On Windows you need also [Chocolatey](https://chocolatey.org/install).
# Linux Users
Before building the streamer, those on Linux would have to build and install [`FFmpeg/nv-codec-headers`](https://github.com/FFmpeg/nv-codec-headers). The nv-codec-headers for nvidia users requires at least driver version `520.56.06` to work properly, taken from nv-codec-header's README.
Run the following commands as shown:
```bash
git clone https://github.com/FFmpeg/nv-codec-headers.git
cd nv-codec-headers/
sudo make install
```
# Streamer Building
First you need to gather some additional resources in preparation for the build.
