Raspberry Pi API project that provides two video streaming options and stepper motor movement 360° rotation.
Full Youtube video: Raspberry pi camera gimbal
The main API endpoints for this projects are for camera movement and video stream
/api/stepper with query params
- move = up
- move = down
- move = right
- move = down
- move = stop
/stream.mjpg
This endpoint is used for video streaming.
But we also have another option for video streaming that is more faster/better video quality
In stream_server (https://github.com/ManolescuSebastian/Raspberry-Camera-Gimbal/tree/master/CameraGimbal/stream_server) we have the a standalone server that requires to run on a different port.
More information here: https://picamera.readthedocs.io/en/release-1.10/recipes1.html
In order to start the server first we need to add a base URL in MainApp.py (or CameraStream.py if you are using the streaming server).
To find out your Raspberry Pi IP open a terminal and type ifconfig (192.168.1.X)
Add rapspberry IP to MainApp.py in the last code line (e.q. app.run(debug=True, port=5050, host='192.168.1. todo',threaded=True)) or/and if you are using CameraStream.py add it to address = ('192.168.1.todo', 5020)
Note: You can add any port you want (5050, 5020) was a personal choice.
After the steps above are completed open a terminal and type
python MainApp.py or/and python CameraStream.py
