# Capture-card SDK / driver file store

This directory holds the **proprietary, non-redistributable** vendor SDKs and
drivers used to enable SDI / NDI capture cards on cluster nodes.

> **INTERNAL ONLY.** These files are licensed by their respective vendors and
> must **not** be published, redistributed, or committed to any public mirror.
> This repository is private. Do not change that.

## Why these live in the repo

The cluster admin screen lets an operator install/update capture-card drivers on
a node from the web UI (no SSH). The node-agent spawns a one-shot privileged
container that bind-mounts this repository and runs
[`deploy/install-driver.sh <vendor>`](../deploy/install-driver.sh), which reads
the vendor files from `sdk/<vendor>/`. Because the install must work offline on
an isolated broadcast LAN, the binaries ship in-repo rather than being fetched at
install time.

## Layout

```
sdk/
  README.md            ← this file
  blackmagic/          ← Blackmagic Desktop Video (DeckLink) .deb
  aja/                 ← AJA ntv2 driver source / installer
  deltacast/           ← Deltacast VideoMaster installer
  ndi/                 ← NDI redistributable runtime libs
```

Each vendor directory has its own `README.md` listing **exactly** which files an
admin must drop in. A `.gitkeep` keeps the empty directory committed.

## Important

- **No binaries are committed by default.** The directory structure + READMEs
  are the deliverable. An admin downloads the proprietary files from the vendor
  (per their licence) and drops them in the matching `sdk/<vendor>/` directory.
- The install script **fails gracefully** with a clear message if the expected
  file is absent — it never fabricates or downloads binaries.
- Target host OS for all install paths is **Ubuntu 22.04 LTS (jammy), x86_64**,
  matching the cluster worker nodes.
