# AJA NTV2 driver
|
||
|
|
|
||
|
|
Drop the **AJA NTV2** driver source/SDK archive for Linux into this directory.
|
||
|
|
|
||
|
|
## Required file
|
||
|
|
|

|
| File | Notes |
|
||
|
|
|------|-------|
|
||
|
|
| `ntv2sdk*linux*.zip` **or** `libajantv2*.tar.gz` | The NTV2 SDK / open-source `libajantv2` source tree containing `driver/linux/` with the kernel-module `Makefile` and `load_ajantv2` / `unload_ajantv2` scripts. |
|
||
|
|
|
||
|
|
Example names: `ntv2sdklinux_17.0.1.zip`, `libajantv2-17.0.1.tar.gz`
|
||
|
|
|
||
|
|
The installer reads the **newest** matching archive.
|
||
|
|
|
||
|
|
## Where to get it
|
||
|
|
|
||
|
|
AJA → Support → Software & firmware → *NTV2 SDK* (Linux), or the public
|
||
|
|
`aja-video/libajantv2` source release. Download the Linux SDK zip / source
|
||
|
|
tarball and copy it here unmodified.
|
||
|
|
|
||
|
|
## What the install script does
|
||
|
|
|
||
|
|
1. Ensures `linux-headers-$(uname -r)`, `build-essential` are present.
|
||
|
|
2. Extracts the archive into a scratch build dir.
|
||
|
|
3. Builds the `ajantv2` kernel module from `driver/linux` (`make`).
|
||
|
|
4. Installs the module under `/lib/modules/$(uname -r)/extra`, runs `depmod`,
|
||
|
|
`modprobe ajantv2` (falls back to the SDK's `load_ajantv2` script).
|
||
|
|
5. Verifies the `ajantv2` module is loaded.
|
||
|
|
|
||
|
|
A **reboot is not normally required**; the module loads immediately after build.
|
||
|
|
The script reports if a reboot is needed (e.g. an old in-tree module is wedged).
