- `-s --source`: the ssh destination of the reMarkable (default: `root@10.11.99.1`)
- `-o --output`: path of the output where the video should be recorded, as understood by `ffmpeg`; if this is `-`, the video is displayed in a new window and not recorded anywhere (default: `-`)
- `-f --format`: when recording to an output, this option is used to force the encoding format; if this is `-`, `ffmpeg`’s auto format detection based on the file extension is used (default: `-`).
- `-w --webcam`: record to a video4linux2 web cam device. By default the first found web cam is taken, this can be overwritten with `-o`. The video is scaled to 1280x720 to ensure compatibility with MS Teams, Skype for business and other programs which need this specific format. See [video4linux loopback](#video4linux-loopback) for installation instructions.

- `-m --measure`: use `pv` to measure how much data throughput you have (good to experiment with parameters to speed up the pipeline)
- `-t --title`: set a custom window title for the video stream. The default title is "reStream". This option is disabled when using `-o --output`
- `-u --unsecure-connection`: send framebuffer data over an unencrypted TCP-connection, resulting in more fps and less load on the reMarkable. See [Netcat](#netcat) for installation instructions.

The result should contain a line with "platform:v4l2loopback".
### Netcat
To use an unsafe and faster connection, we need the command `nc`, abbreviation of `netcat`.
If your system does not provide `nc`, the output of `command -v nc` is empty. In this case you need to install it.
[Several implementations](https://wiki.archlinux.org/index.php/Network_tools#Netcat) of `netcat` exists. On Ubuntu, you can install the version developed by OpenBSD, which is light and supports IPv6:
```
apt install netcat-openbsd
