Root cause: MXF OP1a writes its index/duration only in the footer partition
on finalize, so a growing MXF has no footer and VLC/Premiere/ffmpeg-strict
refuse it ("Unable to open file on disk"). Separately the proxy job pointed
at a .mov S3 key that never existed (promotion worker watched a local empty
disk, not the SMB share), so stop -> instant proxy failure.
Fix: growing master is now MPEG-TS (H.264 high422 all-intra + AAC), which is
readable from the first PAT/PMT while still growing (verified mid-write decode).
hiresKey derives from the actual produced extension. Capture skips finalize for
growing recorders (leaves asset live for promotion). Promotion worker CIFS-
mounts the same growing_smb share before scanning; worker image gets cifs-utils
and worker-p4 runs privileged (local /growing bind removed). /live-path uses .ts.

# GPU-accelerated worker — requires NVIDIA Container Toolkit on the host
|
|
# Build: docker compose -f docker-compose.yml -f docker-compose.gpu.yml build worker
|
|
#
|
|
# Prerequisites:
|
|
# - NVIDIA drivers installed on host
|
|
# - NVIDIA Container Toolkit: https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/
|
|
# - GPU capability in docker-compose.gpu.yml enables NVENC access
|
|
|

FROM nvcr.io/nvidia/cuda:12.3.1-base-ubuntu22.04

|
|
# Install Node.js 20, ffmpeg (Ubuntu's ffmpeg includes h264_nvenc/hevc_nvenc),
|
|
# and yt-dlp for the YouTube importer.
|
|
#
|
|
# yt-dlp is NOT installed from apt: Ubuntu 22.04's package is pinned to a 2022
|
|
# release, which YouTube has long since broken (extraction fails). yt-dlp must
|
|
# track YouTube's frequent changes, so we pull the latest self-contained
|
|
# release binary at build time. /usr/local/bin precedes /usr/bin on PATH, so
|
|
# `yt-dlp` resolves to this one. Rebuild the worker image to refresh it.
|
|
# cifs-utils: the promotion scanner mounts the growing-files SMB landing zone
|
|
# at /growing so it watches the SAME share the capture sidecars write to.
