# Setting up your Pi camera for Mainsail

Follow this tutorial, but instead, use the codes below when needed: <https://3dp.tumbleweedlabs.com/firmware/klipper-firmware/adding-webcam-support-to-mainsail>

### Testing the Stream

Then start mjpg-streamer using your Raspberry Pi camera:

```bash
/usr/local/bin/mjpg_streamer -i "input_raspicam.so -fps 15 -x 1640 -y 922" \
 -o "output_http.so -w /usr/local/share/mjpg-streamer/www"
```

## ...

## Run MJPG Streamer on Startup

This will open nano editor. Paste the following into the editor:

```bash
#!/bin/sh
# /etc/init.d/mainsail-stream.sh
### BEGIN INIT INFO
# Provides:          mainsail-stream.sh

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://lazarofilm.gitbook.io/3d-printing/setting-up-your-pi-camera-for-mainsail.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
