# Raspberry Pi Roamer Camera
This project was an attempt to create a camera that we could strap to actors, and broadcast it over the internal network.

- [Streaming Audio](#streaming-audio)

## Streaming Video
For streaming video, I went with a generic install of [UV4L](https://www.linux-projects.org/uv4l/), with [this config file](.repo/configs/uv4l-raspicam.conf)
Here were the exact camera settings we used for our application:
We could then access our stream using this URL:
```http
http://IP OF PI:8080/stream/video.mjpeg
```
## Streaming Audio
Now for the audio streaming: I could not find a better way to do this, and the video and audio were not sync'd. We did not continue this project enough to inject time code.
I ended up using VLC media player:
```bash
cvlc -vvv alsa://plughw:2 --sout '#transcode{acodec=mp3,ab=64,channels=1}:standard{access=http,dst=0.0.0.0:8888/out.mp3}' --sout-mux-caching 100 --network-caching 100
```
Then, we can access our MP3 stream via OBS or VLC:
```http
http://IP OF PI:8888/out.mp3
```
## Monitoring the Pi
[This is a NodeJS application](./CameraServer/) I wrote to be able to monitor the PI. You can access the JSON for this page at:
```http

```
```json

```
Error messages:
* Under-voltage!
* ARM frequency capped!
* Currently throttled!
* Soft temperature limit active.
* Under-voltage has occurred since last reboot.
* Throttling has occurred since last reboot.
* ARM frequency capped has occurred since last reboot.
* Soft temperature limit has occurred.
I wrote a simpleish HTML page to display these stats. You can find it [here](./monitor/index.html)
## Startup Script
I created a small startup script that is executed when the PI boots up. You can find it [here](./.repo/scripts/startup-script.sh)
