## How to use Octoprint with an IP camera that has an RTSP stream available

#### Optional: For Wyze cam only 

Install [Dafang Hacks](https://github.com/EliasKotlyar/Xiaomi-Dafang-Hacks) on the Wyze Cam.

Once running and all is functional, continue.
Set video bitrate to 1500, VBR, 30fps.

### Installation

If OctoPrint is running on a Raspberry Pi (3B minimum):
  
```
ssh pi@<raspberry_ip>
sudo apt update
sudo apt install vlc
```

VLC will be used to transcode the rtsp stream to a http stream which OctoPrint can use as streaming URL

```
nano http_stream.sh
```
paste the following line:

```
cvlc -I dummy rtsp://ip_of_yourcam --sout "#transcode{vcodec=mjpg,quality=3,fps=5,acodec=none,width=1280,height=720}:standard{access=http{mime=multipart/x-mixed-replace; boundary=7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=:8888/videostream.cgi}" 2>/dev/null
```

Change the ip_of_yourcam to match the full rtsp url from your camera

CTRL+x to save

```
chmod +x http_stream.sh
./http_stream.sh
```

Now you should be able to open your browser: 

`http://<raspberryip>:8888/videostream.cgi`

If it works, you can use this url in OctoPrint for the `Stream URL`

For the snapshot URL use the stills url from your camera

Change your user/pass and ip to match your setup
Click `advanced options` and **uncheck** `Validate SSL on snapshot URL (if applicable)`

As this process is cpu intensive you will need to play around with the `quality=x,fps=x`  (fps = frames per second) options in the cvlc command. These settings work for me, but as I wanted better quality I have this process running on a more powerful device.
