omniview 1.2.0

Receiving video stream from multiple cameras (usb/ip) for further processing

---

📝 About the project

A system for simultaneous viewing and processing of streams from multiple cameras (USB/IP) with the ability to integrate into computer vision.

🚀 Features

• Support for USB and IP cameras (via RTSP)
• Automatic reconnection in case of connection failure
• Customizable camera parameters (resolution, FPS)
• Multithreaded frame processing
• Flexible callback system for video processing
• Ready-to-use GUI for viewing streams
• Configuration via constructor parameters

⚙️ Installation

pip install omniview

🛠️ Usage

🔌 Basic example for USB cameras

from omniview.managers import USBCameraManager


def frame_callback(camera_id, frame):
    # Your framing
    pass


if __name__ == "__main__":
    manager = USBCameraManager(
        show_gui=True,
        show_camera_id=True,
        frame_callback=frame_callback
    )
    try:
        manager.start()
    except KeyboardInterrupt:
        manager.stop()

🌐 Basic example for IP cameras

from omniview.managers import IPCameraManager


def frame_callback(camera_id, frame):
    # Your framing
    pass


if __name__ == "__main__":
    manager = IPCameraManager(
        show_gui=True,
        rtsp_urls=[
            "rtsp://admin:12345@192.168.0.1:9090",
        ],
        frame_callback=frame_callback
    )
    try:
        manager.start()
    except KeyboardInterrupt:
        manager.stop()
