# NDI redistributable runtime

Drop the **NDI runtime redistributable** shared libraries into this directory.
NDI has **no kernel module** — it is purely user-space shared libraries, so this
is the lowest-risk install (no DKMS, no reboot).

## Required files

| File | Notes |
|------|-------|
| `libndi.so.*` | The versioned NDI runtime shared object, e.g. `libndi.so.6`. **Required.** |
| `libndi.so` *(optional)* | Dev symlink. The installer recreates it if absent. |

You may instead drop the whole **NDI SDK / Advanced SDK** `lib/x86_64-linux-gnu/`
directory contents here; the installer copies every `libndi*.so*` it finds.

Example name: `libndi.so.6.1.1`

## Where to get it

NDI → Tools / SDK download (NDI 6 SDK or NDI Advanced SDK for Linux). The
runtime libs live under `lib/x86_64-linux-gnu/` in the SDK. Per the NDI licence
the runtime is redistributable **within your own product** only — keep it in this
private repo, do not publish it.

## What the install script does

1. Copies every `libndi*.so*` from here into `/opt/ndi-lib`.
2. Writes `/etc/ld.so.conf.d/ndi.conf` pointing at `/opt/ndi-lib` and runs
   `ldconfig`.
3. Recreates the `libndi.so` → `libndi.so.<N>` dev symlink if missing.
4. Verifies `ldconfig -p | grep libndi` resolves.

**No reboot required.** Running processes that already loaded an old `libndi`
must be restarted to pick up the new version — the script notes this.
