# ── Stage 2: Build FFmpeg with DeckLink + NVENC (HEVC/H264) support ─────────
# All-Intra HEVC NVENC is the master codec for growing-file ingest (see
# docs/design/2026-05-29-all-intra-hevc-ingest.md).  This stage gets the
# nv-codec-headers (header-only, no driver / no full CUDA toolkit needed)
# so ffmpeg's configure can light up hevc_nvenc / h264_nvenc / cuvid.
# At runtime, /dev/nvidia* + the host driver libs (via the NVIDIA Container
# Toolkit) supply the actual encoder.

# ── Stage 1b: Build bmx (raw2bmx / bmxtranswrap) from source ─────────────────
# bmx (bmxlib + libMXF + libMXF++) is the reference GROWING OP1a MXF writer. It
# writes a fresh IndexTableSegment (with an updated IndexDuration) into a new
# body partition at a periodic interval, so the recorded duration is readable —
# and INCREASES — from the header+index alone while the file is still being
# written (no footer needed). This is what makes the master a TRUE Premiere
# growing file. ffmpeg's MXF muxer cannot do this (its real duration/index lands
# only in the footer at av_write_trailer, so duration probes N/A until close).
#
# Debian/Ubuntu have no `bmxlib-tools` package (verified absent in bookworm), so
# we build from the BBC source. liburiparser/uuid/lzma/zlib/expat are the build
# deps; the runtime needs only libexpat1 + liburiparser1 + libuuid1 (added in
# the runtime stage below). Pinned to the bbc/bmx default branch (v1.6.x).
