Setting up your Pi camera for Mainsail

There is a great tutorial on how to do that already but there is a couple of errors in the code. Here are the correct snippets to use for Pi Camera.
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:
/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:
#!/bin/sh
# /etc/init.d/mainsail-stream.sh
