# Deltacast VideoMaster driver / SDK
Drop the **Deltacast VideoMaster** Linux installer into this directory.
## Required file
| File | Notes |
|------|-------|
| `VideoMaster*.run` **or** `VideoMaster*linux*.tar.gz` | The VideoMaster SDK + driver installer for Linux. Contains the `videomasterhd` kernel module sources and the `install.sh` driver installer. |
Example names: `VideoMaster-6.25.0.run`, `VideoMaster_6_25_Linux.tar.gz`
The installer reads the **newest** matching file.
## Where to get it
Deltacast → Products → *SDK* (<https://www.deltacast.tv/products/sdk>). Request
the VideoMaster Linux package (licence-gated) and copy the `.run` self-extractor
or the `.tar.gz` here unmodified.
## What the install script does
1. Ensures `linux-headers-$(uname -r)`, `build-essential`, `dkms` are present.
2. Runs the vendor installer:
- `.run` → executed with `--noexec --target <dir>` then its `install.sh`,
- `.tar.gz` → extracted, then its bundled `install.sh` is run.
3. Loads the Deltacast module (`modprobe videomasterhd` / vendor load script).
4. Verifies a `/dev/deltacast*` device node appears.
A **reboot may be required** after a first-time VideoMaster install (udev rules
+ firmware). The script reports this explicitly.
