /playlist/load, transport
- frame-rate helper picks fps from video_format (59.94 → 60000/1001) so
SEEK / LENGTH frame math is correct
