Dockerfile is now a two-stage build that compiles FFmpeg from source with --enable-decklink against the Blackmagic SDK 16.x headers in services/capture/sdk/ (operator-supplied, gitignored). build-with-decklink.sh + patch_decklink.py drive the build. docker-compose.yml mounts /dev/shm, /run/dbus, /run/systemd into mam-api, capture, web-ui so the BMD runtime can talk to the host. capture-manager.js wraps SDI sources with -vf yadif=mode=1 (deinterlace). recorders.html defaults to SDI source type now that we have a working DeckLink path.
