A simple utility tool to list cameras connected in a consistent way across different platforms (linux or MacOS).
When running on MacOS it will leverage AVFoundation, and make calls leveraging pyobjc bindings. No additional dependencies are required.
On linux, it will use v4l2-ctl to list cameras. Make sure you have v4l-utils installed. ie.:
sudo apt-get install v4l-utilsfrom camera_enumerator import get_cameras, Camera
cameras: list[Camera] = get_cameras()
for cam in cameras:
print(f"- Camera {cam.index}: {cam.name}")
for format in cam.formats:
print(" %dx%d @ %d fps" % format)Output:
- Camera 0: FaceTime HD Camera
1280x720 @ 30 fps
640x480 @ 30 fps
