# Python-CamIO
A library to handle multiple cameras with opencv, based on threading and callbacks.
## Single Camera
You could use a single camera with callbacks to do some image/video processing:
```python
from camio import Camera
def proccesVideo(frame):
print(frame.shape)
# Do some video processing
# Or displays the frame
# .
# .
# Instance a camera object
camera = Camera(src=0, fps=10)
# Setup callbacks
camera.on('frame-ready', proccesVideo)
# Start read loop in another thread
camera.start()
```
## Multiple Cameras
Also, camIO can manage multiple cameras at the same time:
```python
from camio import Cameras
def frameAvailable(device):
"""Multiple cameras manager callback."""
print(f"{device} has a new frame available")
# Create a list of cameras with their corresponding sources
camerasAdmin = Cameras(devices={
'camera1': 0,
'camera2': 1
}, fps=5, reconnectDelay=5)
# Setup Callbacks
camerasAdmin.on('frame-available', frameAvailable)
# Starts all read loops for cameras in differents threads
camerasAdmin.startAll()
```
And here are some extra functions for manage multiple cameras:
```python
from camio import Cameras
camerasAdmin = Cameras(devices={
# 'deviceName': src
'camera1': 0,
'camera2': 1
}, fps=5, reconnectDelay=5)
# Start all devices at once on separate threads
camerasAdmin.startAll()
...
# Start one single device on a separate thread
camerasAdmin.startOnly('camera1')
# After of starting all devices you can do other tasks
my_tasks()
...
# get a frame of a specific device
frame = camerasAdmin.getFrameOf('camera1')
...
# Get a list of all frames
frames = camerasAdmin.getAllFrames()
...
# Pause All devices
camerasAdmin.pauseAll()
...
# Resume All devices
camerasAdmin.resumeAll()
...
# Pause one specific device
camerasAdmin.pauseOnly('camera1')
# Resume one specific device
camerasAdmin.resumeOnly('camera1')
...
# Update all FPS(s) speed
camerasAdmin.setSpeed(fps=12)
# Update one specific FPS speed
camerasAdmin.setSpeedOnly('camera1', fps=5)
```
